Below is general information about the effectiveness of the known ingredients contained in the product Calaguala Fern Leave In Treatment. Some ingredients may not be listed. This information does NOT represent a recommendation for or a test of this specific product as a whole.

ALOE (Aloe Vera)

POSSIBLY EFFECTIVE

Acne. Topical aloe gel may reduce acne lesions when used with topical tretinoin in children and adults with acne. Details: One clinical trial in children and adults with acne shows that topical application of a gel containing aloe 50% in the morning and evening, in addition to topical application of tretinoin 0.025% cream and twice daily cleansing with a medical soap, improves acne lesions by approximately 35% more than using the same treatments without aloe (90124).
Burns. Topical aloe gel or cream may reduce healing time in patients with superficial or partial thickness burns. Details: A meta-analysis of four small clinical trials in patients with second-degree burns shows that use of topical aloe vera reduces time to healing by about 4.4 days when compared to control groups treated with silvadene, silver sulfadiazine, or gauze containing 0.5% chlorhexidine acetate (110209). Most clinical research shows that applying aloe gel or cream topically up to twice daily reduces healing time when compared with silver sulfadiazine (19771,110210,110212), framycetin (19775), vaseline gauze (19773), or placebo (101,97320) in patients with superficial or partial thickness burns. Topical application of aloe cream up to twice daily might also decrease wound size when compared with silver sulfadiazine and framycetin (19771,19775). In addition, some clinical research in patients with burns caused by sulfur mustard shows that applying cream containing aloe and olive oil twice daily for 6 weeks improves pruritus similarly to betamethasone 0.1% cream and may lead to further reductions in excoriation and fissure (19768). However, some preliminary clinical research shows that applying fresh aloe mucilage or aloe extract daily is no more effective than silver sulfadiazine for reducing wound healing time in patients with superficial or partial thickness burns (19774,19776).
Constipation. Oral aloe latex may improve symptoms in patients with constipation; however, the U.S. Food and Drug Administration (FDA) has banned the use of aloe latex as a laxative due to safety concerns. Details: Taking aloe latex 100-200 mg daily or aloe extract 50 mg as a stimulant laxative seems to relieve constipation due to the cathartic effects of the anthraquinones in the aloe (4,5,8). Taking 1-3 capsules of a formulation containing aloe 150 mg, celandine 300 mg, and psyllium 50 mg also seems to improve stool consistency and the mean number of stools in patients with chronic constipation when compared with placebo (19747). However, in 2002, the U.S. FDA banned the use of aloe latex for constipation due to safety concerns (8229,8443).
Diabetes. Oral aloe may reduce blood glucose and glycated hemoglobin (HbA1c) in patients with diabetes. It may be most effective in patients with fasting blood glucose levels of 200 mg/dL or greater. Details: Most clinical research in adults with prediabetes and diabetes shows that taking aloe vera orally can reduce fasting blood glucose by 30-47 mg/dL and HbA1c by 0.41% to 1% (12164,17488,17489,19756,95943,95945,95946). One meta-analysis of 92 patients shows that aloe vera is associated with a larger overall reduction of fasting blood glucose in those with a baseline fasting blood glucose level greater than or equal to 200 mg/dL (95945). Another meta-analysis of 206 patients shows that aloe vera increases high-density lipoprotein (HDL) levels and reduces triglyceride, total cholesterol, and low-density lipoprotein (LDL) levels when compared with placebo in adults with prediabetes and untreated diabetes (95943). These analyses include studies that used multiple forms of aloe vera, including gel powder, extract, raw crushed leaves, and fresh extracted juice, as well as multiple doses ranging from 100-1000 mg of powder and 15-150 mL of juice taken for durations ranging from 4-14 weeks. Significant heterogeneity between studies, small sample sizes, and wide variability in the form and dose of aloe used limit the validity of these findings and the ability to identify an effective dose (95943,95945,95946). Additionally, some research has shown no benefit. This may be due to the different forms and doses of aloe used. One clinical study shows that taking aloe gel as 15 mL twice daily or taking aloe juice 15 mL twice daily does not decrease glucose levels in patients with type 2 diabetes (17420). Other clinical research shows that taking a specific aloe gel complex (Aloe QDM complex, Univera Inc.) containing processed aloe gel 147 mg twice daily for 8 weeks does not affect glycemic indices when compared with placebo in patients with diabetes or prediabetes (90121).
Genital herpes. Topical aloe extract cream may improve healing of genital herpes lesions. Details: Clinical research in males with genital herpes shows that applying a cream containing aloe extract 0.5% three times daily, 5 days weekly, for up to 2 weeks increases healing rates when compared with aloe gel or placebo. The mean time to healing after application of the aloe extract was 5 days, compared with 12 days with placebo (12164,19745,19746).
Lichen planus. Rinsing the mouth with aloe-containing mouthwash or applying aloe gel to the mouth or vulva may reduce pain and improve lesion healing in patients with lichen planus. Details: Clinical research in patients with oral lichen planus shows that using 0.4 mL of mouthwash containing aloe gel 70% three times daily for 12 weeks or applying a gel containing aloe mucilage 70% twice daily for 8 weeks is up to 6 times more likely to reduce pain when compared with placebo (19762,19763,19764). However, these findings are questionable due to poor study design. Other clinical research in patients with oral lichen planus shows that using 2 tablespoons of aloe-containing mouthwash four times daily for a month, or applying aloe gel three times daily for 8 weeks, reduces pain and improves lesion healing at least as much as triamcinolone acetonide paste (0.1% in one study) (19765,90130). However, aloe gel may not be as beneficial as laser therapy. A clinical study in patients with lichen planus show that applying a gel containing aloe powder 500 mg to the affected site three times daily for 2 months is less effective for improving pain and lesion healing than receiving low-level laser therapy twice weekly for 2 months. However, no between-group differences were maintained at 7 months after treatment completion (108722). A network meta-analysis of 2 small clinical trials shows that applying aloe trails only purslane of the herbal agents studied with regard to clinical improvement as measured by the Thongprasom scale. However, aloe does not seem to improve complete clinical resolution, clinical scores, or pain (111640). In patients with vulval lichen planus, clinical research shows that topical application with aloe gel twice daily for 8 weeks increases the number of patients who experience clinical improvement of at least 50% when compared with placebo (19766).
Obesity. Oral aloe gel may modestly reduce body weight and fat mass in adults who are overweight or obese. Details: One clinical trial in overweight and obese adults with diabetes or prediabetes shows that taking a specific aloe gel complex (Aloe QDM complex, Univera Inc.) containing processed aloe gel 147 mg twice daily for 8 weeks reduces body weight by 0.6 kg and fat mass by 1 kg when compared with placebo (90121).
Oral submucous fibrosis. Topical aloe may reduce burning sensations in patients with oral submucous fibrosis, but it may not improve mouth opening, tongue protrusion, or cheek flexibility in these patients. Details: A meta-analysis of five small clinical studies in patients with oral submucous fibrosis shows that topical application of aloe gel for 3 months reduces burning sensation, possibly for up to two months after treatment, when compared with placebo or active control. A network meta-analysis also found that aloe is most effective in reducing burning sensation, ranked only after treatment with corticosteroids, hyaluronidase, and antioxidants (113514). However, aloe does not seem to improve mouth opening, tongue protrusion, or cheek flexibility (100256). One of the studies included in the analysis used a specific aloe gel (Sheetal lab Surat) 5 mg applied topically on each side of the buccal mucosa three times daily for 3 months (90131). All of the studies included in the analysis were conducted in India, so it is unclear if the results are generalizable to other geographic locations. Limited research has also evaluated the use of topical and oral aloe vera in combination. A small clinical study shows that consuming pure aloe vera juice (Hamant Sai, Sun Vision Company) 30 mL twice daily and applying pure aloe vera gel (Hamant Sai, Sun Vision Company) three times daily for 3 months improves cheek flexibility and tongue protrusion when compared with a treatment regimen consisting of intralesional injections of hydrocortisone acetate 25 mg and hyaluronidase 1500 IU weekly for 6 weeks and supplementation with Cap SM Fibro (Indoco Remedies) twice daily for 3 months. Both treatment regimens show an improvement in mouth opening and burning sensation when compared to baseline, with the aloe vera treatment producing a more rapid improvement in burning sensation (95944). It is not clear how this combination of oral and topical aloe vera compares with topical aloe vera alone.
Psoriasis. Topical aloe extract cream may reduce erythema and scaling and improve the resolution of psoriatic plaques in patients with psoriasis. Limited research suggests that topical aloe gel does not have the same effects. Details: Applying aloe extract 0.5% cream topically three times daily for 4 weeks significantly improves and increases the resolution of psoriatic plaques when compared with placebo (101,12096,12164). Aloe extract cream also seems to reduce desquamation, erythema, and infiltration (12096). Other preliminary clinical research shows that applying cream containing aloe mucilage 70% twice daily for 8 weeks improves psoriasis severity more effectively than triamcinolone 0.1% cream, although both treatments had similar effects on dermatology-specific quality of life (19741). Treatment with aloe gel does not seem to improve erythema, infiltration, and desquamation associated with psoriasis when compared with placebo (19748).
Radiation dermatitis. Although some individual research disagrees, topical aloe gel may prevent or delay dermatitis in patients undergoing radiation therapy. Details: A meta-analysis of 7 clinical trials in patients with various types of cancer shows that topical aloe does not reduce the incidence or severity of radiation dermatitis and does not reduce the incidence of erythema, pruritis, moist desquamation, or dry desquamation when compared with control (110325). However, the included studies are limited by a lack of blinding, questionable methodological quality, and a high risk of bias. In contrast, another meta-analysis of generally poor quality randomized controlled trials shows that topical pre-treatment application with aloe as gel, cream, lotion, or fresh plant reduces the risk of radiation dermatitis by 23%, especially mild to moderate radiation dermatitis, when compared with a control group not treated with aloe (110214). One U.S. study included in the analysis shows that applying aloe 98% gel twice daily starting within three days of radiation initiation does not reduce radiation dermatitis when compared with a placebo gel or no treatment (12163). Other research has focused on specific side effects. One clinical trial shows that applying aloe 98% gel three times daily throughout radiation treatment and after treatment does not seem to reduce symptoms of radiation dermatitis in patients being treated for breast cancer (12098). Some research shows that applying aloe 100% gel 6-8 times daily might prolong the time before radiation-related side effects occur, but only when the cumulative dose of radiation is high (>2,700 cGy) (12159). In addition, applying aloe-based gel once daily after radiation treatment is less effective than applying anionic phospholipid-based cream for reducing dryness, erythema, and peeling in children being treated for Hodgkin disease (19855). Aloe has also been evaluated in combination with other ingredients. A small cohort study in patients with head and neck cancer receiving radiation therapy shows that applying aloe 2% and radish 4% gel twice daily until ten days after the last radiotherapy session prevents radiation dermatitis as shown by fewer cases of radiation dermatitis in the 10^th, 30^th, and 35^th radiation sessions when compared with placebo. Furthermore, after the 35th session, the subjects prophylactically treated with the aloe and radish gel had milder grades of radiation dermatitis when compared with control (111662). A preliminary clinical study shows that applying a specific cream product (Radioskin 2, Herbalab di Perazza Massimiliano Company), which contains aloe, ginkgo extract, and metal esculetina, along with another specific cream product (Radioskin 1, Herbalab di Perazza Massimiliano Company), which contains alga atlantica and ethylbisiminomethylguaicolo manganese cloruro, may improve skin hydration and reduce skin toxicity associated with radiation therapy in patients with breast cancer (89727). These creams were applied topically 2-3 times daily at least 3 hours before and after radiation treatment, from 15 days prior to radiation until one month after completion.
Traumatic oral ulcers. Topical aloe gel may prevent oral ulcers after application of orthodontic appliances in adolescents and adults. Details: Clinical research in patients aged 12 years and older shows that applying a gel containing aloe 80% to the gums twice daily for one month after the cementation of orthodontic appliances prevents the development of mouth ulcers when compared with a chlorhexidine gel. Ulcers occurred in about 6% of patients using the aloe gel compared with 81% of those using the chlorhexidine gel. Bleeding and inflammation were also reduced (103305).

INSUFFICIENT RELIABLE EVIDENCE to RATE

Alveolar osteitis. It is unclear if topical aloe or the aloe constituent acemannan is beneficial in patients with alveolar osteitis. Details: One small clinical trial in patients with alveolar osteitis shows that applying a patch containing the aloe constituent acemannan (SaliCept patch) to the tooth socket, once after curettage and irrigation and again 3 days later, reduces pain intensity and improves clinical symptoms when compared with curettage and irrigation alone (19754).
Amenorrhea. Although there has been interest in using oral aloe for amenorrhea, there is insufficient reliable information about the clinical effects of aloe for this purpose.
Anal fissures. It is unclear if topical aloe is beneficial in patients with anal fissures. Details: One small clinical study in patients with chronic anal fissures shows that applying an aloe cream containing 0.5% powdered spray-dried inner aloe leaf juice (Zarban Phyto-Pharmaceutical Co) three times daily for at least 3 weeks, as an adjuvant to sitz baths three times daily, using a laxative, and eating a full fiber diet, improves pain, wound healing, and bleeding severity when compared with placebo (90129).
Asthma. Although there has been interest in using oral aloe for asthma, there is insufficient reliable information about the clinical effects of aloe for this purpose.
Atopic dermatitis (eczema). Topical aloe has only been evaluated in combination with other ingredients; its effect when used alone is unclear. Details: One small clinical trial in patients with atopic dermatitis shows that application of a specific combination cream (Olivederma, Kimi Daru Pharmaceutical Co.) containing aloe gel and virgin olive oil twice daily for 6 weeks improves disease severity and quality of life when compared with betamethasone cream (105020). It is unclear if this effect is due to aloe, olive oil, or the combination.
Breast engorgement. It is unclear if topical aloe improves lactation-associated breast pain. Details: Meta-analyses of 4-5 clinical trials in lactating patients show that use of topical aloe modestly reduces nipple/breast pain and irritation when compared with no treatment, routine care with topical breast milk or breast massage, or treatment with lanolin (110213). However, studies included in this analysis were not specific to breast engorgement.
Burning mouth syndrome. It is unclear if topical aloe is beneficial in patients with burning mouth syndrome. Details: One small clinical trial in patients with chronic burning mouth syndrome shows that applying 0.5 mL of aloe 70% gel to sore areas on the tongue three times daily prior to wearing a tongue protector for 12 weeks does not improve pain or symptoms when compared with placebo gel or using the tongue protector alone in patients with chronic burning mouth syndrome (90127). However, differences in baseline pain ratings between study groups limit the validity of these findings.
Cancer. Oral aloe has only been evaluated in combination with other ingredients; its effect when used alone is unclear. Details: One small clinical study in patients with lung cancer shows that, when administered with standard chemotherapy, three daily doses of 10 mL of a mixture consisting of fresh aloe leaves 300 grams plus honey 500 grams dissolved in 40 mL of alcohol 40% increases the rate of complete response, partial response, or disease control when compared with chemotherapy alone (19752).
Canker sores. Small clinical studies suggest that applying the aloe constituent acemannan to cancer sores may reduce ulcer size, but not pain. However, the effect of aloe is unclear. Details: Meta-analyses of clinical research show that topical aloe is no more effective than control interventions for reducing the size and pain of oral ulcers (110216). Control interventions have included carrier gel or triamcinolone acetonide 0.1% (19751,110216). However, a recent clinical trial shows that topical aloe gel (G.U.M Canker-X, Sunstar Americas, Schaumburg, USA) after meals and before bedtime for 5 days is more effective than amlexanox 5% paste and placebo for reducing pain and the size of canker sores in patients with recurrent symptoms (110215). Other small clinical trials have investigated the effects of fermented aloe or the aloe constituent acemannan. One small clinical trial in adults with recurrent canker sores shows that applying a fermented aloe gel to oral ulcers three times daily seems to accelerate healing time when compared with chitosan gel (104173). Another small clinical trial in patients with canker sores shows that using a wound dressing containing the aloe constituent acemannan (Carrisyn Gel Wound Dressing) shortens the average healing time of canker sores when compared with an oral analgesic (Orabase-Plain) (19750). Other clinical research shows that applying acemannan 0.5% in Carbopol 934P NF three times daily for 7 days reduces ulcer size, but not pain, when compared with Carbopol 934P NF alone in patients with canker sores (90123). However, applying triamcinolone acetonide 0.1% appears to be more effective in reducing pain and similarly effective in reducing ulcer size when compared with acemannan 0.5% (90123).
Common cold. Although there has been interest in using oral aloe for the common cold, there is insufficient reliable information about the clinical effects of aloe for this purpose.
Dental plaque. Using aloe-containing toothpaste may reduce dental plaque in adults; however, it is unclear if this is more effective than fluoride-containing toothpaste. Rinsing with an aloe-containing mouthwash may reduce dental plaque in children. Details: One small clinical trial in adults shows that brushing teeth with a dentifrice containing aloe gel (Forever Bright, Forever Living Products) three times daily for 30 days does not reduce the occurrence of plaque better than a fluoridated dentifrice (Sorriso Dentes Brancos, Kolynos do Brasil), although both treatments seem to show improvement when compared to baseline (19755). Another small clinical study in adults with gingivitis shows that using toothpaste containing aloe daily for 24 weeks reduces plaque more effectively than placebo or triclosan-containing toothpaste (19760). In children aged 8-14 years with mild plaque, using a mouth wash containing aloe vera 7% twice daily for 4 weeks reduced plaque by a large amount when compared with placebo. In addition, it was as effective as chlorhexidine 0.2% (103306).
Depression. Although there has been interest in using oral aloe for depression, there is insufficient reliable information about the clinical effects of aloe for this purpose.
Diabetic foot ulcers. Topical aloe has only been evaluated in combination with other ingredients; its effect when used alone is unclear. Details: One small clinical trial in patients with a stage 1 or 2 diabetic foot ulcer who are receiving oral antibiotics shows that applying a topical product containing aloe and great plantain twice daily for 4 weeks reduces ulcer surface area and time to healing, but not ulcer depth, when compared with antibiotics alone (97323). The effect of applying aloe gel alone without concomitant oral antibiotic therapy is unknown.
Diaper rash. Topical aloe has only been evaluated in combination with other ingredients; its effect when used alone is unclear. Details: One small clinical trial shows that applying a cream containing aloe gel and olive oil three times daily for 5-10 days reduces diaper rash severity in children less than 3 years of age when compared to baseline; however, it does not seem to be as effective as calendula ointment (19779). The validity of this finding is limited by the lack of a placebo group.
Dry mouth. It is unclear if rinsing with an aloe-containing mouthwash is beneficial for dry mouth. Details: In patients with dry mouth related to type 2 diabetes, clinical research shows that an aloe vera 50% mouthwash, as 20 mL swished and spit three times daily for 14 days, modestly reduces symptoms of dry mouth when compared with rinsing with a saline control mouthwash (106068). The validity of this study is limited due to unclear reporting.
Dry skin. Topical aloe or oral aloe sterols may improve some measures of dry skin. However, findings are mixed due to the use of varied formulations and doses. Details: One small clinical trial shows that applying a cream containing freeze-dried aloe extract 0.1% to 0.5% to the skin for 2 weeks increases the amount of water in the stratum corneum, but does not reduce transepidermal water loss, when compared with placebo (19758). Another small clinical study in females with occupational dry skin shows that wearing gloves coated in aloe 8 hours daily for 30 days improves symptoms of dry skin when compared with no treatment (19759). However, it is not clear if the benefits resulted from applying aloe or wearing gloves. One small clinical trial in healthy females shows that consumption of a yogurt containing 500 mg of aloe vera gel powder (0.4 mg of aloe sterol) daily for 12 weeks increases skin hydration, skin elasticity, and collagen content of the dermis while reducing markers of skin fatigue and transepidermal water loss when compared with placebo (95942). However, another study in healthy females shows that taking aloe sterol-enriched aloe extract 0.5 grams daily for 12 weeks does not improve skin hydration when compared with placebo, although redness, itching, collagen content, and transepidermal water loss were improved (101577).
Epilepsy. Although there has been interest in using oral aloe for epilepsy, there is insufficient reliable information about the clinical effects of aloe for this purpose.
Frostbite. Although there has been interest in using topical aloe for frostbite, there is insufficient reliable information about the clinical effects of aloe for this purpose.
Gingivitis. Using aloe-containing toothpaste may reduce gingivitis in adults, but it does not seem to be more effective than fluoride-containing toothpaste. Rinsing with an aloe-containing mouthwash may reduce gingivitis in children. Details: One small clinical trial in adults shows that brushing teeth with a dentifrice containing aloe gel (Forever Bright, Forever Living Products) three times daily for 30 days does not reduce the occurrence of gingivitis more effectively than a fluoridated dentifrice (Sorriso Dentes Brancos, Kolynos do Brasil), although both treatments seem to show improvement when compared to baseline (19755). Another small clinical study in adults with gingivitis shows that using aloe-containing toothpaste daily for 24 weeks reduces gingivitis more effectively than placebo, but not more than triclosan-containing toothpaste (19760). In children aged 8-14 years with mild gingivitis, using a mouthwash containing aloe vera 7% twice daily for 4 weeks reduced gingivitis by a large amount when compared with placebo. In addition, it was as effective as chlorhexidine 0.2% (103306).
Heart failure. It is unclear if oral aloe is beneficial in patients with systolic heart failure. Details: A very small clinical study in adults with moderate to moderately severe chronic systolic heart failure shows that taking aloe vera gel capsules 150 mg twice daily for 8 weeks in addition to standard treatment decreases New York Heart Association (NYHA) functional class, improves Minnesota Living with Heart Failure Questionnaire (MLHFQ) total, physical, emotional, and social scores, and enhances sleep quality but does not reduce the severity of obstructive sleep apnea scores or improve six-minute walk test distance when compared with placebo (111663). The study may have been inadequately powered to detect a difference between groups. Additionally, the validity of these effects may be limited by the small sample size.
Hematopoietic stem cell transplant (HSCT). Oral and topical aloe have only been evaluated in combination with other ingredients; its effect when used alone is unclear. Details: Preliminary clinical research in patients undergoing hematopoietic stem cell transplantation shows that treatment with colostrum and aloe orally (Remargin Colostrum Gastro-Gel, Solimè srl, Cavriago, Reggio Emilia, Italy) and as a mouthwash (Remargin Colostrum OS, Solimè srl, Cavriago, Reggio Emilia, Italy) modestly reduces the risk and duration of severe oral mucositis and febrile neutropenia when compared with historical values. There was no effect on the duration of neutropenia, the length of hospital stay, pain, or duration of medications. All patients were also given standard care. The mouthwash was used after each oral hygiene, and the oral treatment was 3 to 5 times daily depending on symptoms (110211).
Hepatitis. It is unclear if oral aloe is beneficial in patients with hepatitis. Details: One small clinical trial in patients with liver fibrosis primarily caused by hepatitis B or hepatitis C shows that taking a high molecular weight fraction of aloe 0.05 grams three times daily for 12 weeks reduces fibrosis, attenuates liver enzyme activity, and decreases hepatic glutathione content when compared with placebo (19780).
HIV/AIDS. Small clinical studies suggest that oral aloe or the aloe constituent acemannan may not improve CD4 counts or viral load in patients with HIV. Details: One small clinical trial in patients with HIV shows that taking the aloe constituent, acemannan, 400 mg four times daily does not significantly improve CD4 counts, ratio of CD4 to CD8, or viral load when compared with placebo (19851). Another small clinical study in patients with HIV shows that taking aloe gruel 30-40 mL daily does not improve CD4 counts when compared with those treated with antiretroviral therapy, although both groups show similar increases in weight compared to baseline (19852).
Hyperlipidemia. Although there has been interest in using oral aloe for hyperlipidemia, there is insufficient reliable information about the clinical effects of aloe for this purpose.
Hypertrophic scars. Topical aloe has only been evaluated in combination with other ingredients; its effect when used alone is unclear. Details: One small clinical trial in patients undergoing median sternotomy shows that applying a silicone gel containing aloe extract and other herbal extracts (Bangkok Botanica) to postoperative hypertrophic scars for 6 months reduces the height of the scar and improves pliability by a moderate amount when compared with a silicone placebo gel. There was no effect on pigmentation or vascularity (102793). It is unknown whether any benefit is related to aloe, other ingredients, or their combination.
Influenza. Oral aloe has only been evaluated in combination with other ingredients; its effect when used alone is unclear. Details: A small clinical study in healthy adults shows that taking a combination supplement containing aloe vera gel, rosemary, and poria mushrooms twice daily 28 days before administering the influenza vaccine and 28 days after vaccination does not improve immunologic markers or reduce symptom severity, symptom duration, frequency of upper respiratory tract infection symptoms, or the use of cold and flu medications when compared with placebo (111921).
Irritable bowel syndrome (IBS). Small clinical studies suggest that oral aloe extract or juice may not improve symptoms in patients with IBS. Details: Most research suggests that aloe is not effective for improving symptoms of IBS; however, the available evidence is of low-quality, with some studies having high dropout rates or inadequate power to detect significant differences. Two clinical trials show that taking a specific aloe extract (AVH200, Calmino Group AB) 250-500 mg twice daily for 4 weeks does not improve IBS-related symptoms or response rates when compared with placebo (101579,104169), although one of these studies did find a trend toward a higher response rate, defined as a 50% or greater improvement in symptom scores, with aloe over placebo (104169). Also, a pooled analysis of these two studies shows that taking this specific product improves IBS-related pain severity and frequency in patients with diarrhea-prominent IBS (IBS-D) when compared with placebo, but does not seem to improve stool consistency or frequency (108718). Clinical trials evaluating aloe juice 50 mL four times daily for 1 month or 60 mL twice daily for 5 months show no significant improvement in quality of life scores or IBS symptoms when compared with placebo (104170,104171), although one study did find a trend toward improved response in patients with IBS-D (104171). Despite a lack of significant findings in the individual studies, a pooled analysis of the two smallest studies above (104169,104171) shows that aloe extract or juice, taken for 4 weeks, may increase the rate of symptom response by almost 70% when compared with placebo (103307).
Nipple Fissures. It is unclear if application of an aloe poultice improves nipple-related complications of breastfeeding, such as nipple fissures. Details: A clinical study in females who have just given birth and are breastfeeding for the first time shows that applying a poultice containing aloe gel to the nipples after breastfeeding six times daily for 5 days improves nipple eschar when compared with no treatment. Although there were modest improvements in other outcomes, such as redness, fissures, and epidermolysis, these differences were not significant (108721). Participants were instructed to clean with purified water before the next breastfeeding session.
Multiple sclerosis (MS). Although there has been interest in using oral aloe for MS, there is insufficient reliable information about the clinical effects of aloe for this purpose.
Oral mucositis. Small clinical studies suggest that oral aloe juice or application of aloe solution inside the mouth may prevent oral mucositis in patients receiving chemotherapy or radiation. Details: Some clinical research shows that drinking 15 mL of juice containing aloe 80% three times daily during radiation therapy decreases the risk of developing moderate or severe mucositis by approximately 39% when compared with placebo (19767,19964). In addition, in children aged 3-6 years undergoing chemotherapy for leukemia, application of a solution containing aloe 70% twice daily inside the mouth, starting three days before chemotherapy, reduces the severity of oral mucositis and delays its onset by 2 weeks when compared with sodium bicarbonate 5% (103304). Other clinical research in adults with head and neck cancer shows that rinsing and then swallowing 20 mL of a solution containing aloe juice 94.5% four times daily throughout the course of radiation therapy does not prevent mucositis when compared with placebo (19963). However, this study was not adequately powered to detect significant differences between study groups. Aloe has also been evaluated in combination with other ingredients for the treatment of oral mucositis. Preliminary clinical research in patients undergoing hematopoietic stem cell transplantation shows that treatment with colostrum and aloe orally (Remargin Colostrum Gastro-Gel, Solimè srl, Cavriago, Reggio Emilia, Italy) and as a mouthwash (Remargin Colostrum OS, Solimè srl, Cavriago, Reggio Emilia, Italy) modestly reduces the risk and duration of severe oral mucositis when compared with historical values. There was no effect on overall risk or time of onset of mucositis. All patients were also given standard care. The mouthwash was used after each oral hygiene, and the oral treatment was 3 to 5 times daily depending on symptoms (110211). Another small clinical study in adults with head and neck cancer receiving radiotherapy shows that rinsing with 5 mL of a mouthwash containing aloe, German chamomile, peppermint oil, and honey 3 times daily for 60 seconds for 6 weeks starting on the first day of radiotherapy reduces oral mucositis incidence, severity, and pain when compared with chlorhexidine and placebo (111291). It is unclear if these findings are due to aloe, other ingredients, or the combination.
Osteoarthritis. Although there has been interest in using oral and topical aloe for osteoarthritis, there is insufficient reliable information about the clinical effects of aloe for this purpose.
Peptic ulcers. Although there has been interest in using oral aloe for peptic ulcers, there is insufficient reliable information about the clinical effects of aloe for this purpose.
Periodontitis. It is unclear if application of aloe inside the mouth is beneficial for chronic periodontitis. Details: A meta-analysis of small clinical studies in patients with chronic periodontitis shows that using various aloe-containing gels, mouthwashes, and toothpastes improves plaque index when compared with placebo or other treatments (i.e., chlorhexidine rinse, metformin, and tea tree oil). The effect of these aloe products on gingival index could not be determined (108719). The validity of this finding is limited by the variety of aloe formulations and comparators used in the included studies.
Pressure ulcers. It is unclear if topical aloe is beneficial for the prevention or treatment of pressure ulcers. Details: One small clinical study shows that applying a gel containing the aloe constituent acemannan to pressure ulcers daily for 10 weeks does not reduce the time to healing when compared with management with moist saline gauze (12160,19853). Other clinical research shows that cleansing wounds with a saline spray containing aloe, silver chloride, and decyl glucoside for 2 weeks improves pressure ulcer healing when compared with isotonic saline spray (19854). It is unclear if this improvement is due to aloe, other ingredients, or the combination in the spray. Aloe has also been evaluated for the prevention of pressure ulcers. A small clinical study in hospitalized patients in an orthopedic ward shows that applying aloe vera gel to the hips, sacrum, and heels twice daily for 10 days reduces pressure ulcer occurrence to 3 of 39 patients, compared to 12 of 38 patients of those receiving placebo (98816). However, methodological limitations with this study, including differences in how the gels were applied, limit the reliability of these results. A clinical study in hospitalized patients receiving intensive care has evaluated either aloe gel 94%, olive oil 100%, or a compounded product containing aloe vera and olive oil in a 3:2 ratio, applied to pressure areas as 10-15 mL every 8 hours. At the end of 30 days, pressure ulcers occurred in 17% of patients receiving the combination product, 20% receiving olive oil, 33% receiving aloe gel, and 37% receiving standard care, suggesting that any benefit may be due to olive oil (108723).
Radiation proctopathy. It is unclear if topical aloe is beneficial for the prevention or treatment of radiation proctopathy. Details: One very small clinical study in females with radiation proctopathy shows that applying 1 gram of an ointment containing aloe vera 3% rectally twice daily in conjunction with taking sulfasalazine 500 mg four times daily for 4 weeks modestly reduces diarrhea, fecal urgency, radiation toxicity, and clinical symptoms when compared with sulfasalazine alone (95941). This same product, applied twice daily for 6 weeks starting on the first day of radiotherapy, has also been evaluated for the prevention of radiation proctopathy. One small clinical study in patients with pelvic cancer shows that applying this ointment prevents proctopathy-related diarrhea, rectal bleeding, and fecal urgency when compared with placebo. Proctopathy-related symptoms occurred in 5% of patients using aloe, compared with 65% of those using placebo. However, there was no difference in rectal pain, constipation, or symptoms of cystitis between groups (101578). A very small clinical study in patients with colorectal cancer shows that applying this ointment prevents proctopathy-related diarrhea and reduces proctopathy severity, but does not improve rectal bleeding, rectal pain, fecal urgency, or symptoms of cystitis, when compared with placebo (108717). Reasons for discrepancies are unclear but might relate to differences in cancer diagnosis and radiation regimens.
Scabies. It is unclear if topical aloe is beneficial in patients with scabies. Details: One small open-label clinical study in children and adults with scabies shows that application of crude aloe gel for 3 consecutive days, repeated again after one week, may reduce itching and lesions similar to benzyl benzoate lotion in patients with scabies when compared to baseline (19769). The validity of this finding is limited by the lack of a placebo group.
Seborrheic dermatitis. It is unclear if topical aloe is beneficial in patients with seborrheic dermatitis. Details: One small clinical study in adults with seborrheic dermatitis shows that applying aloe 30% emulsion twice daily for 4-6 weeks reduces scaling, itching, and the number of sites involved, but not erythema, when compared with placebo (19749).
Stretch marks (striae gravidarum). It is unclear if topical aloe is effective for the prevention or treatment of stretch marks. Details: One small clinical trial in nulliparous patients shows that topical application of a cream containing aloe twice daily, starting at gestational week 16-18, reduces erythema and itching related to abdominal stretch marks, but does not seem to decrease the number of stretch marks, when compared with a base cream (97322). Aloe gel has also been evaluated in combination with fractional carbon dioxide (CO2) laser treatments. A small clinical trial shows that applying a gel containing aloe 87.4% twice daily for up to one month after each of three CO2 laser treatments improves the texture of the skin for up to 6 months after the last laser treatment when compared to baseline. This was as effective as topical recombinant human epidermal growth factor (rhEGF) and CO2 laser treatments. However, when specific sites were examined, only the texture of stretch marks on the buttocks were improved, and these improvements were less than those seen with rhEGF (101580). The effect of aloe for the prevention of stretch marks is unknown.
Sunburn. Although there has been interest in using topical aloe for sunburn, there is insufficient reliable information about the clinical effects of aloe for this purpose.
Tungiasis. Topical aloe has only been evaluated in combination with other ingredients; its effect when used alone is unclear. Details: One clinical study shows that applying a product containing coconut oil, jojoba oil, and aloe leaf extract (Zanzarin, Engelhard Arzneimittel GmbH & Co. KG) to the feet twice daily for one-week intervals seems to reduce the number of embedded sandfleas in individuals with tungiasis when compared with a control group (19778). It is not clear if this effect is due to aloe, the other ingredients, or the combination.
Ulcerative colitis. It is unclear if oral aloe gel is beneficial in patients with ulcerative colitis. Details: One small clinical trial in patients with mild to moderate ulcerative colitis shows that taking aloe gel for 4 weeks, starting at 25-50 mL twice daily for the first 3 days and increasing to 100 mL twice daily thereafter, reduces symptoms when compared with placebo (11984).
Vaginitis. It is unclear if topical aloe is beneficial for vaginitis. Details: One small clinical trial in postmenopausal patients with atrophic vaginitis shows that applying 5 mg of a vaginal cream containing aloe gel 2% nightly for 2 weeks, then 3 nights per week for 4 weeks, reduces vaginal dryness, burning, and pain during intercourse and improves measures of vaginal health and maturity when compared to baseline. These effects were similar to those seen with estrogen vaginal cream (104175).
Varicose veins. Although there has been interest in using oral and topical aloe for varicose veins, there is insufficient reliable information about the clinical effects of aloe for this purpose.
Wound healing. There is conflicting evidence about the effectiveness of topical aloe products for improving wound healing. These conflicting findings may be due to differences in study designs, products used, and application practices. Details: One small clinical study shows that applying aloe gel to a caesarean wound after surgery, followed by a dry gauze, improves wound healing over the first 24 hours when compared with the dry gauze alone (90128). However, other clinical research in a small number of patients undergoing gynecologic surgery or cesarean section shows that applying an aloe gel extract (Carrington Dermal Wound Gel) to surgical wounds may actually delay wound healing (11982). Another small clinical trial shows that applying a formulation of aloe gel 0.5% cream (Zarband, Phytopharmaceutical Co.) to hemorrhoidectomy wounds three times daily for 4 weeks improves healing rates and pain relief scores and decreases intake of narcotic analgesics when compared with placebo (17418). However, another clinical trial in patients with biopsy wounds shows that application of a hydrogel containing the aloe constituent, acemannan (Carrasyn, Carrington hydrogel), does not improve wound epithelialization, wound infections, or pain when compared with conventional therapy (19856). Additionally, there is contradictory evidence about the effectiveness of aloe for improving skin graft donor site healing. One small clinical study shows that applying aloe gel 87.4% daily to split-thickness skin graft donor sites reduces time to complete healing by about 2 days when compared with placebo (97320). However, another small clinical study shows that applying aloe cream three times daily to split-thickness skin graft donor sites does not improve healing time when compared with placebo (97321).
Wrinkled skin. Although there has been interest in using topical aloe for wrinkled skin, there is insufficient reliable information about the clinical effects of aloe for this purpose. More evidence is needed to rate aloe for these uses.

MARITIME PINE (Pine bark extract)

POSSIBLY EFFECTIVE

Asthma. Oral maritime pine bark extract, taken as an adjunct to conventional asthma medications, may improve symptoms and reduce rescue inhaler use in patients with asthma. Details: Three small clinical studies in children and adults with asthma of varying severity show that taking a standardized extract of maritime pine bark (Pycnogenol, Horphag Research) 1 mg/lb body weight or 100 mg daily in addition to conventional asthma medications increases peak expiratory flow, decreases asthma symptoms, and decreases the need for rescue medications when compared with conventional therapy alone (13120,50863,50926). Maritime pine bark extract has not been studied as monotherapy for asthma and should not be used in place of conventional medicine for this purpose.
Chronic venous insufficiency (CVI). Oral maritime pine bark extract may improve leg pain and heaviness and reduce edema in patients with CVI. Details: Several clinical studies in patients with CVI show that taking a standardized extract of maritime pine bark (Pycnogenol, Horphag Research) reduces edema, the rate of ankle swelling, and symptoms of leg pain and heaviness when used for 3-12 weeks. The most commonly used dose is 100-120 mg three times daily (2451,2462,2493,7693,50892). However, lower doses of 50 mg three times daily (16906,50892,50900,50915) or 45-100 mg once daily also seem to be effective (2435,97401). When compared with the use of below-knee compression stockings worn throughout the day, maritime pine bark reduces induration and the rate of ankle swelling when compared to baseline in patients with CVI. While both treatments reduce venous edema and pain when compared with baseline, a more pronounced reduction is seen in patients taking the maritime pine bark extract (97401). Other clinical research in adults who have had CVI for more than 3 years shows that taking the same extract, 50 mg three times daily for 8 weeks, in addition to wearing compression stockings, improves microcirculation and subjective symptom scores when compared with compression stockings alone (103616). However, compliance with the use of compression stockings in this study was poor.
Osteoarthritis. Small clinical studies suggest that oral maritime pine bark extract may modestly improve symptoms and reduce the need for analgesics in patients with knee osteoarthritis. Details: Two small clinical studies in patients with knee osteoarthritis shows that taking a standardized extract of maritime pine bark (Pycnogenol, Horphag Research) 100-150 mg daily for 3 months reduces overall osteoarthritis symptoms, pain, and the use of anti-inflammatory medication when compared with placebo (50903,50905). Topical maritime pine bark has also been evaluated. Observational research in patients with knee osteoarthritis found that applying standardized extract of maritime pine bark (Pycnogenol, Horphag Research) 220 mg, as two patches daily, for three weeks is associated with reduced pain and reduced need for rescue analgesics when compared with control (100356).

POSSIBLY INEFFECTIVE

Hyperlipidemia. Oral maritime pine bark extract may not improve lipid levels in patients with hyperlipidemia. Details: Although individual clinical trials have shown mixed results (7693,91965,97408), a meta-analysis of 4 small clinical trials in patients with hyperlipidemia shows that taking a standardized extract of maritime pine bark (Pycnogenol, Horphag Research) 100-150 mg daily for 4-24 weeks does not reduce total cholesterol, low-density lipoprotein (LDL) cholesterol, or triglyceride levels when compared with a control (100357).

INSUFFICIENT RELIABLE EVIDENCE to RATE

Age-related cognitive decline. It is unclear if oral maritime pine bark extract is beneficial in elderly patients with age-related cognitive decline. Details: One observational registry study in healthy elderly patients ages 55-70 years has found that taking a standardized extract of maritime pine bark (Pycnogenol, Horphag Research) 100 mg daily for 12 months is associated with improved cognitive function, mental performance, and attention when compared with matched controls (97405). However, the validity of these findings is limited by the unblinded, non-randomized nature of the study. Also, a small clinical study in healthy elderly patients 60-85 years of age shows that taking the same extract, 150 mg daily for 3 months, improves spatial working memory, but not numeric working memory, episodic memory, attention, or psychomotor performance, when compared with placebo (50906).
Aging skin. Although there has been interest in using oral and topical maritime pine for aging skin, there is insufficient reliable information about the clinical effects of maritime pine for this purpose.
Allergic rhinitis (hay fever). It is unclear if oral maritime pine bark extract is beneficial in people with allergic rhinitis. Details: A small clinical study in patients with birch allergies shows that taking a standardized extract of maritime pine bark (Pycnogenol, Horphag Research) 50 mg twice daily, starting at least 5 weeks before allergy season, decreases nasal symptoms associated with birch allergies when compared with placebo (17300).
Androgenic alopecia. It is unclear if oral maritime pine bark is beneficial for androgenic alopecia. Details: A small clinical study in postmenopausal patients conducted in China shows that taking maritime pine bark (Pycnogenol, Horphag Research) 150 mg daily for 6 months improves hair density when compared to baseline (112713). However, the interpretation of these findings is limited by the lack of a statistical comparison to the placebo group.
Antidepressant-induced sexual dysfunction. It is unclear if oral maritime pine bark is beneficial for improving sexual function in adults taking escitalopram. Details: A small, open-label clinical study shows that taking standardized extract of maritime pine bark (Pycnogenol, Horphag Research) 50 mg daily for 4 months with escitalopram 10-20 mg daily seems to improve sexual dysfunction when compared with escitalopram alone (100361).
Atherosclerosis. Oral maritime pine bark extract has only been evaluated in combination with other ingredients; its effect when used alone is unclear. Details: A non-randomized clinical trial in adults with atherosclerosis shows that taking a specific maritime pine bark product (Pycnogenol, Horphag Research) 150 mg and gotu kola 225 mg, in two divided doses daily for 3 months, reduces plaque height and length and increases plaque echogenicity and stability when compared to control (97030). However, these benefits may be at least partially due to gotu kola. Another non-randomized clinical study in adults with atherosclerotic plaques and no other cardiovascular risk factors shows that taking Pycnogenol 100 mg and gotu kola extract 100 mg daily for up to 4 years reduces plaque progression and increases plaque echogenicity to a greater extent than Pycnogenol alone or no treatment at all. Taking Pycnogenol with gotu kola is also associated with a reduced rate of clinical vascular events, including angina, myocardial infarction, minor transient ischemic attacks (TIAs), and minor strokes, when compared with taking Pycnogenol alone or receiving no treatment at all (97029).
Athletic performance. It is unclear if oral maritime pine bark extract is beneficial for improving exercise capacity in recreationally trained adults; the available evidence is conflicting. Details: One small clinical study shows that taking a standardized extract of maritime pine bark (Pycnogenol, Horphag Research) 200 mg orally daily for 30 days improves exercise capacity during a treadmill test in recreational athletes aged 20-35 years (2554). Additionally, an observational registry study found that taking this same maritime pine bark extract 100 mg orally daily for 8 weeks along with training improves performance in the Army Physical Fitness Test, including reducing two-mile treadmill time by about 45-60 seconds and increasing the number of push-ups and sit-ups by about 5-7 when compared to control training alone. Taking this maritime pine bark extract during training also appears to improve total triathlon time by about 6 minutes when compared with training alone (91966). However, the validity of this finding is limited by the unblinded, non-randomized nature of the study. Additionally, a small study in college-age males who exercise regularly shows that taking the same maritime pine bark extract 800 mg daily, starting 14 days prior to a cycle ergometer test and continuing for 2 days after, does not improve maximum oxygen consumption or power generated in the test when compared with placebo (103617). Maritime pine extract has also been studied in combination with other ingredients. A small clinical study in non-professional athletes shows that taking a combination product (PycnoRacer, Kobayashi Pharmaceutical Company) containing maritime pine extract 15 mg, L-leucine 0.6 grams, L-arginine 0.3 grams, L-isoleucine 0.3 grams, and L-valine 0.3 grams four times daily for 3 weeks during training improves running distance by about 19%, compared with 9% in athletes drinking water plus Gatorade. Maritime pine park also improved maximal oxygen consumption and reduced subjective scores of muscle pain and cramps when compared with water and Gatorade (103613). It is unclear if these benefits are due to maritime pine, other ingredients, or the combination.
Attention deficit-hyperactivity disorder (ADHD). It is unclear if oral maritime pine bark extract is beneficial in children or adults with ADHD. Details: A small clinical study in adults with ADHD shows that taking a standardized extract of maritime pine bark (Pycnogenol, Horphag Research) does not seem to improve ADHD symptoms when compared with placebo (9984). However, a small clinical study in children with ADHD shows that taking this standardized maritime pine bark extract 1 mg/kg daily for one month appears to improve attention and hyperactivity scores when compared with placebo (50891).
Behcet syndrome. It is unclear if oral maritime pine bark extract is beneficial in patients with Behcet syndrome. Details: A small clinical study in patients with Behcet syndrome shows that taking a standardized extract of maritime pine bark (Pycnogenol, Horphag Research) 150 mg daily for 3 weeks reduces skin ulcer size and improves self-reported symptoms of burning and pain when compared to baseline (100358). The validity of these findings is limited by the lack of a comparator group.
Benign prostatic hyperplasia (BPH). It is unclear if oral maritime pine bark extract is beneficial in patients with BPH. Details: A small observational registry study in patients with BPH found that taking a standardized extract of maritime pine bark (Pycnogenol, Horphag Research) 150 mg daily for 8 weeks is associated with modest improvement of symptoms such as bladder emptying, urgency, flow, straining, and nocturia (100359). This study was limited by small size, reporting inaccuracies, and its unblinded, non-randomized design.
Cognitive function. Small clinical studies suggest that oral maritime pine bark extract might improve cognitive function in healthy adults. Details: A small observational registry study in healthy adults aged 30-55 years found that taking a standardized extract of maritime pine bark (Pycnogenol, Horphag Research) 150 mg daily for 12 weeks is associated with slightly improved memory and cognition when compared with matched controls (97410). However, the validity of these findings is limited by the unblinded, non-randomized nature of the study. A small clinical study in healthy college students also shows that taking the same extract 100 mg daily for 2 months seems to reduce failed tests by 4.5% and improve average test scores by about 8% when compared with control (50928).
Cognitive impairment. It is unclear if oral maritime pine bark extract improves cognitive function in patients with mild cognitive impairment. Details: An observational registry study in adults with mild cognitive impairment found that taking a standardized extract of maritime pine bark (Pycnogenol, Horphag Research) 150 mg daily for 8 weeks improves global cognitive function when compared to no supplementation. All patients in this study also received standard management of mild cognitive impairment, which included lifestyle modifications such as improved sleep, physical exercise, reduced sugar and salt intake, lowering cardiovascular risk factors, and avoiding use of stimulants or depressants (97406). However, the validity of these findings is limited by the unblinded, non-randomized nature of the study.
Common cold. It is unclear if oral maritime pine bark extract is beneficial in the treatment of the common cold. Details: An observational registry study in otherwise healthy adults with a cold found that taking a standardized extract of maritime pine bark (Pycnogenol, Horphag Research) 50 mg twice daily, along with best management for colds, is associated with about one less day of a perceived cold when compared to "best management" alone. This standardized maritime pine bark extract is also linked to reduced use of over-the-counter products to manage symptoms in cases of colds lasting longer than 4 days (91962). However, the validity of these findings is limited by the unblinded, non-randomized nature of the study.
Dental plaque. It is unclear if chewing gum containing maritime pine bark extract can reduce dental plaque. Details: A small clinical study shows that chewing a minimum of six pieces of gum containing a standardized extract of maritime pine bark (Pycnogenol, Horphag Research) 5 mg daily for 14 days reduces gingival bleeding by 55% and prevents an increase in gingival plaque when compared with a control sugar-free gum (50857).
Diabetes. Small clinical studies suggest that oral maritime pine bark extract may modestly improve glycemic control in patients with type 2 diabetes. Details: Three small clinical studies in patients with type 2 diabetes show that taking a standardized extract of maritime pine bark (Pycnogenol, Horphag Research) 50-200 mg daily for 3-12 weeks modestly decreases blood glucose and glycated hemoglobin (HbA1C) levels when compared with placebo (15521,15522,50908). Another small clinical trial in patients with type 2 diabetes and microalbuminuria shows that taking a different standardized maritime pine bark extract (Oligopin, DRT Group) 100 mg daily for 8 weeks reduces HbA1c by around 1%, but does not reduce fasting blood glucose, when compared with placebo (105781).
Diabetic foot ulcers. It is unclear if oral or topical maritime pine bark extract is beneficial for diabetic foot ulcers. Details: A small clinical study in patients with diabetic foot ulcers shows that taking a standardized extract of maritime pine bark (Pycnogenol, Horphag Research) 150 mg daily orally as well as applying the extract topically 100 mg daily heals ulcers in 89% of subjects compared with 61% of control subjects. Using oral or topical maritime pine bark extract alone seems to result in complete ulcer healing in about 85% of subjects (50896).
Diabetic microangiopathy. It is unclear if oral maritime pine bark extract is beneficial in patients with diabetic microangiopathy. Details: A small, unblinded clinical study in patients with diabetic microangiopathy, symptoms of neuropathy, and edema in the absence of severe cardiovascular disease shows that taking a standardized extract of maritime pine bark (Pycnogenol, Horphag Research) 50 mg three times daily for 4 weeks improves microcirculation (measured by laser Doppler flowmetry) and symptoms when compared with no treatment (15523).
Diabetic retinopathy. It is unclear if oral maritime pine bark extract is beneficial in patients with diabetic retinopathy. Details: A small, unblinded clinical study in patients with retinopathy due to various causes, including diabetes, atherosclerosis, or central venous thrombosis, shows that taking a standardized extract of maritime pine bark (Pycnogenol, Horphag Research) 50 mg three times daily for 2 months may slow or prevent further deterioration of retinal function when compared with no treatment (2536).
Dry mouth. It is unclear if oral maritime pine bark extract is beneficial in patients with dry mouth. Details: Two small observational studies in otherwise healthy adults or patients with diabetes suggest that adding a standardized extract of maritime pine bark (Pycnogenol, Horphag Research) for 2 weeks along with standard saliva supplements is associated with improvement in patient-reported mouth dryness, salivary flow, and the number of small mucosal breaks when compared with saliva supplements alone. One study dosed maritime pine bark extract 150 mg orally daily and the other used a spray formulation dosed 10 mg six times daily (103612,112714). However, the validity of these findings is limited by the unblinded, non-randomized nature of the studies.
Dysmenorrhea. It is unclear if oral maritime pine bark extract is beneficial in patients with dysmenorrhea. Details: Two small clinical studies in patients with dysmenorrhea show that taking a standardized extract of maritime pine bark (Pycnogenol, Horphag Research) 30-60 daily for up to 3 menstrual cycles reduces pain when compared to baseline (15424,50904). The validity of this finding is limited by the lack of a comparator group.
Erectile dysfunction (ED). Small clinical studies suggest that oral maritime pine bark extract, taken alone or in combination with L-arginine, may modestly improve sexual function in patients with ED. Details: Several small clinical studies in adults with ED show that taking a standardized extract of maritime pine bark (Pycnogenol, Horphag Research) at a dose of 120 mg daily for 3 months, either alone (12012) or in combination with L-arginine (10416,32149,50924), might improve sexual function when compared with placebo or baseline measurements. It seems to take up to 3 months of treatment for significant improvement. Similarly, a meta-analysis of 2 small clinical studies in males with mild to moderate ED shows that taking maritime pine 80 mg with L- arginine daily for 1-6 months improves International Index of Erectile Dysfunction scores by 9 points when compared with control (112715). It is unclear if this effect is from maritime pine, L-arginine, or the combination.
Exercise-induced muscle soreness. Oral maritime pine bark extract has only been evaluated in combination with other ingredients; its effect when used alone is unclear. Details: A small clinical study in non-professional athletes shows that taking a combination product (PycnoRacer, Kobayashi Pharmaceutical Company) containing maritime pine extract 15 mg, L-leucine 0.6 grams, L-arginine 0.3 grams, L-isoleucine 0.3 grams, and L-valine 0.3 grams four times daily for 3 weeks during training improves subjective scores for muscle pain and cramps when compared with water plus Gatorade (103613). It is unclear if these benefits are due to maritime pine, other ingredients, or the combination.
Glaucoma. Oral maritime pine has only been evaluated in combination with other ingredients; its effects when used alone is unclear. Details: One small, unblinded clinical trial in Japanese patients with open-angle glaucoma shows that taking a specific product (Sante Glagenox, Saten Pharmaceutical Co. Ltd.) containing maritime pine extract 40 mg and bilberry fruit extract 90 mg daily for 4 weeks reduces intraocular pressure by 8.7% when compared to baseline (104192). The validity of this finding is limited by the lack of a comparator group.
Heart failure. Oral maritime pine bark extract has only been evaluated in combination with other ingredients; its effect when used alone is unclear. Details: A small observational study in patients with mild to moderate heart failure has found that taking a specific combination product (PycnoQ10, Natural Health Science Inc.) containing a standardized extract of maritime pine bark (Pycnogenol, Horphag Research) and coenzyme Q10 for 12 weeks is associated with improved exercise capacity and heart function (44178). It is unclear if these findings are due to maritime pine, coenzyme Q10, or the combination.
Hemorrhoids. It is unclear if oral or topical maritime pine bark extract is beneficial in patients with hemorrhoids. Details: A small clinical study in patients with acute hemorrhoidal episodes shows that taking a standardized extract of maritime pine bark (Pycnogenol, Horphag Research) 150-300 mg daily orally, alone or in combination with a cream containing 0.5% standardized maritime pine bark extract (Pycnogenol, Horphag Research) for 7 days, improves both quality of life and hemorrhoidal symptoms when compared with placebo tablets/cream (50912). Additionally, an observational registry study in postpartum adults with internal or external hemorrhoids found that taking this same extract of maritime pine bark 150 mg daily for 6 months, in conjunction with standard hemorrhoid care, is associated with improved symptoms, including thrombosis, pain, swelling, and bleeding, when compared to standard care alone (97416). However, the validity of these findings is limited by the unblinded, non-randomized nature of the study.
Hypertension. It is unclear if oral maritime pine bark reduces blood pressure; the available research is conflicting. Details: A very small clinical study in patients with mild hypertension (systolic 140-159 mm Hg; diastolic 90-99 mm Hg) shows that taking a standardized extract of maritime pine bark (Pycnogenol, Horphag Research) 200 mg daily for 8 weeks may modestly reduce systolic, but not diastolic, blood pressure when compared with placebo (10214). Another very small study in hypertensive patients treated with ramipril, taking this same standardized maritime pine bark extract 50 mg three times daily for 6 months, appears to further reduce diastolic, but not systolic, blood pressure (50913). Conflicting results have been reported with other maritime pine products. A small clinical study in adults with untreated, mild hypertension shows that taking a different standardized extract of maritime pine (Oligopin, DRT Group), 75 mg twice daily for 5 weeks, does not lower systolic or diastolic blood pressure when compared with placebo (97407). Also, a small clinical study in obese patients with prehypertension or hypertension shows that taking a different maritime pine bark extract (Toyo-FVG, Toyo Bio-Pharma) 200 mg daily for 12 weeks does not lower systolic or diastolic blood pressure when compared with placebo (50919). Results of meta-analyses are also contradictory. An analysis of 7 clinical trials using maritime pine bark extract 90-200 mg daily for 2-24 weeks shows no significant effect overall on systolic or diastolic blood pressure, mean arterial pressure, or pulse pressure (103609). However, an analysis of 12 trials using doses of 60-200 mg daily for 4-24 weeks shows a mean reduction of about 3 mmHg in systolic blood pressure, and about 2 mmHg in diastolic blood pressure. There was high heterogeneity between the studies, and the effect on diastolic blood pressure was only seen with a treatment duration of at least 12 weeks (103610).
Idiopathic interstitial pneumonia. Oral maritime pine bark extract has only been evaluated in combination with other ingredients; its effect when used alone is unclear. Details: A small observational registry study in males less than 65 years old with idiopathic interstitial pneumonia has found that taking a standardized extract of maritime pine bark (Pycnogenol, Horphag Research) 50 mg three times daily in combination with gotu kola (Centellicum; Horphag Research) 225 mg three times daily for 8 months is associated with a modest improvement in Karnofsky Performance Scale scores and a reduction in fatigue when compared with pirfenidone (108862). However, the validity of these findings is limited by the unblinded, non-randomized nature of the study.
Irritable bowel syndrome (IBS). It is unclear if oral maritime pine bark extract is beneficial in patients with IBS. Details: An observational registry study in adults with idiopathic IBS found that taking a standardized extract of maritime pine bark (Pycnogenol, Horphag Research) 150 mg daily for 4 weeks, in conjunction with standard treatment, is associated with reduced abdominal pain, cramps, and the use of medical care and rescue medications when compared to standard treatment alone. In both groups, standard treatment included specific nutritional recommendations and Buscopan Compositum, hyoscine-N-butylbromide, or acetaminophen for pain relief (97402). However, the validity of these findings is limited by the unblinded, non-randomized nature of the study.
Jet lag. It is unclear if oral maritime pine bark extract can prevent or treat jet leg. Details: An observational registry study found that taking a standardized extract of maritime pine bark (Pycnogenol, Horphag Research) 150 mg daily for up to 10 days, starting 3 days before a plane flight, is associated with reduced signs and symptoms of jet lag when compared to control (97437). Additionally, a small clinical study shows that taking this extract 50 mg three times daily for 7 days, starting 2 days before a plane flight, reduces jet lag symptoms and the average duration of symptoms by a little over 1 day when compared with placebo (97412).
Leg cramps. It is unclear if oral maritime pine bark extract is beneficial for leg cramps. Details: A small clinical study in patients experiencing at least 4 episodes of leg cramps per week associated with athletic activity, venous insufficiency, or an unknown cause shows that taking a standardized extract of maritime pine bark (Pycnogenol, Horphag Research) 200 mg daily for 4 weeks may decrease the incidence of leg cramps when compared to baseline (15524). The validity of this finding is limited by the lack of a comparator group.
Male infertility. Although there has been interest in using oral maritime pine for male infertility, there is insufficient reliable information about the clinical effects of maritime pine for this purpose.
Melasma. It is unclear if oral maritime pine bark extract is beneficial for melasma. Details: A small clinical study in females with melasma shows that taking a standardized extract of maritime pine bark (Pycnogenol, Horphag Research) 75 mg twice daily for 60 days, along with topical application of sunscreen during the day and a triple cream containing hydroquinone, tretinoin, and fluocinolone at night, improves scores related to melasma severity and aesthetics, but not quality of life, when compared with placebo plus sunscreen and triple cream (105782).
Meniere disease. It is unclear if oral maritime pine bark extract is beneficial in patients with Meniere disease. Details: Observational registry research in patients with Meniere disease found that taking a standardized extract of maritime pine bark (Pycnogenol, Horphag Research) 150 mg daily along with standard treatment is associated with a greater reduction in the severity of tinnitus and the number of work-days lost when compared with standard treatment alone. After 6 months of treatment, about 87% of patients taking maritime pine bark were asymptomatic, compared to about 35% of patients receiving standard treatment alone (97413). However, the validity of these findings is limited by the unblinded, non-randomized nature of the study.
Menopausal symptoms. Small clinical studies suggest that oral maritime pine bark extract might improve some menopausal symptoms. Details: Several small clinical studies in patients with menopausal symptoms shows that taking a standardized extract of maritime pine bark (Pycnogenol, Horphag Research) 60-200 mg daily for 2-6 months modestly reduces perimenopausal symptoms, including tiredness, headache, depression and anxiety, sleep disturbances, vaginal dryness, hot flashes, and loss of memory, when compared with placebo or control (14899,50927,50945).
Metabolic syndrome. It is unclear if oral maritime pine bark extract is beneficial in patients with metabolic syndrome. Details: A small clinical study in patients with metabolic syndrome shows that taking a standardized extract of maritime pine bark (Pycnogenol, Horphag Research) 50 mg three times daily for 6 months lowers triglyceride levels by 46 mg/dL, increases high-density lipoprotein (HDL) cholesterol levels by about 10 mg/dL, reduces fasting plasma glucose by 18 mg/dL, and lowers systolic and diastolic blood pressure by 7 mmHg and 5 mmHg, respectively, when compared to baseline. The validity of these findings is limited by the lack of statistical comparison to a control group. Taking the maritime pine bark extract was also associated with a reduction in the percentage of patients presenting with five risk factors of metabolic syndrome (91960).
Oral mucositis. It is unclear if topical maritime pine bark extract is beneficial in children with chemotherapy-related oral mucositis. Details: A small clinical study in children 6-15 years of age with chemotherapy-related oral mucositis shows that application of a solution containing a standardized extract of maritime pine bark (Pycnogenol, Horphag Research) 1 mg/kg in three divided doses daily for one week promotes complete healing in 58% of patients and improved healing in 38% of patients. This improvement was significantly greater than treatment with glycerine solution and similar to treatment with vitamin E solution (91964).
Osteopenia. It is unclear if maritime pine bark extract is beneficial in patients with osteopenia. Details: A small clinical study in postmenopausal adults with osteopenia shows that taking a standardized extract of maritime pine bark (Oligopin, DRT Group) 150 mg daily for 12 weeks improves markers of bone turnover when compared with placebo (105783). It is unknown if maritime pine bark extract improves bone mineral density or reduces the risk of fractures in patients with osteopenia.
Parkinson disease. It is unclear if oral maritime pine bark extract is beneficial in patients with Parkinson disease. Details: Two small observational studies in adults with mild to moderate Parkinson disease suggest that taking a standardized extract of maritime pine bark (Pycnogenol, Horphag Research) 150 mg daily for 4 or 8 weeks in conjunction with carbidopa/levodopa therapy is associated with a reduction in scores for tremor, bradykinesia, and rigidity when compared with carbidopa/levodopa therapy alone. Maritime pine is also associated with an increase in the Karnofsky Performance Status Scale score from approximately 75 (cares for self, unable to carry on normal activity or do active work) to approximately 85 (normal activity with effort, some signs or symptoms of disease), compared with little to no change from a score of around 75 in the control group (103614,112716).
Pregnancy-related pain. It is unclear if oral maritime pine bark extract is beneficial for reducing pain during the third trimester of pregnancy. Details: A small clinical study in patients in the third trimester of pregnancy shows that taking a standardized extract of maritime pine bark (Pycnogenol, Horphag Research) 30 mg daily modestly reduces lower back pain, hip joint pain, pelvic pain, and pain due to varicose veins or calf cramps when compared with a control group (15423).
Psoriasis. It is unclear if oral maritime pine bark extract is beneficial in patients with psoriasis. Details: An observational registry study in adults with moderate to severe plaque psoriasis found that taking a standardized extract of maritime pine bark (Pycnogenol, Horphag Research) 150 mg daily for 12 weeks along with standard treatment is associated with improved quality of life, increased water and moisture content of the skin, reduced plaque severity and total affected body area, and reduced use of corticosteroids when compared with standard treatment alone (97417). However, the validity of these findings is limited by the unblinded, non-randomized nature of the study.
Raynaud syndrome. It is unclear if oral maritime pine bark extract is beneficial in patients with Raynaud syndrome. Details: A small clinical study in females with mild, primary Raynaud syndrome shows that taking a standardized extract of maritime pine bark (Pycnogenol, Horphag Research) 50 mg twice daily for 4 weeks decreases coldness, burning pain, paresthesias, skin color changes, and low temperature areas of the hands when compared with lifestyle changes alone. The lowest finger temperature increased by 30% in those taking this product, compared with 13% in those implementing lifestyle changes alone (103615).
Restless legs syndrome (RLS). It is unclear if oral maritime pine is beneficial for RLS. Details: A small observational study in adults with RLS suggests that taking maritime pine bark extract (Pycnogenol, Horphag Research) 150 mg daily along with standard management (i.e., regular sleep, exercise, vitamin C, B vitamins, proper footwear, and instruction on diet and posture) improves self-reported symptoms associated with RLS when compared to baseline. Maritime pine bark may also be associated with less analgesic use compared with standard management alone (112717). However, the interpretation of these findings, other than analgesic use, is limited by lack of a statistical comparison to the other study group.
Sarcopenia. It is unclear if oral maritime pine bark extract is beneficial in patients with sarcopenia. Details: Observational registry research in adults over 70 years of age with signs of muscle loss has found that taking a standardized extract of maritime pine bark (Pycnogenol, Horphag Research) 150 mg daily along with strength training for 2 months improves hand grip strength, walking distance, total weight lifted, number of steps climbed, and general fitness scores when compared with strength training alone (97404). However, the validity of these findings is limited by the unblinded, non-randomized nature of the study.
Sexual dysfunction. Oral maritime pine bark extract has only been evaluated in combination with other ingredients; its effect when used alone is unclear. Details: A small clinical study in females with sexual dysfunction shows that taking a specific combination tablet (Lady Prelox, Horphag Research) containing a standardized extract of maritime pine bark (Pycnogenol, Horphag Research) 20 mg, L-arginine 200 mg, L-citrulline 200 mg, and a standardized rose hip extract (Rosvita) orally 50 mg daily for 8 weeks, in combination with a management program consisting of lifestyle, diet, exercise, and stress control changes, improves overall sexual function when compared with the management program alone (91963). Taking the same product in a dose of 2 tablets twice daily for 8 weeks, in addition to the lifestyle management program, improves vaginal dryness in pre- and post-menopausal patients when compared with lifestyle management alone (103611). The effect of maritime pine alone on sexual dysfunction is unclear.
Sjogren syndrome. It is unclear if oral maritime pine bark extract is beneficial in patients with Sjogren syndrome. Details: A very small observational study in patients with Sjogren syndrome found that taking a standardized extract of maritime pine bark (Pycnogenol, Horphag Research) 150 mg daily in addition to standard therapy is associated with a reduction in dry eye, dry mouth, and the need for corticosteroids when compared with standard therapy alone (100360).
Systemic lupus erythematosus (SLE). It is unclear if oral maritime pine bark extract is beneficial in patients with SLE. Details: A very small clinical study in adults with SLE shows that taking a standardized extract of maritime pine bark (Pycnogenol, Horphag Research) 120 mg daily for 30 days, followed by 60 mg daily for 30 days, modestly reduces symptoms of SLE in some patients when compared with control (50851).
Traumatic brain injury (TBI). It is unclear if oral maritime pine bark extract is beneficial in patients with TBI. Details: A clinical study in patients admitted to the intensive care unit with TBI shows that administering a standardized maritime pine bark extract (Oligopin, DRT Group) 50 mg three times daily with enteral nutrition for 10 days improves scores on the sequential organ failure assessment (SOFA) and APACHE II [Acute Physiology and Chronic Health Evaluation II], as well as nutritional status, when compared with placebo. At day 28, survival rate was 86% in the treatment group, compared to 71% in the placebo group; however, this difference was not statistically significant (108861).
Urinary tract infections (UTIs). It is unclear if oral maritime pine bark extract is beneficial in patients with recurrent UTIs or interstitial cystitis. Details: An observational registry study in adults aged 30-40 years with a recent history of recurrent UTIs has found that taking a standardized extract of maritime pine bark (Pycnogenol, Horphag Research) 150 mg daily for 2 months is associated with a normal urinalysis in 92% of patients, compared with 68% of those who received no supplementation (108860). Another observational registry study in patients with recurrent UTIs or interstitial cystitis has found that taking this same dose for 2 months is associated with a normal urinalysis in 100% of patients, compared with 35% of patients who took oral cranberry extract 400 mg daily and 36% of those who received no treatment (108859). However, the validity of these findings is limited by the unblinded, non-randomized nature of these studies.
Varicose veins. It is unclear if oral maritime pine bark extract is beneficial in patients with varicose veins. Details: Observational registry research in postpartum adults has found that taking a standardized extract of maritime pine bark (Pycnogenol, Horphag Research) 50 mg daily for 6 months, in addition to using below-knee compression stockings, is associated with reduced edema, leg cramps, total number of varicose veins, and number of visible spider vein clusters when compared with compression stockings alone (97403). However, the validity of these findings is limited by the unblinded, non-randomized nature of the study.
Venous thromboembolism (VTE). While some conflicting evidence exists, low-quality clinical research suggests that oral maritime pine bark extract might prevent superficial thrombosis during flights and reduce the incidence of post-thrombotic syndrome (PTS) in patients with a history of deep vein thrombosis (DVT). Details: Observational registry research has found that a standardized extract of maritime pine bark (Pycnogenol, Horphag Research) 150 mg daily for 10 days is not associated with reduced occurrence of DVT, a type of VTE, when compared with compression stockings or control (97437). However, an older clinical study in patients at moderate or high risk for thrombotic events shows that taking a standardized extract of maritime pine bark (Pycnogenol, Horphag Research) 200 mg 2-3 hours before a flight seems to reduce superficial thrombosis, but not DVT risk, when compared with placebo (50874). Some observational research also has also found that taking standardized maritime pine bark extract (Pycnogenol, Horphag Research) is associated with reduced post-thrombotic syndrome (PTS) and recurrent DVT (100355). Also, some clinical research shows that taking standardized extract of maritime pine bark (Pycnogenol, Horphag Research) daily for one year, while wearing or not wearing compression stockings, reduces the incidence of PTS in patients with a single prior episode of DVT (50925). Maritime bark has also been studied in combination with other natural products. There is some evidence that taking a specific combination product (Flite Tabs, Aidan Products) before a flight and then again 6 hours later might decrease the risk of DVT during long-haul plane flights in high-risk patients. The product combines a blend of 150 mg of standardized extract of maritime pine bark (Pycnogenol, Horphag Research) plus nattokinase (12075).
Wrinkled skin. It is unclear if oral maritime pine bark extract can reduce wrinkles or improve skin health in people with significant sun exposure. Details: A small crossover study in Chinese adults working outdoors shows that taking a standardized extract of maritime pine bark (Pycnogenol, Horphag Research) 50 mg twice daily for 12 weeks improves skin hydration and reduces transepidermal water loss and skin darkening when compared with placebo (105784). More evidence is needed to rate maritime pine for these uses.

PANTOTHENIC ACID (Panthenol)

EFFECTIVE

Pantothenic acid deficiency. Taking pantothenic acid 5-10 mg daily is effective for treating and preventing pantothenic acid deficiency (15).

POSSIBLY INEFFECTIVE

Radiation dermatitis. Topical dexpanthenol does not seem to be beneficial for preventing or treating radiation dermatitis. Details: Applying dexpanthenol, an analog of pantothenic acid, twice daily to areas of irradiated skin does not seem to reduce erythema, desquamation, itching, or pain following radiation treatment (7192). Also, applying dexpanthenol 0.5% cream (Bepanthen, Hoffmann LaRoche ) daily during radiation therapy and for 2 weeks after completing radiation therapy is less effective than methylprednisolone aceponate 0.1% cream (Advantan) at reducing radiation-induced skin irritation (67779).

INSUFFICIENT RELIABLE EVIDENCE to RATE

Acne. Oral or topical pantothenic acid has only been evaluated in combination with other ingredients; its effect when used alone is unclear. Details: In adults with mild to moderate acne, clinical research shows that taking a specific supplement (Pantothen, Avilan Marketing LLC) providing pantothenic acid 1.1 grams twice daily in addition to other B vitamins for 12 weeks modestly reduces total and non-inflammatory lesion counts when compared with placebo (105188). Also, in adolescents or young adults with mild to moderate acne, preliminary clinical research shows that topical application with a gel containing D-panthenol 4%, hydrogen peroxide 4%, and salicylic acid 0.5% once daily for 60 days modestly reduces acne lesions when compared with baseline (105189). The validity of this finding is limited by the lack of a comparator group.
Alcoholism. Although there is interest in using oral pantothenic acid for improving recovery from alcoholism, there is insufficient reliable information about the clinical effects of pantothenic acid for this condition.
Allergic rhinitis (hay fever). Although there is interest in using oral pantothenic acid for allergic rhinitis, there is insufficient reliable information about the clinical effects of pantothenic acid for this condition.
Alopecia areata. Pantothenic acid has only been evaluated in combination with other ingredients; its effect when used alone is unclear. Details: A small clinical study in healthy adults with diffuse hair loss shows that intramuscular administration of dexpanthenol 250 mg and biotin 5 mg once weekly for 6 weeks reduces hair fall count at weeks 1 and 8, but only increases hair density at week 1, when compared to baseline (111366). The validity of these findings is limited by the study's small size, short duration, and lack of comparator group.

Attention deficit-hyperactivity disorder (ADHD). Oral pantothenic acid has only been evaluated in combination with other ingredients; its effect when used alone is unclear. Details: Some small outdated clinical studies in children diagnosed with hyperkinesis suggest that taking calcium pantothenate 1.2 grams, alone or in combination with niacinamide, ascorbic acid, and pyridoxine, does not improve symptoms of hyperactivity when compared with placebo (3351,9957). It is unclear what effects pantothenic may have, if any, in children with a modern diagnosis of ADHD.
Atopic dermatitis (eczema). It is unclear if topical pantothenic acid is beneficial in infants or children with atopic dermatitis. Details: One preliminary clinical trial in infants and children with stable mild atopic dermatitis shows that topical application of an emollient containing panthenol (Bepanthen, SensiDaily, Bayer Consumer Care AG) for 3 months is as effective as a reference emollient for reducing symptoms and preventing a flare. However, the efficacy of the reference emollient (Stelatopia Emollient Cream, Mustela; Laboratoires Expanscience) is unclear based on available preliminary clinical research (105190).
Autism spectrum disorder. Although there is interest in using oral pantothenic acid for autism spectrum disorder, there is insufficient reliable information about the clinical effects of pantothenic acid for this condition.
Carpal tunnel syndrome. Although there is interest in using oral pantothenic acid for carpal tunnel syndrome, there is insufficient reliable information about the clinical effects of pantothenic acid for this condition.
Chronic fatigue syndrome (CFS). Although there is interest in using oral pantothenic acid for CFS, there is insufficient reliable information about the clinical effects of pantothenic acid for this condition.
Conjunctivitis. Although there is interest in using oral or ocular pantothenic acid for conjunctivitis, there is insufficient reliable information about the clinical effects of pantothenic acid for this condition.
Constipation. It is unclear if oral or intramuscular dexpanthenol is beneficial for constipation. Details: Preliminary clinical research shows that administering dexpanthenol (Bepanthene), an analog of pantothenic acid, 400 mg orally or 500 mg intramuscularly daily for 5 days decreases the time to a bowel movement in patients with chronic or occasional constipation when compared with an oral placebo (67822).
Dandruff. Although there is interest in using oral or topical pantothenic acid for dandruff, is insufficient reliable information about the clinical effects of pantothenic acid for this condition.
Depression. Although there is interest in using oral pantothenic acid for depression, there is insufficient reliable information about the clinical effects of pantothenic acid for this condition.

Dry eye. Although there is interest in using ocular pantothenic acid for dry eye, there is insufficient reliable information about the clinical effects of pantothenic acid for this condition.
Dry skin. It is unclear if topical dexpanthenol is beneficial for patients with dry skin. Details: A small, open-label study in healthy adults with dry skin shows that cleansing the skin with a dexpanthenol-containing liquid cleanser (DCLC, Bepanthen SensiControl Daily Gentle Body Wash) daily for 4 weeks increases stratum corneum hydration by 17% without affecting skin barrier function, pH, or microbiome when compared to baseline (111262). The validity of these findings is limited by the lack of blinding and a comparator group.
Epilepsy. Although there is interest in using oral pantothenic acid for epilepsy, there is insufficient reliable information about the clinical effects of pantothenic acid for this condition.
Eye trauma. It is unclear if ocular dexpanthenol is beneficial for eye trauma. Details: Some preliminary clinical research shows that using eyedrops containing dexpanthenol 5%, a derivative of pantothenic acid, two drops four times daily for 28 days following surgery for retinal detachment reduces eye pain and discomfort when compared with placebo drops (67783). However, using a specific dexpanthenol 5% ointment (Bepanthen) does not seem to improve corneal epithelial wound healing following phototherapeutic keratectomy when compared with placebo (67801).
Heart failure. Although there is interest in using oral pantothenic acid for heart failure, there is insufficient reliable information about the clinical effects of pantothenic acid for this condition.
Herpes zoster (shingles). Although there is interest in using oral or topical pantothenic acid for shingles, there is insufficient reliable information about the clinical effects of pantothenic acid for this condition.
Insomnia. Although there is interest in using oral pantothenic acid for insomnia, there is insufficient reliable information about the clinical effects of pantothenic acid for this condition.
Laser skin resurfacing. It is unclear if topical dexpanthenol or pantothenic acid can reduce adverse effects after laser skin resurfacing procedures. Details: A preliminary clinical study shows that use of a dexpanthenol-containing ointment (Bepanthen Wound Healing Ointment, Bayer) once daily modestly reduces the diameter of lesions up to 3 days after fractional carbon dioxide laser resurfacing when compared with petroleum jelly (105743). Also, applying a specific cream (Cicaplast Baume B5 cream, L'Oreal) containing panthenol 5%, madecassoside, copper, zinc, and manganese to one side of the face for 28 days reduces decrustation time by approximately one day when compared with a control emollient. Redness and swelling were lower at 3 days, but there was no difference in pain and burning (105742). It is unclear if these effects are due to pantothenic acid, other ingredients, or the combination.
Multiple sclerosis (MS). Although there is interest in using oral pantothenic acid for MS, there is insufficient reliable information about the clinical effects of pantothenic acid for this condition.
Muscular dystrophy. Although there is interest in using oral pantothenic acid for muscular dystrophy, there is insufficient reliable information about the clinical effects of pantothenic acid for this condition.
Nipple fissures. Although there is interest in using topical pantothenic acid for nipple fissures, there is insufficient reliable information about the clinical effects of pantothenic acid for this condition.
Obesity. Although there is interest in using oral pantothenic acid for obesity, there is insufficient reliable information about the clinical effects of pantothenic acid for this condition.
Pain (chronic). It is unclear if oral or topical pantothenic acid is beneficial for the management of various forms of chronic pain. Details: Although there is interest in using oral or topical pantothenic acid for various forms of chronic pain, including neuropathy and arthritis, there is limited information available about the clinical effects of pantothenic acid for this purpose. One review of preliminary clinical research found that calcium pantothenate does not reduce symptoms of arthritis in patients with rheumatoid arthritis or osteoarthritis (10433).
Parkinson disease. Although there is interest in using oral pantothenic acid for Parkinson disease, there is insufficient reliable information about the clinical effects of pantothenic acid for this condition.
Poison oak and poison ivy dermatitis. Although there is interest in using topical pantothenic acid for poison ivy dermatitis, there is insufficient reliable information about the clinical effects of pantothenic acid for this condition.
Postoperative pain. It is unclear if oral pantothenic acid is beneficial for postoperative pain. Details: In post-tonsillectomy patients aged 5-12 years, preliminary clinical research shows that taking pastilles containing dexpanthenol (Bepanthene, Bayer) 100 mg three times daily reduces pain when compared with placebo. Postoperative pain was modestly reduced at 1, 3, 7, and 14 days after surgery (105191).
Postoperative sore throat. It is unclear if pantothenic acid lozenges are beneficial for postoperative sore throat. Details: Preliminary clinical research shows that taking two lozenges containing dexpanthenol, an analog of pantothenic acid, 200 mg 30 minutes prior to general anesthesia reduces the incidence and severity of postoperative sore throat when compared with a benzydamine hydrochloride or placebo spray (67792).
Pregnancy-related leg cramps. Although there is interest in using oral pantothenic acid for pregnancy-related leg cramps, there is insufficient reliable information about the clinical effects of pantothenic acid for this condition.
Premenstrual syndrome (PMS). Although there is interest in using oral pantothenic acid for PMS, there is insufficient reliable information about the clinical effects of pantothenic acid for this condition.
Respiratory tract infections. Although there is interest in using oral pantothenic acid for respiratory tract infections, there is insufficient reliable information about the clinical effects of pantothenic acid for this condition.
Rhinosinusitis. It is unclear if nasal dexpanthenol is beneficial for rhinosinusitis. Details: Preliminary clinical research shows that using a nasal spray (MarPlus) containing dexpanthenol, an analog of pantothenic acid, on the first, second, fourth, and sixth week after endoscopic sinus surgery reduces nasal discharge, but not other symptoms associated with chronic rhinosinusitis, when compared with saline nasal spray (67808).
Skin irritation. It is unclear if topical dexpanthenol is beneficial for preventing or treating skin irritation due to sodium lauryl sulfate. Details: Preliminary clinical research shows that applying dexpanthenol (Bepanthol Handbalsam), an analog of pantothenic acid, twice daily for 26 days does not prevent sodium lauryl sulfate-induced skin irritation (67785). However, dexpanthenol may be effective for treating skin irritation caused by sodium lauryl sulfate. Use of an ointment containing dexpanthenol 1% to 5% twice daily for up to 30 days following skin exposure to sodium lauryl sulfate seems to reduce skin water loss, skin roughness, and skin inflammation when compared to control (67802,67806).
Ulcerative colitis. Although there is interest in using oral or rectal pantothenic acid for ulcerative colitis, there is insufficient reliable information about the clinical effects of pantothenic acid for this condition.
Vertigo. Although there is interest in using oral pantothenic acid for vertigo, there is insufficient reliable information about the clinical effects of pantothenic acid for this condition.
Wound healing. Preliminary clinical research suggests that oral dexpanthenol might be beneficial for wound healing. Details: In post-tonsillectomy patients aged 5-12 years, preliminary clinical research shows that taking pastilles containing dexpanthenol (Bepanthene, Bayer) 100 mg three times daily improves wound healing when compared with placebo. Depending on the type of surgery, wound healing occurred in 2.3-2.9 times as many patients within 7 days of surgery, and in 13% to 35% more patients within 14 days, when compared with placebo (105191). More evidence is needed to rate pantothenic acid for these uses.

SWEET ORANGE

INSUFFICIENT RELIABLE EVIDENCE to RATE

Asthma. It is unclear if dietary citrus fruits are beneficial in patients with asthma. Details: There is some evidence that consumption of vitamin C-rich citrus fruits, including sweet orange and others, might improve lung function in people with asthma. However, this is controversial. Some studies show that intake of citrus fruits 1-2 times per week produces significant benefit (6049,6055,6056), while other studies have not found this benefit (6057,6058).
Common cold. It is unclear if drinking sweet orange juice prevents the common cold. Details: Preliminary clinical research in healthy individuals ages 17 to 25 years suggests that drinking sweet orange juice 180 mL daily for 72 days might decrease the risk of developing common cold-related symptoms (15328).
Depression. It is unclear if drinking sweet orange juice or using sweet orange essential oil as aromatherapy is beneficial for depression. Details: Preliminary clinical research in adults with depression shows that drinking flavonoid-rich sweet orange juice 190 mL three times daily for 8 weeks modestly improves depression scores when compared to baseline, but not when compared with a low-flavonoid orange drink (110045). Sweet orange has also been studied as part of a combination aromatherapy. A very small clinical study in community-dwelling older adults shows that massage therapy to the upper body with sweet orange, lavender, and bergamot oils twice weekly for 8 weeks improves symptoms of depression in 65% of patients when compared with no intervention. Twice weekly inhalation of the same essential oils via nebulizer, without massage, also improves symptoms of depression in 55% of patients when compared with no intervention (98474).
Hypercholesterolemia. It is unclear if drinking sweet orange juice improves blood lipid levels. Details: A very small clinical study in hypercholesterolemic patients shows that drinking large amounts of sweet orange juice (750 mL daily for four weeks) seems to increase high-density lipoprotein (HDL) cholesterol by 21% and reduce the ratio of low-density lipoprotein (LDL) to HDL cholesterol by 16% when compared to baseline. This effect was not seen with 250-500 mL of sweet orange juice. Because consumption of this large amount of juice daily provides approximately 20% of the daily energy requirement, this regimen may not be practical (3340).
Insomnia. Sweet orange essential oil as aromatherapy has only been evaluated in combination with other essential oils; its effect when used alone is unclear. Details: Preliminary clinical research in adults undergoing hemodialysis shows that inhaling aromatherapy with sweet orange and lavender oil nightly before bed for one month improves overall sleep quality by 72% and fatigue by about 78% when compared with no treatment (98508).
Kidney failure. It is unclear if sweet orange oil massage can improve fatigue or symptoms of restless leg syndrome (RLS) in adults receiving hemodialysis. Details: A small clinical study shows that receiving an 18-minute foot massage with sweet orange oil 1.5% for 3 weeks during hemodialysis sessions modestly improves sleep quality and symptoms of RLS when compared with routine care. However, it does not seem to be more effective than using lavender oil (109859).
Kidney stones (nephrolithiasis). It is unclear if drinking sweet orange juice is beneficial for preventing kidney stones. Details: Consuming 400 mL of sweet orange juice three times a day, providing a total of 100 mEq of citrate daily, increases urinary pH and urinary citrate levels (15171). Theoretically, this might reduce kidney stone formation in patients with calcium nephrolithiasis. However, this outcome has not been evaluated in clinical research.
Obesity. It is unclear if drinking sweet orange juice or taking oral sweet orange extract improves weight loss or other metabolic parameters in adults with overweight or obesity. Most studies suggest that any effects are unlikely to be considered clinically relevant. Details: Some preliminary clinical research in adults with overweight or obesity shows that taking a specific sweet orange extract (Morosil, Bionap S.R.L.) 400 mg orally once daily for six months reduces waist circumference, body weight, fat mass, and body mass index (BMI) by 2% to 5% when compared with placebo (110046). However, other preliminary clinical research in this population shows that drinking red sweet orange juice 750 mL daily for 8 weeks does not reduce body weight or BMI when compared with baseline (92309). A meta-analysis of clinical research in adults, most of whom were overweight or obese at baseline, shows that drinking 250-750 mL of various types of sweet orange juice daily for 2-12 weeks does not reduce body weight, BMI, waist circumference, or body fat percentage (BFP) when compared with control groups, which included either no supplementation, pomegranate juice, or exercise (107853). The validity of this meta-analysis is limited due to the population heterogeneity and variety of orange juice formulations and controls utilized. Some clinical studies have also evaluated sweet orange juice for improving cardiovascular risk factors in overweight and obese adults. Although some research has shown benefit, not all research agrees (110046,110047). A meta-analysis of randomized clinical trials in adults with overweight or obesity shows that drinking sweet orange juice 250-600 mL daily for 2-13 weeks modestly increases high-density lipoprotein cholesterol levels and decrease average systolic blood pressure by 1 mmHg when compared with control. However, drinking sweet orange juice does not affect other blood lipid levels, blood glucose levels, or markers of insulin resistance (110048). The validity of this study is limited by high heterogeneity and a small sample size. In addition, these improvements are unlikely to be considered clinically relevant. Sweet orange extract has also been studied in combination with other ingredients. Some clinical research in overweight adults shows that taking a specific combination product (Sinetrol, Fytexia) 450-700 mg twice daily containing sweet orange, blood orange, and grapefruit extracts for 12 weeks reduces body weight, BFP, and BMI when compared with placebo or baseline (95517,95518). It is unclear if these effects are due to sweet orange, other ingredients, or the combination.
Pre-procedural anxiety. It is unclear if inhaling sweet orange essential oil as aromatherapy reduces anxiety before surgeries or invasive procedures. Details: A small, low-quality study suggests that inhaling the scent from 3 drops of sweet orange essential oil applied to a cotton ball for 5 minutes modesty reduces anxiety and pain scores in patients undergoing needle insertion for hemodialysis when compared with performing a breathing exercise for 3 minutes (105455).
Prostate cancer. It is unclear if drinking sweet orange juice reduces prostate cancer risk. Details: Observational research has found that increasing dietary intake of sweet orange or sweet orange juice is not associated with a reduced risk of developing prostate cancer (15172).
Stress. It is unclear if inhaling sweet orange essential oil as aromatherapy is beneficial for stress. Details: Preliminary clinical research shows that using up to 10 drops of sweet orange essential oil as aromatherapy helps prevent some anxiety and tension associated with stressful tasks when compared with control (90505). More evidence is needed to rate sweet orange for these uses.

Safety view details

Below is general information about the safety of the known ingredients contained in the product Calaguala Fern Leave In Treatment. Some ingredients may not be listed. This information does NOT represent a recommendation for or a test of this specific product as a whole.

ALOE (Aloe Vera)

LIKELY SAFE ...when aloe gel is used topically and appropriately. Aloe gel-containing formulations have been safely applied in clinical trials (101,11982,12096,12098,12159,12160,12163,12164,17418)(90123,90124,90127,90128,90129,90131,97320,98816,103305). When included in topical cosmetics, the Cosmetic Ingredient Review Expert Panel concluded that aloe-derived anthraquinone levels should not exceed 50 ppm (90122).

POSSIBLY SAFE ...when aloe gel is used orally and appropriately, short-term. Aloe gel has been safely used in a dose of 15 mL daily for up to 42 days or 100 mL of a 50% solution twice daily for up to 4 weeks (11984,12164). Also, a specific aloe gel complex (Aloe QDM complex, Univera Inc.) has been safely used at a dose of approximately 600 mg daily for up to 8 weeks (90121). ...when aloe extract is used orally and appropriately, short-term. Aloe extract has been used with apparent safety in a dose of 500 mg daily for one month (101579). Also, an aloe extract enriched in aloe sterols has been used with apparent safety in a dose of 500 mg daily for 12 weeks (101577).

POSSIBLY UNSAFE ...when aloe latex is used orally. There is some evidence that anthraquinones in aloe latex are carcinogenic or promote tumor growth, although data are conflicting (6138,16387,16388,91596,91597). In 2002, the US FDA banned the use of aloe latex in laxative products due to the lack of safety data (8229). ...when aloe whole-leaf extract is used orally. Aloe whole-leaf extract that has not been filtered over charcoal still contains anthraquinones. This type of aloe whole-leaf extract is referred to as being "nondecolorized". The International Agency for Research on Cancer has classified this type of aloe whole-leaf extract as a possible human carcinogen (91598,91908). Although filtering aloe whole-leaf extract over charcoal removes the anthraquinones, some animal research suggests that this filtered extract, which is referred to as being "decolorized", may still cause gene mutations (91598). This suggests that constituents besides anthraquinones may be responsible for the carcinogenicity of aloe whole-leaf extract. It should be noted that commercial products that contain aloe whole-leaf extract may be labeled as containing "whole leaf Aloe vera juice" or "aloe juice" (91908).

LIKELY UNSAFE ...when aloe latex is used orally in high doses. Ingesting aloe latex 1 gram daily for several days can cause nephritis, acute kidney failure, and death (8,8961).

CHILDREN: POSSIBLY SAFE
when aloe gel is used topically and appropriately. Aloe gel-containing formulations have been safely applied in clinical trials (90124,90131).

CHILDREN: POSSIBLY UNSAFE
when aloe latex and aloe whole leaf extracts are used orally in children. Children younger than 12 years may experience abdominal pain, cramps, and diarrhea (4).

PREGNANCY: POSSIBLY UNSAFE
when used orally. Anthraquinones present in aloe latex and aloe whole leaf extracts have irritant, cathartic, and possible mutagenic effects (4,16387,16388,90122). There are also anecdotal reports and evidence from animal research that anthraquinones or aloe whole leaf extracts might induce abortion and stimulate menstruation; avoid using (4,8,19,90122).

LACTATION: POSSIBLY UNSAFE
when aloe preparations are used orally. Cathartic and mutagenic anthraquinones present in aloe latex and aloe whole leaf extracts might pass into milk; avoid using (4,19).

MARITIME PINE (Pine bark extract)

POSSIBLY SAFE ...when used orally and appropriately. A standardized extract of maritime pine bark (Pycnogenol, Horphag Research) has been safely used in doses of 50-450 mg daily for up to one year (2435,2451,2462,2554,2556,7693,10214,10416,12012,14899) (15424,15521,15522,15523,15524,100359,105782). The same extract has also been used with apparent safety in a dose of 800 mg daily for 16 days (103617). A different standardized extract of maritime pine bark (Oligopin, DRT Group) has been used with apparent safety in doses of up to 150 mg daily for up to 12 weeks (105781,105783). ...when applied topically as a cream or powder. A standardized extract of maritime pine bark (Pycnogenol, Horphag Research) 0.5% cream has been used for up to 7 days (50912). Powder from a standardized extract of maritime pine bark (Pycnogenol, Horphag Research) 100 mg has been applied to the skin daily for up to 6 weeks (50887,50896).

CHILDREN: POSSIBLY SAFE
when used orally and appropriately, short-term. A standardized extract of maritime pine bark (Pycnogenol, Horphag Research), administered in a dose of 1 mg/lb body weight daily, has been safely used in a clinical study of children aged 6-18 years for up to 3 months (13120).

PREGNANCY: POSSIBLY SAFE
when used orally during the third trimester of pregnancy. In one small clinical study, a standardized extract of maritime pine bark (Pycnogenol, Horphag Research) has been used at a dose of 30 mg daily with apparent safety during the third trimester of pregnancy (15423). However, more evidence is needed; use cautiously or avoid using.

LACTATION:
There is insufficient reliable information available regarding the safety of maritime pine when used during lactation; avoid using.

PANTOTHENIC ACID (Panthenol)

LIKELY SAFE ...when used orally and appropriately. The pantothenic acid derivative calcium pantothenate has a generally recognized as safe (GRAS) status for use in food products (111258). While a tolerable upper intake level (UL) has not been established, pantothenic has been used in doses of 10-20 grams daily with apparent safety (15,6243,111258) ...when applied topically and appropriately, short-term. The Cosmetic Ingredient Review Expert Panel has concluded that pantothenic acid and its derivatives are safe for use in cosmetic products in concentrations up to 5.3% (111258). Gels or ointments containing a derivative of pantothenic acid, dexpanthenol, at concentrations of up to 5%, have been used safely for up to 30 days (67802,67806,67817).

POSSIBLY SAFE ...when applied intranasally and appropriately, short-term. A dexpanthenol nasal spray has been used with apparent safety up to four times daily for 4 weeks (67826). ...when applied in the eyes appropriately, short-term. Dexpanthenol 5% eyedrops have been used with apparent safety for up to 28 days (67783). ...when injected intramuscularly and appropriately, short-term. Intramuscular injections of dexpanthenol 500 mg daily for up to 5 days or 250 mg weekly for up to 6 weeks have been used with apparent safety (67822,111366).

CHILDREN: LIKELY SAFE
when used orally and appropriately (15,6243). Calcium pantothenate is generally recognized as safe (GRAS) when used as a food additive and in infant formula (111258). However, a tolerable upper intake level (UL) has not been established (15,6243). ...when applied topically and appropriately (67795,105190,111262). Infant products containing pantothenic acid and its derivatives have been used safely in concentrations of up to 5% for infant shampoos and 2.5% for infant lotions and oils. The Cosmetic Ingredient Review Expert Panel has concluded that pantothenic acid and derivatives are safe for use in topical infant products. (111258).

PREGNANCY: LIKELY SAFE

Interactions with Drugs view details

Below is general information about the interactions of the known ingredients contained in the product Calaguala Fern Leave In Treatment. Some ingredients may not be listed. This information does NOT represent a recommendation for or a test of this specific product as a whole.

ALOE (Aloe Vera)

ANTICOAGULANT/ANTIPLATELET DRUGS

Interaction Rating = Moderate Be cautious with this combination.

Severity = High • Occurrence = Possible • Level of Evidence = D

Theoretically, aloe gel might increase the risk of bleeding when taken with anticoagulant or antiplatelet drugs.

Details

In vitro research shows that aloe gel can inhibit platelet aggregation. This inhibition was greater than that seen with celecoxib, but less than that seen with aspirin (105501).

ANTIDIABETES DRUGS

Interaction Rating = Moderate Be cautious with this combination.

Severity = Moderate • Occurrence = Possible • Level of Evidence = D

Aloe might increase the risk of hypoglycemia when taken with antidiabetes drugs.

Details

Preliminary clinical research suggests aloe gel might lower blood glucose levels (11983,12164,19756) and have additive effects when used with antidiabetes drugs. Monitor blood glucose levels closely.

DIGOXIN (Lanoxin)

Interaction Rating = Major Do not take this combination.

Severity = High • Occurrence = Probable • Level of Evidence = D

Theoretically, aloe latex might increase the risk of adverse effects when taken with cardiac glycosides.

Details

Overuse of aloe latex can increase the risk of adverse effects from cardiac glycoside drugs, such as digoxin, due to potassium depletion. Overuse of aloe, along with cardiac glycoside drugs, can increase the risk of toxicity (19).

DIURETIC DRUGS

Interaction Rating = Moderate Be cautious with this combination.

Severity = High • Occurrence = Possible • Level of Evidence = D

Theoretically, aloe latex might increase the risk of hypokalemia when taken with diuretic drugs.

Details

Overuse of aloe latex might compound diuretic-induced potassium loss, increasing the risk of hypokalemia (19).

STIMULANT LAXATIVES

Interaction Rating = Moderate Be cautious with this combination.

Severity = High • Occurrence = Possible • Level of Evidence = D

Theoretically, aloe latex might increase the risk for fluid and electrolyte loss when taken with stimulant laxatives.

Details

Due to cathartic laxative effects of aloe latex, concomitant use with other stimulant laxatives might compound fluid and electrolyte loss (19,19742,19743,19744).

WARFARIN (Coumadin)

Interaction Rating = Moderate Be cautious with this combination.

Severity = High • Occurrence = Possible • Level of Evidence = D

Theoretically, aloe latex might increase the risk of bleeding when taken with warfarin.

Details

Aloe latex has stimulant laxative effects. In some people aloe latex can cause diarrhea. Diarrhea can increase the effects of warfarin, increase international normalized ratio (INR), and increase the risk of bleeding. Advise patients who take warfarin not to take excessive amounts of aloe vera.

MARITIME PINE (Pine bark extract)

ANTICOAGULANT/ANTIPLATELET DRUGS

Interaction Rating = Moderate Be cautious with this combination.

Severity = Moderate • Occurrence = Possible • Level of Evidence = D

Theoretically, maritime pine bark extract might increase the risk of bleeding when used with antiplatelet or anticoagulant drugs.

Details

Clinical research suggests that maritime pine bark extract inhibits platelet aggregation (3283,50844,50942). However, the clinical significance of this effect is unclear.

ANTIDIABETES DRUGS

Interaction Rating = Moderate Be cautious with this combination.

Severity = Moderate • Occurrence = Possible • Level of Evidence = B

Theoretically, maritime pine bark extract might increase the risk of hypoglycemia when used with antidiabetes drugs.

Details

One clinical study shows that maritime pine bark extract decreases blood sugar in patients with diabetes being treated with antidiabetes agents (15522). Monitor blood glucose levels closely. Dose adjustments might be necessary.

IMMUNOSUPPRESSANTS

Interaction Rating = Moderate Be cautious with this combination.

Severity = High • Occurrence = Possible • Level of Evidence = D

Theoretically, maritime pine bark extract might decrease the effectiveness of immunosuppressant therapy.

Details

In vitro and animal research suggests that maritime pine bark extract has immunostimulant activity (2435,2636). This effect has not been reported in humans.

SWEET ORANGE

CELIPROLOL (Celicard)

Interaction Rating = Major Do not take this combination.

Severity = Moderate • Occurrence = Likely • Level of Evidence = B

Consuming sweet orange with celiprolol can decrease oral absorption of celiprolol.

Details

A pharmacokinetic study in healthy volunteers shows that celiprolol levels, after a single dose of 100 mg, are decreased by up to 90% in people who drink sweet orange juice 200 mL three times daily. It's not known if lower consumption of sweet orange juice will have the same effect. Theoretically, this occurs due to short-term inhibition of organic anion transporting polypeptide (OATP) (12115,17603,17604). Recommend separating drug administration and consumption of sweet orange by at least 4 hours (17603,17604).

FEXOFENADINE (Allegra)

Interaction Rating = Moderate Be cautious with this combination.

Severity = Mild • Occurrence = Likely • Level of Evidence = B

Consuming sweet orange juice with fexofenadine can decrease oral absorption of fexofenadine.

Details

Clinical research shows that coadministration of sweet orange juice 1200 mL decreases bioavailability of fexofenadine by about 72% (7046,17604). In an animal model, sweet orange juice decreased bioavailability of fexofenadine by 31% (17605). Fexofenadine manufacturer data indicates that concomitant administration of sweet orange juice and fexofenadine results in larger wheal and flare sizes in research models. This suggests that sweet orange reduces the clinical response to fexofenadine (17603). Theoretically, this occurs due to short-term inhibition of organic anion transporting polypeptide (OATP) (7046). Recommend separating drug administration and consumption of sweet orange by at least 4 hours (17603,17604).

IVERMECTIN (Stromectol, others)

Interaction Rating = Major Do not take this combination.

Severity = Moderate • Occurrence = Likely • Level of Evidence = B

Consuming sweet orange juice with ivermectin can decrease the oral absorption of ivermectin.

Details

A pharmacokinetic study in healthy volunteers shows that taking ivermectin orally with sweet orange juice 750 mL over 4 hours reduces the bioavailability of ivermectin. This effect does not seem to be related to effects on P-glycoprotein. The effect on ivermectin is more pronounced in males compared to females (12154).

ORGANIC ANION-TRANSPORTING POLYPEPTIDE SUBSTRATES (OATP)

Interaction Rating = Major Do not take this combination.

Severity = Moderate • Occurrence = Likely • Level of Evidence = B

Consuming sweet orange juice can decrease oral absorption of OATP substrates. Separate administration by at least 4 hours.

Details

Clinical research shows that consuming sweet orange juice inhibits OATP, which reduces bioavailability of oral drugs that are substrates of OATP (17603,17604). For example, sweet orange juice decreases bioavailability of fexofenadine, a substrate of OATP, by about 72% and of celiprolol, another OATP substrate, by up to 90% (7046,12115). Since sweet orange juice seems to affect OATP for a short time, recommend separating drug administration and consumption of sweet orange juice by at least 4 hours (17603,17604).

P-GLYCOPROTEIN SUBSTRATES

Interaction Rating = Moderate Be cautious with this combination.

Severity = High • Occurrence = Possible • Level of Evidence = B

Sweet orange juice seems to modulate P-glycoprotein (P-gp), which might affect the blood levels of P-gp substrates.

Details

Animal and in vitro research suggest that orange juice extract inhibits drug efflux by P-gp, increasing absorption and levels of P-gp substrates (12116,15327). In contrast, pharmacokinetic research in humans shows that drinking large amounts of sweet orange juice decreases absorption and levels of the P-gp substrate celiprolol. This suggests that orange juice actually induces drug efflux by P-gp or affects drug levels by another mechanism such as inhibiting the gut drug transporter called organic anion transporting polypeptide (OATP) (7046,12115). Until more is known, sweet orange juice should be used cautiously in people taking P-gp substrates.

PRAVASTATIN (Pravachol)

Interaction Rating = Major Do not take this combination.

Severity = Moderate • Occurrence = Likely • Level of Evidence = B

Consuming sweet orange juice with pravastatin can increase the absorption of pravastatin.

Details

A small pharmacokinetic study in healthy volunteers shows that consuming sweet orange juice 800 mL over 3 hours, including before, during, and after taking pravastatin 10 mg, increases pravastatin levels by about 149%, without affecting pravastatin elimination. Theoretically this effect might be due to modulation of organic anion transporting polypeptides (OATPs) by sweet orange juice (14348). Sweet orange juice does not seem to affect simvastatin levels, but it is not known if sweet orange affects any of the other statins.

QUINOLONE ANTIBIOTICS

Interaction Rating = Moderate Be cautious with this combination.

Severity = Moderate • Occurrence = Possible • Level of Evidence = D

Calcium-fortified sweet orange juice might reduce quinolone absorption.

Details

Calcium binds to quinolones in the gut. Theoretically, the calcium in certain fortified orange juices can also bind to quinolone antibiotics and reduce their absorption and levels (4412,10339,13714,21638,38570).

Report an Adverse Reaction to Calaguala Fern Leave In Treatment

Below is general information about the adverse effects of the known ingredients contained in the product Calaguala Fern Leave In Treatment. Some ingredients may not be listed. This information does NOT represent a recommendation for or a test of this specific product as a whole.

ALOE (Aloe Vera)

General ...Orally and topically, aloe products are generally well tolerated when used in typical doses. However, oral aloe latex is associated with a greater risk of adverse effects, especially when used in high doses or long-term.
Most Common Adverse Effects:
Orally: Aloe latex may cause abdominal pain, cramps, and diarrhea.
Topically: Burning, erythema, and itching. Contact dermatitis in sensitive individuals.
Serious Adverse Effects (Rare):
Orally: Aloe latex is associated with serious adverse effects when taken in high doses or long-term. Cases of acute hepatitis due to a hypersensitivity reaction to aloe leaf extract has been reported.

Dermatologic ...Topically, aloe gel has occasionally been associated with burning (12164,19741,30697,30706), itching (12164,19741,30697), eczema (90122), erythema (19748,30706,90123), contact dermatitis (12163,12164,30695,30736,30737,30738,30740), popular eruption (30732), and urticaria (30712). Also, a case of generalized nummular and popular dermatitis attributed to hypersensitivity has been reported for a 47-year-old male who used aloe leaf gel, both topically and orally, for 4 years (30740).

Endocrine ...A case of severe hypokalemia has been reported for a male breast cancer patient who was undergoing chemotherapy and using aloe vera 1 liter daily orally for 2 weeks. The hypokalemia was attributed to the cathartic effects of aloe and resolved once aloe use was discontinued (30704).

Gastrointestinal ...Orally, aloe latex can cause abdominal pain and cramps. Long-term use or abuse of aloe latex can cause diarrhea, sometimes with hypokalemia, albuminuria, hematuria, muscle weakness, weight loss, arrhythmia, and pseudomelanosis coli (pigment spots in intestinal mucosa). Pseudomelanosis coli is believed to be harmless, and usually reverses with discontinuation of aloe. It is not directly associated with an increased risk of developing colorectal adenoma or carcinoma (6138). Orally, aloe gel may cause nausea, stomach cramps, and other gastrointestinal complaints in some patients (104174,111921,111663).
Topically, applying aloe gel in the mouth may cause nausea within 5 minutes of application in some patients (90124).

Hematologic ...A case of Henoch-Schonlein purpura, characterized by abdominal pain, purpura, and severe arthralgia, has been reported in a 52-year-old male who drank aloe juice prepared from four to five leaflets for 10 days prior to symptom development (91598).

Hepatic ...Cases of acute hepatitis have been reported after ingestion of aloe leaf extracts for between 3 weeks and 5 years. This is thought to be a hypersensitivity reaction (15567,15569,16386,17419,90126,91598). A case of acute hepatitis has also been reported for a 45-year-old female who drank two ounces of Euforia juice (Nuverus International), a product containing green tea, noni, goji, and aloe, daily for one month (90125). However, one small clinical trial in healthy individuals shows that taking aloe gel 2 ounces twice daily for 60 days does not impair liver function (104174).

Renal ...Orally, aloe latex can cause hemorrhagic gastritis, nephritis, and acute kidney failure following prolonged use of high doses (1 gram daily or more) (8961).

MARITIME PINE (Pine bark extract)

General ...Orally and topically, maritime pine bark extract seems to be well tolerated.
Most Common Adverse Effects:
Orally: Gastrointestinal complaints, dizziness, and vertigo.

Cardiovascular ...A single case of chest pain has been reported for a patient treated with a standardized extract of maritime pine bark (Pycnogenol, Horphag Research). However, the patient had a history of myocardial infarction (50905). Another patient taking the same maritime pine bark extract experienced acute decompensation of heart failure. The patient previously has stable coronary artery disease (50929). It is not clear if either of these adverse effects were directly related to maritime pine bark extract.

Gastrointestinal ...Orally, a standardized extract of maritime pine bark (Pycnogenol, Horphag Research) may cause gastrointestinal problems (15521,15522,17300,50891,50942). Also, mouth ulcer and bad breath have been reported in a single trial (15521).

Neurologic/CNS ...Orally, a standardized extract of maritime pine bark (Pycnogenol, Horphag Research) may cause dizziness and severe vertigo (15521,15522,17300,50904,50933). Also, headache has been reported in a single trial (15521).
