ALOE

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.

ARTICHOKE (Cynara Scolymus)

POSSIBLY EFFECTIVE

Dyspepsia. Oral artichoke leaf extract may improve symptoms in patients with functional dyspepsia or dyspepsia associated with biliary disease. Details: Several clinical trials in patients with functional dyspepsia or dyspepsia associated with biliary disease show that taking artichoke leaf extract can reduce symptoms such as nausea, vomiting, flatulence, and abdominal pain. Improvement seems to occur after 2 to 8 weeks of treatment (2056,11429,12208). The validity of some of this evidence is limited by a small sample size (2056) or lack of a control group (11429). However, a higher-quality clinical trial in patients with mild dyspepsia shows that taking artichoke leaf extract 640 mg three times daily for 6 weeks improves overall symptom and quality of life scores. Specifically, patient ratings for flatulence, feelings of fullness, and early satiety were reduced when compared with placebo. Further, for every 12 patients treated with this extract over placebo, one additional patient reported markedly or completely improved symptoms (12208). Some studies have used a specific extract called ALE LI 220 (Hepar-SL forte, Serturner Arzneimittel GmbH) at doses ranging from 320-640 mg three times daily for up to 8 weeks (2056,12208). Another study has used a different artichoke leaf extract (Cynara SL, Lichtwer Pharma) at a dose of 320-640 mg daily for 2 months (11429). Some clinical research has also assessed artichoke extract in combination with ginger extract. Results show that taking 2 capsules of a specific product containing artichoke leaf extract 100 mg and ginger extract 20 mg (ProDigest, Indena) daily for 4 weeks markedly or completely improves symptoms such as nausea, fullness, pain, and bloating in about 1.5-fold more patients with functional dyspepsia when compared with placebo (91474).
Hyperlipidemia. Most research shows that oral artichoke lowers cholesterol and triglyceride levels in patients with hyperlipidemia. However, frozen artichoke juice does not appear to have these effects. Details: Multiple meta-analyses and clinical studies in patients who are either healthy or have hyperlipidemia, nonalcoholic fatty liver disease, or pre-obesity show that taking artichoke leaf extract or concentrated artichoke juice capsules daily for 4-24 weeks reduces total cholesterol by 13-18 mg/dL, low-density lipoprotein (LDL) cholesterol by 15-17 mg/dL, and triglycerides by 9-18 mg/dL, but does not increase high-density lipoprotein (HDL) cholesterol, when compared with placebo (104132,108713,111560,111564). While the five studies including non-hyperlipidemic patients in one of these analyses reported mixed results, all four of the studies evaluating artichoke leaf extract in patients with hyperlipidemia showed significant reductions in total cholesterol and LDL cholesterol when compared with placebo (104132). Additionally, a dose-response analysis suggests that baseline cholesterol levels are a stronger predictor of benefit than dose and treatment duration (108713). The validity of these findings is limited due to the high heterogeneity of studies included in meta-analyses. Another clinical study in patients with mild hypercholesterolemia shows that taking artichoke extract 250 mg twice daily for 8 weeks decreases LDL cholesterol by about 11% and increases HDL cholesterol by about 10% when compared with placebo (91478). Other formulations have also been evaluated, including cynarin, a constituent of artichoke, and artichoke juice. Some older, small clinical studies suggest that taking cynarin 20 mg three times daily for 2-7 months reduces total cholesterol and triglyceride levels when compared to baseline in patients with hypercholesterolemia and/or hypertriglyceridemia (52222,52223,52236). However, cynarin does not appear to reduce cholesterol levels in patients with familial type II hyperlipoproteinemia (1424). In patients with hyperlipidemia, consuming frozen artichoke juice 20-30 mL daily for 6-12 weeks does not appear to reduce total or LDL cholesterol levels and may even increase triglyceride levels (52216,52234). Artichoke leaf extract has also been evaluated in combination with other ingredients. Clinical research shows that taking a product containing red yeast rice extract, artichoke leaf extract, and other ingredients (Limicol, Laboratoire Lescuyer) 3 or 6 tablets daily for 4-16 weeks decreases LDL cholesterol by 14% to 21% in patients with hyperlipidemia. However, the red yeast in this product contains monacolin K (lovastatin), which likely contributed to the cholesterol-lowering effect (89451,89452,89454). Another specific product (Vazguard; Indena SpA), containing artichoke leaf extract (Indena SpA) 100 mg and bergamot phytosome 600 mg, has also shown benefit in patients with mild hypercholesterolemia when taken twice daily for 2 months (108712). However, it is unclear if this effect is due to artichoke leaf, bergamot, or the combination.

INSUFFICIENT RELIABLE EVIDENCE to RATE

Biliary disorders. Although there has been interest in using oral artichoke for various biliary disorders, including for the treatment of cholestasis or prevention of gallstones, there is insufficient reliable information about the clinical effects of artichoke for these conditions.
Diabetes. Several small clinical studies suggest that oral artichoke extract may slightly reduce fasting blood glucose, but may not improve glycated hemoglobin (HbA1c) or other measures of glycemic control, in patients with diabetes. Details: A meta-analysis of 9 small clinical trials shows that taking artichoke leaf extract for 8-12 weeks reduces fasting blood glucose by around 5 mg/dL, but does not improve HbA1c, insulin levels, or markers of insulin resistance, when compared with placebo (105768). The generalizability of these findings to patients with diabetes is limited; only 2 of the 9 studies specifically enrolled patients with diabetes. The other studies included patients who were overweight or with liver disease, hyperlipidemia, or metabolic syndrome. In contrast, a post-hoc analysis of clinical research in overweight adults at risk for developing diabetes shows that taking a specific artichoke leaf product (Altilix, Bionap S.r.l.) 50 mg daily for 6 months reduces HbA1c by around 0.9% and improves measures of insulin resistance and beta-cell function when compared with placebo (111564).
Hangover. It is unclear if oral artichoke extract is beneficial for the prevention of hangover. Details: A small clinical study in healthy adults shows that taking artichoke extract 960 mg immediately before and after alcohol consumption does not prevent alcohol-induced hangover when compared with placebo (11774).
Hepatitis C. It is unclear if oral artichoke is beneficial in patients with hepatitis C. Details: One small clinical study in patients with chronic hepatitis C shows that taking artichoke leaf extract 3200 mg daily for 12 weeks does not normalize liver enzyme levels or reduce viral load when compared to baseline. Although symptoms such as fatigue, abdominal discomfort, and joint problems appear to improve in the first 4 weeks, the improvement is not maintained over 12 weeks (91475). However, another small clinical study shows that drinking a tea infusion of wild artichoke three times daily for 3 months normalizes liver enzymes and serum virus levels in 12 of 15 patients with hepatitis C (97717). The validity of these findings is limited by the lack of a control group.
Hypertension. Analyses of small clinical studies suggest that oral artichoke may slightly reduce blood pressure in patients with hypertension; however, individual study results are conflicting, and the improvements in blood pressure may not be clinically significant. Details: Evidence regarding an association between artichoke consumption and hypertension is conflicting (91477,104133,105767,111561). Two meta-analyses include many of the same studies yet reach contradictory conclusions. One meta-analysis of 8 small clinical trials shows that taking artichoke leaf extract, powder, or juice for 8-12 weeks does not reduce systolic blood pressure (SBP) or diastolic blood pressure (DBP). However, subgroup analysis in patients with documented hypertension shows that artichoke reduces SBP by around 3 mmHg and DBP by around 2 mmHg when compared with placebo (105767). In contrast, another meta-analysis of 7 small clinical trials shows that taking artichoke 50-2700 mg daily for 4-12 weeks reduces SBP by about 2 mmHg and DBP by about 1.5 mmHg. Subgroup analysis shows that the greatest reductions in SBP and DBP occur in doses of 500 mg daily or less, at durations longer than 8 weeks, and in patients under 50 years old (111561). Discrepancies between the results of the meta-analyses with overlapping studies may be due to the former meta-analysis including artichoke supplementation in combination with other ingredients, while the latter meta-analysis focused on artichoke supplementation alone.
Irritable bowel syndrome (IBS). It is unclear if oral artichoke leaf extract is beneficial in patients with IBS. Details: Some observational research in patients with IBS has found that taking a specific artichoke leaf extract (Hepar-SL forte, Serturner Arzneimittel GmbH) 640 mg three times daily for 6 weeks is associated with reductions in abdominal pain, cramping, bloating, flatulence, and constipation when compared to baseline (2562). Also, a small clinical study in patients with IBS shows that taking a different specific artichoke leaf extract (Cynara SL, Lichtwer Pharma) 320-640 mg daily for 2 months reduces the incidence of IBS symptoms in patients with dyspepsia by about 26% when compared to baseline. Patients taking this extract also had improved quality of life (15204). The validity of these findings is limited by the lack of a control group.
Metabolic syndrome. It is unclear if oral artichoke leaf extract is beneficial in patients with metabolic syndrome. Details: A small clinical trial in patients with metabolic syndrome shows that taking artichoke leaf extract 1800 mg daily for 12 weeks does not improve fasting blood glucose, insulin resistance, total cholesterol, low-density lipoprotein (LDL) cholesterol, high-density lipoprotein (HDL) cholesterol, or blood pressure when compared with placebo. However, taking artichoke extract does reduce triglycerides by around 27 mg/dL when compared with placebo (100935).
Nausea and vomiting. Although there has been interest in using oral artichoke for nausea and vomiting, there is insufficient reliable information about the clinical effects of artichoke for this purpose.
Nonalcoholic fatty liver disease (NAFLD). It is unclear if oral artichoke leaf extract is beneficial in patients with NAFLD. Details: Meta-analyses of 12 clinical studies in adults with a variety of metabolic disorders, including NAFLD, show that taking artichoke 50-2700 mg daily for 4-24 weeks reduces alanine aminotransferase (ALT) and aspartate aminotransferase (AST) when compared with placebo (111560,111563). These effects are greater for ALT in trials lasting 8 weeks or longer and for AST at doses over 500 mg daily (111563). The validity of these findings is limited by significant heterogeneity among the included studies. A small clinical trial in patients with NAFLD shows that taking a specific artichoke leaf extract (Cynarol, Niak Pharmaceuticals), standardized to contain cynarin 2%, as 200 mg three times daily for 2 months improves NAFLD severity, reduces liver size, and increases hepatic vein flow when compared with placebo. The severity of NAFLD improved in 82% of patients taking artichoke, compared with 5% taking placebo. NAFLD severity did not worsen in any patients taking artichoke, compared with 27.5% of those taking placebo. Serum levels of liver transaminases, total bilirubin, and lipids were also improved with artichoke when compared with placebo (100934). However, the validity of these findings is limited by inappropriate randomization, the use of a per-protocol analysis, and significant differences between groups at baseline. Artichoke leaf extract has also been evaluated in combination with conventional therapies. A clinical trial shows that taking metformin 500 mg twice daily and/or vitamin E 400 IU once daily along with a specific artichoke leaf extract (Tishoke; Goldaru Company) 400 mg twice daily, providing 40 mg chlorogenic acid daily, for 12 weeks improves NAFLD severity and reduces liver size when compared with baseline. However, these improvements were similar to those seen in patients taking metformin with vitamin E. After 12 weeks, the number of patients with no fat accumulation (steatosis grade 0) increased by 23% in the artichoke and metformin group, 17% in the artichoke and vitamin E group, and 10% in the metformin and vitamin E group (108714)
Obesity. A meta-analysis of several small clinical studies suggests that oral artichoke extract may slightly reduce waist circumference, but not body weight or body mass index (BMI), in patients who are overweight or obese. Details: A meta-analysis of 10 small clinical trials shows that taking artichoke leaf extract, powder, or juice for 8-12 weeks reduces waist circumference by 1.11 cm, but does not improve body weight or BMI, when compared with placebo (105766). The generalizability of these findings to patients who are overweight or obese is limited by the fact that only 3 of the 10 trials specifically enrolled patients because they were overweight. Other studies evaluated patients with liver disease, metabolic syndrome, diabetes, hyperlipidemia, or hypertension. In contrast, a post-hoc analysis of clinical research in adults with overweight shows that taking an artichoke leaf supplement (Altilix, Bionap S.r.l.) 150 mg daily for 6 months reduces body weight by around 2.3 kg but does not improve waist circumference when compared with placebo (111564).
Osteoarthritis. Although there has been interest in using oral artichoke for osteoarthritis, there is insufficient reliable information about the clinical effects of artichoke for this purpose. More evidence is needed to rate artichoke for these uses.

GREAT PLANTAIN (Plantago major)

INSUFFICIENT RELIABLE EVIDENCE to RATE

Burns. It is unclear if topical great plantain is beneficial for burns. Details: A very small clinical study in hospitalized adults with bilateral second degree burns shows that applying great plantain extract 10% ointment to burns on one side of the body is similarly effective to applying silver sulfadiazine 1% ointment daily to burns on the other side of the body in relation to healing time, pain intensity, and rate of wound infections (110088). Due to its small size, this study may have been inadequately powered to detect a difference between groups.
Cough. Oral great plantain has only been evaluated in combination with other ingredients; its effect when used alone is unclear. Details: A small study in children 3-6 years of age with acute cough shows that taking a specific syrup (KalobaTUSS, Schwabe Pharma Italia Srl) based on acacia honey with extracts of great plantain, elecampane, mallow, and sandy everlasting, as 5 mL four times daily for 8 days, produces rapid and sustained reductions in both nighttime and daytime cough scores when compared with placebo (105734). It is unclear if these findings are due to great plantain, other ingredients, or the combination.
Diabetic foot ulcers. It is unclear if topical great plantain is beneficial for diabetic foot ulcers. Details: A small unblinded clinical study in hospitalized adults in Iran with Wagner's stage 1 or 2 diabetic foot ulcers or stage 2 or 3 pressure ulcers based on the National Pressure Injury Advisory Panel system shows that applying great plantain extract 10% gel for 14 days reduces wound size and erythema when compared to treatment with various standard wound dressings. Complete wound healing may also occur more frequently at 2 weeks with topical great plantain extract (110090). Poor study methodology and a lack of sub-analysis by ulcer type limits the reliability of these findings. Another small clinical study in patients with a Wagner's stage 1 or 2 diabetic foot ulcer receiving oral antibiotics shows that applying a topical product containing great plantain and aloe twice daily for 4 weeks reduces ulcer surface area and healing time when compared with antibiotics alone. However, the combination product has no effect on ulcer depth (97323). It is unclear if these findings are due to great plantain, aloe, or the combination.
Menorrhagia. It is unclear if oral great plantain leaf extract is beneficial in patients with menorrhagia. Details: A small clinical trial in adults with abnormal uterine bleeding shows that taking a syrup containing great plantain leaf 12% extract 3 times a day for the first 5 days of menstruation and repeating over 3 cycles reduces bleeding severity, but not bleeding duration, similarly to mefenamic acid 250 mg taken every 8 hours (104214).
Nonalcoholic fatty liver disease (NAFLD). It is unclear if oral great plantain seed is beneficial in patients with NAFLD. Details: One small clinical trial in patients with NAFLD shows that taking great plantain seed 1000 mg twice daily for 12 weeks improves fatty liver grade on ultrasound and reduces levels of alanine aminotransferase (ALT), aspartate aminotransferase (AST), and triglycerides when compared with placebo (106645).
Obesity. It is unclear if oral great plantain leaf is beneficial in patients with obesity. Details: One small clinical trial in females with obesity shows that taking powdered great plantain leaf 400 mg daily for 12 weeks does not reduce body weight or body mass index when compared with placebo (106642).
Oral mucositis. Small clinical studies suggest that oral great plantain extract might reduce the severity of oral mucositis, but rinsing with great plantain solution does not seem to be superior to sodium bicarbonate or chlorhexidine for improving healing time. Details: A small clinical study in adults undergoing radiation therapy for head and neck cancer shows that taking a syrup containing great plantain extract 7.5 mL three times daily for 7 weeks reduces the severity of oral mucositis when compared with placebo. Patients taking great plantain syrup also reported lower pain scores as measured on a visual analogue scale when compared with those taking placebo (104213). However, a small clinical trial in cancer patients with oral mucositis shows that there is no difference in the healing time of lesions for patients rinsing with either sodium bicarbonate 5%, great plantain 5%, or chlorhexidine 0.12% solutions. All three solutions were used as a rinse for 2 minutes every 6 hours for up to 2 weeks (98209).
Pressure ulcers. It is unclear if topical great plantain is beneficial in patients with pressure ulcers. Details: One small clinical trial in patients with pressure ulcers being treated with topical phenytoin cream shows that application of great plantain 10% cream 12 hours after application of phenytoin daily for 2 weeks improves healing rate when compared with phenytoin and placebo (106643). Another small, unblinded clinical study in hospitalized adults in Iran with stage 2 or 3 pressure ulcers based on the National Pressure Injury Advisory Panel system or Wagner's stage 1 or 2 diabetic foot ulcers shows that applying great plantain extract 10% gel for 14 days reduces wound size and erythema when compared to a treatment with various standard wound dressings. Complete wound healing may also occur more frequently at 2 weeks with topical great plantain extract (110090). Poor study methodology and a lack of sub-analysis by ulcer type limits the reliability of these findings.
Ulcerative colitis. It is unclear if oral great plantain seed is beneficial in patients with ulcerative colitis. Details: One small clinical trial in patients with ulcerative colitis shows that taking roasted great plantain seed 1200 mg three times daily for 8 weeks reduces abdominal tenderness, gastroesophageal reflux, and gastric pain when compared with placebo (106644). More evidence is needed to rate great plantain for these uses.

LACTICASEIBACILLUS CASEI (Lactobacillus casei)

INSUFFICIENT RELIABLE EVIDENCE to RATE

Antibiotic-associated diarrhea. Oral Lacticaseibacillus casei has only been evaluated in combination with other ingredients; its effect when used alone is unclear. Details: Clinical research shows that taking a specific L. casei-containing combination product (Bio-K+ CI1285) may be beneficial for preventing antibiotic-associated diarrhea. This combination product provides L. casei LBC80R, Lactobacillus acidophilus CL1285 and Lacticaseibacillus rhamnosus CLR2 as 100 billion colony-forming units (CFUs) daily (25494,95402,95403) However, taking L. casei might not help with the treatment of antibiotic-associated diarrhea. Clinical research in hospitalized patients with antibiotic-associated diarrhea shows that taking a combination of L. casei 20 million CFUs and Bifidobacterium breve 50 million CFUs 3 times daily does not reduce the average duration of diarrhea, the frequency of healing, or relapse rates, when compared with taking placebo (111006).
Atopic dermatitis (eczema). Oral Lacticaseibacillus casei has only been evaluated in combination with other ingredients; its effect when used alone is unclear. Details: In children under two years of age with atopic dermatitis who are on a cow's milk protein elimination diet, clinical research shows that taking a specific mixture (Latopic, Biomed S.A.) providing 1 billion colony-forming units (CFUs) of L. casei ôOCK 0919 50%, Lacticaseibacillus rhamnosus ŁOCK 0900 25%, and L. rhamnosus ôOCK 0908 25% for 3 months increases the odds of a 30% or greater improvement in symptom scores by about 2.6-fold when compared with placebo. However, there was no difference in the absolute symptom scores between groups. Beneficial effects of this combination were greater in children confirmed to have allergen sensitization (107510). Other clinical research in children ages 4-17 years shows that taking 1 billion CFUs of a 1:1:1 combination of L. casei CECT 9104, Bifidobacterium lactis CECT 8145, and Bifidobacterium longum CECT 7347 for 12 weeks modestly reduces symptom severity and the need for topical corticosteroids when compared with placebo (107531).
Cancer. Although there has been interest in using oral Lacticaseibacillus casei for cancer prevention or treatment, there is insufficient reliable information about the clinical effects of L. casei for this condition.
Clostridioides difficile infection. Some early research suggests that oral Lacticaseibacillus casei may be beneficial for preventing a first C. difficile infection. However, the quality of evidence is generally poor, and taking oral L. casei does not seem to be beneficial for the prevention of C. difficile recurrence. Details: Evidence from clinical and observational research investigating the effect of L. casei on C. difficile occurrence or recurrence is weak. Most studies use this species in combination with one or more additional probiotic species, including a specific product (Bio-K+ Cl1285) providing L. casei LBC80R and Lactobacillus acidophilus CL1285 and a specific product (Bio-K+ 50 Billion; Bio-K Plus International) providing L. casei LBC80R, L. acidophilus CL1285, and Lacticaseibacillus rhamnosus CLR2 as 50 or 100 billion CFUs daily (25494,90231,90934,95369,95403,107529). Observational research has found that providing a specific combination (Bio-K+ 50 Billion; Bio-K Plus International) of L. casei LBC80R, L. rhamnosus CLR2, and L. acidophilus CL1285 as 50-100 billion colony-forming units (CFUs) daily for 5 days to patients who are on antibiotics for at least 2 days reduces the hospital-wide incidence of C. difficile by approximately 40%. The incidence rate was decreased by at least 50% in the highest risk individuals taking this combination (107529). Current guidelines from the Infectious Diseases Society of America (IDSA) state that there is insufficient information to recommend administration of probiotics for the primary prevention of C. difficile-associated diarrhea (107538).
Constipation. Oral Lacticaseibacillus casei has only been evaluated in combination with other ingredients; its effect when used alone is unclear. Details: Combinations of probiotics containing L. casei appear to increase stool frequency and improve symptoms of functional constipation in adults. These combinations include Hexbio, containing L. casei, Lactobacillus acidophilus, Lactobacillus delbrueckii subsp. lactis, Bifidobacterium bifidum, Bifidobacterium longum, and Bifidobacterium longum subsp. infantis 30 billion CFUs twice daily for 7 days (90266), and ID-HWS1000, containing L. casei IDCC 3451, Lactiplantibacillus plantarum IDCC 3501, Lacticaseibacillus rhamnosus IDCC 3201, Bifidobacterium animalis subsp. lactis IDCC 4301, Bifidobacterium breve IDCC 4401, Lactococcus lactis IDCC 2301, xylooligosaccharide, and dietary fiber as nondigestible maltodextrin, oat fiber, and psyllium husk fiber (107517).
Depression. Oral Lacticaseibacillus casei has only been evaluated in combination with other ingredients; its effect when used alone is unclear. Details: A small clinical study in patients with major depression shows that taking L. casei, Lactobacillus acidophilus, and Bifidobacterium bifidum daily for 8 weeks reduces symptoms of depression measured on the Beck Depression Inventory (BDI) when compared with placebo (99780). However, the validity of the results from this study is limited by incomplete reporting. For example, patient baseline BDI scores were not reported.
Diabetes. It is unclear if oral Lacticaseibacillus casei is beneficial for treatment of type 2 or gestational diabetes. Details: In patients with gestational diabetes, clinical research shows that taking a combination of freeze-dried L. casei, Lactobacillus acidophilus, and Bifidobacterium bifidum each as 2 billion colony-forming units (CFUs) per gram daily for 6 weeks improves fasting blood glucose levels and glycemic control when compared with placebo (95416,98430). Furthermore, a sub-analysis of a meta-analysis of clinical research investigating the effects of L. casei as part of multi-ingredient probiotic and prebiotic products shows that taking products containing L. casei modestly reduces fasting insulin levels and improves insulin resistance in this population. There were also modest reductions in triglyceride levels; however, the effects on fasting blood glucose were not significant (111796). It is unclear from these studies if any beneficial effects are related to L. casei, L. acidophilus, Bifidobacterium bifidum, or the combination. Limited evidence from mainly small clinical trials has also assessed the effects of L. casei for type 2 diabetes. In one study, taking L. casei 100 million CFUs daily for 8 weeks reduces fasting blood glucose by about 28 mg/dL when compared with placebo. There was no effect on glycated hemoglobin; however, the duration was inadequate to demonstrate an effect (99786). In another study, taking a specific product (Familact) containing L. casei and six other probiotic strains daily for 6 weeks reduces fasting blood glucose, but does not affect plasma insulin, when compared with placebo (99790).
Diarrhea. Oral Lacticaseibacillus casei has only been evaluated in combination with other ingredients; its effect when used alone is unclear. Details: A small clinical study in children with dysentery being treated with ceftriaxone shows that taking a specific combination probiotic sachet (Kidilact, Zisttakhmir Company) containing L. casei, Lactobacillus acidophilus, Lacticaseibacillus rhamnosus, Lactobacillus delbrueckii subsp. bulgaricus, Bifidobacterium longum subsp. infantis, Bifidobacterium breve, and Streptococcus thermophilus daily for 5 days modestly reduces the duration of diarrhea, hospitalization, and blood in diarrhea when compared with control (102417). Although The European Society for Pediatric Infectious Diseases recommends probiotics in hospitalized children with diarrhea (98469) and the Infectious Disease Society of America (IDSA) recommends probiotics for the outpatient treatment of acute diarrhea (95388), both guidelines note that most evidence is low quality.
Helicobacter pylori. It is unclear if oral Lacticaseibacillus casei is beneficial for H. pylori eradication in adults or children. Details: Clinical research in adults shows that taking L. casei along with six other probiotics in conjunction with bismuth quadruple therapy does not seem to improve H. pylori eradication rates when compared with placebo and bismuth quadruple therapy (90291). Also, taking a combination of L. casei and Lactobacillus acidophilus without any standard H. pylori therapies does not improve H. pylori eradication rates (12766). However, a clinical study in children shows that taking a fermented milk product containing L. casei DN-114 001 for 14 days along with triple therapy comprised of omeprazole, amoxicillin, and clarithromycin for 7 days improves the H. pylori eradication rate to approximately 85%, compared with 61% of those given triple therapy alone (107544).
HIV/AIDS. Although there has been interest in using oral Lacticaseibacillus casei for HIV/AIDS, there is insufficient reliable information about the clinical effects of lactobacillus for this condition.
Hyperlipidemia. It is unclear if oral Lacticaseibacillus casei is beneficial for hyperlipidemia. Details: In patients with primary hyperlipidemia, clinical research shows that taking L. casei 200 million colony-forming units in combination with red yeast rice twice daily for 8 weeks does not have beneficial effects on low-density lipoprotein (LDL) cholesterol, high-density lipoprotein (HDL) cholesterol, or triglyceride levels, when compared with taking red yeast rice alone. Taking L. casei seems to modestly reduce diastolic blood pressure in this population; however, it is unclear if these changes are clinically significant (112517).
Hypertension. It is unclear if oral Lacticaseibacillus casei is beneficial for lowering blood pressure. Details: A meta-analysis of 18 clinical trials shows that taking various species of lactobacilli as 100 million to 1.5 trillion colony-forming units daily for 3-24 weeks reduces systolic and diastolic blood pressure by 3 mmHg and 1.5 mmHg, respectively, when compared with placebo in various populations. However, sub-group analyses of three clinical trials show that these benefits do not occur in clinical research investigating the effects of L. casei, specifically (105135).
Irritable bowel syndrome (IBS). Oral Lacticaseibacillus casei has only been evaluated in combination with other ingredients; its effect when used alone is unclear. Details: A clinical study in patients with diarrhea-predominant IBS shows that taking a specific multi-species probiotic (NordBiotic, MBM Biotix) containing L. casei LC130, Lacticaseibacillus rhamnosus LR110, Lacticaseibacillus paracasei LPC100, Lactobacillus acidophilus LA120, Lactiplantibacillus plantarum LP140, Bifidobacterium breve BB010, Bifidobacterium longum BL020, Bifidobacterium bifidum BF030, Bifidobacterium animalis subsp. lactis BL040, and Streptococcus thermophilus ST250 as 2.5 billion colony-forming units (CFUs) total twice daily for 8 weeks improves overall symptom severity, as well as pain severity, pain frequency, and quality of life, when compared with placebo. Symptom severity was rated as mild by approximately 60% of those taking the probiotic mixture, compared with 30% of those taking placebo (107516). However, clinical research shows that taking another multi-species combination of L. casei LBC80R, L. acidophilus CL1285, and L. rhamnosus CLR2 50 billion CFUs each daily for 3 months does not improve symptoms in patients with IBS when compared with placebo (99789).
Lyme disease. Although there has been interest in using oral Lacticaseibacillus casei for Lyme disease, there is insufficient reliable information about the clinical effects of lactobacillus for this condition.
Necrotizing enterocolitis (NEC). It is unclear if oral Lacticaseibacillus casei is beneficial or safe for NEC prevention. Details: Most meta-analyses of clinical research show that giving lactobacilli enterally reduces the risk of NEC and/or severe NEC in preterm, mainly very low birth weight (VLBW), infants. Some meta-analyses support the use of lactobacilli in combination with bifidobacteria, as opposed to lactobacilli alone for reducing the risk of NEC. However, the effects of L. casei specifically are unclear (95344,95351,103437,103445,104157,105162,105164). Also, guidance among regulatory agencies and clinical organizations varies with respect to the use of probiotics in very low birth weight infants under 1000 grams. The US Food and Drug Administration (FDA) warns that preterm infants given probiotics are at risk of serious infections caused by the bacteria or fungi contained in probiotics due to cases reported in this group of infants (111610). Also, The American Academy of Pediatrics does not support the routine administration of probiotics to preterm infants, particularly those with a birth weight below 1000 grams, due to conflicting data on safety and efficacy and potential for harm in this vulnerable population (111608). The Canadian Paediatric Society, the American Gastroenterological Association, and the European Society for Paediatric Gastroenterology, Hepatology and Nutrition state that probiotic combinations may be of benefit in reducing the incidence of NEC in preterm neonates over 1000 grams. However, L. casei is not specifically recommended (103003,111609,111611).
Nonalcoholic fatty liver disease (NAFLD). Oral Lacticaseibacillus casei has only been evaluated in combination with other ingredients; its effect when used alone is unclear. Details: A small clinical trial in adults with NAFLD shows that taking a combination of L. casei BCMC 12,313, Lactobacillus acidophilus BCMC 12,130, Lactobacillus delbrueckii subsp. lactis BCMC 12,451, Bifidobacterium bifidum BCMC 02290, Bifidobacterium longum subsp. infantis BCMC 02129, and Bifidobacterium longum BCMC 02120 as 30 billion colony-forming units twice daily for 6 months has no beneficial effects on hepatic steatosis or fibrosis or on levels of liver enzymes, blood lipids, or fasting blood glucose, when compared with placebo (107523).
Polycystic ovary syndrome (PCOS). Oral Lacticaseibacillus casei has only been evaluated in combination with other ingredients; its effect when used alone is unclear. Details: In patients with PCOS, clinical research shows that taking a combination of L. casei T2 (IBRC-M10783), Lactobacillus acidophilus T16 (IBRC-M10785), and Bifidobacterium bifidum T1 (IBRC-M10771) as 2 billion colony-forming units (CFUs) each, plus inulin 800 mg, daily for 12 weeks modestly reduces serum insulin and triglyceride levels and improves insulin resistance and insulin sensitivity when compared with placebo. However, it does not alter cholesterol or fasting blood glucose levels (105159). Clinical research also shows that 31.3% of patients with PCOS taking L. casei in combination with other probiotics daily for 6 months had regular menstrual cycles compared with 12.5% of those taking placebo. There were also modest improvements in testosterone levels and waist circumference, but not other hormones, insulin resistance, body weight, or most measures of quality of life. The product provided L. casei UBLC-42 1 billion CFUs, along with Lactiplantibacillus plantarum UBLP-40, Lactobacillus acidophilus UBLA-34, Lacticaseibacillus casei UBLC-42, Limosilactobacillus fermentum UBLF-31, Lacticaseibacillus rhamnosus UBLR-58, Limosilactobacillus reuteri UBLRu-87, Bifidobacterium bifidum UBBB-55, and fructo-oligosaccharides (FOS) daily for 2 months and then twice daily for 4 months. All patients also underwent dietary and lifestyle changes (110974).
Pregnancy-induced nausea and vomiting. Oral Lacticaseibacillus casei has only been evaluated in combination with other ingredients; its effect when used alone is unclear. Details: A small preliminary clinical trial shows that taking probiotics during pregnancy reduces the severity and duration of nausea and vomiting by 16% to 54%. There was also a small benefit on stool hardness. A specific probiotic (Probiotics 10, Nature's Bounty) was taken as 2 capsules daily for two back-to-back cycles comprised of six days with probiotics and two days without. Each capsule contained a total of 10 billion colony-forming units (CFUs) of L. casei Lc-11, Lactiplantibacillus plantarum 299v and DSM 15312, Lactobacillus delbrueckii subsp. bulgaricus Lb-87, Lacticaseibacillus paracasei DSM 13434 and Lpc-37, Ligilactobacillus salivarius Ls-33, Levilactobacillus brevis Lbr-35, Lactobacillus acidophilus La-14, and Bifidobacterium animalis subsp. lactis Bl-04, along with inulin 200 mg (107199).
Rheumatoid arthritis (RA). Small clinical studies suggest that taking Lacticaseibacillus casei might be beneficial for RA. Details: Two small clinical studies in patients with RA show that taking L. casei 01 as 100 million colony-forming units daily for 8 weeks reduces tender and swollen joints and increases the number of patients who experience moderate symptom improvement when compared with placebo (90230,90297). However, one small clinical study in patients with moderate-to-severe RA shows that taking capsules containing freeze-dried strains of L. casei, Lactobacillus acidophilus, and Bifidobacterium bifidum daily for 8 weeks does not reduce RA severity, the number of tender or swollen joints, or joint pain when compared with placebo (95418).
Rotaviral diarrhea. It is unclear if Lacticaseibacillus casei is beneficial for rotaviral diarrhea. Details: Although the World Gastroenterology Organization has not made a recommendation (98471), the European Society for Pediatric Infectious Diseases recommends probiotics in hospitalized children with diarrhea (98469) and the Infectious Disease Society of America (IDSA) recommends probiotics for the outpatient treatment of acute diarrhea (95388). However, these guidelines note that most evidence is low quality and is not specific to rotavirus infection. Furthermore, these guidelines were released prior to the publication of the most recent, high-quality studies showing no benefit with the use of certain probiotics (98427,98428). Research on the use of L. casei, specifically, for this purpose is lacking.
Short bowel syndrome. Although there has been interest in using oral Lacticaseibacillus casei for short bowel syndrome, there is insufficient reliable information about the clinical effects of L. casei for this condition.
Small intestinal bacterial overgrowth (SIBO). It is unclear if oral Lacticaseibacillus casei is beneficial for the treatment of SIBO. Details: A small clinical study in children with chronic diarrhea due to SIBO shows that taking a combination of lyophilized L. casei 1.5 grams and Lactobacillus acidophilus 1.5 grams by mouth twice daily for 21 days decreases average daily stools by 1.5, but does not improve other symptoms, when compared with placebo (91143). Disparate study findings may be due to many factors, including differences in patient populations evaluated and use of different probiotic formulations. More evidence is needed to rate Lacticaseibacillus casei for these uses.

Safety view details

Below is general information about the safety of the known ingredients contained in the product Vp 30. 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

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).

ARTICHOKE (Cynara Scolymus)

LIKELY SAFE ...when used orally in amounts commonly found in foods. Artichoke has Generally Recognized As Safe status (GRAS) for use in foods in the US (4912).

POSSIBLY SAFE ...when used orally and appropriately in medicinal amounts. Artichoke extract has been used with apparent safety at doses up to 3200 mg daily for up to 12 weeks (6282,15204,52235,91475,91478,100934). Artichoke leaf powder has been used with apparent safety at a dose of 1000 mg daily for up to 8 weeks (104133). Cynarin, a constituent in artichoke extract, has been used with apparent safety at daily doses of 750 mg daily for up to 3 months or 60 mg daily for up to 7 months (1423,1424,52222,52223,52236).

PREGNANCY AND LACTATION:
There is insufficient reliable information available about the safety of artichoke when used in medicinal amounts during pregnancy or lactation; avoid amounts greater than those found in foods.

GREAT PLANTAIN (Plantago major)

POSSIBLY SAFE ...when great plantain seed is used orally, short-term. Great plantain seed has been used with apparent safety at doses up to 3600 mg daily for up to 8 weeks and 2000 mg daily for up to 12 weeks (106644,106645). ...when used topically, short-term. Topical great plantain 10% has been used with apparent safety for up to 2 weeks (106643,110088,110090). There is insufficient reliable information available about the safety of great plantain leaf or leaf extract when used orally.

PREGNANCY: LIKELY UNSAFE
when used orally because it can increase uterine tone (4).

LACTATION:
Insufficient reliable information available; avoid using.

LACTICASEIBACILLUS CASEI (Lactobacillus casei)

LIKELY SAFE ...when used orally and appropriately. Lacticaseibacillus casei has been safely used alone or in combination with other ingredients in studies lasting up to 8 weeks (90230,112517).

CHILDREN: LIKELY SAFE
when used orally and appropriately in children of most ages. Lacticaseibacillus casei has been safely used alone in studies lasting up to 4 months (14373,107544). Also, a specific mixture (Latopic, Biomed S.A.) providing 1 billion CFUs of L. casei ŁOCK 0919 50%, Lacticaseibacillus rhamnosus ŁOCK 0900 25%, and L. rhamnosus ŁOCK 0908 25% has been used with apparent safety for 3 months in children under 2 years of age (107510). In addition, in children ages 4-17 years, a 1:1:1 combination of L. casei CECT 9104, Bifidobacterium animalis subsp. lactis CECT 8145, and Bifidobacterium longum CECT 7347 providing 1 billion CFUs has been used with apparent safety for 12 weeks (107531). There is insufficient reliable information available about the safety of L. casei in preterm infants with a birth weight under 1000 grams. Cases of bacteremia have occurred rarely in preterm infants given other probiotics (102416,111610,111612,111613,111850,111852,111853). The US Food and Drug Administration (FDA) has issued a warning about cases of serious infections caused by probiotics reported in very preterm or very low birth weight infants under 1000 grams (111610). Similarly, the American Academy of Pediatrics does not support the routine administration of probiotics to these infants due to conflicting data on safety and efficacy (111608).

PREGNANCY: POSSIBLY SAFE
when used orally and appropriately. A combination of Lacticaseibacillus casei, Lactobacillus acidophilus, and Bifidobacterium bifidum has been used with apparent safety for 6 weeks, starting at 24-28 weeks' gestation (95416,98430).

LACTATION:
There is insufficient reliable information available about the safety of Lacticaseibacillus casei during lactation. However, there are currently no reasons to expect safety concerns when used appropriately.

Adverse Effects view details

Report an Adverse Reaction to Vp 30

Below is general information about the adverse effects of the known ingredients contained in the product Vp 30. 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

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).

ARTICHOKE (Cynara Scolymus)

General ...Orally, artichoke extract seems to be well tolerated.
Most Common Adverse Effects:
Orally: Abdominal pain, diarrhea, flatulence, hunger, and nausea.
Topically: Contact dermatitis in sensitive individuals.
Serious Adverse Effects (Rare):
Orally: Anaphylaxis to artichoke inulin has been reported in individuals sensitive to inulin.
Topically: Chest tightness, cough, and dyspnea after occupational exposure in sensitive individuals.

Dermatologic ...Artichoke can cause an allergic reaction in some patients. Patients sensitive to the Asteraceae/Compositae family may be at the greatest risk. Members of this family include ragweed, chrysanthemums, marigolds, daisies, and many other herbs. Topically, allergic contact dermatitis can occur with the use of artichoke. This has been attributed to the constituent cynaropicrin (11,52206,52226,52230). Redness in the face (11774) and sweating (91475) have been reported rarely following oral use of artichoke extract.
Occupational or airborne exposure to artichoke may also cause allergic reactions. In one case, a 52-year-old male presented with severe spongiotic dermatitis in exposed areas that was recurrent over the past 8 years. A patch test confirmed allergies to artichokes and sesquiterpene lactones, a group of allergens from the Compositae family, and the patient confirmed occupational and airborne exposure to artichokes during the time of his symptoms. The patient improved considerably after treatment with dupilumab (111565).

Gastrointestinal ...Orally, artichoke extract might increase abdominal discomfort, flatulence, diarrhea, hunger, and nausea in some patients (2562,52238,91475). Abdominal pain and a bitter taste in the mouth were reported by a single person following oral use of a dietary supplement containing artichoke extract, as well as red yeast rice, pine bark extract, and garlic extract (89452). It is not clear if this adverse effect was due to artichoke, other ingredients, or the combination.
In one case report, the autopsy of an 84-year-old female revealed a colonic bezoar comprised of artichoke fiber and fragments. This bezoar caused complete intestinal obstruction, leading to fatal acute peritonitis. Although rare, patients who lack adequate teeth and/or who have a history of gastric surgery are at increased risk for fibrous bezoar formation (97716).

Pulmonary/Respiratory ...Following occupational exposure, allergic symptoms including dyspnea, cough, chest tightness, and asthma symptoms or exacerbation have been reported. The effects were attributed to sensitization to artichoke. Subsequent nasal challenge with artichoke extract caused reduced nasal patency in these patients (52210,52230).
Orally, severe anaphylactic shock in response to artichoke inulin as an ingredient in commercially available products has been reported (52217). Individuals with a noted sensitivity to artichokes should consume inulin with caution. While rare, individuals with a known inulin allergy should avoid artichoke and artichoke extract.

LACTICASEIBACILLUS CASEI (Lactobacillus casei)

General ...Orally, Lacticaseibacillus casei is generally well tolerated.
Most Common Adverse Effects:
Orally: Mild gastrointestinal adverse effects.
Serious Adverse Effects (Rare):
Orally: There is concern that lactobacilli may cause infections in some people.

Gastrointestinal ...Orally, taking Lacticaseibacillus casei in combination with other probiotics may cause gastrointestinal side effects including abdominal pain (90291); however, these events are uncommon.

Immunologic ...Since Lacticaseibacillus casei preparations contain live and active microorganisms, there is some concern that they might cause pathogenic infection in some patients. Some lactobacilli species have been isolated in some cases of bacteremia, sepsis, splenic abscess, endocarditis, aortic dissection, necrotizing fasciitis, pancreatic necrosis, and meningoencephalitis. Most of these cases are thought to be due to the translocation of bacteria from other locations in the body in which they occur naturally, such as the oral cavity and gastrointestinal tract. The majority of cases are not related to the use of probiotic supplements and most are not associated with the use of L. casei (107543,112516). There is at least one case of L. casei bacteremia and endocarditis thought to be related with L. casei intake in a 71-year-old immunocompromised female (112520).
There are two cases of L. casei infection in a prosthetic joint (90282,112514). In one case, the 95-year-old female with a history of hypertension, diabetes, and heart disease was known to consume yogurt containing L. casei. However, it was not confirmed that the infection was related to the consumption of this product. Spread from the gastrointestinal tract or vaginal flora could not be ruled out (90282). In the case of an 80-year-old male, the cause was unknown as there was no probiotic supplementation and no underlying medical condition or infectious portal of entry (112514).
A specific probiotic preparation (NBL probiotic ATP, Nobel) containing L. casei, Lacticaseibacillus rhamnosus, Lactiplantibacillus plantarum, Bifidobacterium animalis subsp. lactis, fructo-oligosaccharides, galacto-oligosaccharides, colostrum, and lactoferrin was found to be a significant risk factor for vancomycin-resistant Enterococcus colonization in premature infants. Although there was no direct link to determine causation, it was hypothesized that the probiotic mixture helped to mediate the acquisition and transfer of antibiotic resistance genes (96890).
