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.

• Upper respiratory tract infection (URTI). Oral American ginseng seems to prevent the incidence of URTIs in some people. Details: Some evidence shows that taking a specific American ginseng extract called CVT-E002 (Cold-FX, Afexa Life Sciences) 200-400 mg twice daily over a 3-64 month period during influenza season might modestly decrease the risk of developing symptoms of a URTI such as the common cold or flu in adults (11351,13192,14345,91275). This extract also seems to reduce symptom severity and duration of symptoms when infections do occur (13192,14345,91275). The extract might not reduce the chance of getting the first cold of a season, but it seems to reduce the risk of getting repeat colds in a season (13192). Additional evidence shows that, in people aged 65 years and older, treatment with the extract for 3-4 months, in addition to influenza vaccination at 4 weeks, is necessary before there is any significant reduction in the risk of developing a respiratory tract infection (14345). One small clinical study shows that taking the extract 200 mg twice daily orally over a 12-week period during influenza season reduces the risk of laboratory confirmed influenza or influenza and respiratory syncytial virus (RSV) infections. However, it does not seem to reduce the appearance of influenza symptoms, symptom severity, or symptom duration in these patients (11351). This same extract does not appear to prevent respiratory infections in patients who are immunocompromised. In one clinical trial, taking this extract 200 mg twice daily for 3 months did not reduce the risk of developing an acute respiratory infection, the number of days of cold symptoms, or the need for use of antibiotics when compared with placebo in patients with chronic lymphocytic leukemia (29998). Preliminary clinical research in children 3-12 years of age shows that taking the same extract 13-26 mg/kg once on the day of URTI onset, then 8.5-17 mg/kg once on the next day, then 4.5-9 mg/kg once on day three does not reduce the severity or duration of symptoms when compared with placebo. However, this study was designed to evaluate the safety and tolerability of this extract in children; therefore, it was not adequately powered to evaluate effectiveness (22365).

• Anemia of chronic disease. Although there has been interest in using oral American ginseng for anemia of chronic disease, there is insufficient reliable information about the clinical effects of American ginseng for this condition.
• Antiretroviral-induced insulin resistance. It is unclear if oral American ginseng is beneficial for antiretroviral-induced insulin resistance. Details: Preliminary clinical research in healthy volunteers shows that taking capsules containing ground American ginseng root 1 gram three times daily for 14 days along with the HIV protease inhibitor indinavir does not reduce indinavir-induced insulin resistance when compared to baseline (89401).
• Athletic performance. Early research shows that oral American ginseng does not seem to be beneficial for athletic performance. Details: Preliminary clinical research shows that taking American ginseng extract 8 mg/kg or 16 mg/kg daily (average daily dose 618-1235 mg) for one week does not improve exertion, time to exhaustion, heart rate, or maximal oxygen consumption during bicycle testing when compared with placebo (4236). Other preliminary clinical research in physically active male college students shows that taking American ginseng 1600 mg daily for 4 weeks does not enhance workout capacity when compared with placebo (14804).
• Attention deficit-hyperactivity disorder (ADHD). Oral American ginseng has only been evaluated in combination with other ingredients; its effect when used alone is unclear. Details: Preliminary clinical research shows that taking a specific combination product (AD-fX, Afexa Life Sciences) containing American ginseng extract plus ginkgo leaf extract may modestly improve ADHD symptoms such as anxiety, hyperactivity, and impulsivity in children aged 3-17 years when compared with baseline (8235). It is not clear if this effect is due to American ginseng, ginkgo, or the combination. Additionally, the validity of this finding is limited by the lack of a comparator group.
• Breast cancer. It is unclear if oral American ginseng is beneficial for breast cancer survival. Details: Population research in China suggests that breast cancer patients who regularly take any form of ginseng, including either American ginseng or Panax ginseng, have higher quality of life scores and have a lower risk of overall mortality, breast cancer-related mortality, and breast cancer recurrence compared to patients who do not take ginseng (14466). However, ginseng users were also significantly more likely to have been treated with tamoxifen.
• Cancer-related fatigue. Evidence for the use of oral American ginseng for cancer-related fatigue is conflicting. Details: Two clinical trials show that taking American ginseng 750-2000 mg in 1-2 divided doses daily for 8 weeks does not reduce cancer-related fatigue when compared with placebo (22370,104131). However, another clinical trial shows that taking American ginseng 2000 mg in two divided doses daily for 8 weeks reduces cancer-related fatigue scores by 51% after 8 weeks, compared to only 25% in those taking placebo (29996). These differing findings may be due to the instrument used to measure fatigue. The initial studies used the Brief Fatigue Inventory, whereas the positive study used the Multidimensional Fatigue Symptom Inventory-Short Form (MFSI-SF). Additionally, treatment for a shorter duration of only 4 weeks does not appear to be effective (22370,29996,104131).
• Cardiovascular disease (CVD). Although there has been interest in using oral American ginseng for CVD, there is insufficient reliable information about the clinical effects of American ginseng for this condition.
• Cognitive function. It is unclear if oral American ginseng is beneficial for cognitive function. Details: Clinical research shows that a single dose of a specific American ginseng extract (Cereboost, Naturex) 100-400 mg, taken 1-6 hours prior to cognitive testing, improves short-term working memory performance and may improve reaction time accuracy when compared with placebo in healthy young adults (22367). Other clinical research in healthy adults shows that taking the same specific American ginseng extract, standardized to contain 10% to 12% ginsenosides, as 200 mg orally daily for 14 days modestly improves memory and mental fatigue scores when compared with placebo (109518). American ginseng has also been studied in combination with other ingredients. Taking a single dose of a product containing American ginseng (Cereboost) 100 mg, bacopa 300 mg, and coffee fruit extract 100 mg modestly improves some, but not all, measures of working memory and attention after 45 minutes when compared with placebo (103375).
• Diabetes. It is unclear if oral American ginseng is beneficial for diabetes. Details: Two small clinical trials show that taking American ginseng 3 grams orally, up to two hours before a meal, can significantly reduce postprandial glucose levels in patients with type 2 diabetes when compared with placebo (1018,6461). However, doses greater than 3 grams do not seem to offer any additional benefit (6461). In addition, the postprandial glucose lowering effect of American ginseng may differ among preparations due to variations in the concentration of ginsenosides (9732). American ginseng has also been studied in combination with other ingredients. Clinical research in patients with type 2 diabetes shows that taking American ginseng 1500 mg and Panax ginseng 750 mg, enriched to contain 30% total ginsenosides, orally daily for 12 weeks reduces glycated hemoglobin by 0.35% when compared with placebo. Taking this combination also reduces systolic, but not diastolic, blood pressure by about 4 mmHg when compared with placebo (107745). It is unclear if this effect is due American ginseng, Panax ginseng, or the combination.
• Epilepsy. Although there has been interest in using oral American ginseng for epilepsy, there is insufficient reliable information about the clinical effects of American ginseng for this condition.
• Headache. Although there has been interest in using oral American ginseng for headaches, there is insufficient reliable information about the clinical effects of American ginseng for this purpose.
• HIV/AIDS. Although there has been interest in using oral American ginseng for HIV/AIDS, there is insufficient reliable information about the clinical effects of American ginseng for this condition.
• Hypertension. Evidence on the use of oral American ginseng for hypertension is conflicting. Details: Some clinical research shows that taking American ginseng 1500 mg twice daily for 12 weeks does not reduce blood pressure when compared with placebo in patients with hypertension (22368,22369). However, other clinical research shows that taking American ginseng extract 1000 mg three times daily for 12 weeks lowers systolic blood pressure by 12% when compared with baseline in patients with type 2 diabetes and hypertension (29999). In a similar study in patients with type 2 diabetes and hypertension, American ginseng extract 500 mg in combination with Panax ginseng extract 250 mg three times daily for 12 weeks, providing 30% total ginsenosides daily, reduces central systolic blood pressure by about 5 mmHg, but not diastolic blood pressure, when compared with placebo (103046). These differing results may be due to the higher amount of total ginsenosides provided in the latter study.
• Menopausal symptoms. Oral American ginseng has only been evaluated in combination with other ingredients; its effect when used alone is unclear. Details: Preliminary clinical research during pre- and post-menopause shows that taking a specific combination product (Phyto-Female Complex, SupHerb) containing black cohosh root extract 100 mg, dong quai root extract 75 mg, milk thistle extract 75 mg, red clover flower extract 50 mg, American ginseng root extract 50 mg, and vitex agnus-castus fruit extract 50 mg twice daily for 12 weeks improves sleep quality and reduces menopausal symptoms, including the number and intensity of hot flashes and the number of night sweats, when compared with placebo (19552). However, it is unclear whether these effects are due to American ginseng, other ingredients, or the combination.
• Schizophrenia. It is unclear if oral American ginseng is beneficial for schizophrenia. Details: Preliminary clinical research in adults with schizophrenia who are taking antipsychotics shows that taking a specific American ginseng extract (HT1001, Afexa Life Sciences) 100 mg twice daily for 4 weeks modestly increases visual working memory score when compared with placebo. This treatment also reduces physical symptoms associated with antipsychotic use, such as abnormal gait or muscle rigidity. However, it does not appear to improve other clinical symptoms or parameters related to cognitive function, such as verbal working memory, sustained attention, verbal function, or immediate or delayed auditory memory, when compared with placebo (29997).
• Ulcerative colitis. Although there has been interest in using oral American ginseng for ulcerative colitis, there is insufficient reliable information about the clinical effects of American ginseng for this condition. More evidence is needed to rate American ginseng for these uses.

• Angina. Although there has been interest in using oral chrysanthemum for angina, there is insufficient reliable information about the clinical effects of chrysanthemum for this purpose.
• Asthenopia (eye strain). Oral chrysanthemum has only been evaluated in combination with other ingredients; its effect when used alone is unclear. Details: Clinical research in patients with asthenopia shows that taking one of three doses of a combination tablet containing chrysanthemum extract 75 mg, 125 mg, or 175 mg with various other ingredients orally once daily for 90 days modestly improves symptoms of eye fatigue, such as tearing, soreness, dryness, and foreign body sensation, when compared with placebo. There were also improvements in macular function. The other ingredients included black currant extract 100-233 mg, goji berry extract 75-175 mg, lutein ester 12-28 mg, and zeaxanthin 1.2-2.8 mg (106306).
• Common cold. Although there has been interest in using oral chrysanthemum for the common cold, there is insufficient reliable information about the clinical effects of chrysanthemum for this purpose.

• Hypertension. Although there has been interest in using oral chrysanthemum for hypertension, there is insufficient reliable information about the clinical effects of chrysanthemum for this purpose.
• Osteoarthritis. It is unclear if oral chrysanthemum is beneficial in patients with osteoarthritis. Details: Clinical research in patients with mild knee osteoarthritis shows that taking a specific chrysanthemum extract (GreenCross Wellbeing Corporation) 250 mg orally daily for 12 weeks reduces certain pain scores by 30% when compared with baseline. This was also statistically significant when compared with the 14% reduction in those taking placebo. However, other pain scores and stiffness scores were not different between groups. In addition, the clinical significance of these potential improvements is unclear (106308).
• Stroke. It is unclear if oral chrysanthemum is beneficial in patients with stroke. Details: Preliminary clinical research in adults with ischemic stroke shows that taking chrysanthemum extract 200 mg orally twice daily for 4 days improves stroke symptom scores when compared with control (110511).
• Ulcerative colitis. Although there has been interest in using oral chrysanthemum for ulcerative colitis, there is insufficient reliable information about the clinical effects of chrysanthemum for this purpose. More evidence is needed to rate chrysanthemum for these uses.

• Constipation. Taking senna orally is effective for the short-term treatment of constipation. Details: Senna is an FDA-approved nonprescription drug marketed for the short-term treatment of constipation in adults and children ages 2 years and older (15429,15433,15436,15441,15442,74545,74607,74609,74613,74615). Senna usually produces a laxative effect 6-10 hours after oral administration (15429,96559). However, in children ages 3-15 years, mineral oil and lactulose might be more effective (15434,15435). Taking senna with psyllium is also effective for the short-term treatment of constipation (8424,74593), with the combination increasing stool moisture to a greater degree than psyllium alone (8424). In patients with opioid or loperamide-induced constipation, taking senna appears to be as effective as lactulose, psyllium, and docusate for relieving constipation (15432,74586,74644,74650). Some population research has found that senna may be more effective than docusate, polyethylene glycol, and lactulose for preventing problematic constipation, the need for an enema, and abdominal imaging in pediatric cancer patients receiving opioids (92710). Senna also seems to be beneficial in chronic constipation. Clinical guidelines published by the American Gastroenterology Association and American College of Gastroenterology in 2023 give a conditional recommendation suggesting the use of senna over managing chronic idiopathic constipation without senna based on low-quality of evidence conducted over 4 weeks (112859). In geriatric patients, senna plus psyllium is more effective than lactulose for treating chronic constipation (15438,15439,15440). Also, a small study in middle-aged adults with chronic idiopathic constipation shows that taking senna (ALOSENN granules) 500 mg twice daily for 4 weeks seems to be similarly effective to taking magnesium oxide 500 mg three times daily (105959).

POSSIBLY EFFECTIVE

• Bowel preparation. Taking oral senna might be effective for bowel cleansing before colonoscopy. Details: A meta-analysis of 10 clinical trials in adults shows that taking senna alone or with other bowel preparations does not improve bowel cleansing before elective colonoscopy when compared with non-senna bowel preparations. However, in a subgroup analysis of 3 clinical studies, taking senna solution alone is about 2.5 times more likely to result in a clean bowel when compared with polyethylene glycol alone (112893). The interpretation of these findings is limited by varied senna dosages and regimens. Additionally, 2 clinical studies that were not included in this meta-analysis show that senna is as effective or more effective than polyethylene glycol for improving bowel cleanse quality (15431,40088). Conversely, other studies show that polyethylene glycol is superior to senna (40086,74587,74606,74636). It is also unclear if taking senna with polyethylene glycol improves bowel cleansing when compared with polyethylene glycol alone (74583,74585). Some clinical studies show that senna is as effective as castor oil and bisacodyl for bowel cleansing (74548,74603,74624). Although taking senna alone is less effective than sodium phosphate (15431,74567,74570,74653,92712), some evidence suggests that taking a combination of senna, sodium picosulfate, and polyethylene glycol is more effective than sodium phosphate for bowel cleansing prior to colonoscopy (74538). Limited research has also assessed the benefit of adding senna to a preparation regimen for small bowel capsule endoscopy; however, it is unclear whether the addition of senna improves endoscopy outcomes when compared with the preparation regimen alone (96557). There is insufficient reliable information available about the effectiveness of senna for its other uses.

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

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).

General ...There is limited information available about the potential adverse effects of Asian water plantain. Orally, it has been used as a part of Traditional Chinese Medicine (TCM) with apparent safety; there have been no reported adverse effects in most patients. However, one case of hepatotoxicity and nephrotoxicity has been reported with the use of a combination TCM product containing Asian water plantain (99434).

Hepatic ...One case report of drug-induced systemic toxicity, including hepatotoxicity, has occurred in a 59-year-old man with chronic hepatitis B who had taken six doses of a combination product containing Asian water plantain 3 weeks prior to admission. He presented with gum bleed and petechiae, and his admission lab values indicated fulminant liver failure. His condition progressed to include renal failure and eventual death after 4 weeks. It is not clear if Asian water plantain, the other ingredients, or the combination caused this toxicity. However, the authors identified Asian water plantain as the likely causative ingredient based on animal research (99434).

Renal ...One case report of drug-induced systemic toxicity, including nephrotoxicity, has occurred in a 59-year-old man with chronic hepatitis B who had taken six doses of a combination product containing Asian water plantain 3 weeks prior to admission. He initially presented with hepatic failure, which progressed to include renal failure and eventual death after 4 weeks. It is not clear if Asian water plantain, the other ingredients, or the combination caused this toxicity. However, the authors identified Asian water plantain as the likely causative ingredient based on animal research (99434).

General ...There is currently a limited amount of information on the adverse effects of chrysanthemum. A thorough evaluation of safety outcomes has not been conducted.
Most Common Adverse Effects:
Topically: Allergic reactions, contact dermatitis, eczema, urticaria.
Serious Adverse Effects (Rare):
Topically: Asthma.

Immunologic ...Topically and via occupational exposure, chrysanthemum can cause allergic reactions. Chrysanthemum allergy symptoms can include urticaria, contact dermatitis, eczema, actinic reticuloid photosensitivity dermatitis, pollinosis, rhinoconjunctivitis, and asthma (5552,5554,5556,5557,6958,42842,42845,42849,42859,42867,42893,42872,42873,42874)(42879,42880,42881,42882,42883,42887,42888). There are numerous case reports and studies showing that allergies to Chrysanthemum are very common, with an estimated 60% of Europeans being allergic (19149,42847,42856,42854).

General ...Orally, adverse effects to lotus seem to be rare when taken in medicinal amounts; however, a thorough safety evaluation has not been conducted.

Immunologic ...Orally and topically, lotus root can cause allergic reactions such as urticaria and contact dermatitis. In a case report, a 6-year-old female developed urticaria after ingesting lotus root. She had also developed contact dermatitis on body areas that had been in contact with the lotus root (99738).

General ...Orally, senna is generally well-tolerated when used short-term in appropriate doses.
Most Common Adverse Effects:
Orally: Abdominal pain and discomfort, cramps, diarrhea, flatulence, nausea, fecal urgency, and urine discoloration.
Serious Adverse Effects (Rare):
Orally: Skin eruptions.

Cardiovascular ...Excessive use can cause potassium depletion and other electrolyte abnormalities (15425). In theory, this could cause potentially dangerous changes in heart rhythm. A small decrease in heart rate was seen in one clinical study (74587).

Dermatologic ...In adults, there are rare case reports of skin eruptions associated with senna, including erythema multiforme, fixed drug eruption, lichenoid reaction, toxic epidermal necrolysis, urticaria, photosensitivity, and contact dermatitis (96558). Infants and young children given senna products have experienced contact reactions on the buttocks due to prolonged exposure to stool while wearing a diaper overnight. These reactions range from erythema with small blisters, to large fluid-filled blisters with skin sloughing, as occurs with second degree burns (96559). In a case series of children treated with senna for chronic constipation, burn-like reactions occurred in 2.2%, typically with higher doses (mean 60 mg/day, range 35.2 to 150 mg/day) (96558,96559). These reactions can be avoided by giving senna early in the day, so that bowel movements occur at a time when diapers can be changed quickly (96559).

Gastrointestinal ...Orally, senna can cause abdominal pain and discomfort, cramps, bloating, flatulence, nausea, fecal urgency, and diarrhea (15427,15434,15435,15436,15439,15440,15441,105955). Chronic use has also been associated with "cathartic colon," radiographically diagnosed anatomical changes to the colon such as benign narrowing, colonic dilation, and loss of colonic folds (15428). The clinical relevance of these findings is unclear. Chronic use can also cause pseudomelanosis coli (pigment spots in intestinal mucosa) which is harmless, usually reverses with discontinuation, and is not associated with an increased risk of developing colorectal adenoma or carcinoma (6138). The cathartic properties of senna leaf are greater than the fruit (15430). Thus, the American Herbal Products Association only warns against long-term use of senna leaf (12).

Hepatic ...Chronic liver damage, portal vein thrombosis, and hepatitis have been reported following oral use of senna alkaloids, such as in tea made from senna leaves (13057,13095,41431,74560,74564,74584,105956). There is a case report of hepatitis in a female who consumed moderate amounts of senna tea. The patient was a poor metabolizer of cytochrome P450 2D6 (CYP2D6). It's thought that moderate doses of senna in this patient led to toxic hepatitis due to the patient's reduced ability to metabolize and eliminate the rhein anthrone metabolites of senna, which are thought to cause systemic toxicity (13057). There is also a case of liver failure, encephalopathy, and renal insufficiency in a female who consumed 1 liter/day of senna tea, prepared from 70 grams of dried senna fruit, over 3 years (13095). In another case report, a 3-year-old female presented with hepatitis that led to pancytopenia after drinking tea made from 2-3 grams dry senna leaves three times or more weekly for over one year (105956).

Immunologic ...In one case report, a 19-year-old male developed anaphylaxis with dyspnea, facial edema, and hives. This reaction was determined to be caused by the senna content in a specific combination product (Delgaxan Plus, Pompadour Ibérica) that the patient ingested (105957).

Musculoskeletal ...Hypertrophic osteoarthropathy, finger clubbing, cachexia, and tetany have been reported from excessive oral senna use in humans (15426,74580,74582,74620,74625).

Renal ...Nephrocalcinosis has been reported as a result of oral senna overuse (74582).
