• Asthma. Clinical research in patients with asthma shows that taking 100 mg of a specific product (AlvioLife) containing a 1:1 combination of bael fruit and boswellia gum resin extracts twice daily for 8 weeks improves activity, asthma symptoms, and emotions compared with placebo. The improvement in the maximum speed of expiration was approximately double that of placebo. The amount of air exhaled during a forced breath was not improved (99299). It is unclear if these effects are due to bael, boswellia, or the combination.
• Shigellosis. Preliminary clinical research shows that taking dried bael fruit powder 6 grams daily for 3 days does not reduce the number of stools in patients with diarrhea due to shigellosis (33330). More evidence is needed to rate bael for these uses.

• Amenorrhea. Although there is interest in using oral bitter melon for amenorrhea, there is insufficient reliable information about the clinical effects of bitter melon for this condition.
• Athletic performance. It is unclear if oral bitter melon is beneficial for improving athletic performance. Details: Preliminary clinical research in ten male tennis players taking part in high-intensity training at high temperatures shows that taking bitter melon extract orally, 100 mL six times daily for 4 weeks, improves some biomarkers of fatigue and physical fitness parameters including balance, flexibility, and cardiorespiratory fitness when compared with baseline. Levels of adrenocorticotrophic hormone and cortisol are decreased, suggesting a reduction in oxidative stress (103295,106407). The validity of these results is limited by the lack of a comparator group.
• Constipation. Although there is interest in using oral bitter melon for constipation, there is insufficient reliable information about the clinical effects of bitter melon for this purpose.
• Diabetes. Although some research suggests that bitter melon may improve glycemic control in adults with type 2 diabetes, evidence is conflicting and of limited quality. Details: A meta-analysis of 10 low-quality studies in patients with type 2 diabetes shows that taking bitter melon powdered whole fruits or juice in doses of 0.5 to 12 grams daily for 4-16 weeks reduces fasting blood glucose (FBG) by 13 mg/dL, postprandial glucose by 26 mg/dL, and glycated hemoglobin (HbA1c) by 0.26% when compared with placebo (100632). Another meta-analysis, pooling the results of 7 trials in patients with type 2 diabetes, shows that bitter melon modestly reduces HbA1c by 0.3% and FBG by 14 mg/dL when compared with no treatment, but a separate analysis of 2 other trials shows that bitter melon does not improve either outcome when compared with oral antidiabetic drugs (111503). Additionally, a meta-analysis of 3 clinical trials shows that taking bitter melon 1-6 grams daily for 4-12 weeks does not significantly improve fasting plasma glucose or HbA1c when compared with placebo in patients with type 2 diabetes (92124). Some other clinical research in patients with type 2 diabetes shows that bitter melon fruit, fruit pulp, fruit juice, and extract improve glucose tolerance and insulin secretion, reduce blood glucose levels, and lower HbA1c (34,35,36,38,12530). One clinical study shows that taking powdered bitter melon fruit 2-4 grams daily for 10 weeks lowers HbA1c similarly to glyburide 2.5 mg daily (92126). Reasons for the discrepancies among the evidence are not clear but may relate to the small study sizes, shorter durations of treatment, and varying dosages and formulations of bitter melon.
• Dyspepsia. Although there is interest in using oral bitter melon for dyspepsia, there is insufficient reliable information about the clinical effects of bitter melon for this purpose.
• Genital herpes. Although there is interest in using topical bitter melon for genital herpes, there is insufficient reliable information about the clinical effects of bitter melon for this condition.
• HIV/AIDS. Although there is interest in using oral bitter melon for HIV/AIDS, there is insufficient reliable information about the clinical effects of bitter melon for this condition.
• Impaired glucose tolerance (prediabetes). It is unclear if oral bitter melon is beneficial in patients with prediabetes. Details: A small clinical study in patients with impaired glucose tolerance shows that drinking a beverage containing bitter melon extract 1.25-3 grams as a single dose does not affect blood glucose or insulin response when compared with baseline (97508). A moderate-sized clinical study in adults with prediabetes shows that taking bitter melon (SugarKatcherS52, Kolmar BNH) 800 mg three times daily for 12 weeks reduces blood glucose by 22 mg/dL two hours after oral glucose tolerance test when compared with placebo, but does not improve insulin, C-peptide, or glucagon levels, nor markers of insulin resistance (112372). The validity of these results is limited by the lack of statistical adjustment for multiple comparisons which can lead studies to erroneously show differences between treatment groups (i.e., false positive findings).
• Intestinal parasite infection. Although there is interest in using oral bitter melon for intestinal parasite infection, there is insufficient reliable information about the clinical effects of bitter melon for this condition.
• Kidney stones (nephrolithiasis). Although there is interest in using oral bitter melon for kidney stones, there is insufficient reliable information about the clinical effects of bitter melon for this condition.
• Liver disease. Although there is interest in using oral bitter melon for liver disease, there is insufficient reliable information about the clinical effects of bitter melon for this condition.
• Metabolic syndrome. Although there is interest in using oral bitter melon for metabolic syndrome, there is insufficient reliable information about the clinical effects of bitter melon for this condition.
• Obesity. It is unclear if oral bitter melon is beneficial for weight loss. Details: A very small clinical study in patients with obesity shows that taking bitter melon 1 gram twice daily for 12 weeks does not reduce body weight, body mass index (BMI), waist circumference, or body fat percentage when compared to baseline. However, when compared with placebo, body weight and BMI were reduced by around 4 kg and 1.6 kg/m², respectively. Patients in the placebo group experienced an increase in these measures (109583).
• Osteoarthritis. It is unclear if oral bitter melon is beneficial in patients with osteoarthritis. Details: A small preliminary clinical study in patients with osteoarthritis shows that taking bitter melon 1500 mg three times daily for 3 months reduces the need for rescue analgesic medications when compared with placebo. However, subjective scores of osteoarthritis symptoms improved similarly in both groups (100631).
• Peptic ulcers. Although there is interest in using oral bitter melon for peptic ulcers, there is insufficient reliable information about the clinical effects of bitter melon for this condition.
• Polycystic ovary syndrome (PCOS). Although there is interest in using oral bitter melon for PCOS, there is insufficient reliable information about the clinical effects of bitter melon for this condition.
• Psoriasis. Although there is interest in using oral bitter melon for psoriasis, there is insufficient reliable information about the clinical effects of bitter melon for this condition.
• Ulcerative colitis. Although there is interest in using oral bitter melon for ulcerative colitis, there is insufficient reliable information about the clinical effects of bitter melon for this condition.
• Wound healing. Although there is interest in using topical bitter melon for wound healing, there is insufficient reliable information about the clinical effects of bitter melon for this purpose. More evidence is needed to rate bitter melon for these uses.

POSSIBLY EFFECTIVE

• Diabetes. Oral fenugreek seed seems to improve glycemic control in type 2 diabetes. Details: Meta-analyses of 10-14 clinical trials in patients with type 2 diabetes or other metabolic conditions show that taking fenugreek lowers fasting glucose by approximately 14-23 mg/dL, 2-hour postprandial glucose by 21-23 mg/dL, and glycated hemoglobin (HbA1c) by 0.6-1.2% when compared with placebo. The most effective doses and formulations seem to include powdered seed or debitterized seed powder 5-100 grams daily, taken as capsules or added to meals, for up to 3 years or seed hydroalcoholic extract about 1 gram daily for up to 2 months (90112,96065,105016,111503,113499,112120). The validity of these effects is limited by high heterogeneity and low quality in the included studies. Most research also shows that fenugreek seed lowers total cholesterol levels and triglycerides in patients with diabetes, but has inconsistent effects on low-density lipoprotein (LDL) cholesterol and high-density lipoprotein (HDL) cholesterol (96065,102252). Some research shows that taking fenugreek in combination with other ingredients also seems to improve glycemic indices in people with diabetes. These combination products have combined fenugreek with guar gum and gymnema (10284) or millets and legumes (9784). Limited research has also evaluated fenugreek in type 1 diabetes. In one small clinical study, taking 50 grams of defatted fenugreek seed powder twice daily with meals for 10 days reduced 24-hour urine glucose levels by 54% when compared to baseline (622). The validity of this finding is limited by the lack of a comparator group.
• Dysmenorrhea. Oral fenugreek seed might help to reduce menstrual pain. Details: Clinical research in adults with moderate to severe dysmenorrhea shows that taking fenugreek seed powder 1800-2700 mg three times daily for the first 3 days of menstruation followed by 900 mg three times daily for the remainder of two menstrual cycles reduces pain severity when compared with placebo. Patients taking fenugreek seed powder showed a reduction in pain severity of 3.22, compared with a reduction of only 0.18 in the placebo group (90116).
• Sexual arousal. Oral fenugreek seed might help to improve sexual arousal. Details: Clinical research shows that taking a specific fenugreek seed extract (Testofen, Gencor Pacific Ltd) 600 mg daily for 12 weeks increases sexual function by 15% over baseline, compared with no change in the placebo group; the main benefits were in sexual arousal and drive. Morning erection and sexual frequency also improve by 2- to 3-fold (93419). Another clinical study in healthy males shows that taking the same fenugreek seed extract 600 mg daily in combination with magnesium 34 mg, zinc 30 mg, and vitamin B6 10 mg for 6 weeks, improves a composite of symptoms such as sexual cognition, sexual arousal, sexual behavior, and orgasm. The overall improvement in the composite score was 23%, compared with a worsening in the placebo group (93421).
• Sexual dysfunction. Oral fenugreek seed extract might help to improve sexual dysfunction. Details: Clinical research shows that taking a specific fenugreek seed extract (Libifem, Gencor Pacific Ltd.) 300 mg twice daily for two menstrual cycles improves sexual function in healthy pre-menopausal adults with low sex drive. In one clinical trial, overall improvement based on a composite of symptoms was 26% in the fenugreek group, compared with only 2% in the placebo group. Individual scores for sexual cognition, arousal, behavior, drive, and orgasm were all improved. Patients taking fenugreek also had an increased frequency of sexual activity from 1-2 times per month to once per week, compared to no change in the placebo group (93420). Other clinical research in males aged 35-60 years with symptomatic hypogonadism shows that taking a specific fenugreek seed extract (Furosap; Chemical Resources) 500 mg daily after breakfast for 12 weeks improves sexual arousal, mental alertness, and mood when compared with baseline. This fenugreek seed extract was fortified with 20% protodioscin; the other constituents were not specified (108700). The validity of this finding is limited by the lack of comparator group.

POSSIBLY INEFFECTIVE

• Benign prostatic hyperplasia (BPH). Oral fenugreek extract does not seem to improve BPH symptoms. Details: A clinical study in healthy adults with BPH shows that taking a specific fenugreek extract (Testofen, Bluegum Pharmaceuticals) 300 mg twice daily for 12 weeks does not improve BPH symptoms when compared with placebo (102253).

• Alopecia areata. Although there is interest in using oral fenugreek for alopecia areata, there is insufficient reliable information about the clinical effects of fenugreek for this condition.
• Alzheimer disease. It is unclear if oral fenugreek seed extract is beneficial for Alzheimer disease. Details: A moderate-sized study in adults with mild to moderate Alzheimer disease shows that taking fenugreek seed extract 5 mL daily for 4 months modestly improves memory but does not improve depression or quality of life measures when compared with placebo (113498).
• Athletic performance. It is unclear if oral fenugreek seed is beneficial for improving athletic performance. Details: Two small clinical studies in resistance-trained young males shows that taking a fenugreek supplement (AI or Torabolic, Indus Biotech) 500 mg daily for 8 weeks in addition to training 4 days every week, decreases body fat by about 2% and sometimes increases leg and bench press performance, but does not improve power, when compared with placebo (18352,18353). Another small study in healthy males undergoing strength training also shows that taking a specific fenugreek extract enriched in furostanol glycosides (Fenu-FG, Indus Biotech Private Limited) 300 mg twice daily for 8 weeks might help to modestly increase the number of bench press repetitions, but not overall strength, when compared with placebo (93423).
• Atopic dermatitis (eczema). Although there is interest in using topical fenugreek for eczema, there is insufficient reliable information about the clinical effects of fenugreek for this condition.
• Cough. Although there is interest in using oral fenugreek for cough, there is insufficient reliable information about the clinical effects of fenugreek for this purpose.
• Gastroesophageal reflux disease (GERD). It is unclear if oral fenugreek fiber is beneficial for improving heartburn symptoms. Details: A small clinical study in patients with frequent heartburn shows that taking a specific fenugreek fiber product (FenuLife, Frutarom Belgium), 2 grams twice daily 30 minutes before the two biggest meals of the day, improves heartburn after one week of treatment and continuing through the 2-week study period. Fenugreek seemed to be similarly effective to ranitidine 75 mg twice daily (17372).
• Gout. Although there is interest in using topical fenugreek for gout, there is insufficient reliable information about the clinical effects of fenugreek for this condition.
• Hyperlipidemia. Small clinical studies suggest that oral fenugreek supplements might be beneficial for improving lipid levels. Details: Overall, fenugreek powdered seed seems to modestly reduce lipid levels in people with or without hyperlipidemia; however, most studies have been low-quality, small, and exploratory. Meta-analyses of these studies show that fenugreek reduces total cholesterol, low-density lipoprotein (LDL) cholesterol, and triglycerides, and increases high-density lipoprotein (HDL) cholesterol (103283,103284). Powdered fenugreek seed has been studied in doses of 0.5-100 grams daily for 10 days to 3 years. While some studies show modest improvement, others show no benefit (622,7389,9783,18359,18361,18362,102252,103283,103284,113497).
• Hypertension. Analysis of small clinical studies suggests that oral fenugreek might slightly improve systolic blood pressure (SBP). Details: A meta-analysis of 6 small clinical studies in healthy adults or those with diabetes, prediabetes, or metabolic syndrome shows that taking fenugreek seed 0.5-50 grams daily for 6-144 weeks reduces SBP by 3.5 mmHg but does not improve diastolic blood pressure (DBP) when compared with placebo. However, subgroup analysis suggests that taking fenugreek at a dose of 15 grams or more daily or for a duration of 12 weeks or less modestly reduces DBP (112110).
• Impaired glucose tolerance (prediabetes). It is unclear if oral fenugreek is beneficial in patients with prediabetes. Details: A small clinical study in adults with prediabetes shows that taking a specific fenugreek seed extract (Trigogen, Gencor Pacific Ltd.) 250 mg twice daily for 12 weeks reduces fasting blood glucose and postprandial blood glucose but not glycated hemoglobin (HbA1c), fasting insulin, or postprandial insulin when compared with placebo (113497). Another small clinical trial in patients with prediabetes shows that taking fenugreek seed extract 200 mg, bergamot extract 500 mg, and olive leaf extract 100 mg daily for 6 months does not improve glycated hemoglobin or fasting blood glucose when compared with placebo (102251).
• Joint pain. Although there is interest in using oral fenugreek for joint pain, there is insufficient reliable information about the clinical effects of fenugreek for this condition.
• Lactation. Small clinical studies suggest that oral fenugreek, either as a supplement or tea, might increase lactation. Details: A network meta-analysis of 4 small clinical trials shows that taking fenugreek shortly after delivery may modestly increase breast milk production when compared with placebo. Patients in the included studies took fenugreek 1-2 grams as capsules or tea up to 3 times daily for 21-244 days. In most cases, fenugreek treatment was initiated one or two days after delivery. However, fenugreek might be less beneficial for breast milk production when compared with the natural ingredients Indian borage or palm date (96067). Fenugreek has also been used in combination with other ingredients. A small clinical study suggests that drinking a specific herbal tea containing fenugreek. hibiscus, fennel, rooibos, vervain, raspberry, goat's rue, and fennel oil (Humana Still-Tee, Humana, Germany) 200 mL three times daily modestly increases milk production when compared with placebo (22569). Another study in exclusively breastfeeding parents of 2-month-old infants shows that eating lactation cookies containing fenugreek, oatmeal, brewer's yeast, and flaxseed meal daily for 30 days do not improve milk production, perceived insufficiency, or breastfeeding self-efficacy when compared with control (112116).
• Male infertility. It is unclear if oral fenugreek seed is beneficial for improving sperm quality in males with infertility. Details: A small clinical study in healthy male patients ages 20-30 years with oligospermia shows that taking fenugreek seed oil 12 macro drops orally three times daily for 4 months improves sperm count from 6.2 million to 20.1 million, increases sperm motility from 43% to 61%, and reduces sperm abnormality from 68% to 53% when compared with baseline. However, taking the remaining fenugreek seed components 10 grams three times daily for 4 months does not seem to have this effect (90119). The validity of this finding is limited by the lack of a comparator group.
• Menopausal symptoms. It is unclear if oral fenugreek seed is beneficial for improving menopausal symptoms. Details: A small clinical study in perimenopausal patients shows that taking a specific fenugreek seed extract (FenuSMART) 250 mg, standardized to protodioscin 10.3%, trigonelline 3.1%, and total saponin 42.6%, twice daily with meals for 42 days does not improve menopausal symptoms when compared with placebo. However, there was a non-significant trend to reduced hot flashes, night sweats, depression, and insomnia in the treatment group (105000). This study was funded by the supplement manufacturer.
• Metabolic syndrome. It is unclear if oral fenugreek seed is beneficial for metabolic syndrome. Details: A meta-analysis of 29 small clinical studies in healthy adults or those with type 2 diabetes or other metabolic conditions shows that taking fenugreek at doses ranging from 25 mg to 60 grams daily for up to 144 weeks reduces fasting blood glucose by 17 mg/dL, triglycerides by 20 mg/dL, waist circumference by 2.5 cm, and systolic blood pressure by 3.5 mmHg and increases high-density lipoprotein cholesterol by 3.5 mg/dL when compared with control. However, no effect was found on diastolic blood pressure or body mass index (113500).
• Muscle strength. It is unclear if oral fenugreek seed is beneficial for increasing muscle strength. Details: A small study in healthy, active males shows that taking fenugreek seed extract 400 mg or 500 mg daily for 60 days increases grip strength when compared with placebo (103285).
• Myalgia. Although there is interest in using topical fenugreek for myalgia, there is insufficient reliable information about the clinical effects of fenugreek for this condition.
• Obesity. Small clinical studies suggest that oral fenugreek seed or fiber may increase satiety and decrease caloric intake. Details: Two small clinical studies in overweight and normal weight males shows that taking fenugreek seed extract modestly reduces daily fat intake. At a dose of 392 mg three times daily for 2-6 weeks, fat intake is reduced by 13% to 17%. However, a lower dose of 196 mg three times daily appears to be ineffective. Neither of the doses affect weight, appetite, or satiety (18348,18349). Another small clinical study in obese adults shows that adding 8 grams of fenugreek fiber powder (FenuLife, Frutarom Inc) to a low-calorie beverage increases feelings of satiety and decreases hunger and lunchtime food intake. A lower dose of 4 grams appears to be less effective for reducing hunger but was considered to be more palatable (18350).
• Parkinson disease. It is unclear if oral fenugreek seed is beneficial for Parkinson disease symptoms. Details: One small clinical study in patients with Parkinson disease who are also using levodopa shows that taking fenugreek seed extract (Indus Biotech Private Limited, Pune) 300 mg twice daily for 6 months does not seem to improve behavioral or motor symptoms when compared with placebo (90113).
• Peptic ulcers. Although there is interest in using oral fenugreek for peptic ulcers, there is insufficient reliable information about the clinical effects of fenugreek for this condition.
• Polycystic ovary syndrome (PCOS). It is unclear if oral fenugreek seed is beneficial for PCOS. Details: A small clinical study in adults with symptomatic PCOS shows that adding a specific fenugreek seed extract (Goldarou Pharmaceutical Co.) 500 mg twice daily to metformin for 8 weeks does not improve insulin resistance, insulin sensitivity, or other symptoms when compared with placebo and metformin (90117). However, other small clinical studies in adults with PCOS show that taking another specific fenugreek seed extract (Furocyst, Cepham Inc.) 1000 mg, enriched with 40% furostanolic saponins, daily for 90 days is associated with a reduction in ovarian cyst size in 46% of patients, complete dissolution in 36% of patients, normalization of menstrual cycles in 71% to 80% of patients, and subsequent pregnancy in 12% of patients. Further, this extract appears to reduce mean cyst size by 42% to 45%, the number of cysts by 38%, ovary volume by 24% to 40%, and hirsutism by 27% while reducing luteinizing hormone, follicle-stimulating hormone, free testosterone, and prolactin and improving liver function and the severity of PCOS-associated ailments including insulin resistance and dyslipidemia (93422,112112,113502). The validity of some of these findings is limited by the lack of a comparator group. Furthermore, this study was funded by the supplement manufacturer.
• Vaginitis. There is limited evidence on the topical use of fenugreek cream in patients with atrophic vaginitis. Details: One small clinical study in postmenopausal patients with atrophic vaginitis shows that administration of 0.5 grams of fenugreek 5% cream intravaginally twice weekly for 12 weeks reduces symptoms of atrophic vaginitis and reduces vaginal pH when compared to baseline. However, fenugreek was not as effective as vaginal cream containing conjugated estrogens (103286). Another small clinical study in postmenopausal patients with vaginal atrophy shows that applying a fenugreek cream 5% intravaginally daily for 8 weeks seems to reduce dyspareunia and vaginal dryness and increase vaginal maturation when compared with a placebo cream (105023).
• Wound healing. Although there is interest in using topical fenugreek for wound healing, there is insufficient reliable information about the clinical effects of fenugreek for this purpose. More evidence is needed to rate fenugreek for these uses.

• Diabetes. It is unclear if oral gymnema is beneficial for diabetes. Details: A meta-analysis of 10 small clinical studies in adults with type 2 diabetes shows that taking gymnema modestly reduces fasting and postprandial blood glucose levels, and also seems to reduce glycated hemoglobin (HbA1c), when compared to baseline. Gymnema may also modestly reduce total cholesterol and triglyceride levels. (110022). Another meta-analysis of 6 small clinical studies, that includes some of the same studies, also shows that taking gymnema modestly reduces fasting blood glucose, total cholesterol, and triglyceride levels when compared with diet or placebo. However, this analysis shows that gymnema does not improve HbA1c, oral glucose tolerance, or low-density lipoprotein cholesterol (112184). The validity of these analyses is limited by the inclusion of mostly low-quality studies that enrolled heterogeneous patient populations and employed varying gymnema dosing regimens of 0.4-10 grams daily, sometimes in conjunction with antidiabetes medications. In addition, many of the included studies were non-randomized and lacked a comparator group.
• Impaired glucose tolerance (prediabetes). It is unclear if oral gymnema is beneficial for impaired glucose tolerance. Details: One small clinical study in overweight or obese patients with impaired glucose tolerance shows that taking gymnema (Swanson Superior Herbs) 300 mg twice daily for 12 weeks does not improve glucose control, lipid profile, anthropometric indices, or blood pressure when compared with placebo (105346). However, this study may have been inadequately powered to detect a difference between groups.
• Metabolic syndrome. It is unclear if oral gymnema is beneficial for metabolic syndrome. Details: One small clinical study shows that taking gymnema leaf (Swanson Premium G. sylvestre leaf, Swanson Health Products) 300 mg twice daily for 12 weeks reduces body weight by 4% and body mass index (BMI) by 2% when compared to baseline in overweight adults with metabolic syndrome. However, it is unclear if these changes are significant when compared with placebo. In addition, gymnema does not appear to improve blood glucose levels, insulin sensitivity, or blood lipid levels when compared with placebo (96235).
• Obesity. It is unclear if oral gymnema improves weight loss in overweight or obese adults. Details: One small clinical study shows that taking gymnema leaf (Swanson Premium G. sylvestre leaf, Swanson Health Products) 300 mg twice daily for 12 weeks modestly reduces body weight and body mass index (BMI) when compared to baseline in overweight adults with metabolic syndrome. However, it is unclear if these changes are significant when compared with placebo (96235). Another small clinical study by the same authors evaluating overweight adults with impaired glucose tolerance shows that taking gymnema (Swanson Superior Herbs) 300 mg twice daily for 12 weeks does not reduce body weight or BMI when compared with placebo (105346). Gymnema has also been studied in combination with other ingredients. One small clinical study shows that taking a combination of gymnema extract 400 mg, hydroxycitric acid 2800 mg, and niacin-bound chromium 4 mg orally daily for 8 weeks decreases BMI and body weight when compared to baseline in overweight and obese adults. This product provided 400 mcg of elemental chromium and 100 mg of gymnemic acids (42604). It is unclear if these effects are due to gymnema, other ingredients, or the combination. More evidence is needed to rate gymnema for these uses.

• Diabetes. Clinical research shows that drinking jambolan tea 2 grams, prepared with jambolan leaves in one liter of water, does not improve fasting blood glucose in patients with type 2 diabetes when compared with placebo (13092). Clinical research in patients with prediabetes and those with newly-diagnosed type 2 diabetes shows that taking a combination product (GlycaCare-II, Sami-Sabinsa Group Ltd.) providing jambolan dried fruit extract 20 mg orally twice daily for 120 days is associated with similar decreases in glycated hemoglobin levels, and fasting and postprandial glucose levels, to metformin orally 500 mg twice daily. The combination product also contains cassia cinnamon bark extract, bitter melon fruit extract, heartwood extract, gymnema leaf extract, and Salacia bark extract (112762). It is not clear whether the changes are due to jambolan, other ingredients, or the combination. The validity of the results is also reduced by compliance issues and the lack of a per-protocol analysis.
• Venous leg ulcers. Clinical research in patients with venous leg ulcers shows that applying hydrocolloid gel dressings containing an extract of jambolan flowers, seeds, and bark for about 6 months does not improve the overall healing rate or speed of healing when compared with the hydrocolloid dressing alone (112763). More evidence is needed to rate jambolan for these uses.

• Dental plaque. Topical neem mouth rinses and gel extracts may reduce dental plaque. It is unclear if neem is as effective as chlorhexidine for this purpose. Details: Clinical research shows that using neem topically as a mouth rinse or gel extract twice daily for 3 weeks to 3 months can reduce dental plaque in some patients (12824,64845,94567,97926,104182). Neem leaf extracts, including one at a concentration of 2.5%, have been applied to the teeth and gums twice daily for up to 3 months (12824,64845,104182). Rinsing with 5 mL of neem solution (concentration unknown) or 15 mL of neem 2% solution twice daily for up to 30 days has also been used (94567,97926). It is unclear how neem compares to chlorhexidine for this purpose. One small clinical trial shows that applying neem gel shows similar improvements in plaque index when compared with chlorhexidine 0.2% gel (104182), while another small study shows that rinsing with a neem solution may not be as effective as chlorhexidine 0.2% solution for reducing dental plaque (97926). Reasons for these disparate findings are unclear, but may be related to differences in patient populations, formulations used, and study length.
• Gingivitis. Topical neem mouth rinses and gel extracts may reduce gingivitis, but neem may not be effective in patients with chronic gingivitis. It is unclear if neem is as effective as chlorhexidine for this purpose. Details: Clinical research shows that using neem topically as a mouth rinse or gel extract twice daily for 3 weeks to 3 months appears to improve gingivitis in some patients (12824,64845,94567,104182). However, neem may not be effective in patients with chronic gingivitis (64850). Neem leaf extracts, including one at a concentration of 2.5%, have been applied to the teeth and gums twice daily for up to 3 months (12824,64845,104182). Rinsing with 15 mL of neem 2% solution twice daily for 3 weeks has also been used (94567). It is unclear how neem compares to chlorhexidine for this purpose. One small clinical trial shows that applying neem gel shows similar improvements in gingival index when compared with chlorhexidine 0.2% gel (104182), while other small studies show that rinsing with neem solution may not be as effective as chlorhexidine 0.2% solution for reducing gingivitis (97926,97927). Reasons for these disparate findings are unclear, but may be related to differences in patient populations, formulations used, and study length.
• Lice. Topical neem extract shampoo may treat lice in children. Details: Clinical research in children 2-11 years of age with head lice shows that applying a single application of neem extract shampoo (Licener Pronovo Laboratories) 100 mL to dry hair for 10 minutes followed by rinsing with warm water eradicates 100% of head lice. A single application of neem extract shampoo appears to be slightly more effective than dimethicone (silicone oil) shampoo (97928).

• Acne. Topical neem extract has only been evaluated in combination with other ingredients; its effect when used alone is unclear. Details: An observational study in adults who have mild to moderate acne or those without current lesions who are prone to acne, shows that using a specific face wash containing unknown amounts of neem extract and turmeric extract (Himalaya's Purifying Neem Face Wash; Himalaya Drug Company) twice daily for 28 days reduces new inflammatory and non-inflammatory acne lesions by 45% and 69%, respectively, when compared with baseline (107883). The validity of these findings is limited by the lack of a comparator group and short duration of treatment; additionally, it is unclear if this effect is due to neem extract, other ingredients, or the combination.
• Abortion. Although there has been interest in using oral neem to induce abortion, there is insufficient reliable information available about the clinical effects of neem for this purpose.
• Asthma. Although there has been interest in using oral neem for asthma, there is insufficient reliable information available about the clinical effects of neem for this purpose.
• Cardiovascular disease (CVD). Although there has been interest in using oral neem for CVD, there is insufficient reliable information available about the clinical effects of neem for this purpose.
• Contraception. Although there has been interest in using oral and intravaginal neem for contraception, there is insufficient reliable information available about the clinical effects of neem for this purpose.
• Coronavirus disease 2019 (COVID-19). There is limited evidence on the oral use of a neem leaf extract in preventing COVID-19 in high-risk individuals. Details: A clinical study in adults at high risk for COVID-19 infection (e.g. healthcare workers and relatives of patients with COVID-19) shows that taking a specific capsule formulation of neem leaf extract (Nisarga's Neem; Nisarga Biotech) 50 mg twice daily for 28 days decreases the rate of COVID-19 infections by day 29 to 4%, compared with 10% of patients in the placebo group. This suggests that 17 patients would need to take this product to prevent one infection (107882). The validity of this study is limited by the short duration of treatment and unclear reporting. Additionally, patients were only tested for COVID-19 at baseline, day 29, or if symptoms were present; therefore, asymptomatic COVID-19 infections may have been underreported.
• Cough. Although there has been interest in using oral neem for cough, there is insufficient reliable information available about the clinical effects of neem for this purpose.
• Diabetes. It is unclear if oral neem extract is beneficial in patients with diabetes. Details: One small clinical trial in patients with type 2 diabetes who are taking metformin shows that taking a specific neem leaf and twig extract (PhytoBGS; Natreon Inc) 125 mg, 250 mg, or 500 mg twice daily for 12 weeks improves glycemic control in a dose-dependent manner. When compared with placebo, reductions in fasting plasma glucose with neem extract ranged from 8-22 mg/dL and reductions in glycated hemoglobin ranged from 0.18% to 1.47%. Postprandial glucose and measures of insulin resistance and endothelial function were also improved (104181).
• Dyspepsia. Although there has been interest in using oral neem for dyspepsia, there is insufficient reliable information available about the clinical effects of neem for this purpose.
• Hemorrhoids. Although there has been interest in using topical neem for hemorrhoids, there is insufficient reliable information available about the clinical effects of neem for this purpose.
• Insect repellent. Although there has been interest in using topical neem as an insect repellent, there is insufficient reliable information available about the clinical effects of neem for this purpose.
• Intestinal parasite infection. Although there has been interest in using oral neem for intestinal parasite infections, there is insufficient reliable information available about the clinical effects of neem for this purpose.
• Metabolic syndrome. It is unclear if oral neem leaf and twig extract is beneficial in patients with metabolic syndrome. Details: One clinical trial in patients with metabolic syndrome shows that taking a specific neem leaf and twig extract (PhytoBGS; Natreon Inc) 250 mg or 500 mg twice daily for 12 weeks improves glycemic control in a dose-dependent manner when compared with placebo. In the treatment group, reductions in fasting plasma glucose, postprandial plasma glucose, and glycated hemoglobin (HbA1c) ranged from 3-6 mg/dL, 0.7-5.4 mg/dL, and 0.6% to 1.7%, respectively (107881). However, there was no improvement in lipid parameters, and a lower dose of 125 mg twice daily did not affect any measurements (107881). The validity of this study is limited due to unclear reporting.
• Mosquito repellent. Small clinical studies suggest that topical creams containing neem oil may provide moderate to high-level protection against mosquitos. Details: Several small clinical studies show that topical application of a cream containing neem oil 1%, 2%, or 5% provides 37.5% to 100% protection against mosquitoes when compared with a placebo cream. Effectiveness seems to vary depending on mosquito species and geographic location (64876,64878,64882).
• Osteoarthritis. Although there has been interest in using topical neem for osteoarthritis, there is insufficient reliable information available about the clinical effects of neem for this condition.
• Peptic ulcers. It is unclear if oral neem is beneficial in patients with peptic ulcers. Details: One small, uncontrolled clinical study in six patients with peptic ulcers shows that taking neem bark extract 30-60 mg twice daily for 10 weeks reduces gastric secretions when compared to baseline and might aid in the healing of gastroduodenal ulcers. All patients treated with neem bark extract experienced at least 80% healing of gastroduodenal ulcers (12822). The validity of these findings is limited by the very small study size and the lack of a control group.
• Psoriasis. It is unclear if oral neem is beneficial in patients with psoriasis. Details: One small clinical trial in patients with uncomplicated psoriasis shows that taking neem extract by mouth daily in combination with daily sun exposure and application of a Vaseline-based cream containing crude coal tar and salicylic acid for 12 weeks reduces psoriasis symptom severity by approximately 50% when compared with placebo (64892).
• Scleroderma. Topical neem has only been evaluated in combination with other ingredients; its effect when used alone is unclear. Details: Observational research in patients with systemic sclerosis has found that topical application of a specific cream (Holoil, RI.MOS. SRL) containing neem oil and St. John's wort extract seems to improve the healing of skin ulcers, decrease pain, reduce the need for surgical removal of lesions, and reduce the risk of infections and need for antibiotic therapy when compared with a control group (102867). It is unknown if these effects are due to neem, St. John's wort, or the combination. Additionally, the validity of these results is limited by a lack of randomization, blinding, and placebo-control.
• Tungiasis. It is unclear if topical neem oil is beneficial for the treatment of tungiasis. Details: One small clinical trial in children aged 6-15 years with tungiasis shows that topical application of an oil mixture containing neem seed oil 20% and virgin coconut oil 80%, 1 drop on days 1 and 3, kills about 40% of sand fleas within 7 days, a rate similar to standard treatment with a potassium permanganate 0.05% foot bath (104258).
• Urinary tract infections (UTIs). Although there has been interest in using oral neem for UTIs, there is insufficient reliable information available about the clinical effects of neem for this purpose.
• Wound healing. Topical neem has only been evaluated in combination with other ingredients; its effect when used alone is unclear. Details: A moderate-size clinical study in adults with dehisced post-surgical wounds shows that applying a specific aerosol product (1PWD, Kerecis AG) containing neem oil and St. John's wort to wounds during dressing changes does not improve wound healing scores at day 28 but may reduce pain scores when compared with silver-based dressings (alginates or polyurethane foam) (111592). However, this study may have been inadequately powered to detect a difference between groups. It is also unclear if these affects are due to neem, St. John's wort, or the combination. More evidence is needed to rate neem for these uses.

• Diabetes. Oral Tinospora cordifolia seems to reduce glycated hemoglobin and fasting blood glucose in adults with type 2 diabetes. Details: A meta-analysis of 2 moderate-sized clinical trials in adults with type 2 diabetes shows that taking Tinospora cordifolia extract 500 mg or 1500 mg daily for 9 or 26 weeks, respectively, reduces glycated hemoglobin by 0.5% when compared with no additional medicine. Additionally, meta-analysis of 2 small to moderate-sized clinical trials in adults with type 2 diabetes shows that taking Tinospora cordifolia extract 1500 mg daily for 26 weeks as tablets or as a decoction 5 mL daily for 9 weeks reduces fasting blood glucose by 4 mg/dL when compared with placebo or no additional medicine (111503). However, all studies were conducted in India; it is unclear if these findings can be extrapolated to other geographic locations.

INSUFFICIENT RELIABLE EVIDENCE to RATE

• Allergic rhinitis (hay fever). It is unclear if oral Tinospora cordifolia extract is beneficial in patients with allergic rhinitis. Details: One small clinical trial in patients with allergic rhinitis shows that taking a specific Tinospora cordifolia aqueous stem extract (Tinofend, Verdure Sciences) 300 mg three times daily for 8 weeks decreases sneezing, as well as nasal itching, discharge, and obstruction, when compared with placebo (15085).
• Asthma. Although there has been interest in using oral Tinospora cordifolia for asthma, there is insufficient reliable information about the clinical effects of Tinospora cordifolia for this purpose.
• Athletic performance. It is unclear if oral Tinospora cordifolia extract is effective for improving athletic performance. Details: One small clinical study in healthy males shows that taking Tinospora cordifolia stem powdered extract 150-300 mg daily for 28 days improves speed during cycling and hand grip strength when compared to baseline; however, these improvements are not significant when compared with placebo (92230).
• Cancer. Although there has been interest in using oral Tinospora cordifolia for cancer, there is insufficient reliable information about the clinical effects of Tinospora cordifolia for this purpose.
• Coronavirus disease 2019 (COVID-19). Although there has been interest in using oral Tinospora cordifolia for COVID-19, there is insufficient reliable information about the clinical effects of Tinospora cordifolia for this purpose.
• Diabetic foot ulcers. It is unclear if oral Tinospora cordifolia is beneficial in patients with diabetic foot ulcers. Details: One small clinical study in patients with diabetic foot ulcers shows that taking Tinospora cordifolia extract (dose unknown), in conjunction with standard treatment, for one month reduces the total number of debridements by 24% and the extent of phagocytosis in the wound when compared with placebo plus standard treatment. However, Tinospora cordifolia does not appear to improve the wound severity, size, or depth when compared with placebo (92227).
• Gout. Although there has been interest in using oral Tinospora cordifolia for gout, there is insufficient reliable information about the clinical effects of Tinospora cordifolia for this purpose.
• Hepatitis. Although there has been interest in using oral Tinospora cordifolia for hepatitis, there is insufficient reliable information about the clinical effects of Tinospora cordifolia for this purpose.
• Hyperlipidemia. Although there has been interest in using oral Tinospora cordifolia for hyperlipidemia, there is insufficient reliable information about the clinical effects of Tinospora cordifolia for this purpose.
• Hypertriglyceridemia. It is unclear if oral Tinospora cordifolia extract is beneficial in patients with hypertriglyceridemia. Details: One small clinical study in patients with hypertriglyceridemia shows that taking Tinospora cordifolia stem extract 3 grams daily for 14 days reduces levels of triglycerides and low-density lipoprotein (LDL) cholesterol by around 170 mg/dL and 25 mg/dL, respectively, while increasing high-density lipoprotein (HDL) cholesterol levels by 12 mg/dL when compared to baseline. Patients in a control group taking metformin saw smaller improvements in these lipid levels, although a statistical comparison between Tinospora cordifolia and metformin was not reported (106846).
• Osteoarthritis. Oral Tinospora cordifolia has only been evaluated in combination with other ingredients; its effect when used alone is unclear. Details: A large clinical study in adults with osteoarthritis shows that taking a specific Ayurvedic formulation (shunthi-guduchi) containing Tinospora cordifolia 440 mg, Indian gooseberry 1000 mg, and ginger 200 mg, with or without Boswellia serrata 600 mg, in divided doses daily for 24 weeks improves pain and functionality as effectively as celecoxib or glucosamine sulfate (89557). However, the clinical validity of these results is limited by the lack of a placebo control. Also, it is unclear if these findings are due to Tinospora cordifolia, other ingredients, or the combination.
• Peptic ulcers. Although there has been interest in using oral Tinospora cordifolia for peptic ulcers, there is insufficient reliable information about the clinical effects of Tinospora cordifolia for this purpose.
• Rheumatoid arthritis (RA). Although there has been interest in using oral Tinospora cordifolia for RA, there is insufficient reliable information about the clinical effects of Tinospora cordifolia for this purpose.
• Scabies. It is unclear if topical Tinospora cordifolia lotion is beneficial in patients with scabies. Details: One small clinical study in children and young adults shows that topical application of Tinospora cordifolia lotion 3 days weekly for 2 weeks is as effective as permethrin 5% lotion for clearing the symptoms of scabies. At 28 days from the initiation of treatment, complete cure occurs in 70% of patients applying Tinospora cordifolia, compared with 50% of patients applying permethrin (92220).
• Sexual desire. Although there has been interest in using oral Tinospora cordifolia for increasing sexual desire, there is insufficient reliable information about the clinical effects of Tinospora cordifolia for this purpose. More evidence is needed to rate Tinospora cordifolia for these uses.

PREGNANCY: LIKELY UNSAFE
when used orally in amounts greater than those found in food. Fenugreek has potential oxytoxic and uterine stimulant activity (12531). There are case reports of congenital malformations, including hydrocephalus, anencephaly, cleft palate, and spina bifida, after consumption of fenugreek seeds during pregnancy (96068). Consumption of fenugreek immediately prior to delivery may cause the neonate to have unusual body odor. Although this does not appear to cause long-term sequelae, it may be misdiagnosed as maple syrup urine disease (9781,96068).

LACTATION: POSSIBLY SAFE
when used orally to stimulate lactation, short-term. Although most available clinical studies lack safety testing in the lactating parent or infant (12535,22569,22570), some evidence suggests that taking fenugreek 1725 mg three times daily orally for 21 days does not cause negative side effects in the infant (90115).

ANTIDIABETES DRUGS Interaction Rating = Moderate Be cautious with this combination. Severity = Moderate •  Occurrence = Probable •  Level of Evidence = B Taking bitter melon with antidiabetes drugs might increase the risk of hypoglycemia.  Details Bitter melon can lower blood glucose levels and might have additive effects when used with antidiabetes drugs (34,35,36,38,8181,12530,92124,92126,92129,100632,111503). This might increase the risk of hypoglycemia in some patients. Monitor blood glucose levels closely.

P-GLYCOPROTEIN SUBSTRATES Interaction Rating = Moderate Be cautious with this combination. Severity = Moderate •  Occurrence = Possible •  Level of Evidence = D Theoretically, bitter melon might increase levels of P-glycoprotein substrates.  Details Bitter melon might inhibit the p-glycoprotein (P-gp) intestinal pump and increase intracellular levels of P-gp substrates. In vitro research in intestinal cells shows that 1-monopalmitin, a constituent of bitter melon, increases levels of daunomycin, a P-gp substrate (97509). Additionally, drinking bitter melon juice has been associated with a case of acute pancreatitis in a patient who had been taking pazopanib, a P-gp substrate, for 8 years. Researchers theorize that inhibition of P-gp led to increased levels of pazopanib, resulting in pazopanib-induced pancreatitis (109581).

PAZOPANIB (Votrient) Interaction Rating = Moderate Be cautious with this combination. Severity = Moderate •  Occurrence = Possible •  Level of Evidence = D Theoretically, bitter melon might increase levels of pazopanib, potentially increasing the risk of adverse effects.  Details In one case, a 65-year-old patient taking pazopanib for 8 years for renal cell carcinoma experienced signs and symptoms consistent with acute pancreatitis 4 days after drinking bitter melon juice at a dose of 100-150 mL daily. The patient's symptoms, amylase levels, and lipase levels improved upon discontinuation of bitter melon and pazopanib. Pazopanib treatment was re-initiated with no further evidence of pancreatitis. Researchers theorize that inhibition of P-glycoprotein by bitter melon led to increased levels of pazopanib, a P-glycoprotein substrate, resulting in pazopanib-induced pancreatitis (109581).

ANTICOAGULANT/ANTIPLATELET DRUGS Interaction Rating = Moderate Be cautious with this combination. Severity = High •  Occurrence = Unlikely •  Level of Evidence = B Theoretically, fenugreek might have additive effects when used with anticoagulant or antiplatelet drugs.  Details Some of the constituents in fenugreek have antiplatelet effects in animal and in vitro research. However, common fenugreek products might not contain sufficient concentrations of these constituents for clinical effects. A clinical study in patients with coronary artery disease or diabetes shows that taking fenugreek seed powder 2.5 grams twice daily for 3 months does not affect platelet aggregation, fibrinolytic activity, or fibrinogen levels (5191,7389,49643).

ANTIDIABETES DRUGS Interaction Rating = Moderate Be cautious with this combination. Severity = Moderate •  Occurrence = Probable •  Level of Evidence = B Theoretically, fenugreek seed might have additive hypoglycemic effects when used with antidiabetes drugs.  Details Clinical research shows that fenugreek seed can reduce fasting blood glucose and 2-hour postprandial glucose levels in adults with type 2 diabetes (10284,90112,96065,105016).

CLOPIDOGREL (Plavix) Interaction Rating = Moderate Be cautious with this combination. Severity = Moderate •  Occurrence = Possible •  Level of Evidence = D Theoretically, fenugreek seed might alter the clinical effects of clopidogrel by inhibiting its conversion to the active form.  Details Animal research shows that fenugreek seed 200 mg/kg daily for 14 days increases the maximum serum concentration of clopidogrel by 21%. It is unclear how this affects the pharmacokinetics of the active metabolite of clopidogrel; however, this study found that concomitant use of fenugreek seed and clopidogrel prolonged bleeding time by an additional 11% (108701).

METOPROLOL (Toprol) Interaction Rating = Moderate Be cautious with this combination. Severity = Moderate •  Occurrence = Probable •  Level of Evidence = B Theoretically, fenugreek seed might have additive hypotensive effects when used with metoprolol.  Details Animal research shows that fenugreek seed 300 mg/kg daily for 2 weeks decreases systolic and diastolic blood pressure by 9% and 11%, respectively, when administered alone, and by 15% and 22%, respectively, when given with metoprolol 10 mg/kg (108703).

PHENYTOIN (Dilantin) Interaction Rating = Moderate Be cautious with this combination. Severity = Moderate •  Occurrence = Possible •  Level of Evidence = D Theoretically, fenugreek might decrease plasma levels of phenytoin.  Details Animal research shows that taking fenugreek seeds for 1 week decreases maximum concentrations and the area under the curve of a single dose of phenytoin by 44% and 72%, respectively. This seems to be related to increased clearance (110905). So far, this interaction has not been reported in humans.

SILDENAFIL (Viagra) Interaction Rating = Moderate Be cautious with this combination. Severity = Moderate •  Occurrence = Possible •  Level of Evidence = D Theoretically, concurrent use of sildenafil and fenugreek might reduce levels and therapeutic effects of sildenafil.  Details Animal research shows that taking fenugreek seeds for 1 week reduces maximum concentrations and the area under the curve of a single dose of sildenafil by 27% and 48%, respectively (110898). So far, this interaction has not been reported in humans.

THEOPHYLLINE Interaction Rating = Moderate Be cautious with this combination. Severity = Moderate •  Occurrence = Possible •  Level of Evidence = D Theoretically, fenugreek may reduce the levels and clinical effects of theophylline.  Details Animal research shows that fenugreek 50 grams daily for 7 days reduces the maximum serum concentration (Cmax) of theophylline by 28% and the area under the plasma drug concentration-time curve (AUC) by 22% (90118).

WARFARIN (Coumadin) Interaction Rating = Moderate Be cautious with this combination. Severity = High •  Occurrence = Possible •  Level of Evidence = D Theoretically, fenugreek might have additive effects with warfarin and increase the international normalized ratio (INR).  Details Some fenugreek constituents have antiplatelet effects, although these might not be present in concentrations that are clinically significant (7389). In one case report, a patient taking warfarin experienced an increased INR when starting to take fenugreek in combination with boldo (5191).

ANTIDIABETES DRUGS Interaction Rating = Moderate Be cautious with this combination. Severity = Moderate •  Occurrence = Probable •  Level of Evidence = B Theoretically, taking gymnema with antidiabetes drugs might increase the risk of hypoglycemia.  Details Gymnema reduces blood glucose levels in some human and animal research. In human studies, it has been shown to enhance the blood glucose lowering effects of hypoglycemic drugs (45,46,92119,92121,92123). However, other research in adults with prediabetes or metabolic syndrome suggests that gymnema does not reduce fasting levels of blood glucose (96235,105346). Until more is known, monitor blood glucose levels closely.

CYTOCHROME P450 1A2 (CYP1A2) SUBSTRATES Interaction Rating = Moderate Be cautious with this combination. Severity = Moderate •  Occurrence = Possible •  Level of Evidence = D Theoretically, gymnema might increase levels of drugs metabolized by CYP1A2.  Details Animal and in vitro research shows that gymnema can inhibit the CYP1A2 enzyme (96236,96237,96238). In one animal study, oral administration of gymnema for 7 days increased the plasma concentrations of phenacetin, a CYP1A2 substrate, by about 1.4-fold and reduced the clearance of phenacetin by about 29% (96237).

CYTOCHROME P450 2C9 (CYP2C9) SUBSTRATES Interaction Rating = Moderate Be cautious with this combination. Severity = Moderate •  Occurrence = Possible •  Level of Evidence = D Theoretically, gymnema might increase or decrease levels of drugs metabolized by CYP2C9.  Details Animal research shows that gymnema can induce the CYP2C9 enzyme. In one animal study, gymnema caused a 2.4-fold increase in the clearance of tolbutamide, a CYP2C9 substrate, in rats (96237). In vitro research also shows that gymnema can inhibit CYP2C9 (96236,96238).

CYTOCHROME P450 3A4 (CYP3A4) SUBSTRATES Interaction Rating = Minor Be watchful with this combination. Severity = Moderate •  Occurrence = Unlikely •  Level of Evidence = D Theoretically, gymnema might increase levels of drugs metabolized by CYP3A4.  Details One in vitro study using rat liver microsomes shows that gymnema can modestly inhibit the CYP3A4 enzyme (96238). However, other in vitro research using human liver microsomes shows that gymnema does not affect CYP3A4 activity (96236). Animal research also shows that gymnema does not alter the function of CYP3A4.

Most Common Adverse Effects:
Orally: Abdominal pain, bloating, diarrhea, dyspepsia, flatulence, hypoglycemia, and nausea.
Serious Adverse Effects (Rare):
All ROA: Severe allergic reactions including angioedema, bronchospasm, and shock.

Endocrine ...Orally, large doses of fenugreek seed, 100 grams daily of defatted powder, have caused hypoglycemia (164,96068).

Gastrointestinal ...Orally, fenugreek seed can cause mild gastrointestinal symptoms, such as diarrhea, dyspepsia, abdominal distention and pain, nausea, and flatulence, especially when taken on an empty stomach (622,12534,18349,93421,96065,96068,105016).

Immunologic ...Fenugreek can cause allergic reactions when used orally and topically, and when the powder is inhaled (719,96068). Orally, fenugreek has caused bronchospasm, diarrhea, and itching, and skin reactions severe enough to require intravenous human immunoglobulin (96068). Topically, fenugreek paste has resulted in facial swelling, wheezing, and numbness around the head (719,96068). When used both orally and topically by a single individual, asthma and rhinitis occurred (96068). Inhalation of fenugreek powder has resulted in fainting, sneezing, runny nose, and eye tearing (719,96068).

A single intrauterine instillation of purified neem oil has been reported to cause mild transient eosinophilia in healthy, tubectomised females (64886).

Hepatic ...Orally, neem oil has been associated with reports of hepatotoxicity in infants and children. These adverse effects occurred after single doses of neem oil ranging from a few drops to 60 mL. Pathologic findings on liver biopsy reports have been consistent with Reye-like syndrome (3473,3474,3475).

Immunologic ...Topically, a case of aggravated bullous pemphigoid requiring hospitalization is reported in a 47-year-old patient with this autoimmune condition after application of neem oil to blisters for an unknown duration (111715).

Neurologic/CNS ...Orally, single doses of neem oil ranging from a few drops to 60 mL have been associated with reports of encephalopathy in infants and small children. Symptoms include drowsiness, seizure, loss of consciousness, coma, cerebral edema, Reye-like syndrome, and death within hours of ingestion (3473,3474,3476,3476,64855,94750). There is also at least one case report of neurotoxicity in an adult after ingestion of a neem-based pesticide. A 35-year-old female experienced neurotoxicity requiring intensive medical care and ventilation after ingestion of a pesticide containing azadirachtin, a constituent of neem oil (64858).

Ocular/Otic ...In one case report, a 35-year-old female developed toxic optic neuropathy and vision loss in both eyes lasting for two days after consuming 150 mL of neem oil in a suicide attempt five days earlier (64856).

Renal ...Orally, neem leaf has been reported to cause oliguria, anuria, acute tubular necrosis, and nephrotoxicity in adults (12833,12834).

General ...Orally, Tinospora cordifolia seems to be well tolerated. Topically, a thorough evaluation of safety outcomes has not been conducted.
Most Common Adverse Effects:
Orally: Headache and nasal pain.
Topically: Burning, erythema, and pruritus.
Serious Adverse Effects (Rare):
Orally: Liver injury has been reported.

Dermatologic ...Topically, Tinospora cordifolia has been reported to cause pruritus, erythema, and burning (92220).

Hepatic ...Orally, liver injury is reported after consumption of Tinospora cordifolia. In 2 case series, autoimmune hepatitis, acute hepatitis, worsening of chronic liver disease, or acute liver failure is reported in 49 patients after consuming various forms and doses of Tinospora cordifolia alone or in combination with other ingredients for a median of 42-90 days. Of these patients, 2 required a liver transplant and 4 died (110533,110534).
Liver injury is also reported in patients taking combination supplements containing Tinospora cordifolia. One case reports a 50-year-old female who presented with a 2-week history of constant right upper quadrant abdominal pain, nausea, loss of appetite, and fatigue, along with severely elevated alanine transaminase (ALT) and aspartate aminotransferase (AST), after taking a specific combination product containing Tinospora cordifolia 900 mg, stinging nettle 600 mg, and quercetin 600 mg (HistaEze) daily for 4 to 5 weeks (112404). Another case reports a 54-year-old female who developed acute hepatitis with elevated ALT, AST, alkaline phosphatase, gamma-glutamyl transferase, and bilirubin after consuming a multi-ingredient product containing approximately 1900 mg of Tinospora cordifolia and 11 other Ayurvedic herbals daily for 2.5 months (112405). In both cases, liver function returned to normal within 3 months of discontinuing the supplement (112404,112405). It is unclear whether the liver injury in these cases is due to Tinospora cordifolia, other ingredients, or the combination.

Neurologic/CNS ...Orally, Tinospora cordifolia has been reported to cause headache in a clinical trial (15085).

Pulmonary/Respiratory ...Orally, Tinospora cordifolia extract has been reported to cause nasal pain in a clinical trial (15085).
