• Asthma. Oral anise has only been evaluated in combination with other ingredients; its effect when used alone is unclear. Details: A small clinical study in adults with allergic asthma shows that drinking one cup of tea prepared with multiple ingredients, including anise, twice daily for 6 months reduces sleep discomfort, cough frequency, and cough intensity when compared with placebo (19056). It is unclear if these findings are due to anise, other ingredients, or the combination.
• Constipation. Oral anise has only been evaluated in combination with other ingredients; its effect when used alone is unclear. Details: A very small crossover trial in patients with constipation shows that taking an herbal tea containing a combination of anise, fennel, elderberry, and senna daily for 5 days can decrease colon transit time, increase the number of daily evacuations, and improve the perception of bowel function when compared with placebo (49494). It is unclear if these findings are due to anise, other ingredients, or the combination.
• Depression. It is unclear if oral anise oil is beneficial in patients with depression. Details: A small clinical study in adults with mild to moderate depression and irritable bowel syndrome (IBS) shows that taking enteric-coated anise oil 200 mg three times daily for 4 weeks improves symptoms of depression by an additional 28% when compared with placebo and an additional 32% when compared with peppermint (94947).
• Diabetes. It is unclear if oral anise seed powder is beneficial in patients with diabetes. Details: A small clinical study in adults with type 2 diabetes shows that taking anise seed powder 5 grams daily for 60 days decreases fasting blood glucose levels by 36%, total cholesterol levels by 7.5%, and triglyceride levels by 15% when compared to baseline. Fasting blood glucose significantly increased in the control group, and total cholesterol and triglyceride levels were relatively unchanged (94953).
• Dysmenorrhea. Although there has been interest in using oral anise for dysmenorrhea, there is insufficient reliable information about the clinical effects of anise for this purpose.
• Dyspepsia. It is unclear if oral anise powder is beneficial in patients with dyspepsia. Details: A small clinical study in adults with postprandial distress syndrome shows that taking anise powder 3 grams three times daily for 4 weeks improves quality of life and symptoms of functional dyspepsia when compared with placebo. Of the evaluated symptoms, improvement was seen in all categories when compared to placebo except for nausea and vomiting, which were present in less than 5% of patients at baseline (94944,94945).
• Irritable bowel syndrome (IBS). It is unclear if oral anise oil is beneficial inpatients with IBS. Details: A small clinical study in adults with IBS shows that taking enteric-coated anise oil 200 mg three times daily for 4 weeks eliminates IBS symptoms in 75% of patients, compared with 53% of patients taking peppermint oil and 35% taking placebo. The greatest symptom improvement occurred with abdominal pain, bloating, and reflux, and was maintained for an additional 2 weeks after treatment completion (94946).
• Lactation. It is unclear if oral anise tea is beneficial for increasing human milk production. Details: A moderate-sized clinical study in post-partum adults shows that drinking a tea containing anise 2 grams and black tea 1 gram 3 times daily with meals for 7 days increases the volume of pumped human milk on day 7 by an average of 98 mL and 113 mL, respectively, when compared with a placebo of black tea 3 grams daily and when compared with a control group not assigned to any tea or galactagogues (112863).
• Lice. Topical anise has only been evaluated in combination with other ingredients; its effect when used alone is unclear. Details: A small clinical study in children 6-14 years of age shows that application of a topical spray containing anise oil, coconut oil, and ylang ylang oil three times at 5-day intervals is 92% effective for the treatment of head lice and seems to be comparable in effectiveness to a spray containing permethrin, malathion, piperonyl butoxide, and isododecane (13483).
• Menopausal symptoms. It is unclear if oral anise seed extract is beneficial in patients with menopausal symptoms. Details: A small clinical study in postmenopausal adults shows that taking anise seed extract 330 mg three times daily for 4 weeks reduces the frequency and severity of hot flashes by approximately 75% when compared with placebo (94948).
• Migraine headache. It is unclear if topical anise essential oil is beneficial in patients with migraine headache. Details: A small clinical study in adults with migraine headache shows that applying 2 mL of a cream containing anise essential oil 7% to the temporal and forehead zones at the onset of a migraine reduces the impact of the headache by approximately 10% when compared with a control cream. However, there was no effect of the anise cream on analgesic use or average headache severity when compared with placebo cream. Additionally, due to the strong smell of the anise cream, patient blinding may have been compromised (100166).
• Premenstrual syndrome (PMS). It is unclear if oral anise extract is beneficial in patients with PMS. Details: A small clinical study in female college students with PMS shows that taking anise extract 110 mg three times daily, starting 7 days before menstruation and ending 3 days after, improves concentration, mood, irritability, sleep, food cravings, and other symptoms of PMS, as measured using the Premenstrual Symptoms Screening Tool, when compared with placebo (103875). More evidence is needed to rate anise for these uses.

• Anxiety. Although there is interest in using oral Asparagus racemosus for anxiety, there is insufficient reliable information about the clinical effects of Asparagus racemosus for this condition.
• Athletic performance. It is unclear if oral Asparagus racemosus is beneficial for improving athletic performance. Details: In recreationally trained males, taking Asparagus racemosus 500 mg daily for 8 weeks during bench press training increases the number of repetitions before exhaustion, and allows a greater increase in training loads, when compared with placebo (106413).
• Bronchitis. Although there is interest in using oral Asparagus racemosus for bronchitis, there is insufficient reliable information about the clinical effects of Asparagus racemosus for this condition.
• Cancer. Although there is interest in using oral Asparagus racemosus for cancer, there is insufficient reliable information about the clinical effects of Asparagus racemosus for this purpose.
• Dementia. Although there is interest in using oral Asparagus racemosus for dementia, there is insufficient reliable information about the clinical effects of Asparagus racemosus for this condition.
• Diabetes. Although there is interest in using oral Asparagus racemosus for diabetes, there is insufficient reliable information about the clinical effects of Asparagus racemosus for this condition.
• HIV/AIDS. Although there is interest in using oral Asparagus racemosus for HIV/AIDS, there is insufficient reliable information about the clinical effects of Asparagus racemosus for this condition.
• Lactation. Oral Asparagus racemosus has only been evaluated in combination with other ingredients; its effect when used alone is unclear. Details: In mothers who have to supplement their breast milk or who have infants with below normal weight gain, taking an herbal mixture containing Asparagus racemosus as 2 teaspoons twice daily for 4 weeks does not increase breast milk production, infant weight gain velocity, or prolactin levels (32588). Per 100 grams, the herbal mixture contained Asparagus racemosus 15 grams, dill 1 gram, morning glory 1 gram, licorice 2.5 grams, cumin 0.5 grams, and panchatrinamol 1 gram. Another small clinical study in postpartum mothers in India shows that consuming Asparagus racemosus in the form of 1 daily granola bar that contains Asparagus racemosus and other ingredients (Shavari Bar, Act Life Sciences Ltd.) for 4 days starting the day after delivery increases breast milk volume by about 15 mL and shortens the time to breast fullness when compared with placebo (111721). However, it is unclear whether any improvement is clinically significant, especially in the longer term. Additionally, the dose of Asparagus racemosus was not specified which limits the interpretation of these results.
• Muscle strength. It is unclear if oral Asparagus racemosus is beneficial for improving muscle strength. Details: A very small clinical study in physically active postmenopausal patients shows that taking Asparagus racemosus 1000 mg daily for 6 weeks improves hand grip strength, but not knee extensor strength, when compared with placebo (110736).
• Sexual desire. Although there is interest in using oral Asparagus racemosus for sexual desire, there is insufficient reliable information about the clinical effects of Asparagus racemosus for this purpose.
• Tuberculosis. Although there is interest in using oral Asparagus racemosus for tuberculosis, there is insufficient reliable information about the clinical effects of Asparagus racemosus for this condition. More evidence is needed to rate Asparagus racemosus 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.

• ACE inhibitor-induced cough. It is unclear if oral marshmallow root is beneficial in patients with cough due to ACE inhibitors. Details: A small clinical study in patients with ACE inhibitor-induced cough shows that taking marshmallow root 40 mg (20 drops) three times daily for 4 weeks improves cough when compared to baseline (62027). The validity of this finding is limited by the lack of a control group.
• Atopic dermatitis (eczema). It is unclear if topical marshmallow is beneficial in children with eczema. Details: A very small clinical study in children ages 3 months to 12 years with a recent diagnosis of mild to moderate eczema shows that applying a marshmallow 1% ointment twice daily for 1 week and then three times weekly for 3 weeks seems to reduce symptoms, as measured on the SCORing Atopic Dermatitis (SCORAD) scale, when compared with applying hydrocortisone 1% ointment (105437). This finding is limited by the large number of drop-outs due to non-compliance, most of which were in the marshmallow group.
• Breast engorgement. It is unclear if topical marshmallow is beneficial in women with this condition. Details: A small clinical study in breastfeeding women with breast engorgement shows that applying a compress containing 40-50 mL of a solution made from marshmallow leaves and stems 3 times daily for 2 days in conjunction with standard treatment improves patient-reported breast engorgement scores when compared with standard treatment alone. Standard treatment consisted of massage and alternating warm and cold compresses before and after breastfeeding (92845).
• Constipation. Although there is interest in using oral marshmallow for constipation, there is insufficient reliable information about the clinical effects of marshmallow for this condition.
• Cough. Although there is interest in using oral marshmallow for cough, there is insufficient reliable information about the clinical effects of marshmallow for this condition.
• Diarrhea. Although there is interest in using oral marshmallow for diarrhea, there is insufficient reliable information about the clinical effects of marshmallow for this condition.
• Fever. It is unclear if topical marshmallow is beneficial for pediatric fever. Details: A moderate-sized clinical study in children aged 6 months-10 years with fever receiving rectal acetaminophen shows that applying marshmallow extract body wash and lukewarm water reduces the time to defervescence by 8 minutes when compared with lukewarm water alone, but does not improve the change in body temperature, number of acetaminophen doses given, or incidence of fever recurrence (112375). However, the interpretation of these findings is limited to patients without fevers greater than 40 degrees Celsius or history of febrile seizures since these patients were not studied.
• Leishmania lesions. Topical marshmallow has only been evaluated in combination with other ingredients; its effect when used alone is unclear. Details: Preliminary clinical research suggests that the topical application of an herbal extract containing a combination of marshmallow and Althaea rosa to affected areas for 5 days can help promote curing of Leishmania lesions (62020).
• Respiratory tract infections. Although there is interest in using oral marshmallow for respiratory tract infections, there is insufficient reliable information about the clinical effects of marshmallow for this condition.
• Vaginal candidiasis. It is unclear if vaginal marshmallow is beneficial for vulvovaginal candidiasis. Details: A small clinical study in adults with vulvovaginal candidiasis shows that applying a vaginal cream comprised of marshmallow extract 4% and clotrimazole 1% daily for 7 days improves itching, dyspareunia, and dysuria at 7 days when compared with clotrimazole 1% alone. At 30 days, the marshmallow intervention also results in fewer positive yeast cultures and sustained reduction in itching (112371). However, the validity of these results is limited by significant differences between groups at baseline for dyspareunia and dysuria, and lack of adjustment for multiple comparisons which can increase false positive findings. Additionally, all primary outcomes were patient-reported.
• Venous leg ulcers. Although there is interest in using topical marshmallow for venous leg ulcers, there is insufficient reliable information about the clinical effects of marshmallow for this condition.
• Wounds. Although there is interest in using topical marshmallow for wounds, there is insufficient reliable information about the clinical effects of marshmallow for this condition. More evidence is needed to rate marshmallow 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).
