POSSIBLY EFFECTIVE

• Dysmenorrhea. Taking fennel oil or extract by mouth may reduce pain in patients with primary dysmenorrhea. This benefit may be similar to ibuprofen or mefenamic acid. Details: Two separate meta-analyses in patients with primary dysmenorrhea show that taking fennel oil or fennel extract for 1-6 menstrual cycles reduces dysmenorrhea pain when compared with placebo. Improvement in pain was similar when compared with ibuprofen or mefenamic acid. In the included studies, doses of fennel oil ranged from 3-30 drops every 4-8 hours, and doses of fennel extract ranged from 30-230 mg daily (104196,108972). However, most studies included in these meta-analyses were small and low-quality, and all studies were conducted in Iran. Higher quality studies in other geographic locations are needed to confirm these findings.

• Anxiety. Although there has been interest in using oral fennel for anxiety, there is insufficient reliable information about the clinical effects of fennel for this purpose.
• Bronchitis. Although there has been interest in using oral fennel for bronchitis, there is insufficient reliable information about the clinical effects of fennel for this purpose.
• Cancer. Although there has been interest in using oral fennel for cancer prevention, there is insufficient reliable information about the clinical effects of fennel for this purpose.
• Cholera. Although there has been interest in using oral fennel for cholera, there is insufficient reliable information about the clinical effects of fennel for this purpose.
• Colic. Small clinical studies suggest that oral fennel may reduce crying time in infants with colic. However, most research to date has evaluated fennel in combination with other ingredients. Details: A meta-analysis of three small clinical studies shows that giving fennel to infants with colic can reduce crying time by about 72 minutes daily when compared with placebo (97497). However, the studies included in this meta-analysis were at medium to high risk of bias, and the placebo response rate was high in all of the included studies. Additionally, two of the three studies evaluated combination products (16735,19715,49428). In the one study that used fennel alone, administering 5-20 mL of fennel seed oil 0.1% emulsion daily for one week led to colic relief in 65% of infants, compared with 24% of infants receiving placebo (49428). The other studies evaluated fennel in combination with lemon balm and German chamomile (ColiMil) or in combination with chamomile, vervain, licorice, and lemon balm (Calma-Bebi, Bonomelli). These combination products produced a response in 57% to 85% of infants, compared with 26% to 49% of infants receiving placebo (16735,19715).
• Constipation. Oral fennel has only been evaluated in combination with other ingredients; its effect when used alone is unclear. Details: One small crossover trial in patients with constipation shows that drinking an herbal tea containing 3 grams of a combination of fennel, anise, elderberry, and senna daily for 5 days can decrease colonic transit time, increase the number of daily evacuations, and improve the perception of bowel function when compared with placebo (49494). Another small clinical study in elderly patients with constipation shows that drinking a specific tea (Smooth Move, Traditional Medicinals) containing fennel, senna, licorice, orange peel, cassia cinnamon, coriander, and ginger for 28 days can increase the number of bowel movements when compared to baseline (46196). The validity of this finding is limited by the lack of a comparator group. Additionally, a small clinical study in patients aged 60-65 years with functional constipation shows that taking a traditional Iranian combination product containing 5 grams each of fennel seed and rose flower, dissolved in water twice daily before meals for 4 weeks, improves constipation severity and stool consistency when compared with polyethylene glycol 10 grams. Improvements in constipation severity persisted in both groups 4 weeks after treatment completion (108973). However, polyethylene glycol is usually taken at a higher dose of 17 grams daily, limiting the validity of these findings.
• Cough. Although there has been interest in using oral fennel for cough, there is insufficient reliable information about the clinical effects of fennel for this purpose.
• Dementia. Although there has been interest in using oral fennel for dementia, there is insufficient reliable information about the clinical effects of fennel for this purpose.
• Diabetes. Although there has been interest in using oral fennel for diabetes, there is insufficient reliable information about the clinical effects of fennel for this purpose.
• Dyspepsia. Although there has been interest in using oral fennel for dyspepsia, there is insufficient reliable information about the clinical effects of fennel for this purpose.
• Flatulence. Although there has been interest in using oral fennel for flatulence, there is insufficient reliable information about the clinical effects of fennel for this purpose.
• Hirsutism. It is unclear if topical fennel is beneficial in patients with hirsutism. Details: A small clinical study in females with male pattern body hair due to unknown causes shows that applying a fennel 2% cream twice daily for 12 weeks can reduce hair diameter by approximately 19% when compared with placebo (49429).
• Insomnia. Although there has been interest in using oral fennel for insomnia, there is insufficient reliable information about the clinical effects of fennel for this purpose.
• Irritable bowel syndrome (IBS). Oral fennel has only been evaluated in combination with other ingredients; its effect when used alone is unclear. Details: A small clinical trial in adults with either diarrhea- or constipation-predominant IBS shows that taking two capsules containing fennel essential oil 25 mg and curcumin 42 mg per capsule (CU-FEO, Alfa Wassermann S.p.A.) twice daily for 30 days improves overall ratings of abdominal pain, abdominal distention, and quality of life by 24% when compared with placebo (97422).
• Lactation. Although there has been interest in using oral fennel to stimulate breastmilk production, there is insufficient reliable information about the clinical effects of fennel for this purpose.
• Menopausal symptoms. Small clinical studies suggest that oral fennel oil or fennel seed powder may modestly improve menopausal symptoms. Details: One small clinical trial in adults with medium severity menopausal symptoms shows that taking fennel essential oil 60 mg daily for 8 weeks improves scores on the Menopause Rating Scale when compared with a sunflower oil placebo (97498). Another small clinical study in postmenopausal adults shows that taking fennel seed powder 2 grams daily for 8 weeks improves scores on the Kupperman Menopausal Index when compared with placebo (104198). Fennel has also been evaluated in combination with other ingredients. One small clinical study shows that taking a combination of fennel 120 mg, chamomile 1000 mg, and saffron 60 mg daily for 12 weeks reduces physical, psychological, and urogenital symptom scores on the Menopause Rating Scale when compared with placebo or lower doses of the combination (103628). Additionally, a moderate-sized clinical study in postmenopausal women conducted in Iran shows that taking combined fennel and valerian extract 500 mg twice daily for 8 weeks modestly improves self-reported scores for frequency and severity of hot flashes but does not improve sleep quality or duration of hot flashes when compared with placebo (112369). However, it is unclear if these benefits are due to fennel, other ingredients, or the combination.
• Nausea and vomiting. Although there has been interest in using oral fennel for nausea and vomiting, there is insufficient reliable information about the clinical effects of fennel for this purpose.
• Nocturnal enuresis. Although there has been interest in using oral fennel for nocturnal enuresis, there is insufficient reliable information about the clinical effects of fennel for this purpose.
• Osteoarthritis. It is unclear if oral fennel extract is beneficial in patients with knee osteoarthritis. Details: A small clinical trial in females with osteoarthritis of the knee shows that taking powdered fennel extract 800 mg daily for 2 weeks reduces pain and disability scores, but not stiffness, when compared with placebo (104199).
• Polycystic ovary syndrome (PCOS). It is unclear if oral fennel is beneficial in patients with PCOS. Details: A small clinical study in patients with PCOS shows that taking two fennel capsules, containing anethole 21-27 mg per capsule, daily along with a hypocaloric standard diet or a hypocaloric high-protein diet for 3 months does not reduce body weight or improve androgenic parameters such as testosterone levels, sex hormone-binding globulin levels, or free androgen index, when compared with these diets plus placebo (104197). Fennel has also been evaluated in combination with other ingredients. A clinical study in patients with oligomenorrhea due to PCOS shows that taking a traditional combination product (Aslagh) containing equivalent amounts of essential oils of fennel, wild carrot seeds, and Vitex agnus-castus fruit for 3 months, either alone or in combination with metformin, improves rates of menstrual bleeding and menstrual cyclicity similarly to metformin alone. All three groups experienced a significant improvement from baseline. Aslagh was taken as two, 500-mg capsules twice daily, except during menses; metformin was titrated over one week to a dose of 500 mg three times daily (108974). Additionally, a moderate-sized clinical study in patients with PCOS shows that taking fennel 60 mg and Elwendia persica 25 mg twice daily for 4 months modestly improves number of ovarian follicles and body mass index when compared with placebo; however, when compared to baseline, the combination also improves hirsutism scores and menstrual cycle duration and interval (112370). It is unclear if these effects are due to fennel, other ingredients, or the combination.
• Rheumatoid arthritis (RA). Although there has been interest in using oral fennel for RA, there is insufficient reliable information about the clinical effects of fennel for this purpose.
• Sexual desire. It is unclear if oral fennel is beneficial for improving sexual desire. Details: A small clinical study in postmenopausal adults shows that taking fennel seed powder 2 grams daily for 8 weeks does not improve scores on the Hurlbert Index of Sexual Desire when compared with placebo (104198).
• Sunburn. It is unclear if topical fennel emulsion is beneficial for preventing sunburn. Details: A small clinical study shows that applying a fennel 5% emulsion topically prior to ultraviolet (UV) exposure can reduce sunburn by 65% when compared with a control (49518).
• Upper respiratory tract infection (URTI). Although there has been interest in using oral fennel for upper respiratory tract infections, there is insufficient reliable information about the clinical effects of fennel for this purpose.
• Vaginal atrophy. It is unclear if intravaginal application of fennel cream is beneficial in patients with vaginal atrophy. Details: A small clinical study in postmenopausal adults shows that applying 5 grams of a fennel 5% cream to the vagina once daily for 8 weeks seems to reverse vaginal thinning, improve vaginal pH, and reduce symptoms of vaginal atrophy such as itching, dryness, and pain with intercourse when compared with placebo (92509). Patients in the fennel group also rated their sexual function to be improved when compared with those receiving placebo (97496). More evidence is needed to rate fennel for these uses.

LIKELY SAFE ...when used orally in amounts commonly found in foods. Fennel has Generally Recognized as Safe (GRAS) status in the US (4912).

POSSIBLY SAFE ...when fennel essential oil or extract is used orally and appropriately, short-term. Twenty-five drops (about 1.25 mL) of fennel fruit extract standardized to fennel 2% essential oil has been safely used four times daily for 5 days (49422). Also, two 100 mg capsules each containing fennel 30% essential oil standardized to 71-90 mg of anethole has been safely used daily for 8 weeks (97498). Powdered fennel extract has been used with apparent safety at a dose of 800 mg daily for 2 weeks (104199). ...when creams containing fennel 2% to 5% are applied topically (49429,92509).

CHILDREN: POSSIBLY SAFE
when combination products containing fennel are used to treat colic in infants for up to one week. Studied products include up to 20 mL of a fennel seed oil emulsion; a specific product (ColiMil) containing fennel 164 mg, lemon balm 97 mg, and German chamomile 178 mg; and up to 450 mL of a specific tea (Calma-Bebi, Bonomelli) containing fennel, chamomile, vervain, licorice, and lemon balm (16735,19715,49428).

PREGNANCY: POSSIBLY UNSAFE
when used orally. Observational research has found that regular use of fennel during pregnancy is associated with shortened gestation (100513).

LACTATION: POSSIBLY UNSAFE
when used orally. Case reports have linked consumption of an herbal tea containing extracts of fennel, licorice, anise, and goat's rue to neurotoxicity in two breast-feeding infants. The adverse effect was attributed to anethole, a constituent of fennel and anise (16744). However, levels of anethole were not measured in breastmilk, and the herbal tea was not tested for contaminants. Furthermore, other adverse effects related to use of fennel during lactation have not been reported. However, until more is known, avoid using.
