Properties and effects of fennel seeds for women’s and men’s health

Fennel is a perennial Mediterranean plant with a pleasant aroma and yellow flowers that is now found all over the world. Dried fennel seeds are often used in cooking as a spice similar to anise. In addition, dried seeds and fennel oil are used to make medicine. Fennel is used orally for infant crying (colic), indigestion, menstrual cramps, and menopausal symptoms, but there is no good scientific evidence to support this.

In foods and beverages, fennel oil and seeds are also used as flavorings. In other production processes, fennel oil is used as a flavoring agent in some laxatives and as an aromatic substance in soaps and cosmetics. According to WebMD, fennel relaxes the colon, and also contains a substance that acts like estrogen in the body.

Cases in which the effect of fennel has not been paid much attention:

Excessive crying in infants (colic): Preliminary research shows that giving fennel to infants with colic reduces their crying slightly.

Menstrual cramps: Consumption of fennel extract 4 times a day from the beginning of a period can reduce the pain of girls and young women during menstruation, but not all research shows these results.

Male pattern hair growth in women (hirsutism): Using fennel cream for 12 weeks reduces hirsutism.

Menopausal symptoms: Preliminary research shows that consuming fennel oil improves menopausal symptoms.

Sunburn: Using fennel on the skin before sunbathing reduces sunburn.

Thinning and drying of vaginal tissue (vaginal atrophy): Using fennel cream once a day for 8 weeks reduces the symptoms of thinning vagina such as itching, dryness and pain during intercourse.

Further evidence is needed to evaluate the effectiveness of fennel for these uses.

When taken orally: Fennel is likely to be safe in the amounts normally found in food. It is probably safe when used in appropriate doses for a short time. There is not enough reliable information to know whether fennel is safe for long-term use as a medicine. Although rare, its side effects can be upset stomach. Seizures have also occurred in some people when consuming essential fennel oil orally.

When rubbed on the skin: Fennel is probably a safe option, but in some people fennel causes the skin to be too sensitive to the sun and cause sunburn, so it is best to use sunscreen.

Special warnings and precautions

Pregnancy: There is not enough reliable information to know if using fennel during pregnancy is safe, so for the health of yourself and your baby, avoid using it during this period.

Breastfeeding: Fennel is probably not a safe option during breastfeeding. Two infants have been reported to have damaged their nervous system after their mothers drank herbal tea containing fennel.

children: Fennel is probably safe to use in appropriate doses in children with colic for up to a week.

Allergy to celery or carrots: Fennel causes an allergic reaction in people who are sensitive to these plants.

Bleeding disorders: Fennel slows down blood clotting. Consumption of fennel also increases the risk of bleeding or bruising in people with bleeding disorders.

Hormone-sensitive conditions such as breast cancer, uterine cancer, ovarian cancer, endometriosis or uterine fibroids: Fennel acts like estrogen, so if you have a disease that is made worse by estrogen, avoid fennel.

Drug Interactions:

Birth control pills (contraceptives) interfere with fennel.

Some birth control pills contain estrogen, fennel has the same effects as estrogen, but is not as strong as the estrogen found in birth control pills. Consumption of fennel in combination with birth control pills reduces the effectiveness of birth control pills. If you are taking birth control pills with fennel, use another method of birth control such as condoms.

Ciprofloxacin interferes with fennel

Ciprofloxacin is an antibiotic that fennel may absorb the amount of ciprofloxacin in the body. Consumption of fennel with ciprofloxacin reduces its effectiveness, so to prevent this interference, fennel should be consumed at least one hour after ciprofloxacin.

Estrogens interfere with fennel

Large amounts of fennel have the same effects as estrogen, but fennel is not as strong as estrogen pills. Consumption of fennel with estrogen pills reduces the effectiveness of estrogen pills.

Tamoxifen interferes with fennel

Some types of cancer are affected by the body’s hormones. Estrogen-sensitive cancers are cancers that are affected by estrogen levels in the body. Tamoxifen is used to help treat and prevent this type of cancer. Fennel seems to affect the amount of estrogen in the body. Consumption of fennel with tamoxifen reduces the effect of tamoxifen.

The proper dose of fennel consumption depends on various factors such as age, health status and several other factors. At present, there is not enough scientific information to determine the appropriate range of fennel dose. Remember that natural products are not always safe and the amount consumed is important. Be sure to read the instructions on the product label and consult your doctor before use.
