While no herbs contain true estrogen or progesterone, many contain compounds that mimic these key hormones. Because of this, botanical supplements are commonly used as naturopathic treatments for conditions affecting the female endocrine system. Hormone-mimicking herbs may work effectively to treat complications associated with menopause, sexual problems, infertility and hormone-affecting conditions like polycystic ovary syndrome (PCOS). Anyone interested in taking a hormone-affecting supplement should consult a qualified practitioner for recommendations regarding dosing, safety and potential side effects. Hormone-affecting supplements should be used with caution in women who are pregnant, nursing, taking medication or coping with a hormone-sensitive cancer.
Black Cohosh
An extremely popular supplement for menopausal women, black cohosh contains an estrogen-like compound known as fragrine. The National Institutes of Health's Office of Dietary Supplements notes that black cohosh has historically been used as a treatment for sexual dysfunction, hot flashes and night sweats associated with menopause. Black cohosh stimulates contractions of the uterus; it is an effective abortificant and can be used to induce labor.
Soy
Soy is an excellent source of estrogen-like compounds known as isoflavones. According to Medline Plus, a service of the National Institutes of Health, scientific studies suggest that these compounds can reduce the incidence of hot flashes and night sweats in menopausal women. Soy may also prevent menstruation-related migraines and cyclical breast pain.
Red Clover
Another source of isoflavones, red clover flowers may also help to alleviate breast pain, hot flashes and infertility. The National Center for Complementary and Alternative Medicine suggests that red clover's hormone-affecting properties may contribute to its ability to support prostate health.
Fennel
Fennel, a relative of the dill plant, has been used for centuries to promote the production of breast milk, facilitate childbirth, induce menstruation and treat sexual problems in women. A study published in the Journal of Ethnopharmacology verified that fennel contains compounds similar to estrogen. Note that, while fennel seed tea is generally regarded as safe, fennel oil is extremely toxic.
Fenugreek
Traditionally used in Ayurveda, an Indian system of medicine, fenugreek may contain compounds similar to the female hormone progesterone. The National Center for Complementary and Alternative Medicine states that fenugreek is widely used to increase breast milk production in nursing mothers. Fenugreek may also reduce symptoms of menopause and induce childbirth.
