Chaste Tree: Herbal Remedies

©2007 Publications International, Ltd. Chaste tree is an herbal treatment used mostly for menstrual complaints.

Vitex, also known as Chaste Tree or Monk's Pepper, was said to be used as herbal remedy by monks in the Middle Ages to diminish their sex drive, and its common names stem from its use by monks to maintain celibacy. Although it does seem to occasionally reduce sex drive in women, the effects are less pronounced than the name of this plant suggests.

Uses for Chaste Tree

In modern times, chaste tree is used primarily as a women's herb for menstrual complaints. The flavonoids in chaste tree exert an effect similar to the hormone progesterone, although the plant contains no hormonal compounds. Chaste tree acts on the pituitary gland in the brain, normalizing the release of both follicle stimulating hormone (FSH) and luteinizing hormone (LH).

The overall effect is to regulate the menstrual cycle and slightly increase the production of progesterone in women who otherwise have irregular cycles. Many menstrual complaints are known to result from a relative lack of progesterone. When progesterone levels are low relative to estrogen, the result is often infertility, heavy bleeding, lack of periods, too-frequent periods, irregular periods, and premenstrual syndrome. Because it helps normalize LH levels, chaste tree alleviates these complaints. It can normalize and regulate menstrual cycles, reduce premenstrual fluid retention, and treat some cases of acne that flare up during menstruation.

Chaste tree's berries also can be used for menopausal bleeding irregularities, such as frequent or heavy bleeding; it is often combined with hormonal herbs such as black cohosh or soy. Therapy of six months to one year is usually recommended.

Chaste tree is a slow-acting herb and can take months to produce effects. When treating infertility, chaste tree is continued for one to two years; it is discontinued if pregnancy occurs. Because the constituents in chaste tree -- including flavonoids, iridoid glycosides, and terpenoids -- gradually normalize FSH and LH levels, it helps allow for normal ovulation and pregnancy. Chaste tree also lowers the hormone prolactin, produced during stressful periods, which also may cause tender breasts and uterine cramps associated with PMS.

Chaste Tree Preparations and Dosage

Chaste tree berries are typically tinctured or powdered and used in capsule form. The flavor is unpleasant, so chaste tree is not a popular tea.

Tincture: Take 1/4 to 3/4 teaspoon, one to three times daily, and reduce the dosage when effect is noted. Although effects can be more rapid, it may take three months before you see improvements.
