Vitex helps restore a normal estrogen-to-progesterone balance. It can not only ease but, with time, actually cure premenstrual syndrome, which has been linked to abnormally high levels of estrogen, especially if symptoms tend to disappear when menstruation begins. Vitex can also help with irregular menstruation (especially if accompanied by endometriosis). Vitex also helps resolve hormonally-related constipation. Vitex may help cure fibroid cysts that occur in the smooth muscle tissue.
Vitex may also help reduce some of the undesirable symptoms of menopause such as hot flashes associated with the reduction in the production of progesterone. Vitex can stabilize the cycle after withdrawal from progesterone birth control pills.
Several studies indicate that vitex can help control acne in teenagers, young women and men.
For women who are trying to get pregnant, vitex may be helpful to help regulate the ovulatory cycle. It may be taken throughout the end of the third month of pregnancy, which may help prevent miscarriage, according to German research. After the third month it is still safe to take but is not recommended, because it may bring on the flow of milk too early.
