Vitex agnus-castus is sometimes called "the women's herb." It is used for menstrual cycle irregularities, premenstrual syndrome (PMS), a more severe form of PMS called premenstrual dysphoric disorder (PMDD), and symptoms of menopause. It is also used for treating "lumpy" (fibrocystic) breasts, female infertility, preventing miscarriage in women with low levels of a hormone called progesterone, controlling bleeding and helping the body force out the placenta after childbirth, and increasing breast milk.
Some men use vitex agnus-castus for increasing the flow of urine, for treating benign prostatic hyperplasia (BPH), and for reducing sexual desire. Historians say that monks chewed chaste tree parts to make it easier to maintain their celibacy.
Vitex agnus-castus is also used for acne, nervousness, dementia, joint conditions, colds, upset stomach, spleen disorders, headaches, migraine, eye pain, body inflammation, and swelling.
Some people apply vitex agnus-castus to the skin to flush out parasites and to prevent insect bites and stings.
symptoms of premenstrual syndrome (PMS), especially breast pain, bloating, depression, headache, and constipation. It may take up to three months of treatment before there is a noticeable improvement. Chasteberry may not be as effective for women who have the type of PMS that has food cravings, dizziness, sweating, and rapid heartbeat as its main symptoms.
There is also evidence that chasteberry might help improve acne after about six months of use.
Studies are beginning to show that chasteberry may help women who have trouble getting pregnant because they don't have enough of the hormone progesterone. But chasteberry doesn't work quickly. Women may need to be treated for up to 7 months.
There isn't enough information to know if chasteberry is effective for the other conditions people use it for, including: menopausal symptoms, prevention of miscarriage, enlarged prostate, and many others.
