What is Vitex Agnus-castus?

Vitex agnus-castus is the fruit of the chaste tree. The fruit and seed are used to make medicine.

Is Vitex Agnus-castus effective?

There is some scientific evidence that chasteberry can reduce 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.
