Chaste berry (Vitex agnus castus) is native to Western Asia and Southwestern Europe. Chaste berry is used as a common treatment for gynecological disorders due to its central dopaminergic activity. It has been used widely in Europe for gynecologic conditions such as premenstrual syndrome (PMS), cyclical breast discomfort, menstrual cycle irregularities, and dysfunctional uterine bleeding. Major active constituents of Chaste berry are iridoid glycosides such as agnuside, aucubin and flavonoids such as casticin. Chaste berry acts as a hormonal modulator by increasing progesterone levels with the corresponding reduction in estrogen levels via the corpus luteum hormone effect. It shows central action at the pituitary gland that inhibits the release of follicle-stimulating hormone (FSH), promotes the release of luteinizing hormone (LH), and decreases prolactin secretion by the pituitary gland via dopamine antagonistic effect. It is also used for fibrocystic breast, insufficient lactation, corpus luteum insufficiency, prevention of miscarriage in the first trimester of pregnancy in cases of progesterone insufficiency and acne vulgaris.
