Agnus Castus Fruit Extract as a Treatment for Premenstrual Syndrome

During the period before menstruation, many women report experiencing psychological and physical symptoms collectively referred to as premenstrual syndrome (PMS). The fruits, leaves and flowers of Vitex agnus castus (the Chaste Tree) have traditionally been used to relieve these symptoms. While the mode of action is not clear, the effects of the plant seem to mimic those of the corpus luteum, stimulating the production of lutenizing hormone, thereby increasing progesterone production. Schellenberg and colleagues recently studied the effects of agnus castus fruit in women with premenstrual syndrome.
