Chaste tree (vitex agnus-castus), or chasteberry, has been used for centuries in herbal medicine for a variety of hormonal-related and gynecological conditions. Traditionally it has been used to help reduce PMS symptoms, increase fertility, help with cyclic mastalgia, and help balance hormones during menopause. Studies have also shown it to have antimicrobial properties, help bones, heal, and help urine output in men suffering from benign prostate hypertrophy (BPH). *
