Vitex (Vitex agnus-castus) – also called Chaste Tree, or Chaste berry – contains several different constituents, including flavonoids, iridoid glycosides, and terpenoids. It has a long history of use in herbal medicine, and is primarily used today to alleviate premenstrual syndrome symptoms. Vitex has outperformed placebo in numerous trials, and is known as nature’s hormonal balancer. While it doesn’t appear to contain any active hormones itself, vitex acts on the hormones via its effect on the pituitary gland (and specifically on the production of luteinizing hormone, or LH). Vitex also keeps prolactin secretion in check (more on that below) and improves both estrogen and progesterone levels.

Vitex has been shown to help balance of estrogen and progesterone during the menstrual cycle and may alleviate PMS symptoms.

Vitex has been shown to improve fertility, particularly for women with luteal phase defect, it should be discontinued once a woman becomes pregnant.

Agnus castus has been shown in some studies to reduce breast tenderness.
