The dried berry of the chastetree shrub (Vitex agnus-castus) has a long history of traditional use for female hormone balance. It acts on the pituitary gland to encourage normal progesterone levels. You will find it as capsules, tinctures, or liquid extracts, typically taken once daily in the morning. Noticeable effects often require several menstrual cycles of consistent use.
People reach for chastetree to ease premenstrual discomfort, promote menstrual regularity, and relieve breast tenderness.
Do not combine chastetree with hormonal medications such as birth control pills or hormone therapy. Avoid it during pregnancy and while breastfeeding.
