Vitex / Chaste Tree

Scientific Summary

Vitex agnus‑castus, known as chaste tree, is a small deciduous shrub whose ripe fruit and leaves are harvested for herbal preparations. It is primarily used to support reproductive and hormonal balance, helping with premenstrual syndrome, irregular menstrual cycles, breast tenderness, and to promote lactation. The herb is generally well tolerated but can cause mild stomach upset or dizziness, and should be avoided during pregnancy or when combined with hormonal medications unless a provider advises otherwise.
