In the West, chastetree has been employed as a "woman's herb" from the time of classical antiquity. Modern scientific research has corroborated many of its traditional uses.
In recommending the therapeutic use of chastetree for the symptoms of menopause, James Duke explains that, "The biochemistry is complicated, but basically chasteberry regulates hormones involved in the menstrual cycle. It increases luteinizing hormone production and inhibits the release of follicle-stimulating hormone. All of this translates into a beneficial estrogenic effect."
