Chaste Tree contains high-quality Chaste Tree berries to support healthy female hormone balance. Traditionally used in herbal preparations to: • Support healthy prolactin and progesterone levels in the body • Encourage healthy menstrual cycling • Ease discomfort associated with premenstrual syndrome • Support normal reproductive function in women* Chaste Tree contains flavonoids (especially methoxylated flavones), iridoid glycosides (such as aucubin), diterpenes, sesquiterpenes, an essential oil and other compounds. Chaste Tree (Vitex agnus-castus) contains three important classes of phytochemicals: iridoid glycosides (such as agnuside and aucubin), flavonoids (such as casticin) and diterpenoids (such as vitexilactone, rotundifuran and vitetrifolin D). It is believed that the diterpenoids are the more important of these constituents and therefore MediHerb has developed analytical methods for the determination of these constituents and manufactures extracts containing high levels of these diterpenoids, but not at the expense of other vital components.
