Vitex is one of the most popular botanicals in Europe for treating menstrual disorders and has been recognized as gentle and effective for 2,500 years.  Numerous clinical studies document its benefit.

The dried ripe pepper-like fruit of the chaste tree (Vitex agnus-castus) is used quite frequently as an ingredient in supplements.
Vitex berries contain essential oils, flavonoids and glycosides.  Two of the iridoid glycosides, agnuside and aucubin, have been used to measure potency, and have even been used for standardization markers.  The hypothalamus and pituitary glands are responsible for triggering the female hormonal cycle.  By increasing levels of luteinizing hormone and mildly inhibiting the release of follicle stimulating hormone, Vitex is able to shift the ratio of estrogen to progesterone slightly in favor of progesterone.
Clinical studies using vitex extract show a reduction in headaches, breast tenderness, bloating, fatigue, cravings for sweets, and also feelings of anxiety, irritability, depression and mood swings, after only one month.
The safety of vitex is exceptional – in one study, vitex was given up to 9 years in some cases, with very few side-effects.
