Herbal Chaste Tree Berry Anti Estrogenic Activity

Chaste tree berry(Vitex agnus-castus), is found to process anti-estrogenic property in binding the estrogen receptors for a balance between the activities of estrogen receptor ERα or ERβ.

The herb is a species of Vitex agnus-castus, genus Vitex, belonging to the family Lamiaceae, native to the Mediterranean region, used in herbal medicine for thousands of years as anaphrodisiac herb and considered as Queen herb in treating menstrual problems and discomforts.

Anti estrogenic effects are an act of binding the estrogen receptor(ERα ) and/ERβ in inhibiting the excessive levels of estrogen circulating in the body.

According to the University of Alabama in Huntsville, in the study of the potential effect of estrogen mimics or anti-estrogens in phytochemicals of popular dietary herbal supplements, researchers found that almost all herbal supplements containing phytochemical components showed a capability in binding to the human estrogen receptor and exhibit selective estrogen receptor modulation, including chaste tree berry.

Casticin, a flavonoid isolated from Vitex rotundifolia, significantly expressed anti estrogenic effect in reduced the prolactin release stimulated by E2 in induced inhibition of ERα mRNA expression in a concentration-dependent manner, through its anti estrogenic effect.
In a hyperprolactinemia (MIHP) induced by administration of metoclopramide dihydrochloride (50 mg/kg, tid, ip, for 10 d) in SD rats, rat treated with casticin (10, 20, and 40 mg/kg, ip, for 7 d) reduced serum prolactin levels by 33.9%, 54.3%, and 64.7% and at(1 and 10 micromol/L) inhibited E2-induced pituitary cell proliferation by 27.7% and 42.1%, respectively through reduced levels of 17β-Estradiol (E2) significantly.


More importantly, oral administration of casticin, a flavonoid isolated from Vitex rotundifolia displayed an anti-estrogenic activity in decrease excessive levels of 17β-Estradiol (E2) significantly


Taking together, Chaste tree berry processes strong estrogenic and anti-estrogenic effects in binding estrogen receptor sites to preserve the balancing of hormone expression of estrogen through ER alpha and ERBeta inhibition and exhibition.
