Fig. 5From: The premenstrual syndrome, premenstrual mastodynia, fibrocystic mastopathy and infertility have often common roots: effects of extracts of chasteberry (Vitex agnus castus) as a solutionDispersed rat pituitary cells secrete large amounts of prolactin which are profoundly inhibited by DA. The VAC extract BNO 1095 inhibits prolactin release which is further evidence for dopaminergic activity of this extract. The DA 2 receptor specificity is proven by the reduction of the inhibitory effects of both, DA and VAC BNO 1095 by haloperidol, a DA 2 receptor blockerBack to article page
