GnRH and TRH tests were performed in 8 women to evaluate TSH and Prl responses before and after 3 months of therapy. The plants product induced a significant increase in Prl and TSH response to TRH. Basal levels of estradiol, LH, FSH, Prl and TSH were unchanged.
Conclusions: The product seams to have a central slight antidopaminergic action without side effects and is an effective agent in the treatment of menopausal symptoms.
