This 10 oz supply of herbs works with your Hypothalamus to balance out estrogen and manage menopause. Phytoestrogen also known as ISOFLAVONES is contained in some herbs, which mimic the actions of estrogen to communicate with your hypothalamus and "answer the calls." Research shows the right herbs are natural plant estrogen-lookalikes; your body will think that your estrogen level is correct and not bother you with painful and nuisance symptoms. Some of those herbs are Black cohosh, red clover, chaste-tree berry, dong quai, as well as many other powerful herbs.
