Alfalfa also has components that
promote estrogenic activity in women whose own sex hormone production has declined; thus, it is thought to have helped many women with the discomforts of menopause and pre-menstrual syndrome.
Edit 2017: Recently, after learning about new research and working with even more women, I'm finding that plant - based phytoestrogens may
promote ER beta
activity, which can lower
estrogenic potency in the body as a whole, thereby decreasing the risk for certain cancers (this is not true of synthetic estrogen, like that in hormonal birth control or estrogen replacement therapy).
