No. Human (animal) hormones are signaling molecules having crucial roles in genomic regulation. Chemical modification of estradiol by an ethynyl radical yielded a synthetic hormone capable of binding to estrogen receptor. This synthetic hormone caused many difficulties in the human practice as primarily inhibits the receptor and provokes compensatory upregulation of estrogen signaling. Synthetic hormones may be blamed for the toxic and carcinogenic effects of contraceptives and menopausal hormone therapies. Hormones originated from plants, such as phytoestrogens and resveratrol, are highly different from human hormones and they are endocrine disruptors. In small doses they may exert estrogen-like activities, however, long term use, or elevated doses result in toxic complications. By contrast, yam root comprising DHEA is a good activator for peripheral estrogen synthesis. It has no hormonal effects, however, provides a source for natural androgen and estrogen synthesis. Yam root supports bone regeneration.
