What do you think about herbal estrogens (phytoestrogens, dong qwai, black cohosh, etc.)?
I am unaware of any reliable published data about the beneficial effects or side effects of these substances. Reputedly these are weak estrogens. As such, they may result in limited feminization, and may be ineffective at suppressing testosterone. I think most people would do better with pharmacologic estrogens. I cannot address any other questions regarding non-pharmacologic estrogens.
