This is all I was able to find on red clover aka Trifolium pratense from Aust J Med Herbalism 1992;4:(3):28.The main phytoestrogen responsible for the infertility of animals grazing on red clover is formononetin which is metabolized to equol and 4'-O-methylequol to produce estrogenic effects. It is hepatotoxic but the levels of it required to cause illness in humans is not known. Tea is made from stems and leaves and varies depending on the soil content of phosphates (a deficiency causes higher levels), and weather (spring, autumn and cool summers (also associated with increased levels). I had a patient who was growing and brewing her own red clover tea. She presented with perimenopausal bleeding but also had significant upper GI distress. She was being followed by a GI specialist who did not know about her tea drinking habits. We only learned by pursuing a herbal history after she admitted to taking several other more common herbal preps. Hope this helps.

The American Medical Association is no longer designating CME hours for AMA Category II CME credit. However, physicians themselves may self designate learning activities as Category II CME credit hours if they feel it is of sufficient educational merit and meets the formal definitions of continuing medical education. OBGYN.net believes these interaction in this forum meets these criteria. For further information see the AMA web site.
