Flash: Plant Estrogens Don't Help: "Flash: Plant Estrogens Don't Help Posted 10/07/2003 Summary Phytoestrogens, commonly found in edible plants such as soybeans and red clover, bind weakly to the estrogen receptor and are marketed widely as a nonhormonal treatment alternative for hot flashes. But, do they work? In this double-blind trial, 62 postmenopausal symptomatic women were randomized to receive phytoestrogens (isoflavonoids, 114 mg/day) or placebo for 3 months; after a 2-month washout period, the women crossed over to the other arm for 3 months. All women previously had been treated for breast cancer and complained of incapacitating hot flashes, night sweats, and sleeplessness."

hmm... didn't have a clue about this - KK
