I think hot flashes remain quite a mystery still for most allopathic and natural doctors. I have never found any herb, diet or natural hormone (except synthetic estrogen) that has ever stopped them. I do think controlling emotions can help quite a bit but sometimes I feel that most flashes are unexplainable. I have one every morning as soon as I wake up and some as soon as I lay down at night. Of course I have them at other times too. (refreshed 48124)
