Hi, Hot flashes were one of the most aggravating aspects of my Stage 4 prostate cancer experience. My wife shared something that helped her when she was going through menopause. Black Cohosh ! I guess that women have been sharing this between themselves for many years. It is also inexpensive and easy to find. Any vitamin store, CVS or Whole Foods carries it. I take one capsule in the morning, and one capsule just before going to bed. Occasionally I forget. When I do the sweats return like gangbusters. So, I know that it is making a difference. Since Black Cohosh is a vitamin supplement, it is not verified by the AMA. But, you have nothing to lose by trying it. I suspect that relief is just a capsule away.
