I had heavy periods all my life and never knew what to do for them. And when I was in my forties, I had such heavy periods, I gotten weak and couldn't hardly walk. Then I had to have a hysterectomy, not what I wanted, but that's the only solution the doctors could come up with and I hated it, hated it. I also went to more than one doctor and they were repeating the same thing. I ask them about other things that I may be able to do and nothing. Why do they just want to butcher women I do not know, instead of trying to find another solution to the problem. But a woman has to get all the info. that she can to keep from getting cut by a knife. Ladies be very careful, get other opinions as well. The natural medicines works beat and we know it. So sorry to hear about your sis.
