Sound dangerous to me – like you could be stripping important protective linings away. Mankind has gone a million years not worrying about it; now suddenly it’s a major health concern. I can’t turn on the TV or radio and not see or hear an infomercial about it. Or is this just another gimmick to convince people to spend money on homeopathic remedies they really don’t need? I also heard that there could be some dangerous and untested compounds in these preparations that can cause kidney damage. Is this true?
