Dont be afraid to chime in; we all have done mistakes, IMO it is part of the learning process. A tip is to look at the posting history. Now and again some say that Iodine ruined their life, then just know it can happen with any substance; like a herb //www.curezone.org/forums/am.asp?i=2214630
My guess would be that he took the herb at a time where he was developing a health issue, that it would have happened if he took it or not.
