In devising an anti-cancer protocol I include supplements in high doses and as Dr. Snuffy Myers says...:supplements are dirty drugs and when taken in high doses can have drug like effects. But, I stay away from herbals...if I want a certain compound found in a herbal..I will buy a supplement containing that compound and not the herbal because the herbal contains many other compounds that can be harmful in high doses. I have been having a discussion with Nalakrats, who is real smart about nutrition, but also takes herbals as part of his protocol. Nal could be right, but read the article below which outlines reasons to be careful about herbals and supplements in general.
