I find it interesting that blood root is used. Blood root was one of the original ingredients in Essiac tea. It was taken out because of its extreme toxicity. Anyone care to venture a guess as to what was in blood root that was considered toxic? Try OXALIC ACID. I'm not at all surprised that it works on melanoma. Please read my previous posts to help understand why this works. What I learned about oxalic acid's ability to kill abnormal cells and not harm normal cells is all there and I might add for a lot less money.
