I checked out "The Essiac Report" unknown cancer remedy from our library. It gives a tea made from 4 herbs: Sheep Sorrell, Burdock Root, Slippery Elm Bark and Rhubarb Root that are supposed to cure/shrink tumors, and a lot of other things, and no known side effects. Began as a remedy from an Indian and progressed to Flor-Essence that you mix with hot water and drink as a tea. A detoxifier also.
