Pattison used goldenseal rather than bloodroot. I love bloodroot and have a little growing in my garden, but I have heard too many bloodroot stories to recommend bloodroot to the uninitiated. It is a highly unpredictable herb, very potent, interesting, dramatic, and precious, but not controllable.
Goldenseal salves are different.
They seem to permit some cells to return to normal. They also work more slowly and are therefore not appropriate when time is an important factor. There are many salve products and they are not all equal. I have deliberately not included instructions for salve use on this site because people really do need to read the book before commencing use of such products. This treatment is far too complex to be undertaken lightly, and cancer is too serious for errors.
