"Bloodroot paste is made using either bloodroot sap or dried, powdered bloodroot. Zinc oxide, a substance commonly found insunscreen and calamine lotion, is often added to help soothe and protect the skin. Another common additive is chaparral extract, which is taken from the shrub of the same name. In alternative medicine, chaparral is believed to have detoxifying properties. These ingredients are often cooked together with water and white flour to produce bloodroot paste that can then be applied topically."

"According to herbalist Pam Montgomery in the book "Planting the Future: Saving Our Medicinal Herbs" by Rosemary Gladstar and Pamela Hirsch, bloodroot was mixed with zinc oxide, flour and water to create the first black salve for treating skin cancers by an English doctor in the 19th century. A "Dr. Fells" used this formula to treat skin cancers in London and claimed that it was more effective than surgery. Bloodroot was recognized by the U.S. Pharmacopeia (USP), which sets standards for all prescription and over-the-counter drugs in the United States, until the early 1900s and was included in the USP-National Formulary until the 1960s, but is now classified as poisonous because of possible side effects when taken internally."
