Practicing after he lost his license, chiropractor Nicholas LeRoy used escharotics to treat a woman's cervical dysplasia. As result, she lost her uterus. Ex-naturopath Britt Hermes was taught to use escharotic treatments at Bastyr; she has since realized that they are "unproven, dangerous, and very stupid."
Bloodroot (Sanguinaria canadensis) and black salve (which contains bloodroot) are promoted and sold as a cure for many things, including cervical dysplasia. While it does kill cancer cells, it does so just like a flamethrower - indiscriminately, killing lots of normal cells along the way.
