Black salve

Cansema (or generically black salve) is a brand name of a popular alternative cancer treatment. The product is commonly classified as an escharotic. —The Free Online Medical Dictionary. It functions by attacking and destroying human skin tissue and creating an eschar, or piece of dead tissue."Escharotic agents." DermNet NZ. New Zealand Dermatological Society. 2010 August 28. The product will consume cancerous and healthy cells without discrimination. As such, it can be destructive and dangerous to patients. Even more alarming, cansema is often used in conjunction with the solvent DMSO,FDA: 187 Fake Cancer "Cures" Consumers Should Avoid which increases its absorption.
Common ingredients of black salves usually include zinc chloride, chaparral (Larrea tridentata), and bloodroot (Sanguinaria canadensis), but also galangal (Alpinia officinarium), ginger (Zingiber officinale), and graviola (Annona muricata).Black Salve (also known as Cansema)
Escharotics were commonly used to treat skin lesions in the early 1900s, but have been replaced with treatments that don't just leave a hole. However, they are now promoted as an "alternative" medicine.
