TGA warns against black or red salves to treat skin disorders
The TGA said it had been notified of three cases where consumers had caused serious harm to their skin by using the salves.
“The TGA is not aware of any credible scientific evidence which shows that any black or red salve preparation is effective in treating cancer,” the regulator said in a website post last week.
“Both black and red salves are corrosive and essentially burn off layers of the skin and surrounding normal tissue… and leave significant scarring.”
Health authorities were investigating the supply and advertising of these treatment products, also known as Cansema or Bloodroot (Sanguinaria canadensis with the active caustic ingredient sanguinarine), the TGA said.
