Cansema black salve is a corrosive salve used to treat skin disorders. It is considered an escharotic, meaning that it burns away skin, causing tissues to die, leaving a black, dry scar, much like a burn that eventually sloughs off. The contents of cansema black salve usually include bloodroot and zinc chloride, both of which are considered active ingredients.
Production of black cancer salves is not regulated by any governmental or health agency, and the exact ingredients in cansema and other similar salves may be different from what is listed on the package. While escharotics were once the best medical treatment available for skin lesions and skin cancer, most medical professionals currently consider the treatment outdated and dangerous.
Most cansema purchases occur online because the product is difficult to find in stores. While the original, full strength product is intended for humans, there is a milder version for use on pets. This product is not intended for consumption and can be quite toxic, so caution must be used to keep it away from children and animals.
The salve is applied with the fingers directly to the cancerous area to make a thin covering, and then a bandage is applied over the caked salve. A tingling sensation begins shortly afterward, though this can take many hours to start. After 24 hours, the eschar must be cleaned with rubbing alcohol, and this cleaning must be steadily maintained to prevent a buildup of pus. Once the eschar falls out, which typically occurs after ten days, the treatment is over and the cancer has been, according to cansema producers, completely removed.
Proponents of cansema black salve make many claims as to its effectiveness, many of which are highly questionable. They claim that cansema only burns away aberrant cells, leaving healthy tissue alone. Also, they state that applying cansema to healthy cells will only cause redness, while cancerous cells will be eaten away. This, they say, means that cansema black salve can be used as a cancer test of sorts, as the result of its application will determine whether the cells were cancerous at all. Some go so far as to say that cansema can draw out cancers and therefore can be used for internal cancers.
While it is possible that an escharotic such as cansema black salve could work to remove surface lesions including cancerous cells if applied correctly, the product also damages healthy skin and can result in serious tissue damage. In addition to the possibility of burning holes through skin and other tissues, which will necessitate major plastic surgery, there is also a serious possibility that even when the product appears to have worked and the surface lesion has disappeared, cancer can still exist under the skin.
Black salve cannot draw out cancer from under the skin, nor get rid of cancer that has spread to other parts of the body from the original site. The product is not only ineffective but also frequently dangerous, so cansema black salve has been discredited by almost every reputable American medical institution, and has been listed by the Food and Drug Administration as a fake cancer cure.
