How does black salve cure skin cancer ?

I'm not sure whether it helps because it is an experimental therapy. It is better to see a naturopath to know if black salve really helps.

Black salve is a paste, poultice, or ointment made of various herbs. It's applied directly to areas on the body with the hope of burning away or "drawing out" cancer.
Black salve is commonly made with zinc chloride or the flowering North American plant bloodroot (Sanguinaria canadensis). Bloodroot contains a powerfully corrosive alkaloid called sanguinarine.
Black salves are classified as escharotics because they destroy skin tissue and leave behind a thick scar called an eschar.
Black salve was commonly used during the 18th and 19th centuries to chemically burn off tumors that were isolated to the top layers of skin. It has been promoted and used by naturopaths as an alternative cancer treatment with dubious results.
Scientific studiesTrusted Source doesn't support the claims that black salve is an effective treatment for melanoma and other types of skin cancer. On the other hand, some alternative medical practitioners believe black salve:
reduces excess fluid
enhances oxygen flow to the brain
decreases all malignancies in the body
strengthens enzyme structure
Every single one of these claims is unsubstantiated.
