The whole article, with every detail and caution.
The fact: black salve is not an approved skin cancer treatment. FDA has warned companies that sold salves with cancer claims, and says these products have not been reviewed for safety or effectiveness. The claim is that a salve can "draw out" skin cancer at home.
What FDA has said about cancer salves
FDA keeps a list of products illegally sold with cancer claims. Salves are on it. The list names a company that sold a product called "Black Salve," one that sold a "Skin Cancer Treatment" salve, and another that sold a salve with cancer claims.
FDA says products like these "are marketed and sold without FDA approval, most commonly on websites or social media platforms." They "have not been reviewed by FDA for safety and efficacy, and can be dangerous to both people and pets."
Why the claim does not hold up
In one warning letter, FDA quoted a seller's claims, such as that the salve "is used to treat skin cancer" and that "the herbs pull out the virus and cancer." FDA said the products were not "generally recognized as safe and effective" for those uses. That makes them unapproved new drugs.
FDA also made a key point about treating yourself. It said the salves are "offered for conditions that are not amenable to self-diagnosis and treatment by individuals who are not medical practitioners." In plain words: you cannot tell on your own what a skin spot is, or whether a salve worked.
The quiet cost: delay
FDA warns that unproven cancer products "may appear harmless, but may cause harm by delaying or interfering with proven, beneficial treatments." Skin cancers have proven treatments. Please do not delay them. Talk with your care team about any product you are thinking of using, or have already used.
When to get help
- If a skin spot is new, changing, or lasts, get it checked by a doctor or dermatologist.
- Contact your care team if you have put a salve on your skin, even if it looks healed. Tell them what you used.
- Call 911 for a medical emergency. For a possible poisoning, call Poison Control at 1-800-222-1222.

Review details and limits
Cancer Explained does not originate medical claims. Every page restates guidance already published by the National Cancer Institute, the CDC, the USPSTF and the FDA, in plain language, with the source cited so you can check the original yourself. AI does the translating and organizing; automated checks test claims, citations, clarity and safety before anything publishes, and this is translation and navigation, not clinical judgment. Nothing here is personal medical advice, and no page can account for your particular situation.
Editorial status — Source checked. This page was written with AI assistance and then compared with the sources listed on it, looking for statements those sources do not back up. That check is not a sentence-by-sentence record and can miss errors. It is not a medical review, and it does not confirm the page is complete or right for your situation.
High-risk topic — talk to your care team. This topic can involve urgent, individual medical decisions. This page is general education only: it cannot tell you whether your situation is an emergency or what you personally should do. Follow your oncology team's instructions and contact them for individual guidance.
Human medical review: not completed. Pages here are not signed off by a clinician before they publish. That is not an oversight we are quietly working around: we restate published guidance and cite it, so the authority belongs to the source rather than to us, and every page names where its claims come from — you can verify us instead of trusting us. Where a volunteer clinician has reviewed a page, their name and credentials appear on it; where no name appears, no clinician has checked it. We are glad to have reviewers and are recruiting them, and we do not hold pages back waiting for one. Use this site to understand your situation and to ask better questions of the people treating you.
