I doubt a dermatologist would suggest Black Salve. They have other methods like liquid nitrogen, and curettage if it has become a small cancer. Quack Watch says Black Salve very very bad! (of course they do.) I suppose if you use it incorrectly it is, but if you follow Dr. Wilson’s instructions it works well. I bought the salve a couple years ago, it took me this long to get up the nerve to try it. But it WILL leave a small hole in the skin if the cancer has been there a while. The hole will fill in gradually, and using emu oil helps it heal. It can be a little scary using it on your face, for obvious reasons. But I have been, with good results.
