I have heard of it, mainly in organic circles and was used as a "drawing salve" where it pulled foreign debris from the skin. (also known as cansema)

While I have heard some positive results on this, I have also heard cries of Blasphemous medical advice. Being in the medical field, I can honestly say that I would rather pass it through a dermatologist just to be safe. I can see now that you have already decided this, should you ever need it.

I believe that to be the best choice.
