Interesting story about the skin cancer - my friend from Georgia told me the same thing about his grandmother. Somebody had been diagnosed with melanoma. He was a kid at the time and she had him and his brother gather up large quantities of some kind of "weed" - he doesn't remember what it was called - she showed him what it was and made him gather as much as he could find. She made this into a poultice and after a couple of weeks her patient's skin cancer was gone - just left a scaly patch like in the post above. Of course this is another anecdote and there's no scientific proof - (was it really skin cancer, etc. etc.) Just thought I'd pass it on.
