I used black salve on three spots on my head and one on my side now... one of those was on my nose and I have never had any difficulty with healing... there was some minor pain but nothing more than what i would have had if surgery would have been performed to remove the skin cancers... The people at http://www.altcancercream.com have a lot of information and if you interested in black salve its a good read. I have never used their bloodroot paste but they do have one in their product listings.
I can truly say this 50 bucks was the best money i every spent and if the need arises again i will purchase and use the black salve product again.
