I have formulas for escharotic cancer salves that has a light salve used with the better-known bloodroot black salve. The light salve both draws and kills infection. I just used it on my little granddaughter who got some kind of bite that itched and then became very painful. The light salve drew it up to a head filled with pus and when she went home to mom a few days ago, it was the size of a pencil eraser, so it was really drawing stuff out. I found out later the little one was terribly allergic to bites of any kind and had been hospitalized with them in the past. But this stuff took the redness and pain in a couple of days. It's made of beeswax, resin, linseed oil and lavender oil. The recipe is on my site: http://www.truthquest2.com/cancersalves.htm
I also used it on our dog where she gets what may be allergic reactions to bites of her own. It cleared those up but also a lump on her belly disappeared, so it may be even more potent than I realized. Coincidently, I saw below that dusan mentioned using beeswax. I had thought that ingredient was just to make the "potion" more salve-like but maybe it has medicinal properties of its own.
