Bloodroot: A Medicinal Plant

Does anybody know where I can buy the bloodroot powder only for removing skin moles? I also have some verrucas on my feet and wanted to try just the powder, not the salve, as the salve spreads and takes longer. I bought many years ago a powder and it was white and I mixed it with a little water. I emery boarded the mole and applied the paste only to the mole and it went black and fell off, only one treatment was needed and I liked that.

After I was left with a pink mark and eventually a whitish scar but looks better than the mole. If anybody can find just the pure powder please let me know. I think they took it off the net.
