My mother read in one of her urban legend "housewife tale" books that potato skins (white side on the skin, under a bandage) would remove all manner of skin issues. This definitely worked for warts, but I'm not sure if by the same mechanism as duct tape. N=1, but this also worked for some sort of embolism that I had on my wrist.
