Orahesive Powder is a super wound covering for use on ulcers, etc. The powder adheres to mucous membranes, open wounds, etc. The powder forms a film coating over the wound on contact with liquid, unlike creams that tend fall off in a big lump. Orahesive powder creates a thin coat that stays in place for about 24 hours. Please wear gloves when applying this powder, because it sticks just as well to your fingers.
