Comfrey has long been used as a medicinal herb, applied externally it is said to promote the healing of wounds. There is, however, little scientific evidence for this. Because cosmetics are not about proof, but about the belief that users attach to the action of certain ingredients, it has been used in cosmetics for many decades. For that reason it is nowadays made synthetically, extraction from natural source would make it way too expensive.
