The active agent in comfrey is allantoin, which fostersthe growth of new cells. although the dried roots and leaves are used for medicinal purposes, the comfrey root contains up to twice as much allantoin as the other parts. While its internal use is questionable, comfrey can be used safely on external injuries such as cuts and other wounds.
