common comfrey, Symphytum officinale

Comfrey retains a reputation as a homeopathic cure for bone and joint problems. In days of yore, casts were made from mashed roots that were formed and dried around broken bones. That was unquestionably an effective treatment. Other uses of poultices or internal dosages are more questionable. We now know that consistent use, even externally, can cause liver toxicity.
