Widely acknowledged as being an herb of great medicinal value, Comfrey Leaf has been known throughout the ages under a wide variety names with Bruisewort, Knitback, Boneset, Slippery Root, Ass Ear, and Blackwort being among them. In China, it has been used for well over 2000 years, and has maintained its reputation well enough to see mention in a US Pharmacopia and numerous other medical journals and herbal compendiums throughout the world. Most commonly, it is used as an ointment or poultice that is applied to sprains, broken bones, and other wounds where it is said to help in mending and healing. In ancient times, it was also said to be quite potent in aiding spells of protection and blessings for travel. Today, it is still a popular first aid remedy, containing the chemical allantoin which is said to speed up the replacement of body cells. This speeds up the healing of tissue and the closing of wounds, and aids in mending bones just as it has since ancient times. Many herbalists also use it to minimize the opportunity of infection and reduce scarring. Recent studies have resulted in concerns about liver damage from Comfrey`s use, however.
