Comfrey leaf has a long history of use for its beneficial properties in topical preparations throughout traditional Western herbalism. Poultices have commonly been applied externally to speed the healing of broken bones or torn ligaments because of its ability to increase cell proliferation. One of its common names is Knitbone.
Comfrey leaf has been used since Roman times, dating back thousands of years. This herb has been utilized in folk medicine throughout Europe and North America and has been widely cultivated.
Much debate surrounds the safety of comfrey due to various parts and preparations containing potentially toxic alkaloids. It is important to understand that the part used, species, and time of harvest all come in to play when determining the safety of this herb. A large body of traditional use supports its safety and efficacy if used intelligently and cautiously.
Renowned herbalist Susun Weed says “Comfrey (Symphytum) leaf is free of the compounds (PAs) found in the root that can damage the liver.” She drinks comfrey leaf tea on a daily basis.
