Dr. Shook wrote the following:
"It does not seem to matter much which part of the body is broken, either internally or externally; comfrey will heal it quickly. It is a great cell proliferant or new cell grower, it grows new flesh and bone alike, stops hemorrhage, and is wonderful for coughs, soothing and healing the inflamed tissues in a most remarkable manner." Comfrey is one of the finest healers for the respiratory system, especially where there is hemorrhage of the lungs; it has saved thousands of lives. The root has been used reputably as both a tonic and a vulnerary from very ancient times up to the present. The root and leaves are most beneficial as a poultice in healing any obstinate or ulcerous wound. Comfrey forms an ingredient in a large number of herbal preparations, and it may be given wherever a mucilaginous or demulcent medicine is required. The chief healing element in comfrey is allantoin, a cell proliferant (promotes granulation and formation of epithelial cells in the roots and leaves)."
