Symphytum officinale
Comfrey, knitbone. · Plant · Boraginaceae
Symphytum’s marked affinity with the bones in herbal medicine is also carried through to its focus in homeopathy. It is used to heal sprains and fractured or badly set bones, as well as to ease any pricking pain from old injuries to the bone, cartilage, and periosteum (the membrane surrounding the bone), or pain on the site of an amputation. Abscesses in the psoas muscle (which links the hip and the pelvis) and malignant bone tumors on the face may also be helped by Symphytum. In addition, the remedy is prescribed to treat painful eye injuries with strange sensations—for example, on closing the eyelids, the eyeballs may feel raised, although there is no visible sign of injury. There is frequently a marked tendency to rub the eyes and great difficulty in opening the eyelids.

Characteristics
Symphytum may be considered the orthopædic specific of herbal medicine. "The roots of Comfrey stamped, and the juice drunk with wine, helpeth those that spit blood and healeth all inward wounds and burstings. The same bruised and laid to in manner of a plaister, doth heal all fresh and green wounds, and are so glutinative, that it will solder and glue together meat that is chopped in pieces, seething in a pot, and make it in one lump" (Gerarde).
