Over centuries, comfrey was cultivated in Asia, Europe, and the United Kingdom as a vegetable and herbal medicine. Its early common names – “knitbone” or “boneset”- reflect its historical use in treating sprains, bruises, or bone fractures. Comfrey has unfurling cymes of beautiful edible purple flowers that can be used in salads or for garnishes.
