Comfrey has been cultivated as a green vegetable and has been used as an herbal medicine for more than 2,000 years. Comfrey's original name, knitbone, derives from the external use of poultices of its leaves and roots to heal burns, sprains, swelling, and bruises. In Western Europe, comfrey has been used topically for treating inflammatory disorders such as arthritis, gout, and thrombophlebitis, and internally for treating diarrhea.
Once comfrey starts growing, it doesn't stop until the first cold snap. In the winter the plants go dormant and a good layer of manure can be applied. To get further plants, push your spade through the middle of a plant and lever up a portion. Take root cuttings (about 2 inches long) and away you go again.
