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.
Comfrey can also be grown indoors, in pots (1 to 5 gallon size) for a continuous harvest of fresh, small leaves. For this purpose best results are obtained by planting two-year or 3-to-4-year plants in the larger pots or 5- gallon buckets.omfrey can be planted spring, summer or fall, anytime the soil can be worked. In warmer climates, (Deep South and Southwest USA) it can be planted and the leaves harvested throughout the year. Comfrey grows best in USDA Hardiness Zones 3-9. But will grow almost anywhere.
