The effect of comfrey was known to Hildegard von Bingen (11th century AD) already. Broken bones, wounds or ulcers were treated with comfrey root compresses. The allantoin that it contains liquefies pus and makes new tissue cells (granulation). According to efficacy studies, the analgesic, anti-inflammatory and anti-swelling effects were clearly visible in acute ankle strains when compared to placebo treatments.Further studies with comfrey ointment proved an effect that is absolutely comparable with that of diclofenac. The efficacy of comfrey root ointment in treating bruising and sprains was also demonstrated in a study of 300 children, with the added benefit of being well tolerated.
