Comfrey leaves and stems infused into olive oil has used by fellow herbalists for direct healing of skin and muscle tissue from past wounds, sprains and breaks. One of its folkloric, common names is “knitbone,” precisely for this very reason. Apply to closed skin, only. If the wound is fresh or open, you may apply it carefully on the skin surrounding the opening.
A study or two has noted the high, “toxic” levels to humans of pyrrolizidine alkaloids, contained in Comfrey and other plants, which can adversely affect the liver. Note that this study (a) tested comfrey as it was ingested as a tea, which therefore is not relevant to an external application, and (b) tested the alkaloid in an environment which would prove remarkably difficult – if not impossible – for any one human to consume. That is, the alkaloid was extracted from the whole herb and the extract was intensified several hundred times its normal potency. For more information, I recommend the following summary published by Subhuti Dharmananda, Ph.D., Director, Institute for Traditional Medicine, Portland, Oregon, “Safety Issues Affecting Herbs: Pyrrolizidine Alkaloids” at < http://www.itmonline.org/arts/pas.htm >
