Comfrey Salve

My father hurt his angle on Friday evening and it was so swollen that he could not walk on it. Saturday morning, the walk-in clinic had over an hour wait time, so he decided to use Comfrey Salve instead and go in to see his doctor on Monday. After using this salve for about day and half, by Sunday afternoon, he felt much better and his angle swollened a lot less and he was able to walk on that foot. He said that he would not need to go in on Monday anymore.
