I came across this article and it is nicely written and one can even go back and read Hahnemann's original thoughts on how to treat burns. He did not suffer fools lightly and his letter is a response to a Doctor who had prescribed cold applications to burns. It seems that actually hot water or hot flame is better for a burn and seems to encourage the healing. It is worth knowing or at least in my life there have been times when knowing how to treat a burn would have been good to know. Have a look as it is well documented.
