a quick recipe for comfrey ointment, steep lots of ripped up leaves in warm not hot olive oil with a sprig of rosemary(for remembrance) for a gd few hrs, strain off and gently melt in sum beeswax until melted, pour into jars and allow to cool. it helps anything from cuts to burns or jut sore hands. i did a test years ago when i burnt the fingers on one hand, i treated two fingers with the comfrey and two with e45, the comfrey treated fingers healed much quicker. not scientific i know but hey it was enough for me. i also know of people who have successfully treated psoriasis and ecxzema with the same stuff. try a small area first, as with all home remedies.
