I had not heard of flour for burns but bet it is good also.
But, there is an ointment called FOILE comes in a
bright yellow tube - wonderful, put it on as soon as the burn is done and you get great results. If your drug store does not carrry it, can order. I live in a small town with only one pharmacy, I believe they call them that now days, but a great one. This drug store carries a lot of the older stuff that was used in past years. Some of the older items they have to order but it is in the next day. SOME OF THE OLDER DAYS WERE GREAT. Hope your burn is almost well.
