This post is to share a surperb burn remedy with you. In my 70 years I've found nothing that comes close enough to stand in it's shadows.
Pure lard with flowers of sulpher mixed in at room temperature or slightly warmer. Don't heat the lard hot or it will cake quite rapidly. Mix up a batch and keep it frozen so the lard doesn't turn rancid. (Probably wouldn't hurt performance even if it did though.) You can purchase flowers of sulpher from any drug store, though some may have to order for you. It is just pure sulpher ground VERY fine. (The remedy is ultra cheap.)
Here's how good the remedy is. Some years ago when my fair lady and I returned from a horse ride we found the house so full of smoke I couldn't see to walk but had to feel my way to the kitchen range. (She remembered instantly on seeing the smoke that she had left a pot of beans going with the electric range on high.) When I got to the stove I could see the bottom of the pan glowing red hot. I picked up the pan and when I turned, the aluminum clad bottom, which was completely molten, dropped and splattered across the narrow walk between frig and cabinet island. My only choice was to walk through a 6 foot stretch of glowing molten aluminum blobs,with stocking feet. Use your best imagination and if you haven't had a similar burn, on both feet, you won't be able to imagine the pain thresh hold!
My wife smeared my feet with the above remedy and slipped some cotton socks on to hold the sloppy, beautiful stuff in place. The pain stopped completely in a few minutes, so I pulled my boots on and went out to cut molds the rest of the day, and every day till my feet were healed. I wasn't being tough guy! My feet didn't hurt at all, and they healed VERY rapidly!
Don't be without a jar of it in your freezer. We just had a neighbor lady get burned real bad and didn't have any, so I made a rush trip to town to fix her up. Do it now, because you may have to hit several drug stores to get the flowers of sulpher. By the way. The sulpher has unlimited shelf life when left dry in the bottle. I only had to get lard on this rush trip.
