Here's a good one if you have any burn from Heat or chemical or road rash:
if you apply dry cornstarch to the burn and leave it for 10 minutes the burn will never hurt again. It won't sting, it won't pang, it won't ache. You will still have a hole in the skin and a sensitive area but no pain after 10 minutes.
It's a miracle. I've used it 50 times, even on third degree burns over my whole back when my shirt caught on fire at the stove and it was polyester and melted to my back.
It also works on chemical burns when I spilled turpentine down the front of me.
If my skin is ever burned by flame or heat all I have to do is cool it off with water dry it off and put cornstarch on it dry and just leave it on for 10 minutes dry cornstarch in for 10 minutes. All pain of the burn no matter if they are third degree or just little light burns you'll never be in any pain from the burn ever after you put cornstarch on it and just leave it dry for 10 minutes. I've been using it for 30 years.
