When I was 4, I severely burned my hand on an open oven door. My grandma immediately put my hand down in the crock of flour--it was cool, no air could touch it. She made me keep it there for hours (seemed like it, anyway). No blistering at all. By the time my dad got home with the car to head for the hospital, I was ok enough to not need the trip.
OK so I burned my hand taking a skillet out of the oven set on 400 degrees around seven pm...it is now 1130 pm...and I've had to constantly keep ice on it to numb the pain...it has already blistered....I couldn't sleep because once the ice melted the pain immediately came back..so I started browsing the web for a remedy...in a new apartment and didn't have access to baking soda so I randomly tried flour instead...can't compare to baking soda but it most definitely has made the burn much more bearable...I can actually sleep with this mild discomfort...although the burn i's on the palm of my hand...I filled a bag with the flour paste and put a sock over it
A friend recommended flour for burns and I tried it when I burned my hand when hot oil splattered and it works! I keep a small jar of white flour in refrigerator and use it whenever I get a burn.
