[I can relate to all the dumb things, I believe I have done them all in my 78 years. I grab an egg and separate the white and yellow, slightly beat the white and spread on the burned area. You can do it several times. It works!]
Don't know if I would put egg white on an open burn or wound. The egg might be contaminated with samomella(sp?). Sure wouldn't want that on an open area. And for all I know the egg might carry other bugs like E. coli(sp?).
