Have you heard this before? I just read an article that said people who cut up an onion and put chunks of them around the house do not get the flu, or don't get it as bad. They absorb the bacteria. This is why we get food poisoning from potato salad (not the mayo as we supposed according to them) onions that are cut and left out actually absorb the yuck out of the air and help prevent people from getting flu and colds that are caused by bacteria. Has anyone else ever heard of this? It's such a simple solution.. I'm thinking of trying it - but I am skeptical!
