This is going to sound very strange but I just got an e-mail today which claims the if you cut an onion, slice off top and bottom, and put it in a bowl in your room, it will absorb all bacteria. Apparently, families used this method in 1918 during the flu and it seemed to work. Others state that they have tried it and it works. Nothing to lose! Try it. If it does work, please let me know and pass it on.
