The essential oils certainly help. I have Doterra tea tree and i just rub it on my hands and around my mouth and nose. It kills everything. Also have you ever heard of chlorine dioxide solution? My family has had that inour medicine cabinet for about 4 years now and it is impossible for the flu to even come anywhere near us with that stuff. Even if one of us gets sick we knock it out in less than 24 hours no matter what. Feel better!
