This is What Happens When You Put Cut Up Onions in Your Socks While You Sleep- You have no idea how excited I was to see this!! I swear by this method, it really works and helps your body. Growing up anytime we were sick or had fevers our mother put onions in our socks, across our chests and our forehead to help get rid of the fever and IT WORKS!! Now I'm not saying you don't stink afterwards (lol) but that's what showers are for. Next time you have a fever seriously try this.
