The power of Vicks VapoRub
According to many hacks that circulate on the internet, if you put Vicks VapoRub or potatoes, onions or other vegetables on your feet when you are sick you will feel better and cure a potential cough, but unfortunately, this trick does not work.
“Putting VapoRub on your feet, under your socks, is the least effective place to put it for cough relief,” Johnson said. “Just use it as instructed. It does help, especially when combined with a warm, steamy shower.”
