I've read many times on the internet that rubbing Vick's vapor rub on the bottom of your feet and wearing socks over it stops coughing.
It sounds absurd, to me, but I know that there are things having to do with foot reflexology/etc, that actually do work with ailments elsewhere in the body, and I figure this might be similar.
1) Have you ever tried this method? Did it work?
2) HOW does it work?
