I noticed a wart growing on the bottom of my foot last winter. Old wive's tale or not, if you have a cold, before you to bed at night, you put Vicks on the bottom of your feet and put on a pair of socks. I had a heck of a cold last winter so greased my feet up and eventually the cold and the wart went away! I read somewhere that people also use Vicks to control athlete's foot, too!
