I have rough feet. I am not sure why? Maybe it is because they carry too much weight around. Maybe it is because I don't wear socks often enough. Maybe it is because I have a disease called 'crusty foot'...well that's what my husband calls it!  At any rate, whatever it is, when I use foot lotion on my feet, I prefer the ones with a strong mint base to them. The cooling effect feels awesome. And it turns out that an ancient minty concoction is being revisited as a pain killer!  Those Greeks were pretty smart!  Here is the rest of the story about a new pain killer that will be used externally and works better than morphine without the side effects (for arthritis and diseases affecting nerve endings).
