If you rub vinegar, garlic, or onion on the bottom of you foot, you taste it in your mouth.  Why is that?  Additionally, if you rub Vicks Vapo Rub on the bottom of your feet or your child's feet and cover with socks when they are super congested before bed then it helps them breathe better.  Why is that?
