Did you know that you would be able to smell garlic on your breath  if you rub garlic oil on the sole of your feet?  That is because the oil was absorbed into your blood stream.  That is why I find foot soaks a wonderful and healing ritual.  I recommend a footbath when you feel a cold coming on, dancing too much, or general blah feeling.  To the warm water, I add cup of hydrogen peroxide and a hand full of sea salt. The soak is relaxing and it helps bring down inflammation.  Sometimes I brew peppermint tea with essential oil in the footbath. Using a footbath before bed aids in promoting a good night's rest.
