Explain to me scientifically how rubbing 'Vicks' on feet is actually meant to work??

A great book that covers a lot of this is: "How to Raise a Healthy Child in Spite of Your Doctor" by Robert S. Mendelsohn M.D.

A year or so ago i did a children's first aid course and was surpised to find that the 'vicks', baby oil and things alike are poisonous. I'd never rubbed 'vicks' on my boys but i had used the liquid version for the vapouriser. From now on if i use the vapouriser i only use water.
