My 4 year old son has had a very bad cough lately.
I have never heard this before, bu apparently my wife has heard some old wives tale about vapor rub...apparently, there is some belief that rubbing vicks or some other vapor rub on their feet, then covering with socks, is some sort of magical way to reduce their cough.
I was more than skeptical. First, my understanding is that vapor rub is put on the chest to allow for the medicine to be inhaled...so trans-dermal delivery doesn't even seem plausible. Putting the vapor medicine as far as possible from your mouth and nose, and then covering them with socks seems like the typical sort of reverse logic used by "alternative" medicine advocates.
Also, the whole foot thing smacks of pseudoscience, like the toxic foot pads. And the belief that feet somehow absorb better than other skin makes no sense - I would think the opposite would be true, since the feet are probably thicker skinned with callouses as opposed to any other part of the body where skin is probably thinner.
Finally, if there were any validity, I would expect Vicks to market to that possibility. At the very least, a FAQ question on the topic. Frankly I would expect them to fund a study if they felt it was possible.
Anyway, I found this quite funny and thought I would share it as idea for the show. I had never heard of this, and was surprised to find that all the neighborhood mothers seemed to share a common belief in its effectiveness.
