My friend sent this to me via email yesterday...she said it really works??!!! It would be worth a try!!!! 
VICKS VAPORUB...TRY IT, IT WORKS
I wish I'd known this when my family was Young during winter colds and coughs.
I am going to try it myself.
Share with young Parents.
Isn't life strange.
When we had a Lecture on Essential Oils, they told us how The foot soles
can absorb oils.
Their example: Put garlic on your feet and within 20
minutes you can 'taste' it.
Some of us have used Vicks Vaporub for years for
everything from chapped lips to sore toes and many
body parts in between.
But I've never heard of this. And don't laugh, it
works 100% of the time although the scientists
at the Canada Research Council (who discovered it)
aren't sure why.
To stop night-time coughing in a child (or adult as
we found out personally), put Vicks Vaporub generously
on the bottom of the feet at bedtime, then cover
with socks.
Even persistent, heavy, deep coughing will stop in
about 5 minutes and stay stopped for many, many
hours of relief.
Works 100% of the time and is more effective in
children than even very strong prescription cough
medicines.
In addition it is extremely soothing and comforting
and they will sleep soundly.
I heard the head of the Canada Research Council
describe these findings on the part of their scientists
when they were investigating the effectiveness and
usage of prescription cough medicines in children as
compared to alternative therapies like acupressure.
Just happened to tune in A.M. Radio and picked up
this guy talking about why cough medicines in kids
often do more harm than good due to the chemical
makeup of these strong drugs; so, I listened.
It was a surprise finding and found to be more
effective than prescribed medicines for children at
bedtime, in addition to have a soothing and calming
effect on sick children who then went on to sleep
soundly.
Polly tried it on herself when she had a very deep
constant and persistent cough a few weeks ago and
it worked 100%!
She said that it felt like a warm blanket had enveloped
her, coughing stopped in a few minutes and believe me,
this was a deep, (incredibly annoying!) every few second uncontrollable cough, and she slept cough-free for hours
every night that she used it.
If you have grandchildren, pass it on.
If you end up sick, try it yourself and you will be
absolutely amazed by the effect.
