I have heard of it, and I have done it. It actually is a pretty good practice if you have the time for it.
It's not as hard as you think to not swallow it. You swish it around, and in the beginning you might only make it 5 minutes or so before it becomes thin and you can't stand it being in your mouth any more. Then spit it out! Spit in the comode or it will make your drain stink. Rinse your mouth well after. When you spit with will be all white and frothy. It is actually pulling the toxins from your blood. I believe your are suppose to do it for 20 minutes because that's how long it take all your blood to circulate through the vain under your tongue.
If you do it everyday for several weeks you will see brighter white teeth, less bleeding gums and more renued energy. Others have witnessed other benifits but those are the ones I experienced.
Give it a try, it doesn't hurt! The first time I did it I got an amazing burst of energy and my teeth felt sooo smooth.
