How many of you do oil pulling?

I haven't actually tried it myself but my friend does it and has recommended it to me. She used to have extremely bad excema on her arms, face and the backs of her knees and it has all cleared up, her teeth have also whitened a lot and her gums are healthier, and she has lost weight. I want to try it to help my KP but from doing some research on the internet (there is lots out there about it)I have found out it can even help things such as cancer or tumours.

I just recently knew about this info when a friend of mine told me about it. I was amazed that this is practiced by practically everyone from around the world. Althoug this I think started in India it is widely practiced by many non Indian also. My friend said she might start it to see if they will be effective for her skin allergies. As for me, I might use it if I find it to be working on her at all.
