To me, people saying Oil pulling is healthy, fits in the same catagory of gimmicks. There are hundreds of such gimmicks. I don't have anything against it, it can't cause any harm, but sure can't do what people want to believe it can do for them. Or maybe it can, I have yet to be convinced.
I WILL GURANTEE YOU ALL THIS:
Give my kids a mouth full of olive oil and suggest they do this and after they SPIT IT OUT, they would run away crying and not trust any fool to put just anything in their mouths again.
Now my dogs would eat it, drinking or eating it makes sense when food rules are obeyed with such a thing.
