No but it is helping my acne. Oil pulling works I think by absorbing fat soluble toxins. You swish oil for about 20 minutes which is a workout in itself. As the blood circulates its toxins are dissolved in the oil in your mouth which eventually you spit out.
My theory is that doing this is doing what a liver normally does in your body. When it gets help in doing its normal functions through oil pulling it is free to do some additional clean up. My personal experience certainly makes me think so.
In any case it doesn't hurt to try. I mean you are just swishing edible oil in your mouth.
