I started oil pulling in October and enjoyed immediate positive results. The oil that I used was Caprol (caprilic acid in olive oil).
For years I have held this same oil in my mouth and then swallowed it. I did this to relieve my burning tongue due to candida overgrowth. It did stop my tongue from burning but did not give me the wonderful results I get from spitting the oil out.
I could not believe it... all those years of nearly getting it right. I was pulling out the toxins and putting them back in.
Now, when I swallow oil on purpose, I do not hold it in my mouth for very long.
