I started Oil Pulling about six months ago after reading about it and watching some videos on YouTube.
I use Organic Sesame Oil, 1 T, 15-20 minutes. When I first heard about it, it was the "white teeth" that motivated me, and I was doing it almost daily. According to the info I read, when I googled it, there are other benefits as well. It seems to be controversial, like about everything these days, not a surprise.
Anyway, I had a "gut sense" that almost daily was too often. Now I Oil Pull two to three times a week.
I do notice my teeth are becoming whiter.
Another thing that I've noticed is that from time to time I spit up those white, bad smelling "curds" which I didn't even know I had. Gross! I did a google search and they are called "tonsil stones" (of course, there is a fancier, scientific word).
I'll spare all the "google" details...but I would not be surprised if the tonsil stones are related to Lyme. And this is even more Gross!!–but I've heard these can also be a way that parasites are released from the body. I'm not sure whether to go parasites released--yuck OR parasites released--great!!
I did test positive for parasites...so...that's my experience.
