You know, I think Oil Pulling has more de-toxifying effects than we realize. I mean, this group is just at the tip of the iceberg with it. After doing it for a number of months now, I'm still surprised at what it is doing for me, and to me.
I have really bad allergies right now (the West Coast just got way too much rain there at the end), and now everything is really really dry, and it's windy to boot. I have noticed, that I am totally clogged up in the morning, until I pull, and then I'm fairly unclogged for the rest of the day. I think it really does a number to the sinuses.
So, my belief is that yes, the oil pulling is having an effect.
