I think there's a difference between caution (which should be extreme with either big pharma OR alternative medicine) and paranoia. Big pharma has proven that its research can't be trusted to be undoctored (pun unintended but...). Alternative medicine doesn't have the resources for the kind of research that would help consumers make better informed decisions given the lack of institutional support.
I love your enthusiasm, but I think in these forums we should all remember to urge caution to the newbies. Few if any of us understand this stuff beyond our own limited experiences.
My exact concern given the blue skin condition is that maybe this stuff doesn't get expelled from the system adequately. And because the ingestion of most metals beyond trace quantities is generally harmful in some way to the body.
But hey, this is the oil pulling forum and I took this thing way off topic. To go full circle, I tried some Oregano Oil in with my Flax Seed Oil and didn't mind the taste at all. It's probably a great combination to ward off gum diseases.
