Sunflower expeller pressed! It ran about 7 bucks for 16 oz (not bad). I really really wanted the oil of oregano, as I've ended use of regular toothpaste. However, it was $28 for a few ounces and out of my financial reach! (I really pulled my own teeth, so to speak, just to purchase Dr. Clarkia ).
So far so good! While my teeth haven't been horribly discolored (even from smoking), they certainly ARE brighter. I also like the idea of potentially negating some of my past negligence (gums). All in all, I'm primarily interested in pulling toxins and the results of doing so.
