Yeah, they didn't have that at my hippie store. All they had without glycerin or silica was that tooth powder, and I'm not too keen on that stuff anymore. I made my own, using this recipe (sans DE and essential oils, plus xylitol) with calcium powder I bought at the hippie store. If you make it, she's not kidding about one part at a time with CO. Hers took 3, mine took 2.
