Hi Laughingrrrl. I have done my first oil pulling with very good results!{I used sunflower oil} And I also notice, that the results last. Anyhow, I have done a microscopic assessment. I have found some interesting bacteria. They "appear" to be of the gram neg. kind. They are coccus and small. But they appear to be active {or} pathogenic. I have also found yeast-type cells, and a few oocysts[surprised they are surviving in oil]. Most rod bacteria--the ones present-- looked inactive. They were long and splinter like. And the rest were run-of-the-mill epithelial and plasma cells, as well as normal bacteria. Shroom
