Andreas Moritz says these Oxygen Cleansers help to really clean up old debris and waste along the colon walls. I figure, if they can really get in there to sweep away more crap,(than a regular colon cleanser) possibly sweep away parasites that are hidden deep, that I'll do it, sure why not? His book is great, and I am taking a lot of suggestions in there. I can't afford to do colonics, so by doing this and enemas, I'm able to do more. I take it at night, not a full dosage yet, because it makes me very gassy. but i figure it's doing it's job.
