I can completely attest to everything the previous poster said. My husband's breath was horrible. When I say, was, I'm talking past....! Do you have any digestive problems? Gas, or acid reflux or bowel habits? That's a sure sign right there. I think my husband had parasites, so we did Colonix. Instead of the fiber, we used Oxypowder (only available on the web). I simply cannot tell you how well all this worked, including the liver flush, which, as weird as it looks, is fantastic.
The oil swishing is great. Here is the best website I could find on it (all the rest are in russian). I prefer the sunflower oil over the sesame. Don't take too much in your mouth at once, it expands with all the salvia.
