Oxygen therapies are not generally considered to be the end all for ridding your body of parasites. It's excellent for bad bacteria, yeast, and general toxicity. And it might actually kill 'some' parasites. But probably not all. You should probably augment your ozone therapy with some other kinds of protocols for killing parasites (look at Hulda Clark information on parasites). For example, Wormwood , Black-Walnut hulls and cloves.
