not sure how that works... something about an extra oxygen molecule? but if it were me, I'd save the money and use bentonite clay in an enema (does all of the above, anti-parasitic, healing etc plus helps eliminate heavy metals) or just add some food grade H2O2 (hydrogen peroxide) to the enema water to increase oxygen in the water. The extra oxygen molecule kills anaerobic bacteria and oxygenates, don't overdo it or it'll burn you but so will ozone.

you'd be amazed at how much more life a good colon cleansing routine will give you. either way you will have to get to it at some point if you want to be well. The sewer requires cleaning after so many years of abuse, essentially... and it will keep you ill no matter how much money you spend on other things if you don't give attention to the matter.

anyway, me, I'd save the money for reasons stated above... being ill tends to devour my bank account, not help it grow.
