When the body is deficient in redox enzymes (such as glutathione) the surge of oxidation promoted by oxidative therapy is exactly the ticket, as it provokes a surge of the CREATION of these redox enzymes. This creation of redox enzymes is the other end of ozone therapy, and it's as beneficial as the oxidative end.
I recommend that people ensure they have glutathione precursors in their diet before they undertake ozone therapy. The undenatured whey and selenium I suggest are chemotherapeutic even on their own anyway.
