that place is only ozonating a small portion of the blood and then re-injecting that back into you.
i prepared myself by taking Colloidal Silver internally to strengthen the response to the oxygen and i brought some glutathione cream and rubbed that over my liver area a few times after the treatment.
i had a syringe the size of a turkey baster filled with ozone and set into a machine that plunged it at a slow meter as it was forced into my arm. he did that twice. i got a months worth of oxygen all at once. it cured the infection i had - systemic staph bacilli. instantly over. then the silver and everything worked as well when i got up on step of the oxygen wave. i was so deoxygenated that nothing was working. i am cutting back my smoking as a result.
a study of all the things free oxygen burns up in the body would all be good things to consider supplementing.
there are other ways to oxygenate. drinking ozonated water or hydrogen peroxide can yield great results.
