Singlet oxygen, O1 is a highly reactive, beneficial free radical that acts as a scavenger of other harmful free radicals. The oxygen combines with some of them to render them harmless, thereby protecting cells from damage. Healthy cells have enzymes that protect them from oxidation. These enzymes are glutathione peroxidase, superoxide dismutase, catalase, and reductase. Bacteria and viruses have no such enzyme protection and are therefore oxidized. By this elegant mechanism, ozone distinguishes between friends and foes and attacks only toxins, pathogens, and cells that have been damaged, weakened and infected.
The anti-oxidant products are gaining in popularity as nutritional supplements due to vigorous promotion. They are really free radical scavengers and enzyme enhancers. They have been shown to help protect marginally healthy cells from free radical damage. Superoxide dismutase in particular has helped reduce a variety of disorders; normally it is among the body's most plentiful enzymes. However, prolonged use of supplementary enzymes could tend to atrophy the body's ability to make these enzymes. In any case, it does not address the cause of the problem: oxygen starvation at the cellular level, which causes the cells to be too weak to make the enzymes that protect them; and toxins which prevent the free radical scavenging enzymes from doing their job.
The psychological consequence of attempting to convince people that their bodies are under constant attack is detrimental to good health. The limbic system, or midbrain, controls both the emotions and the immune system. We must never engender fear with terrorism regarding health, as is so often done by the media with their periodic waves of 'carcinogen panic' and 'free radical scares'. As Dr. Warburg stated clearly in 1966, this approach is detrimental to public health.
Medical ozone is completely safe and non-toxic to humans when generated by proper non-contaminating equipment and administered with proper protocols. As Prof. Halliwell has written, there has never been any proof that ozone causes free radical damage to the body. It has been shown to be completely safe even when a dosage many times greater than the proposed human dosage is administered."
