They show maps of gaping holes in the ozone layer. They teach us that ozone in the sky protects us from cancer-causing ultraviolet rays in sunlight, and that we get skin cancer when holes in the ozone layer fail to block those rays. That makes ozone a good player. Many people do not seem to realize that ozone in pure form and ozone mixed with pollutants behave differently. Ozone is an oxidant.
Ozone is an antioxidant.

So the proponents of ozone therapy are steadfast in their defense of the empirical value of their chosen therapy. For several years, I sided with the chemists on the above issue.
