Contact Saul Pressman. http://www.plasmafire.com/
and go to the 'oxygen therapy' forum in curezone.
Do research. I'd stay away from ozoneuniversity.com.
I had a friend that had a very bad experience with
the guy that runs it. Medically and financially.
I think Peter is his name. Saul is your guy. The best
way to learn is to read Ed McCabes's book "Flood your
Body with Oxygen'. He knows the most about it.
Ozone therapy is legal in 12 states in the US. I know
it is legal in NY, if you live near there. I can give
you MD names if you are interested.
