Someone asked about it.: Extracorporeal Blood Ozone Oxygenation.
At its root this is a way of getting ozone gas into the body. The idea is ozone stimulates 2,3 DPG enzymes that increase hemoglobin. The enzyme triggers more off-loading of the oxygen at the cellular level. Ozone can be injected IV. Or infused rectally. If an ozone-enema is used the gas goes to the liver. Same as if injected IV. The problem is ozone is an oxidant. If injected IV it can cause painful spasms in the chest. This is because the lungs have a small layer of anti-oxidants. Once that layer is reduced by ozone it starts attacking deeper tissues, bronchi and even lung alveoli. I've injected myself with ozone IV, SC and rectally. I wanted to see what the fuss was all about. What I found was ozone increased my athleticism. Temporarily my jogging speed went from 12 minutes per mile to 8 MPM.
It's a facebook site with ozone in the title.
