Ozone therapy refers to the process of administering ozone into the body to treat a disease or wound. Ozone is a colorless gas made up of three atoms of oxygen (O3). Research has found that ozone may be used to treat medical conditions by enhancing the immune system. It may also be used for disinfection and to treat a range of diseases. When ozone comes into contact with body fluids, the resulting reactions form more proteins and red blood cells. This increases oxygen supply in the body, thereby improving its healing and functioning capabilities. Ozone therapy may also disrupt unhealthy processes in your body.
