How safe is medical ozone?
Ozone is safer than most medications or medical therapies
When used properly, ozone is completely safe. A German study done in the 1980s evaluated the incidence of side effects in over 5 million ozone treatments given by health practitioners. The study found an astonishingly low level of only 40 incidences of side effects, or less than 1 in 100,000. Ozone’s safety record is much better than that of medication or most other medical therapies. Direct inhalation of ozone should be avoided, however, as it is irritating to the lungs.
