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.
