In 1991, Dr Michael Carpendale and his colleagues at the
Veterans Administration Hospital in San Francisco showed that
HIV could be 99 per cent inactivated using only 0.5 mcg ozone/mL
of human blood, and completely inactivated by concentrations of
4 mcg/mL of human blood, neither of which were harmful to
healthy cells (Antiviral Res, 1991; 16: 281-92). Early studies
by the team had indicated that ozone could boost T-cell counts
and eliminate infection for more than five years (Ozone in
Medicine: Proceedings of the 11th Ozone World Congress,
Stamford, Conn: International Ozone Association, 1993). Another
American study in vitro found that ozone completely deactivated
a cultured cell medium containing HIV-1 without causing
significant damage to non infected cells (Blood, 1991; 78:
1882).At Moscow's Institute of Virology, scientists used a
concentration of 4 mg/mL of ozone on an HIV infected culture.
Within minutes, the cell containing the virus had decomposed and
died (Kornilaeva GV et al, in Ozone in Biology a
