Is ozone harmful to human body?
The branch point of the ozone is 0.01P. P. M. . But the mankind can only smell it with the concentration between 0.03-0. 04P. P. M.. The ozone can carry on the chemical reactions with all saturation organic matter at very low speed in air under the normal temperature.

The pure water without nitrogen and oxygen compounds is nonpoisonous, whose concentration even may be a little high. Early in 1949, many Japanese doctors and pharmacy doctors made contests in white mouse, the rabbit and monkey with pure ozone of no less than 99.9% concentration. Years later, it is proved that ozone not only was nonpoisonous but also made the animals develop faster and better with stronger propagate ability instead. And it has been confirmed later by scientists and doctors that injecting right amount of pure ozone from hype or into the skin and muscle is completely harmless and that pure ozone can purify blood rapidly, increase the amount of erythrocyte and leukocyte, and receive the cell’s metabolism function. We can see from the experimental result that ozone is certain to build body and dispel varieties of diseases difficult to cure. It is believed that people will benefit a lot from ozone in the near future.
