Currently, there are 14 countries where ozone therapy has been regularized, either throughout the country or in some parts of it.
However, the undertaking isn’t considered a viable treatment option by certain government-regulating agencies, including the U.S. Food and Drug Administration (FDA), which prohibits the application of ozone therapy.
Ozone Therapy and the Controversies Surrounding It
As medical researchers persistently strive to identify various methods for treating ailments, such efforts can often be unusual and controversial—ozone therapy being an example.
The ozone substance is a variation of the standard oxygen gas, which people breathe to survive. It was discovered in 1785 by Dutch physicist Martin van Marum (1750-1837) and manufactured in May 1840 by the German chemist Christian Friedrich Schönbein (1799-1868).
Ozone is said to be dangerous when inhaled. This gas is known to cause respiratory symptoms such as wheezing, coughing, irritated lung lining, sore throat, and permanent lung damage, especially after excessive exposure.
The FDA prohibits ozone therapy on the basis that it’s a potentially harmful substance, and further research is needed before the medical community can safely declare it an acceptable treatment option.
Regardless of these concerns, certain aspects of the scientific community maintain that ozone can provide hypothetically significant health benefits when administered through alternative methods. Such methods include direct tissue entry, intramuscularly, and intravenously.
Therapeutic researchers suggest that ozone therapy is relatively safe and effective in remediating ailments like cardiovascular problems, lung conditions, wounds, liver issues, and cancer.

History has it that it’s been difficult for ozone therapy to have a substantial manifestation on the global medical agendas. However, the gradual rising use of ozone therapy, mainly in Germany and the former Soviet Union from the 1960s, has provoked renewed interest in the controlled use of ozone therapy following adopted protocols.
Ozone therapy has been emerging in various European states, mainly in Italy, Spain, and Cuba, where it’s reinforced by the world’s only research foundation in the medical ozone therapy. China became another state where the treatment has had some importance after its introduction in 2000.
Today we can definitely say that the use of ozone therapy is increasing in different countries as the analysis for its regularization is still ongoing. The number of ozone therapists exceeds 30 000, where Germany leads with 11,000 practitioners, China is next with 5,000, and Russia comes third with 3,500 professionals.
