Ozone therapy (O3X) is a medical treatment that uses a mixture of oxygen-ozone (95%-0.05%-99.95% oxygen and ozone -5%) as a therapeutic agent to treat a broad spectrum of diseases. Because ozone has pharmacological receptors, its mechanism of action is indirect, through its mediators.

Ozone generators: within the EU, ozone generators must comply with the RoHS directives. The generator must produce medical grade ozone at 99.5% pure oxygen.

The device must be capable of producing oxygen-ozone therapy with an ozone concentration range between 1 g / NML and 80 micrograms / NML. No other substances must be present apart from o2 and o3.
