The type of application, the application range, and the dosage of a medical ozone/oxygen mixture (prepared from the purest oxygen and used in a concentration between 1 and 100 g/mL) have been derived principally from its employment in the preparation of drinking water and the regeneration of liquid waste. This is in the light of its bactericidal and fungicidal properties – which in the clinical field also comes under the heading of disinfection – in addition to the virucidal and thus the overall sterilizing property of ozone. Furthermore, within the biological system, different properties become manifest which may be summarized as its positive effect on blood circulation, and as expressed by an activation of oxygen transportation mechanisms and an improvement of active biological oxygen utilization.
