Ozone therapy: clinical and basic evidence of its therapeutic potential

Ozone has recently been subjected to criticism and emphasis in relation to clinical efficacy and toxicity, respectively. Without a doubt, ozone, in common with oxygen itself, is one of the most potent oxidants. Ozone is considered one of the major pollutants in urban areas. Nevertheless, increasingly widespread use lately has highlighted the potential benefits as a therapeutic agent when used according to well-defined and safe protocols. Basic studies conducted following rigorous scientific and ethical criteria have been proposed for scientific discussion. This paper concerns original data on an in vivo model of Parkinson's disease and published data on the effect of low ozone doses with any risk of toxicity excluded with the concentrations commonly used in medical applications.
