Ozono, Contaminación Ambiental y la Medicina Basada en Evidencias
The main features of ozone are reviewed. Its protecting role in the stratosphere, as a polluting agent in the troposphere and essential ingredient in unproven therapies. The following elements are discussed in detail: ozone in the stratosphere and troposphere; as a polluting agent; synthesis, storage, measurement and disinfectant capacity; Evidence-Based Medicine (MBE) and ozone therapies; ozone in Mexico and Cuba. Stratospheric ozone protects animal and vegetal life from ultraviolet solar radiation, while the tropospheric is an active pollutant, harmful to health. In spite of the bulky amount of papers published on the subject, and in agreement with present criteria on clinical trials and the MBE, there are no proofs recognized by the scientific community, nor valid theoretical basis, endorsing the efficacy of ozone as a drug.
