It is created artificially as the result of ultraviolet light acting on oxygen to break up and recombine as threesomes. Ozone destroys algae, viruses, bacteria, and fungi on contact and it breaks down harmful chemicals into simpler less damaging molecules.
Ozone kills microorganisms by rupturing their cell walls.
Healthy cells are not damaged because of their self protective mechanisms. Ozone has a half life of 20 minutes and thus should be used within the first 5-10 minutes to assure its strength. It can cause an initial drop in energy and feeling 'sickly' due to the die-off of pathogens it killed. It is especially damaging to cancerous cells. Ozone activates both monocytes and lymphocytes.
