Peroxide Value (PV) measures the amount of active oxygen present per kg of product. Measuring this value is also critical to determine the quality and establish the therapeutic effect of each ozonized oil.
Hence, the evaluation process of the peroxide value should reliably follow the method recommended by the International Scientific Committee on Ozone Therapy (ISCO3), as per the Madrid Declaration on Ozone Therapy (2nd and 3rd Editions).
From a therapeutic point of view, the specifications about ozonized oils are defined on three levels:
- High (1200 PV)
The higher the peroxide value in the product, the greater its antimicrobial capacity, because of the greater release of peroxides – antiseptic action.
- Medium (600 PV)
Intermediate peroxide values simultaneously perform antiseptic action and promote cell cycle – enabling tissue proliferation in a hyper oxygenated environment.
- Low (400 PV)
The lower the peroxide value, the greater its regenerative capacity, because it has a greater healing activity, with enhanced action to induce the synthesis of growth factors and accelerate the cell cycle.
In other words, in inflammatory phases, it is advisable to use an ozonized oil with a high PV. In regeneration phases, an oil with a medium PV should be used, and in healing phases, an oil with a low PV.
