There are at least two strengths of ozonated olive oil products on the market. The lightly ozonated olive oil can be used internally or externally. Fully ozonated olive oil or any other type of fully ozonated oil should not be ingested except in extremely small quantities. You can read about ozonation of oils at http://www.ozonatedoilonline.com/ozonatedoilarticles.html
