ozone is a powerful healing force. one woman on the oxygen forum here on curezone was healed from stage IV cancer with ozone therapy. ozone works by destroying pathogens, soothing inflammation, and giving your body the raw material it needs to heal itself.
most do ozone therapy by drinking ozonated water. however, you can get a high grade machine and can infuse the ozone gas directly into the body. for men the ear and the anus are the two orofices that can recieve direct ozone insufflation.
i have personally never heard of any one trying to treat tinnitus with ozone insufflation, so you would be on the cutting edge. but i have heard that ear insufflatio of ozone has resulted in lots of drainage from the ears and then much sharper hearing and a feeling of clear headedness and the elminination of "brain fog." so i do think its at least worthwhile to investigate and look into it.
there are some very knowledgable people on the oxygen forum who can help you out with machines and technical questions.
