FDA and Ozone

I was on the FDA website and wanted to see what they say regarding ozone therapy. The link below is the first thing that came up:

Apparently, the case resulted in the death of the patient who was treated with ozone. Now, I am not arguing for or against the FDA, but I just wanted to get a feeling of what you guys think? I understand that who really knows what happened and how much treatment/ozone was applied. The FDA claims that ozone use for medical purposes is toxic to the body. And that the amount of concentration needed to actually help an illness is too much an average persons body can handle.
HV, what do you think? As compared to chemotherapy, which has a rather low success rate, why is the FDA so against alternative treatments? Tweet
