One of the men who became p24 negative reported feeling better immediately afterwards but no sustained benefit six months later. The other said he probably felt better just because it was an opportunity for him to get away from work and his home for a while. Of the two men who were reported to become HIV PCR negative, one reported that he was not PCR negative but feels ozone has been beneficial in some way. The other man could not be contacted after repeated phone calls and messages. Ed McCabe is a journalist who lectures around the world promoting ozone therapy through his books and videos.
Safety remains to be the most important issue.
We have been told of two deaths that were a direct result of intravenous ozone therapy. One of these cases is currently under investigation. To date, there are no studies that can clearly demonstrate how ozone works. In addition, there are no human studies that have shown that ozone can be effective. Reports of people becoming HIV negative have not been confirmed.
