Watch it. I would ONLY trust Dr. Saul Pressman (Ozonetherapy yahoo groups) on advise with anything to do with ozone. You can say you're professor all you want, but if you aren't, you shouldn't be misleading the public and compromising their trust for starters. Anything to do with vaginal, rectal or bladder insufflations can have devastating physical repercussions. Only Dr. Saul Pressman.
