Anal insufflation without oxygen, just ozonated air...

I see sites saying not to do ozone anal insufflation with anything but pure oxygen. But you can't even get pure oxygen w/o a prescription. Also, I wonder why regular air is a problem anyway. I breath air. I use regular air to ozonate water I drink. Of course pure oxygen does seem like the ideal choice, but I wonder if regular ozonated air really is harmful, as some seem to suggest. Tweet
