I've done/doing IV ozone. That's MAH and it's the most common type of ozone therapy that Lyme patients use.
This article explains a bit about
the different ways it can be done. Ignore the ten pass portion as that's rarely done and you'd need to be deep into treatment and have done A LOT of ozone to handle that.
thepowerofozone.com/ozone-high-dose-10-pass/Ozone has helped me a lot. Almost all the ozone I've done has been hyberbaric and it's my personal opinion that makes a big difference. The one round I did that was Normobaric, that LLND mixed in a high level of ozone and passed my blood through UVB before it was but back into me.
I didn't start ozone until I'd been treating almost two years. I don't know if I could have handled it before then or gotten the same benefits.
