I heard about this too but you have to take out the garbage first. This treatment alone has not worked for most CZers who tried it from my research. My relative had the cavitation surgery and I saw the brown muck that came out from deep, deep, in the jaw and that just cannot be dealt with through injections alone. That garbage had to be taken out and then the area was treated/flushed with ozone, and incredible health improvement followed thank goodness!
