Have you at all tried taking oregano oil internally to help get rid of the H. Pylori? The edible oregano oil, most health food stores sell it - don't get a cheap one though, strenghth is necessary and costs a bit. Good brand will cost at least $20 for a small dropper bottle. But you only take 2 or three drops in water at a time.
This strong type of oregano oil kills much more than olive leaf extract, and than most other anti-parasitical products do when it comes to the little bad guys like H Pylori.
I really feel you need to get rid of that before other steps will help.
