If you know or are convinced you have H pylori, you can try the following:
Jarrow sells "Mastic Gum 500"-- 500 mg capsules. Empty a capsule (or half of 1) into some hot Licorice Root tea and drink it. I did that for about a week. Something tells me if you really have the H p. you'll notice something. Or, if you happen to get the mastic gum rocks, which I also did, you can put them in a jar with a little olive oil for 2 weeks, swirling it around occasionally. They will dissolve and you will have, in essence, "mastic gum oil." Hat tip to HV.
