Has anyone tried this for IBS, GERD, gastritis etc. I have lots of stomach related problems and have posted on various forums as never really sure where I fit in. I have been having burning sensations in stomach all over midriff area under ribs which is not my usual feeling with IBS and GERD. Did wonder if I have gastritis but GP thinks it is H Pylori and has asked me to come off my PPI for 2 weeks, this is proving hard as I have been on them for over 12 years now. So went onto google and came across mastic gum, brought some yesterday and have started on them, no change yet but probably too early. They are pretty expensive so hope they are no another overrated product that doesn't work. Not keen to have tons of anti-biotics if it is pylori as that is what causes my pains in the first place. Any one tried it and found it worked.
