What it is
A resin from the Mediterranean mastic tree with anti-inflammatory and antimicrobial properties. Clinical trials show it kills H. pylori and improves symptoms of functional dyspepsia and acid reflux. One RCT found it healed duodenal ulcers comparably to antacids. Main downside: relatively high cost compared to standard treatments.
