SYNOPSIS: Individuals having peptic ulcer disease positive for Helicobacter pylori infection (diagnosed by endoscopy and biopsy with positive rapid urease test) were treated with either traditional quadruple therapy or quadruple therapy with licorice as a substitution for bismuth subsalicylate. After 4 weeks of treatment, eradication of H. pylori infection was comparable in both groups.
