Abstract: In Thailand, traditional plant-based medicines have always been used to treat gastrointestinal ailments, including gastritis, peptic ulcer disease (PUD) and diarrhea. Since Helicobacter pylori (HP) is an etiological agent of PUD, we have used an ethnomedical approach for screening plant extracts as potential treatments for HP infections, including over 20 species from Thailand. International Memoranda of Agreement were established between UIC and Mahidol University in Thailand. Medicinal plants were collected, identified and extracted. Susceptibility testing was performed with 15 HP strains using the agar dilution procedure guidelines of the Clinical and Laboratory Standards Institute. In vivo studies included evaluating bacterial load, as well as acute and chronic inflammation in HP-infected Mongolian gerbils. Extracts of Curcuma longa L. and Boesenbergia rotunda (L.) Mansf. significantly reduced HP-induced gastric lesions, as assessed both macroscopically and microscopically in Mongolian gerbils. The treatments reduced acute and/or chronic inflammation in a prevention model of HP-induced gastritis.
