The gastric mucosa epithelial cell line, RGM 1, was pretreated with <jats:italic>Magnolia officinalis<\/jats:italic> water extract (0, 0.1, 1, 2, 5, or 10\u2009mg\/ml) and cultured in DMEM\/F12 medium (pH 7.4) for 2\u2009h and then in DMEM\/F12 medium (pH 4.0) for 10\u2009min. <jats:italic>Magnolia officinalis<\/jats:italic> water extract protected the cell viability and decreased reactive oxygen species formation by the acidic medium. In the <jats:italic>in vivo<\/jats:italic> experiment, <jats:italic>Magnolia officinalis<\/jats:italic> water extract (100\u2009mg\/kg) was administrated daily for 28\u2009days in ICR mice via oral gavage, and then Shay\u2019s ulcer surgical method was performed to induce gastric ulcers. We analyzed the pH value of stomach acid and the pathological section, inflammation, and cannabinoid receptor type 2 (CB2) cDNA levels of the stomach. <jats:italic>Magnolia officinalis<\/jats:italic> water extract not only enhanced the pH value of stomach acid but also ameliorated the ulcer index and inflammation and increased CB2 expression effectively. These results suggest that <jats:italic>Magnolia officinalis<\/jats:italic> water extract might be used to decrease the incidence of gastric ulcer.<\/jats:p>","DOI":"10.1155\/2023\/7901734","type":"journal-article","created":{"date-parts":[[2023,4,6]],"date-time":"2023-04-06T17:20:13Z","timestamp":1680801613000},"update-policy":"https:\/\/doi.org\/10.1002\/crossmark_policy","source":"Crossref","is-referenced-by-count":5,"title":["Efficiency
