This study tested a traditional Chinese herbal medicine called Houtou Jianweiling Tablet against omeprazole, a common stomach medication, for treating chronic stomach inflammation. The herbal tablet worked just as well as the conventional drug at relieving stomach pain, bloating, and reducing harmful bacteria, while being very safe with almost no side effects. This suggests that people with mild to moderate stomach inflammation could use this natural herbal alternative instead of, or alongside, conventional medications.
