This study was designed to evaluate the effects of Korean medicine therapy(Banhasasim-tang) on a peptic ulcer patient. Three peptic ulcer patients with symptoms of epigastric pain, heartburn and nausea, were treated with Banhasasim-tang. The progress was evaluated with the Visual analogue scale. In all three cases, after 3 weeks of treatment with Banhasasim-tang, the patient's symptom of epigastric pain, heartburn and nausea evaluated with the Visual analogue scale improved. This study suggests that Korean medicine(Banhasasim-tang) could be effective in the treatment of peptic ulcer.
