Macroscopic appearance of the stomach of experimental rats submitted to ethanol-induced gastric ulcer in different groups showed that the normal control group exhibited an intact stomach without lesion (group A), ulcer control group showed extensive lesions to the gastric mucosa appears as elongated bands of hemorrhage (white arrow) (group B), reference control group pretreated with omeprazole at 20 mg/kg showed mild injuries to the gastric mucosa as opposed to group B (group C). Whereas, rats pretreated with zerumbone at 5 and 10 mg/kg, (group D and E, respectively) showed moderate to slight injuries to the gastric mucosa as opposed to group B (magnification: 1.8 x). (n = 6).
