Objective To evaluate the antioxidant activity of the essential oil obtained from Rosmarinus officinalis (R. officinalis) in ethanol-induced gastric ulcer model in vivo. Methods The antioxidant properties of the essential oil obtained from R. officinalis were evaluated against gastric injury induced by absolute ethanol. Gastric tissues were prepared to enzymatic assays. The levels of glutathione, lipid peroxides, and the activities of glutathione peroxidase, superoxide dismutase and myeloperoxidase were measured. Results Ethanol produced severe hemorrhagic lesions in the stomach with ulcerative lesion of (140.2 ± 37.2) mm
