Abstract	AIM OF THE STUDY: Dodonaea viscosa Linn. (Sapindaceae) is used as a medicinal herb by the tribes of Shola forest regions of Western Ghats. It is used for headaches, backaches, stomach pain, piles and simple ulcers. The present study was performed to evaluate the gastroprotective effect and acute toxicity of this plant in various experimental models. MATERIALS AND METHODS: Studies were performed in two different models (ethanol and indomethacin induced gastric ulcer) in wistar rats. Gastric protection was evaluated by measuring the ulcer index, gastric glutathione assay, alkaline phosphate assay and histopathological studies. Gastric secretion studies were done by pyloric ligation experiment. RESULTS AND CONCLUSIONS: Water and ethanol extract (500 mg/kg body weight) showed moderate activity compared to hexane extract. Hexane extract of Dodonaea viscosa dose dependently inhibited ethanol induced gastric lesions, causing 90% protection at 500 mg/kg, 81% protection at 250 mg/kg, and 70% protection at 125 mg/kg and it also dose dependently inhibited indomethacin induced gastric lesions, causing 92% protection at 500 mg/kg, 77% protection at 250 mg/kg, and 52% protection at 125 mg/kg. The various degrees of inhibition were statistically significant (p
