Evaluation of gastric anti-ulcer activity of fixed oil of <i>Ocimum basilicum </i>Linn. and its possible mechanism of action

253-257Fixed oil of O. basilicum was found to possess significant antiulcer activity against aspirin, indomethacin, alcohol, histamine, reserpine, serotonin and stress-induced ulceration in experimental animal models. Significant inhibition was also observed in aspirin-induced gastric ulceration and secretion in pylorus ligated rats. The lipoxygenase inhibiting, histamine antagonistic and antisecretory effects of the oil could probably contribute towards antiulcer activity. O. basilicum fixed oil may be considered to be a drug of natural origin which possesses both antiinflammatory and anti-ulcer activity
