The effect of aqueous extract of
Moringa oleifera
leaf was studied on experimentally induced gastric ulceration in rats. Pretreatment with extract 200, 300 and 400 mg/kg bw reduced the characteristic lesions induced by indomethacin compared to untreated control group in a dose dependent manner. The effects observed could be due to the action of one or more of the phytochemicals present in the leaf extract.
