Gross appearance of the gastric mucosa in rats. a Rats pre-treated with 1ml/100g distilled water (ulcer control). Severe injuries are seen in the gastric mucosa: Hcl/ethanol produced extensive visible hemorrhagic necrosis of gastric mucosa. b & c Rats pre-treated with Maalox and Ranitidine (50 mg/kg) respectively: injuries to the gastric mucosa are milder compared to the injuries seen in the ulcer control rats. d & e Rats pre-treated with aqueous extract at doses 125 and 250 mg/kg respectively: moderate injuries are seen in the gastric mucosa, and the injuries decrease when the dose increase. f Rats pre-treated with aqueous extract at dose 500 mg/kg: no injuries are seen, so at this dose, the aqueous extract completely inhibits the gastric lesions induced by acidified ethanol. g, h & i Rats pre-treated with methanol extract at doses 125, 250 and 500 mg/kg: the injuries reduce with the increase of dose; hence, at 500 mg/kg few injuries are seen. The methanol extract reduces gastric lesions induced by acidified ethanol
