A research group from Saudi Arabia studied the anti-ulcer properties of the salad herb rocket, also known as arugula (species Eruca sativa). They found that rocket extract possesses antisecretory, cytoprotective and anti-ulcer activities against experimentally-induced gastric lesions in rats. The anti-ulcer effect is possibly through prostaglandin mediated activity and/or through its anti-secretory and antioxidant properties.
