Extracts of Benincasa hispida prevent development of experimental ulcers.
Benincasa hispida (B. hispida) is recommended in Ayurveda for the management of peptic ulcers. Therefore, anti-ulcerogenic activity of different extracts of B. hispida (fresh juice, supernatant and residue fraction of centrifuged juice, alcoholic and petroleum ether extract) were studied in aspirin plus restraint, swimming stress, indomethacin plus histamine and serotonin-induced ulcers in rats and mice. The oral feeding of different doses of the extract significantly reduced the ulcer index produced by various ulcerogens. The anti-ulcerogenic effect was dose-dependent in stress induced model of ulcer and not in other models. B. hispida probably has a CNS component in prevention of stress induced ulceration. However, antihistaminic, anti-cholinergic effects and prevention of disturbance in gastric micro-circulation as possible modes of action cannot be ruled out. Chronic toxicity studies carried out for 3 months revealed no deleterious effect of fresh juice of B. hispida on various hematological and biochemical parameters studied. Thus, extracts of B. hispida may be considered to be a drug of natural origin possessing anti-ulcer activity.
