Hyangsayangwee-Tang, a combined preparation of crude drugs, which has been used for stomach and intestinal disorder, was examined for anti-spasmodic, anti-ulcerative and anti-emetive effects. Spontaneous motility of isolated ileum was strongly suppressed and inhibitory effects against contraction of isolated ileum induced by acetylcholine and barium chloride were shown in mice. And, contraction of isolated guinea-pig ileum by histamine was inhibited. In rats fundus preparations, Hyangsayangwee-Tang elicited strong relaxation and had antagonist effects against the spasm induced by acetylcholine and barium chloride. A significant inhibitory effect on the intestinal propulsion of barium sulfate in mice was shown. In pylorus-ligated rats, Hyangsangwee-Tang inhibited gastric secretion and showed a strong anti-peptic activity. Protective effects against gastric ulceration induced by pyloric ligation, water-immersion stress, histamine and aspirin were significantly recognized in mice and rats. Hyangsayangwee-Tang decreased cupric sulfate-induced vomitting in frogs.
