The following results have been obtained; 1. Wahngkigunchunghapleechungtang showed to have an inhibitory effects on the smooth muscle contraction of the isolated ileum by acetylcholine chloride and barium chloride. 2. Wahngkigunchunghapleechungtang showed to have an inhibitory effect on the contraction of the gastric fundus-strip by acetylcholine chloride and barium chloride. 3. The preventive effects were not recognized on the pylorus-ligated ulcer, by administration of Wahngkigunchunghapleechungtang. 4. The preventive effects were recognized on the indomethacin-induced ulcer by administration of Wahngkigunchunghapleechungtang. 5. The Inhibitory effects on the secretion gastric juice, free & total acidity, and pepsin output were recognized by administration of Wahngkigunchunghapleechungtang. 6. The transport abilities in the small intestine were not recognized by administration of Wahngkigunchunghapleechungtang. 7. The transport abilities in the large intestine were increased by administration of Wahngkigunchunghapleechungtang. According to the above results, it is considered that the experimental effects of Wahngkigunchunghapleechungtang has correspond to the oriental medical literatures.
