This study was undertaken to investigate effects of Oyo-Tang on the respiratory system. The results of this study were summerized as follows; 1. Antihistamine and relaxed dialating actions were recognized on the extracted ileum and serial broncheal samples in guinea-pigs. 2. Mild hypertensive action was recognized on the carotid artery in rabbits. 3. Antitussive action was noted on mechanically irritated coughs in dogs and cats. In connection with the results of these studies, effects based on the Oriental medical references were consistant with the actual experimental results. It was considered that effective application of Oyo-Tang for the treatment of cough and asthma could be justified.
