[Objective]To study the antitussive and expectorant effects of aqueous extract of cudweed. [Method] The mice cough model induced by ammonia, guinea pig cough model induced by acitric acid and method of stimulating mouse＇ trachea with phenol red were used in this experiment. [Results]The aqueous extract of cudweed significantly prolonged the tussive delitescenee of mice, decreased the tussive times of guinea pigs and increased the secretion of mouse＇ trachea induced by phenol red. [Conclusion]The antitussive and expectorant effect of cudweed was obvious.
