【Abstract】 Objective:To evaluate the cough-settling, phlegm-dispelling and panting-calming actions of Ginkgo Distillate. Methods: The cough-settling and phlegm-dispelling effects were observed on the ammonia water-induced cough model of mice and phenol red expectoration method. The panting-calming effect was observed by wheezing and panting incubation period and relaxation test of isolated tracheal smooth muscle. Results: Ginkgo Distillate could inhibit mouse cough induced by ammonia water, promote mouse tracheal expectoration induced by phenol red, remit the wheezing and panting induced by histamine phosphate, prolong the wheezing and panting incubation period. It also possessed the inhibition on guinea pig tracheal contraction induced by histamine phosphate. Conclusions: Ginkgo Distillate has the cough-settling, phlegm-dispelling and panting-calming actions.更多还原
