Objective:To investigate the main pharmacological effects of a Chinese traditional compound

Chuanbei Xueli Extract.Methods:The following experiments were carried out:cough induced by ammonia and sulfur dioxide

in vivo and in vitro tests for relieving asthma

phlegm removing with phenol red and capillary

fever caused by dried yeast and triple vaccine

and the inflammation model caused by dimethylbenzene and carrageenin.The effects of the drug on inhibiting cough

relieving asthma

removing phlegm

reducing fever

and antagonizing inflammation were investigated.Results:Chuanbei Xueli Extract significantly prolonged the latent period of cough in mice

increased the latent period of induced asthma in guinea pigs

relaxed the isolated tracheal smooth muscle of guinea pigs

increased the elimination of phenol red in mice

increased the elimination of phlegm volume in rats

lowered the high temperature of rabbits caused by triple vaccine

and inhibited the imflammatorys welling caused by dimethylbenzene and carrageenin.Conclusions:Chuanbei Xueli Extract has significant effects on inhibiting cough

relieving asthma

removing phlegm

reducing fever

and antagonizing inflammation.
