Results GJDCC could resist the convulsion of the isolated trachea of guinea pigs, lengthen the asthma incubation period of guinea pigs, increase the phlegm liquid secreting capacity of isolated rat trachea, promote the pigeon trachea cilium motion, lengthen the mice cough incubation period, restrain the mice ear swelling and rat swelling hyperplasia of granulation, promote the mice producing of serum hemolysin and the lymphocyte conversion rate, and reduce the guinea pig allergic reaction index and shock death rate. It possessed the bacteriostasis, the biggest capacity of bearing consumption was 500 times the clinical daily use and in long-term toxicity test there were not the clear toxicity reactions. Conclusion GJDCC has the function of relieving asthma and cough, removing phlegm, antibiosis and antiinflammation, antianaphylaxis and immunity, without poisonous side effect.
