Experiments indicated that the ethanol extract and ether extract from Rhizoma Cynanchi Stauntonii showed obvious antitussive and expectorant effects in mice with stomach administration. The antitussive effect of ethanol extract was stronger than the expectorant effect. The water extract showed a certain expectorant effect but no marked antitussive effect with oral administration. Obvious anti-inflammatory effect was observed on croton oil-caused mouse ear swell with intraperitoneal injection.
实验表明，白薇乙醇提取物和乙醚提取物经胃给药对小鼠有明显的镇咳和祛痰作用。乙醇提取物的镇咳作用强于祛痰作用。水提取物经口服有一定的祛痰作用，但无明显镇咳作用。腹腔注射时，对巴豆油所致小鼠耳肿胀有明显抗炎作用。
