       【药性】苦,微寒。归肺、胃经。        【功效】清肺止咳,降逆止呕。       
 
【应用】        1.肺热咳嗽,气逆喘急。本品味苦能降,性寒能清,具有清降肺气之功。可单用制膏服用,或与黄芩、桑白皮、栀子等同用,如枇杷清肺饮(《医宗金鉴》);治燥热咳喘,咯痰不爽,口干舌红者,宜与宣燥润肺之品桑叶、麦冬、阿胶等同,如清燥救肺汤(《医门法律》)。      
 
  2.胃热呕吐,哕逆。本品能清胃热,降胃气而止呕吐、呃逆,常配陈皮、竹茹等同用。

【古籍摘要】        1.《名医别录》:“主卒啘不止,下气。”       
 
 2.《本草纲目》:“和胃降气,清热解暑毒;疗脚气。”“枇杷叶,治肺胃之病,大都取其下气之功耳。气下则火降痰顺,而逆者不逆,呕者不呕,渴者不渴,咳者不咳矣。”“治胃病以姜汁涂炙,治肺病以蜜水涂炙。”       
 
3.《重庆堂随笔》:“凡风温、温热、暑、燥诸邪在肺者,皆可用以保柔金而肃治节,香而不燥,凡湿温、疫疠、秽毒之邪在胃者,皆可用以澄浊而廓中州。本草但云其下气治嗽、啘,则伟绩未彰,故发明之。”       
 
【现代研究】        1.化学成分:本品含挥发油(主要为橙花椒醇和金合欢醇)以及酒石酸、熊果酸、齐墩果酸、苦杏仁苷、鞣质,维生素B、C,山梨醇等。       
 
 2.药理作用:本品有镇咳、平喘作用,祛痰作用较差;煎剂在体外对金黄色葡萄球菌有抑制作用,对白色葡萄球菌、肺炎双球菌及痢疾杆菌亦有抑制作用。乙醚冷浸提取物及所含熊果酸有抗炎作用。       
 
3.临床研究:鲜枇杷叶煮后,煎液浓缩,空腹服用,治小儿蛲虫病122例,结果阴转率67.21%,肛周成虫阴转率为78.85%,肛周虫减少率为88.14%。(中医研究,1989,2:32);枇杷叶,配杏仁、栀子、淡豆豉组成枇杷叶煎,配合短程(7日内)的西药对症处理,治疗小儿急性肾炎,在提高治愈率、预后等方面,均优于单一的治疗方法。(河北中医,1998,6:325)。
