       【药性】甘,平。归脾、肺、肾经。        【功效】补气养阴,健脾,润肺,益肾。       
 
【应用】        1.阴虚肺燥,干咳少痰及肺肾阴虚的劳咳久咳。本品甘平,能养肺阴,益肺气。治疗肺金气阴两伤之干咳少痰,多与沙参、川贝母等药同用。因本品不仅能补益肺肾之阴,而且能补益脾气脾阴,有补土生金、补后天以养先天之效。亦宜用于肺肾阴虚之劳嗽久咳。因作用缓和,可单用熬膏久服。亦可与熟地、百部等滋养肺肾、化痰止咳之品同用。       
 
 2.脾虚阴伤证。本品能补益脾气,又养脾阴。主治脾脏气阴两虚之面色萎黄、困倦乏力、口干食少、大便干燥。本品能气阴双补,单用或与补气健脾药同用。       
 
3.肾精亏虚。本品能补益肾精,对延缓衰老,改善头晕、腰膝酸软、须发早白等早衰症状。有一定疗效。如黄精膏方(《千金方》)单用本品熬膏服。亦可与枸杞、何首乌等补益肾精之品同用。       
【用法用量】煎服,9~15g。       
 
【鉴别用药】黄精与山药,均为性味甘平,主归肺、脾、肾三脏,气阴双补之品。然黄精滋肾之力强于山药,而山药长于健脾,并兼有涩性,较宜于脾胃气阴两伤,食少便溏及带下等证。       
 
【古籍摘要】        1.《日华子本草》:“补五劳七伤,助筋骨,生肌,耐寒暑,益脾胃,润心肺”。       
 
 2.《本草纲目》:“补诸虚……填精髓”。       
 
【现代研究】        1.化学成分:本品含黄精多糖、低聚糖、粘液质、淀粉及多种氨基酸(囊丝黄精还含多种蒽醌类化合物)等成分。
