【功效】解表散寒,温中止呕,温肺止咳。       
 
【应用】        1.风寒感冒。本品辛散温通,能发汗解表,祛风散寒,但作用较弱,故适用于风寒感冒轻证,可单煎或配红糖、葱白煎服。本品更多是作为辅助之品,与桂枝、羌活等辛温解表药同用,以增强发汗解表之力。

3.胃寒呕吐。本品辛散温通,能温胃散寒,和中降逆,其止呕功良,素有“呕家圣药”之称,随证配伍可治疗多种呕吐。因其本为温胃之品,故对胃寒呕吐最为适合,可配伍高良姜、白豆蔻等温胃止呕药。若痰饮呕吐者,常配伍半夏,即小半夏汤(《金匮要略》);若胃热呕吐者,可配黄连、竹茹、枇杷叶等清胃止呕药。某些止呕药用姜汁制过,能增强止呕作用,如姜半夏、姜竹茹等。
