槐花为豆科植物槐Sophora japonica L.的干燥花蕾及花。全国各地区产,以黄土高原和华北平原为多。夏季花未开放时采收其花蕾,称为“槐米”;花开放时采收,称为“槐花”。采收后除去花序的枝、梗及杂质,及时干燥,生用、炒用或炒炭用。

 【药性】苦,微寒。归肝、大肠经。        【功效】凉血止血,清肝泻火。       
 
【应用】        1.血热出血证。本品性属寒凉,功能凉血止血,可用治血热妄行所致的各种出血之证。因其苦降下行,善清泄大肠之火热而止血,故对下部血热所致的痔血、便血等最为适宜。用治新久痔血,常配伍黄连、地榆等,如榆槐脏连丸(《成方便读》);用治便血属血热甚者,常与山栀配伍,如槐花散(《经验良方》)。       
 
 2.目赤、头痛。本品味苦性寒,长于清泻肝火,凡肝火上炎所导致的目赤、头胀头痛及眩晕等证,可用单味煎汤代茶饮,或配伍夏枯草、菊花等同用。       
 
 【用法用量】煎服,10~15g。外用适量。止血多炒炭用,清热泻火宜生用。        【使用注意】脾胃虚寒及阴虚发热而无实火者慎用。       
 
【鉴别用药】地榆、槐花均能凉血止血,用治血热妄行之出血诸证,因其性下行,故以治下部出血证为宜。然地榆凉血之中兼能收涩,凡下部之血热出血,诸如便血、痔血、崩漏、血痢等皆宜;槐花无收涩之性,其止血功在大肠,故以治便血、痔血为佳。       
 
 【古籍摘要】        1.《日华子本草》:“治五痔,心痛,眼赤,杀腹脏虫及热,治皮肤风,及肠风泻血,赤白痢。”       
 
 2.《本草纲目》:“炒香频嚼,治失音及喉痹,又疗吐血衄血,崩中漏下。”       
 
 3.《药品化义》:“槐花味苦,苦能直下,且味厚而沉,主清肠红下血,痔疮肿痛,脏毒淋沥,此凉血之功能独在大肠也,大肠与肺为表里,能疏皮肤风热,是泄肺金之气也。”       
 
【现代研究】        1.化学成分:本品富含芸香苷(Rytub)、槲皮素(Quercetin)、鞣质等。       
 
 2.药理作用:槐花水浸剂能够明显缩短出血和凝血时间,制炭后促进凝血作用更强;其煎液有减少心肌耗氧量,保护心功能的作用。另对堇色毛癣菌、许兰黄癣菌、奥杜盎小芽孢癣菌、羊毛状小芽孢癣菌、星状奴卡菌等皮肤真菌有不同程度的抑制作用。       
 
 3.临床研究:用槐米30g,蚤休、生甘草各15g,烘干研末,分早晚2次,以水、酒送服;配合局部热敷。治疗急性乳腺炎32例,均获愈。治疗时间最短2天,最长7天;一般服药2日肿痛消失,
 
4日而愈(陕西中医,1985,4:74)。取槐花炒黄研成细粉,每次3g,每日2次,饭后用温开水送服。治疗银屑病53例,痊愈6例,显著进步22例,进步19例,无效6例(皮肤病防治研究通讯,1972,3:207)。另有报道,用本品为主,还可用治颈淋巴结核、高脂血症、高血压病及毛细血管出血性疾患等。       
 
 附药 槐角        为槐的成熟果实,原名槐实。性味、功效、主治与槐花相似,但止血作用较槐花为弱,而清降泄热之力较强,兼能润肠,主要用于痔血、便血,尤多用于痔疮肿痛出血之证,常与地榆、黄芩、当归等同用,如槐角丸(《和剂局方》)。煎服,6~12g,或入丸、散。孕妇慎用。
