姜半夏的功效与作用及禁忌

姜半夏和其他半夏的区别

药材经过不同的炮制方法,添加不同的成分,在原先药材的基础上创造出了一种既继承又发展的一种药材,姜半夏就是半夏经过生姜和白矾的精确配比炮制而成的一种药材,那么他究竟在什么方面实现了对半夏的继承和发展呢?

姜半夏的功效与作用

1、用于痰多咳嗽。

半夏性燥而功能化痰,其所化之痰,以脾不化湿,聚而成痰者为主,为治湿痰的要药,适用于痰湿壅滞、咳嗽气逆等症,常与陈皮、茯苓等配伍。治痰多咳嗽,又常与贝母配伍应用。因其性温,故又可用治寒痰,宜与白芥子、生姜等同用。因其化痰力佳,故亦可治热痰与风痰,治热痰可与瓜蒌、黄芩等配伍。致风痰,宜与天南星等同用。

2、用于胸脘痞闷,胸痹,结胸等症。

半夏功能辛散温通、化痰、燥湿,故可用于痰内阻、胸脘痞闷病症,可配陈皮、茯苓等同用。如寒热互结,有可配黄芩、黄连、干姜等同用,可收辛开苦降、散结除痞的功效(如半夏泻心汤)。此外,又常用于胸痹疼痛,配瓜蒌、薤白等同用。治结胸症可与瓜蒌、黄连等同用。

3、用于瘿瘤瘰历、疮疡肿痛、梅核气等症。

半夏又能化痰散结,可用以治疗痰湿结聚所致的瘿瘤、瘰历痰核、阴疽肿痛,或痰气互结的梅核气等病症。用治瘿瘤瘰历痰核,可与海藻、黄独、贝母等配用。痈疽未溃者可用生半夏配生南星等同研,调醋外敷,有散结消肿的功效。用治梅核气,可配厚朴、紫苏等同用。

姜半夏的食用禁忌

不宜与川乌、制川乌、草乌、制草乌、附子同用。

姜半夏和其他半夏的区别

1、生半夏:直接采收的本品呈类球形,有的稍扁斜,直径1~1.5厘米,表面白色或浅黄色。顶端有凹陷的茎痕,周围密布麻点状根痕,习称“棕眼”。下面钝圆,较光滑。质坚实,断面洁白,富粉性。气味辛辣,麻舌而刺喉。其饮片呈钝圆形薄片,有的边缘呈凹陷状(茎痕的剖切面)。

2、清半夏:半夏与白矾以1∶0.2比例炮制而成,为椭圆形、类圆形或不规则片状,椭圆形、类圆形的饮片上有的具凹陷的茎痕。切面淡灰色至灰白色,可见灰白色点状或短线状维管束迹,有的残留栓皮处显淡紫色斑纹。质脆,易折断,断面略呈角质样。气味微涩,微有麻舌感。

3、姜半夏:半夏与生姜、白矾为以10∶2.5∶1.25比例炮制而成,为片状、不规则颗粒状或类圆形。表面棕色至棕褐色,质硬脆,切面淡黄棕色,常具角质样光泽。气微香,味淡,微有麻舌感,嚼之略黏牙。

4、法半夏:半夏与甘草煎煮、加入石灰液中浸泡后阴干或烘干即得,呈类球形或破碎成不规则状,表面呈淡黄白色、黄色或棕黄色,质较松脆或硬脆。断面呈黄色或淡黄色颗粒状。气味淡略甘,微有麻舌感。

半夏的产地分布

半夏主要分布于湖北、河南、安徽、山东、四川、甘肃;浙江、湖南、湖北、江苏、河北、江西、陕西、山西、福建、广西、贵州、云南亦有分布。

半夏主产于湖北武昌、老河口、襄阳、阳新、天门;河南汝南、灵宝、卢氏、渑池、息县、淮滨、唐河;安徽怀宁、宣城、宁国、阜南、颍上;山东金乡、巨野、胶南、五莲、莱阳;四川遂宁、安岳、万县、昭觉、岳池、壁山、隆昌、荣昌、忠县、营山。

半夏经由不同的炮制方法可以制作出不同的很多半夏,姜半夏只是其中的一种,还有清半夏,法半夏等等的一些,并且每一种经过炮制的半夏会在功效上面有所差别,而关于这些,致富热都能给您最好的解答。
