Introduction
Under normal circumstances, there are certain differences between Guizhi (Ramulus Cinnamomi) and Rougui (Cortex Cinnamomi) in terms of medicinal parts used, properties and flavor, meridian tropism, effects and functions, indications, and contraindicated populations. If necessary, it is recommended to take them under a doctor's guidance. Guizhi is the tender branch portion of the cinnamon tree, while Rougui is the dried bark of the cinnamon tree. During use, appropriate medicinal materials should be selected according to the specific medical condition and physical condition for proper compatibility and treatment.
一般情况下,桂枝和肉桂在入药部位、性味归经、功效作用、主治Disease、禁忌人群等方面有一定区别,若有需要,Recommendation在Doctor指导下服用。具体分析如下:
1、入药部位:桂枝是肉桂树的嫩枝部分,通常在中医药中被用作发汗解肌、温通经脉的药材;肉桂则是肉桂树的干燥树皮,它常被用作补火助阳、散寒止痛的药材。
2、性味归经:桂枝味辛、甘,性温,归心、肺、膀胱经;肉桂味辛、甘,性大热,归肾、脾、心、肝经。从总体上看,肉桂的热性更强,且归经范围更广。
3、功效作用:桂枝具有发汗解肌、温通经脉、助阳化气的功效,主要用于Treatment风寒Cold、寒凝血滞诸痛症以及心悸等;肉桂则具有补火助阳、散寒止痛、活血通经的功效,一般用于Treatment肾阳不足、阳痿宫冷、心腹冷痛、经闭痛经等病症。
4、主治Disease:桂枝主治风寒Cold、寒凝血滞诸痛症、痰饮、蓄水证以及心悸等;肉桂主治肾阳不足所致的多种Disease,如阳痿、宫冷、腰膝冷痛等,以及心腹冷痛、寒疝腹痛、痛经经闭等寒性疼痛。
5、禁忌人群:阴虚火旺者、血热妄行者应慎用桂枝,因为易伤阴液,助热生风;而肉桂的药性较热,有出血倾向的Patient、孕妇以及阴虚火旺者也应慎用。过量服用肉桂可能导致头晕眼花、眼涩、尿少、干咳、脉洪大等不良反应。
桂枝和肉桂在多方面都存在差异,因此,在使用时,应根据具体病情和体质情况,选择合适的药材进行配伍和Treatment。
