试论“血之源头在乎肾”

Discussion on "Origin of Blood Is Kidney"

血在脉道中运行,流注周身,循环不已,维持人体正常的生理活动。肾为先天之本,肾主藏精,肾阴肾阳为五脏阴阳之本,其在血生成的过程中起着非常重要的作用,肾也影响着血行,故有"血之源头在乎肾"之说。肾精、肾气、肾阴、肾阳在血化生的过程中起着关键的作用,肾是血化生的本原和动力,血液运行同样与肾关系密切,肾虚可导致血虚,亦可引起瘀血、出血等病理改变。在治疗上,当遵"损其肾者益其精""形不足者,温之以气;精不足者,补之以味"的原则,具体方法有填肾精益精髓而资血、温肾阳益肾气而养血、平补肾阴肾阳而生血等。
