本文通过对肝“体阴用阳”理论内涵进行剖析，分别阐释了肝的“体阴”与“用阳”生理病理机制，描述了其相应证候机制与症状特点，分析了调肝经典方药的组方规律，通过临床验案证实肝“体阴用阳”的临床指导意义。认为肝的升发之性，是升发人体之气以适应天地之气升发的必要保障，是维持人体气机升降平衡的关键。肝气升发失常主要体现为升发太过与升发不及两大类型，具体分析了肝气升发失常病机特点与临床表现；提出肝藏血实为肝之收敛与涵养特性新观点，阐释了肝藏血主疏泄之间的收敛贮藏与升发条达的关系，认为肝藏血涵养收敛肝气使其不过亢，肝藏血可养魂安神，肝藏血为经血生成之源等观点。本文最终提出“平肝降逆必兼养阴柔肝，疏肝解郁亦应养肝养血，清肝泻火不忘凉血养阴”的临床调肝组方观点，具有一定临床指导价值。

This paper was aimed to analyze the theoretical connotation with liver “body yin with function yang”, and to explain the physiological and pathological mechanism of “body yin” and “function yang”, respectively. The mechanism of its corresponding syndrome and symptoms were described and the composing principle of classical prescription for liver regulation was analyzed. The clinical significance of liver “body yin with function yang” was confirmed by clinical cases. This paper argued that the liver ascending characteristics, which is a necessary guarantee for ascending qi in the human body to adapt to the ascending gas of the world, is the key point to maintain balance of qi ascending and descending in the body. The liver ascending disorder mainly manifested for the excessive ascending and ascending deficiency, which analyzed the pathogenesis characteristic and clinical manifestation of the liver qi ascending disorder. This paper put forward a new view that the liver storing blood referred to the convergence and the conservation properties of the liver, which demonstrated the relationship between liver storing blood and controlling dispersion. It suggested that liver blood convergences liver qi so as not to make liver qi too excessive. The liver storing blood can raise spirit. Liver blood is the source of menstruation, and etc. This paper finally put forward the clinical prescription viewpoint of “soothing liver and dropping inverse should raise yin and gentle liver necessarily”, “releasing liver should raise liver and nourish blood” and “clearing away the liver-fire should cool blood and nourish yin”. This research had certain clinical value.
