"亢害承制"是五运六气中的一个重要理论,自然界五运六气能够循环不息、生化有度全是依赖五运六气之间的制化作用。"亢害承制"理论中蕴涵着五行胜复、生克制化的道理。无论是自然规律还是人体内环境,甚或说"天地万物"都是在五行生化的规律下有序地进行着,而"亢则害,承乃制"中"亢"是指过极,过极则会损害自然的动态平衡,即为"亢则害"。五行是相生相克的,于人体也是如此。然克我者并不只是贼邪,此所谓无克亦无生,制则生化是自然之道。熟稔"亢害承制"理论,不仅有利于更好地了解自然气象变化,理解中医基本理论,并且能更好地辨证和治疗疾病。
The Theory,restraining excessiveness to acquire harmony,is a very important theory from the theory of five movements and six Qi. The circulation,production and diversification of five movements and six Qi natural relied on the restricted relationship of them. This theory contained truth the resistance of oppressed elements and interrelationship between generation and restriction.No matter natural law or physical circumstances. All things are operated orderly in the five elements. Excessiveness means extreme which will damage the dynamic balance of nature. In other words,extreme is harmful. The five elements are inter-promoting and inter-restriction relation to each other,so is human body. However,the matter which is restricted to me is not only exogenous pathogens. It means no inter-resurrection,no inter-promoting. Resurrection gives birth to promoting,which is the natural Dao. Knowing intimately this theory is beneficial to know the natural climate change and the basic theory of TCM,which is better treat disease by syndrome differentiation.
