通下法在温热病证中的应用

Application of Purgation Method in Febrile Syndromes

中医通下法理论?于《内经》,奠基于《伤寒论》。温病学延续了《伤寒论》下法,并对其有进一步的发展和完善。温病学家不但创立了多首加减承气汤,以适应温热病证易于化燥伤阴的病机特点,而且在下法应用理论上提出了"邪为本,热为标,结粪又其标也",下法"非专为结粪而设","勿拘下不厌迟","邪未尽可频下"等观点,为攻下法的推广应用奠定了理论基础。其目的在于逐邪热,下燥粪,保津液,祛瘀结,具有"祛邪存正"的意义。由于通下法作用强烈,收效迅速,如运用得当常可收到扭转病势之效果,但具体应用时又应严格掌握其临床指征和注意事项。

Purgation method in TCM comes from Internal Classic, and founded on Treatise on Febrile Diseases. Science of Epidemic Febrile Diseases succeeded to the method of purgation, and developed and improved it further. The scholars of Febrile Diseases not only set up lots of modified Purgative Decoctions, but also put forward many points of view, such as ＇Evil-based in origin, and heat as superficiality, hard fecal is also in suPerficiality＇ od ＇ Purgation method is not only designed for hard fecal＇ , ＇ Never mind being late for using purgation methand ＇ purgation method can be used many times even if evil has not gone thoroughly＇. They laid a theoretical foundation for the application of purgation method. The aim was to expel evil heat, unload dry dung, protect body fluid, and remove blood stasis, and the meaning was to eliminate pathogen and strengthen body resistance. Because of its strong and rapid efficacy, proper application often has the effect of reversing an illnes. But the specific application should strictly control the clinical indications and medication taboo.
