丹溪补血制火化痰论析疑

Doubts Analysis on Danxi's Theory of Enriching Blood to Restrict Fire and Resolve Phlegm

对于六味地黄丸治疗阴虚久咳的机理,古代医家常以"丹溪曰:久病阴火上升,津液生痰不生血,宜补血以制相火,其痰自除"以释之。然而该文在来源、病机、治法等方面存在诸多疑点,对其进行探讨分析后发现,据现有文献,该论并非出自丹溪原著,论中之"血"当作"阴"之意。

In regard to the mechanism of Liuwei Dihuang Pill to treat chronic cough due to yin deficiency,the ancient TCM practitioners explained it that ＂As Danxi said,chronic disease may result in the flare-up of yin-fire so as to induce the body fluid to produce phlegm rather than blood.In this case,enriching the blood can restrict ministerial fire and the phlegm will be resolved by itself＂.However,many doubts about the source,pathogenesis and treatment exist in this saying.With respective discussion and analysis,the author found that according to limited literatures this saying is not from the original classic of Danxi and the ＂blood＂ in the saying should be regarded as ＂yin＂.
