论《黄帝内经》之“虚邪”

On “deficient pathogen” in Huangdi’s Internal Classic

"邪气"亦称为"虚邪",是《黄帝内经》病因学核心范畴。邪气亦称虚邪,两者在《黄帝内经》中有明确的性质指向、发生背景、致病时机等认识。邪者斜,是指自然气候中非时令之气,具有致病性;虚邪的概念源自运气理论,是指中运不及、本位气虚引动其他时令的气候来至,又称为胜复之气。对邪气、虚邪进行深入解读,对正确阐释《黄帝内经》的病因学理论,以及充分发挥其在防病治病中的作用具有重要意义。

The pathogen, also known as "deficient pathogen", falls into the core category of etiology in Huangdi Neijing(Huangdi’s Internal Classic), where there are specific statements of its properties, occurrence, and the timing of disease onset. The pathogen refers to non-seasonal pathogenic qi of natural climate. The concept of deficient pathogen originates from the doctrine of five evolutive phases and six climatic factors. The deficient pathogen, also termed as the alternating qi, refers to the climate deriving from other seasons triggered by qi deficiency due to failure of transportation in the middle jiao. An in-depth analysis of the pathogen and the deficient pathogen is of great significance for interpreting the etiological theory of Huangdi Neijing and giving full play to its role in prevention and treatment of diseases.
