本文简要回顾了中医认识病因的方法，并以“六淫”中的风为例，系统分析中医病因的隐喻特征，认为风之所以成为致病因素、有如此致病特征，是古代中医学家将人们对自然界风的认识移植到中医理论之中，从认知语言学的角度看是一种“隐喻认知”，是以我们熟悉的事物说明我们不熟悉事物的一种方式，作为病因概念的六淫是一种概念隐喻。

Methods used in the etiology of traditional Chinese medicine (TCM) were briefly reviewed. This article provided the metaphorical characteristics of TCM in the analysis of etiology systematically. Wind, one of the Six Evils, was used as an example. It concluded that ancient TCM physicians had transplanted some properties of the natural wind into the explanation of TCM theories. Therefore, the concept of Wind as a pathogenic factor and its related characteristics has been used in the medical field. This is the way of metaphorical cognition from the perspective of cognitive linguistics, which interprets unfamiliar things with the help of familiar things. The term of Six Evils in TCM is a metaphorical concept in the explanation of TCM etiology.
