摘要: “流气化湿”为清代医家叶天士治疗温病的常用方法，以轻苦微辛、清轻灵动之品开泄三焦气机，使湿化热解。临床可用于温热、湿热类邪气痹阻，导致气机不利的皮肤病，为皮肤科疾病的辨治开拓了思路。本文以“流气化湿”理论为基础，阐述“轻苦微辛”之品的性味特点与配伍规律，结合皮肤科常见疾病如痤疮、湿疹、荨麻疹等，论证该法在皮肤科的应用病机、具体应用及临床价值。

Abstract: “Activating Qi to Resolve Dampness” is a frequently employed therapeutic strategy by Ye Tianshi, a renowned physician of the Qing Dynasty, for treating warm diseases. This method utilizes herbs and ingredients that are mildly bitter, slightly pungent, light, and agile to unblock and regulate the qi mechanism of the Triple Burner (Sanjiao), thereby facilitating the transformation of dampness and the resolution of heat. Clinically, it is applicable to dermatological conditions caused by the obstruction of warm-heat or damp-heat pathogens, which lead to impaired qi dynamics, thus opening up new perspectives for the syndrome differentiation and treatment of skin diseases. Based on the theory of “Activating Qi to Resolve Dampness”, this paper elucidates the flavor and property characteristics as well as the compatibility rules of “mild bitter and slightly pungent” substances. Furthermore, by integrating common dermatological conditions such as acne, eczema, and urticaria, it demonstrates the pathogenesis, specific clinical applications, and therapeutic value of this method in dermatology.
