基于“三消”燥热学说探讨糖尿病中医治疗

Exploration of TCM Treatment for Diabetes Mellitus Based on the “Three Xiao” Dry-Heat Theory

摘要: 糖尿病属中医“消渴”范畴，传统多以“三消”理论(上消、中消、下消)辨证施治，上消在肺，中消在胃，下消在肾。金元时期刘完素提出“三消者，燥热一也”，奠定燥热内生为消渴之核心病机，肺燥多饮，胃热多食，肾虚多尿，三者相因，燥热始终贯穿于疾病始终。从“三消”燥热学说出发，系统梳理该学说的理论源流、核心病机与辨证分型，并在此基础上，深入探讨其在糖尿病中医治疗中的具体应用，包括治则治法、经典方药、药物配伍以及与现代医学认识的结合。结合现代研究进展，总结有效的中药方剂和治疗方法，为临床提供理论支持与实践指导。

Abstract: Diabetes mellitus falls within the scope of “Xiao-ke” (consumptive thirst) in traditional Chinese medicine (TCM), and pattern identification and treatment have long been guided by the “Three Xiao” doctrine—upper-xiao (lung), middle-xiao (stomach) and lower-xiao (kidney). In the Jin-Yuan period Liu Wansu stated, “The three types of xiao are but one: dry-heat,” thereby establishing endogenous dry-heat as the core pathogenesis of “xiao-ke”. Lung dryness produces excessive drinking, stomach heat produces excessive eating, and kidney deficiency produces excessive urination; the three are mutually causal, and dry-heat runs through the entire course of the disease. Starting from the “Three-Xiao” dry-heat theory, this article systematically reviews its theoretical origins, core pathogenesis and pattern sub-types, and on this basis discusses in depth its concrete application in the TCM treatment of diabetes—including therapeutic principles and methods, classical formulas, herbal combinations and integration with modern biomedical knowledge. By synthesising contemporary research, it summarises effective Chinese-medicine formulas and therapeutic approaches, providing theoretical support and practical guidance for the clinic.
