气候变化对中医药寒热相关理论形成的影响

古代医生对外界病因的认识既具直观性特点，又具辩证性特点。中医发展史中气候冷暖的变化形成了直观认识的寒温病因差异，直观认识和辩证思维以及药物治疗的良好效果共同构成了自然气候冷暖影响下的寒温相关理论。寒冷期寒邪伤人的外因、患病机体的寒性表现和阳气受损的病理生理特点以及对治疗药物温热属性的界定产生了伤寒学说；温暖期温邪伤人的外因、患病机体的热性表现和阴津亏损的病理生理特点以及对治疗药物寒凉属性的界定产生了温病学说。直观认识和辩证思维不相一致时，就形成了伤寒学说中的“传经”理论和温病学说中的“温化”认识。

Effect of Climate Changes on the Formation of Cold and Heat Related TCM Theories

The ancient doctors＇ viewpoints on exopathogenic factors are both intuitive and dialectical. The climate changes caused an intuitive understanding of the cold and heat etiological differences during the development TCM. The intuitive understanding and dialectical thinking and the good effects of drug treatment constituted the cold and heat related theories under the influence of natural climate. The external causes of cold pathogen in the cold period, sick body＇ s cold performance and the pathophysiological characteristics of yang damage and the determination of warm and heat properties of drugs produced the theory of cold-damaged disease. The external causes of warm pathogen in the warm period, sick body＇ s warm performance and the pathophysiological characteristics of yin fluid exhaustion and the determination of cool and cold properties Of drugs formed the warm disease theory. The inconsistency of intuitive understanding and dialectical thinking produced the theory of disease transformation in the theory of cold damage disease and the understanding of warming and transformation in the theory of epidemic febrile disease;
