1、第七章 辨证 Chapter 7 differentiation of syndrome Syndrome is the pathological summarization of a disease in a certain stage. It includes the location, cause, nature, and relationship between healthy qi and pathogenic factors. It reflects the essence of pathological changes in the process of the disease

2、at some stage, so it is more comprehensive, more profound and more correctly reveal the nature of the disease than the manifestations. 证（证候）证（证候）: : 是机体在疾病发展过程中的某一阶段是机体在疾病发展过程中的某一阶段 的病理概括。的病理概括。 它包括病变的部位、原因、性质及邪它包括病变的部位、原因、性质及邪 正关系，反映出疾病发展过程中某一阶正关系，反映出疾病发展过程中某一阶 段的病理变化的本质，因此它比症状更段的病理变化的本质，因此它比症状更 全面

3、、更深刻、更正确地揭示了疾病的全面、更深刻、更正确地揭示了疾病的 本质。本质。 The difference between Manifestation and Syndrome Manifestations reflect the outward sign of disease, Syndrome reflects the nature of the disease 症和证的区别：症和证的区别： 症状是疾病的外在表现，证是疾病的症状是疾病的外在表现，证是疾病的 本质反映。本质反映。 Differentiation of syndrome ： means to analyzing and ju

Syndrome differentiation with eight principles 八纲辨证：八纲辨证： 通过四诊通过四诊，掌握辨证的资料之后掌握辨证的资料之后，根据根据 病位的深浅病位的深浅，病邪的性质及盛衰病邪的性质及盛衰，人体正人体正 气的强弱等气的强弱等，加以综合分析加以综合分析，归纳为归纳为阴阴、 阳阳、表表、里里、寒寒、热热、虚虚、实实八类证候八类证候。 八纲：八纲：阴阴、阳阳、表表、里里、寒寒、热热、虚虚、实实 八个纲领八个纲领 “表里表里”是辨别是辨别病证的内外深浅位臵病证的内外深浅位臵的纲领。的纲领。 External or int

11、d pathogenic factors. 八纲之间的相互联系：八纲之间的相互联系： Interlinkages between the eight principles “阴阳阴阳”两纲可概括其他六纲：两纲可概括其他六纲： 表表、热热、实证属实证属“阳阳”， 里里、虚虚、寒证属寒证属“阴阴”， 所以所以“阴阳阴阳”又是八纲中的总纲又是八纲中的总纲。 Yin and yang can be used to general other six principles: external, heat and sthenia are of yang; while internal, cold and

12、asthenia are of yin. So yin and yang are the general principles in all the eight principles. 一、表里一、表里 Exernal and internal 表里是相对的概念表里是相对的概念 Exernal and internal are two relative concepts 即病证的内外深浅位臵都是相对而言的即病证的内外深浅位臵都是相对而言的。 The depth and inside or outside of the disease location are relative. . 表里病位的
