| Objective Carry out basic research on the theory of nature and flavours of Huangdi Neijing(hereinafter referred to as Neijing),analyze the clinical significance of the theory of nature and flavours of Neijing,especially its guiding role in formulating classical prescriptions,and finally discuss its influence on later generations.It is hoped to provide reference for our modern clinical application.Methods Systematically sort out and summarize the content related to nature and flavours of the Neijing,starting with the meaning of the nature and flavours,the connotation of the four nature,the treatment method and the principles of use,the connotation,efficacy and use taboos of the five flavours,and the law of compatibility of four nature and five flavours.,and prepare the material basis for the theory of nature and flavours of Neijing.By discussing the clinical significance of the nature and flavours of Neijing,it leads to its guiding role in the compatibility of the classical prescriptions of Zhang Zhongjing.Introduce the six-meridian syndrome differentiation theoretical system proposed by Zhang Zhongjing,explore the the theory of nature and flavours of Neijing of principal prescriptions of the six meridian diseases and its addition and subtraction prescriptions.Results 1.The nature and flavours mostly refers to the natural properties of medicines and foods that can have an effect on human physiology and pathology.The nature and flavours is divided into yin and yang,according to the thickness of it,and can be divided into yin and yang.The four nature refer to the four attributes of "cold,hot,warm,and cool",and the ping qi can also be included.Five flavours are mainly used to reflect the efficacy of medicines and foods.The use of four nature embodies positive treatment,anti-treatment and anti-adjudication methods of Chinese medicine,and the application should comply with the principle of adapting measures to time and disease.The effects of the five flavours are mainly based on the theory of five zang viscera like or dislike and the theory of inter-restriction of Five elements.Reasonable use of the five flavours can nourish the five zang,but avoid overeating,otherwise it will lead to diseases.2.The theory of nature and flavours of Neijing has extremely high clinical value,The efficacy of it can indicate the main function of drugs;the contraindication can indicate the direction of medication,the compatibility can enhance the properties of drugs,expand the treatment range of prescriptions,and reduce their toxic and side effects.3.Analyzing the principal prescriptions and its addition and subtraction prescriptions of the six meridian diseases,we can see that the compatibility of Zhang Zhongjing’s prescriptions is not a simple linear addition of the four nature and five flavours and efficacy of the drug,but under the guidance of the theory of nature and flavours of Neijing,the four nature and five flavours and efficacy of the drug are combined according to the structure of the monarch-minister-assistant-envoy,the relationship of seven Qing and the theory of ascending and descending 4.Later generations of physicians inherited and developed the theory of nature and flavours of Neijing.Zhang Zhongjing used his experience in formulating prescriptions to provide reference for them to formulate and explain prescriptions.Conclusion The content of the theory of nature and flavours of Neijing is extremely rich,and it has an important guiding role in the compatibility of classical prescriptions.The theory of nature and flavours of Neijing and its application in the compatibility of classical prescriptions have profoundly affected the clinical practice of later generations of physicians,and the clinical practice of later generations of physicians in turn promoted the development and perfection of the theory of nature and flavours,forming The virtuous circle of the development of Chinese medicine. |
