The article delves into the academic connotation and clinical thinking of the"Nineteen Pathogenesis Patterns"from the core concepts of Yellow Emperor's Inner Classic(Huang Di Nei Jing).It aims to grasp the complex and diverse manifestations of human symptoms through the image-based thinking;to compare and analyze the obtained"images"with the help of the theories of Yin-yang,Five Elements,and Qi-essence;and to form a complete understanding of the occurrence and development of diseases from a holistic,functional,dynamic and harmonious perspective.This approach focuses on breaking through the limitations of the traditional"disease-syndrome-prescription"framework,making the study of the"Nineteen Pathogenesis Patterns"more in line with the original essence of the Yellow Emperor's Inner Classic and providing a reference for interpreting more traditional Chinese medicine theories and clinical ca-ses.
