Exploration of the layout and gasification characteristics of San Huan traditional Chinese medicine tongue manifestations based on'open-close pivot'theory
Since the Yellow Emperor's Internal Classic,doctors in the past dynasties have continuously enriched and improved the study of tongue zang-fu organs and meridians,and formed the basic theory of tongue zang-fu organs distribution:Tongue root,classified as kidney and vital gate;the left side of the tongue belongs to the stomach,and the right belongs to the spleen;the middle of the tongue goes forward to the lung,and the tip of the tongue goes to the heart;the left side belongs to the liver,the right side belongs to the gallbladder;based on the theory of triple energizer,the upper part of the tongue is the upper energizer,the middle part of the tongue is the middle energizer,and the root of the tongue is the lower energizer.However,there is little research on how the three yin and three yang are arranged in the tongue image.Based on the theory of opening,closing and pivot of Yellow Emperor s Internal Classic,combined with the research results of doctors in past dynasties,this paper deduced the tongue image layout of Shaoyin Shaoyang,Jueyin Yangming and Taiyang Taiyin by analogy method,and named it as the three-ring tongue image,and analyzed the layout,connotation and gasification characteristics of the three yin and three yang in the tongue image,with the evidence of clinical medical cases,which enriched the research content of tongue image layout and gasification.
