Interpretation of the Medical System in Classic of Difficulties
According to Classic of Difficulties,grains and other foods are the fundamental sources of nourishment for human life activi-ties.The six fu organs are responsible for receiving and digesting these grains,transforming them into refined substances,while the five zang organs store these refined substances to house the spirit.The transportation of these refined substances between their generation and storage is carried out by the triple energizer.The development and transmission of diseases follow the principle of"seven transmis-sions."The first stage involves the external invasion of the six pathogenic factors,which Classic of Difficulties refers to as"cold dam-age".The second stage involves the invasion of the five zang organs by pathogenic qi.If untreated,the disease progresses following the control cycle:from the heart to the lungs(which is the third stage),the lung to the liver(the fourth stage),the liver to the spleen(the fifth stage),the spleen to the kidney(the sixth stage),and finally,from the kidney back to the heart(the seventh stage).If the trans-mission is interrupted by"the ruling organ not receiving evil"condition,accumulations or masses may form.Classic of Difficulties em-ploys a diagnostic system integrating"disease,pulse,and diagnosis".It cross-references pulse diagnosis with both internal and external manifestations of disease.Physicians diagnose the corresponding pulse of the five zang organs and confirm the diagnosis through inquiry,inspection,and listening.If the internal and external symptoms match the expected organ pulse,the pulse diagnosis is considered accu-rate;otherwise,re-diagnosis is required.When pathogenic qi first invades the body,Classic of Difficulties advocates treatments using sweating and purging methods.If there is deficiency or damage to the internal organs,the dispelling of the pathogenic qi is supplemented with tonification to prevent the external pathogens from penetrating deeper into the body.Acupuncture often follows the defense qi acu-puncture method,where pulse diagnosis is used to determine the area of the body affected by pathogenic qi.Based on the principle of"the division of defense qi and the circulation of nutrient qi along the meridians,"specific acupuncture points are selected accordingly for treatment.Classic of Difficultie regards the"Mingmen(GV4)between the kidneys"as the primary source of vital energy in the hu-man body,with the triple energizer acting as the pathway for its circulation.Guided by the theories of yin-yang and the five elements,it establishes a unique medical system centered around the"Mingmen(GV 4)-the triple energizer-five elements"framework for diagnosis and treatment.
