Sanjiao identification is a method of identification that incorporates the various certificates of exogenous warm-heat disease into the epiglottis, middle-heat disease, and lower-heat disease respectively, and elucidates the pathological changes of the organs belonging to the sanjiao in the course of the warm-heat disease, the clinical manifestations, the characteristics of the certificates, and their patterns of transmutation. 1. The upper jiao evidence mainly includes the lesions of the hand taiyin lung and the hand syncope yin pericardium, while the hand taiyin lung meridian evidence is mostly for the initial stage of the warm disease, and the condition is light; the hand syncope yin pericardium meridian evidence is for the lung meridian warmth and heat of the evil spirit trapped in the pericardium of the evidence. 2. The middle jiao evidence mainly includes the foot yangming stomach, foot taiyin spleen and hand yangming large intestine, and the foot yangming stomach is mainly dry, easy to dry from the dry, mostly for the internal heat dry solid evidence; foot taiyin spleen is mainly wet, easy to wet from the wet, mostly for the wet and warm (feel the wet and heat caused by the wen disease) disease evidence. Middle Jiao diseases are mostly in the middle stage of warm diseases, and the condition is more serious. 3. Lower Jiao symptoms mainly include lesions of the foot-shao-yin kidney and the foot-convulsive Yin liver, which belong to the end stage of warm disease, and are mostly manifested as liver and kidney yin deficiency (deficiency of yin in the liver and kidneys), which is a serious condition. If you need to carry out San Jiao diagnosis, you need to find a professional Chinese medicine doctor to do so.
