In Chinese medicine, when treating a disease, the doctors take everything into into consideration, including climatic changes, environmental variations, emotional changes, the diet, the urine and the stool, the sleep, and the disorder of sex life. That is the feature of the Three Pathogens Theory in TCM. This etiology doctrine built on the basis of the macro methodology entirely differs from that of Western medicine. It is on the basis of the microscopic and pathologic anatomy. But it is exactly a biological, psychological, social and new medical model that Western medicine is attempting to pursue. While Chinese medicine established its own system with this medical model two thousand years ago.

Chinese doctor doesn’t considers static anatomy as a starting point for understanding the diseases, and does not rely on detection equipments. On the contrary, Chinese doctor depends on the unique ways of TCM diagnosis to experience and study the human dynamic life information. Also it is based on syndrome differentiation to guide the disease therapy. This method not only can save a lot of examination fees for patients, but also can help doctors exchange with patients more closely, thus reflecting a real humanistic spirit.
