Traditional Chinese medicine has a history of several years. Its origin can be traced back to remote antiquity.In a long course of struggling against diseases, TCM evolved into a unique and integrated theoretical systcm of TCM. It is an important part of Chinese culture. More than 2,000 years ago, came out Huangdi's Classic on Medicine( Huang Di Nei jing 《黄帝内经》), which is the earliest medical classic extant in China.
Traditional Chinese medicine, one of China's splendid cultural heritages, is the science dealing with human physiology, pathology, diagnosis, treatment and prevention of diseases. Traditional Chinese medicine has its own specific understanding both in the physiological functions and pathological changes of the human body and in the diagnosis and treatment of disease. Traditional Chinese medicine regards the human body itself as an organic whole interconnected by zang-fu organs, meridians and collaterals.And TCM also holds that the human body is closely related to the outside world.In diagnosis, traditional Chinese medicine takes the four diagnostic methods ( inspection, auscultation and olfaction,inquiry), pulse-taking and palpation as its principal techniques. It als-o stresses the prevention and preventive treatment of disease, and puts forward such therapeutic principles as "treatment aiding at the root cause of disease". "strengthening vital qi and dispelling pathogens, regulating yin and yang and treating diseases in accordance with three condit-ions" (i. e. the climatic and seasonal conditiont, geographic localities and the patient's constitution).
