Chen Yan (1121-1190), a native of Qingtian, was born in the Northern Song Dynasty and died in the Southern Song Dynasty. Chen Yan was a famous master of traditional Chinese medicine in the Song Dynasty, who advocated the idea of "returning from Bo to the covenant", and put forward the "Three Causes Theory", clarified the basic theory of the etiology of Chinese medicine, developed the etiology of Chinese medicine into an independent discipline, and made great contributions to Chinese medicine, and was listed as one of the 22 famous doctors of the Tang, Song, Jin and Yuan dynasties by later generations. His masterpiece "Three Causes and Prescriptions" became the theoretical basis of the Yongjia School of Medicine, and therefore, he also became the founder of the Yongjia School of Medicine.
Chen Wuxue has been a superman since he was a child, and he began to learn medical skills when he was a little older. He is particularly fond of learning, especially like to organize all kinds of classics, and he advocates erudition and etiquette, and learning from things. He is extremely rigorous in his studies, respects the ancients but not the ancients, is good at innovating according to clinical practice, and has his own unique views on diseases.
Chen Wuxue experienced the demise of the Northern Song Dynasty and had a huge impact on his outlook on life, so he devoted himself to medicine, devoted himself to the study of medical classics and medical prescriptions of the past dynasties, and accumulated thick and thin hair. Therefore, he had a very great influence and high popularity during the Southern Song Dynasty.
Inspired by the "Neijing" and "Jin Kui Yaolu", Chen Wuxue elaborated the "Three Causes Theory" in detail based on his clinical treatment experience. He listed the six evils, plagues, and seasons as the external causes of diseases, the injuries caused by the seven emotions as internal causes, and the internal and external causes of eating and drinking, and the poison of servants, wounds, insects, etc. These three pathogenic factors can cause disease alone or at the same time, and the three are not completely separated. In addition, Chen Yan believes that the pathologies caused by the "three causes", such as phlegm drinking, blood stasis, etc., are different symptoms caused by the etiology.
While studying the "Three Causes Theory" in detail, Chen Wuxue emphasized that the study of medicine must recognize the unity of "pulse, disease, syndrome, and treatment".
Chen Wuxue is also a well-known clinician, he is proficient in the vein, the medical skills are very sophisticated, and he is known for being good at treating incurable diseases.
At the same time, his academic attainments are extremely profound, and he summarizes his thoughts and experiences, and has written a lot. Therefore, not only are there many people seeking medical treatment, but also many people are also very interested in studying medicine.
In his book "Three Causes and Prescriptions", he systematically proposed for the first time that the "seven emotions" are the internal causes of disease, and elaborated on the pulse, symptoms and treatment methods of diseases caused by abnormal emotions, marking the maturity of the "Seven Emotions Theory". The influence of the "Seven Emotions Theory" is very far-reaching, and to this day, the Seven Emotions of Internal Injuries are still the basic method of etiological analysis. Especially in the fast-paced and high-pressure lifestyle of modern society, psychological problems are more likely to occur, and Chen Wuxue's "Seven Emotions Theory" is more realistic.
"Three Causes" inherits and enriches the doctrine of etiology in "The Yellow Emperor's Neijing" and "Treatise on Typhoid Fever and Miscellaneous Diseases", and for the first time distinguishes the etiology into three categories: "external causes, internal causes, and not internal and external causes".
"Three Causes" combines clinical and three causes, so it has very important reference value for the study of etiology, pathology and clinical practice of traditional Chinese medicine.
