It was Chen Wuze who proposed the theory of three causes.

The main contents of "The Theory of Three Causes":

1. Explain the three causes.

Inspired by the theory of etiology in "Nei Jing" and "Synopsis of the Golden Chamber", Chen elaborated on the "Three Causes Theory" in combination with clinical treatment, pointing out that "the six evils are the normal qi of heaven, and the It first flows from the meridians, and internally combines with the internal organs, and is caused by external factors. It is the normal nature of the Qi Qin that when it moves, it first appears from the internal organs and is caused by internal factors. It is like being hungry or full due to food, which is called breathing injury. . Excessive physical exertion, yin and yang disobedience, and even sores, disobedience, pressure and drowning are not the so-called internal and external causes. Cold, heat, rheumatism, and plague qi are all external causes. "It can be seen that Chen listed the six evils and plague qi as external causes. Injuries caused by the seven emotions are internal causes, while eating, fatigue, injuries from servants, insect poisoning, etc. are not classified as internal and external causes. these three causative factors.

It can cause disease alone or together, and they are not completely separated from each other. In addition, Chen believes that pathological products are formed after three causes of disease, such as phlegm, blood stasis, etc. It can also be used as the cause of different diseases and syndromes.

2. Dialectical emphasis.

While studying the three causes in detail, Chen Wuze also attached great importance to pulse examination and syndrome differentiation, emphasizing that to learn medicine one must know "pulse, disease, syndrome, treatment, and their causes." Diseases can be identified based on the pulse. Diagnose the disease based on syndrome and treat according to the syndrome. On the basis of previous theories, he proposed the method of diagnosing the pulse by "dividing people into the mouth to identify internal and external causes; listing nine points to describe injuries and illnesses".

Checking the pulse must be based on the internal and external causes of the person's breathing, which Chen believes is "the key to medical diagnosis." The diagnosis method is to divide the left hand in front of the body to welcome people. Wait for the six external emotions. The right hand closes the front part and divides it into a breath opening. The seven emotions are internal injuries; they should not be greeted by others or vented. There are no internal or external causes. However, it is better to say that the left and right guanqian are divided into internal injuries and external infections, not as good as the internal organs.

The so-called "Nine Ways in the List". The 24 pulses are divided into "seven surface disease pulses" of floating, smooth, slippery, solid, stringy, tight and flood, "eight-mile disease pulses" of slight, heavy, slow, astringent, late, subdued, wet and weak, and thin, There are three types of disease pulses: counting, movement, deficiency, acceleration, knotting, dispersion, change and generation of "nine disease pulses". At the same time, Chen also pointed out that "the twenty-four characters of "Bo" are not excessive at all: "Yu" refers to floating, sinking, delaying, and counting.

To summarize the outline. Therefore, we know that floating is wind, sinking is wet, and solid ; Chi means cold, means heat; means rheumatism, cold and heat are external, and deficiency, cold and dryness are internal. The beginning of identifying the cause. No more than pulse. "
