Righteousness and evil are two contradictory aspects. The function of healthy qi is a comprehensive reflection of the normal function of qi and blood in human organs. Sufficient healthy qi, strong disease resistance, even if there is invasion of foreign evil, it will not cause disease. Insufficient healthy qi leads to weak disease resistance, and exogenous pathogens are easy to invade and cause disease. Therefore, the deficiency of vital qi is in a dominant position in the process of disease production, and the rampant exogenous pathogens must be based on the deficiency of vital qi. This is the first meaning of "keeping healthy qi inside, and evil cannot be done". Once the disease occurs, the development trend of the disease is determined by the contrast between the strength of healthy qi and evil qi. Strong healthy qi, weak evil. Evil spirits can't go deep; On the contrary, the evil forces are pressing hard step by step, from shallow to deep. This is its second meaning.
The pathogenesis of traditional Chinese medicine attaches importance to vital qi, but it does not rule out the important role of pathogenic factors in the occurrence of diseases. Even under certain conditions, such as snake bites, snake venom, as a powerful exogenous evil, has obvious advantages compared with the strength of vital qi in human body. No matter how upright I am at ordinary times, I can't get rid of it The same is true of other serious infectious diseases such as cholera, hepatitis, high temperature, high voltage current and chemicals. Therefore, Su Wen's posthumous works and acupuncture theory emphasize "avoiding the poisonous gas" while putting forward "keeping the healthy qi in the interior and not doing evil". It can be seen that the more important significance of "keeping healthy qi inside and not doing evil" is to ask people to protect healthy qi and avoid the invasion of evil spirits. In ancient times, there were many methods of "keeping vital qi inside", such as "being indifferent, obeying the true qi, keeping the spirit inside, and never getting sick" (Su Wen Shang Ji Naive Theory); Yin and Yang have four seasons, such as "nourishing Yang in spring and summer, nourishing Yin in autumn and winter"; ("Su Wensi Qi Diao Shen Da Lun"); There are also dietary adjustments, such as "harmony with five evils, strengthening bones and muscles, and promoting qi ..." ("Su Wentong's Theory of Wondering Heaven"). And qigong guidance, acupuncture and other methods. Its purpose is to keep healthy qi, prevent diseases and prolong life.
The viewpoint that "healthy qi should be kept inside, and evil should not be done" is also of guiding significance to the treatment of diseases. To treat diseases, we need to weigh the contrast between healthy qi and evil qi and adopt corresponding treatment methods. But they all focus on protecting the healthy qi of human body. For example, if evil prevails over positive decline, or if you are in a hurry, you can treat it, eliminate evil and protect the right, or strengthen the body and eliminate evil, or strengthen the body and eliminate evil. Used for colds, fever, aversion to cold, fatigue, spontaneous sweating, thready pulse, etc. Sweating and relieving exterior syndrome is often ineffective, but Shensu drink is effective in strengthening body resistance and relieving exterior syndrome.
To sum up, a correct understanding of the connotation of "healthy qi exists inside, and evil cannot be done" should include: first, it shows that the occurrence of diseases is the result of the struggle between good and evil, and healthy qi plays a leading role and plays a major role. Secondly, it is pointed out that in the process of disease development, healthy qi determines the development trend of disease. Thirdly, it is revealed that protecting healthy qi and avoiding its toxic gas are the basic principles of health and longevity. It embodies the idea of putting prevention first. Fourth, guide people to pay attention to protecting healthy qi at all times in clinic.
