Introduction: The idea of health maintenance in the Yellow Emperor’s Classic of Internal Medicine involves the prevention of diseases before they occur, the treatment of diseases by following nature, the source of biochemistry by eating and drinking in a disciplined manner, the regulation of living in order not to make delusions of labor, and the regulation of emotions and will in order to nurture the body and the spirit, which is an important guidance for Chinese medicine to treat diseases before they occur. As early as the Yellow Emperor’s Classic of Internal Medicine (hereinafter referred to as “Nei Jing”), Chinese medicine has put forward the idea of preventing diseases before they occur, as stated in “Su Wen – Four Qi Tuning Shen Da Lun”: “Therefore, the sage does not treat the sick to treat the sick, and does not treat the chaotic to treat the chaotic, this is also called. If the disease has become a medicine after the medicine, chaos has become a cure after the cure, as if thirsty and wear well, bucket and cast cone, is not also late! . This idea of health care formed the theory of Chinese medicine to treat the untreated disease, “untreated disease” is not the absence of disease or visible disease, is the body of the yin and Yang, qi and blood, the imbalance of the internal organs of the Ying and Wei state. The idea of health maintenance in the Nei Jing is an important guideline for future generations of physicians in treating the untreated diseases. The importance of “preparing for a rainy day and preventing a disaster before it happens” was recognized in the Nei Jing. Su Wen – Eight Zheng Shen Ming Theory” put forward: “The upper work to save its sprouting teeth, must first see the three parts of the nine wait for the gas, all the regulation does not fail to save it, so it is called the upper work. The lower work to save its has-been, save its has been defeated.” The “Ling Shu – Inverse and Shun” also cloud: “The upper work, stabbing its unborn also. The next, stabbing its not yet in full bloom also. The next, stabbing its already decaying also. …… The upper work treats the unhealthy, not the already sick.” It is emphasized that the organism takes favorable measures to actively prevent disease before it occurs or before the onset of disease when the evil vapors are internalized, to take care of the righteousness and improve the organism’s ability to resist evil, so as to prevent the occurrence of disease and control the spread of disease, which reflects the idea of nourishing the body before it becomes ill. The “Nei Jing” mentioned the importance of health care and the rules of health care, as the “Su Wen – Shang Gu Tian Zhen Lun” said: “its know, law in the yin and Yang, and in the art of number, diet, regular living, not delusional labor ……”, suggesting that health care should follow the natural world It is suggested that we should follow the law of yin and yang changes in nature, use the correct method of health care, eat and drink with moderation, live and work with regularity, and do not deviate from the normal degree of labor, in order to achieve “the form and the spirit, and the end of its natural life, and a hundred years before leaving. This is the only way to achieve the goal of “being in good shape and in good health, and to live out one hundred years of life. If you go against this rule of health, but “to wine as a syrup, to delusion as a regular, drunk to enter the room”, and “to desire to exhaust its essence, to dissipate its true”, “do not know to hold full, do not know to control the gods, to fast its heart, against the birth of happiness “This is a clear indication of the different perceptions and attitudes of people towards health. The principles of health maintenance in the Nei Jing have a guiding meaning for the treatment of the untreated diseases. Externally, we should “avoid the evil spirits and wind, and avoid the invasion of disease causing factors from outside”. Internally, we should “be calm and void, and keep the spirit inside”, that is, we should know how to regulate the spirit and avoid excessive emotions and delusional depletion of essence, as the saying goes, “to have a leisurely mind and less desire, a peaceful heart and no fear, and a strenuous form and no fatigue”. To do “high and low do not adore each other”, “lust can not labor its eyes, lust and evil can not confuse its heart”, “not afraid of things”, so that “the true energy from the In this way, the true qi can be “followed” and “harmonized with the Tao”, so that internal and external harmony can be achieved and the purpose of prevention can be achieved before illness. The Nei Jing follows the laws of growth and collection in the four seasons of nature to regulate the spirit and life to treat the untreated diseases. As the book “Su Wen – Bao Sheng Quan Xing Lun” says: “Man is born with the qi of heaven and earth, and the law of the four seasons.” This is precisely the idea of the unity of heaven and man in the Nei Jing, which is a prerequisite for health care and the treatment of the undiseased. Human beings should follow the laws of nature and conform to the changes of spring temperature, summer heat, autumn cool and winter cold in order to avoid imbalance of yin and yang of the organism and reduce the occurrence of diseases. As the “Ling Shu – Shun Qi a day is divided into four times” said: “spring, summer growth, autumn harvest, winter storage. This is the norm of qi, and people should also respond to it.” This is also mentioned in the Nei Jing. The Nei Jing also mentions the method of health care in accordance with the changes of yin and yang in the four seasons, such as the Su Wen – Four Qi Tuning Shen Da Lun said: “Spring in March, this we hair Chen, …… night sleep and get up early, wide walk in the court, was hair slow shape, in order to make the Zhi Sheng, born and do not kill, give and do not take, reward and do not punish ……”, “in the summer of March, this is the Fanxiu, …… night sleep and get up early, not tired of the day, so that the will is not angry, so that the Huaying into the show, so that the gas can be released … …”, “Autumn March, this is called Rong Ping, …… sleep early and get up early, with the chicken, so that the will is peaceful, in order to slow down the autumn punishment, to collect the gods, so that the autumn qi is flat, no outside its will, so that the lung qi clear … …”, “March, this is called closed, …… early to sleep and late to rise, must wait for daylight, so that the will if the ambush if hidden, if there is a private intention, if you have got, go cold on the temperature. No leakage of the skin, so that the gas is taken away urgently ……”. The above is the way to maintain health in accordance with the four seasons of yin and yang. If you go against the four times of yin and yang changes, then internal injury to the five organs, and disease. As “Suwen – four qi tune Shen Da Lun” said: “spring in March, …… against it will hurt the liver, summer for cold change, Feng Chang less.” , “Summer March, …… rebellious is sad, autumn for cough malaria, the less the people who serve the harvest.” In March, …… the rebellion will hurt the lungs, winter for the food, less for the collection.”, “March, …… the rebellion will hurt the lungs, winter for the food, less for the collection.” In March, the …… rebellion will hurt the kidneys, spring for impotence and convulsions, the less the people who serve.” . The “spring and summer nourish Yang, autumn and winter nourish Yin” is an important principle of health care in accordance with the four seasons. For example, “Su Wen – Four Qi Tuning Shen Da Lun” said: “The four times of yin and yang, the fundamental of all things. So the sage spring and summer nourish Yang, autumn and winter nourish Yin, in order to from its root, so with all things floating in the door of growth. Against its roots, it is felled its original, bad its true carry on.” . Spring and summer are characterized by the flourishing of Yang energy, people should comply with the spring and summer at the beginning of the long gas to replenish Yang energy. And autumn and winter are characterized by calmness and convergence, its nature is Yin, people should comply with the collection of Qi in autumn and winter to replenish Yin and Jin. The “Su Wen – Shang Gu Tian Zhen Lun” mentioned in the rules of health care that “there is a diet in moderation”, that there is a difference between yin and yang in food, yin and yang in the human physique, and yin and yang in the climate, so adjusting the diet has a positive effect on adjusting the balance of yin and yang. Diet should be moderate, both clean, but also moderate, not bias, too hungry, too full, too cold, too hot, and not overeating. As the “Suwen – angry through the day on the chapter” said: “is the reason for the careful and five flavors, bone and tendons soft, blood to flow, coupled with dense, as is the bone to fine, careful way as the law, long have the life of heaven.” . In the spirit of the “five flavors” mentioned: “acid go tendons, eat more, people paralyzed; salty go blood, eat more, people thirsty; pungent go gas, eat more, people hole heart; bitter go bone, eat more, people become vomit; sweet go meat, eat more, people heart.” The above is enough to illustrate the importance of a disciplined diet in maintaining health and treating the undiseased. Diet is inappropriate, it can cause disease: too hungry is not enough food intake, biochemical lack of source of Qi and blood, weakness, followed by other diseases, such as “Ling Shu – five flavors” said: “so the valley is not into, half a day is the gas failure, a day is less gas carry on. . Excessive satiety will damage the spleen and stomach, the weakness of transport and transformation, “Suwen – paralysis chapter” in the cloud: “diet since the times, the intestines and stomach is injured.” The “Su Wen – angry Tong Tian Lun” said: “Thus eating and drinking, tendons and veins across the release, the intestines open for hemorrhoids, thus the large drink is a gas reversal.” . The lack of diet can lead to a variety of gastrointestinal diseases, such as “Suwen – strange disease theory” said: “fat people make internal heat, sweet people make full in the middle”. The diet is partial, can lead to yin and yang imbalance or certain nutritional deficiencies and illness, “Su Wen – angry through the day on” said: “the change of the sorghum, the foot born big ding.” , and as the “Ling Shu – division of the transmission” in the cloud: “food and drink, hot without burning, cold without Cang, cold and warm in the appropriate, so the gas will hold, is not to evil seclusion also.” . If you eat and drink in a disciplined manner, you will have a strong and healthy spleen, a source of Qi and blood biochemistry, and no disease due to Yin and Yang. The regularity of life and rest should be regular, and work should be limited. Normal labor and physical activities help the circulation of qi and blood and enhance physical fitness. Excessive exertion hurts the qi, excessive exertion hurts the spleen, and excessive room exertion hurts the kidneys. Excessive rest and relaxation is prone to poor blood flow, the spleen and stomach function is reduced, the body is weak. Such as “Suwen – Xuanming five gas chapter” said: “long vision injury blood, long lying injury gas, long sitting injury meat, long standing injury bone, long walking injury tendons, this is also called.” . Room health is particularly important. Suwen – yin and Yang should be the elephant in the room “said:” can know the seven losses and eight benefits, the two adjustable, do not know to use this, it is early decline of the section. . If the liver and kidney are full of essence and blood, life will appear vigorous and vital, and vice versa, aging and fatigue. The Nei Jing clearly states that “exhausting its essence” and “dispersing its truth” are the main mechanisms that promote aging. “The essence is the basic material of life activity, which can be transformed into qi and blood, filling the internal organs with inexhaustible source; and can strengthen the body externally. The Neijing also believes that the essence is hidden in the kidneys, such as the “Ling Shu – evil internal organs disease shape” said: “If into the room too much, …… is hurt kidney. Therefore, it is very important to moderate sexual intercourse and keep the essence of the liver and kidney. The Chinese medicine health treatment should focus on the spiritual will to the overall regulating effect, to achieve the shape of the gods together. Joy, anger, worry, thought, grief, fear and fright are the seven emotional changes, which are the state of human mental activity. If we keep our moods relaxed and our spirits happy, and do not overdo the seven emotions, we will be able to regulate our bodies, and our blood and energy will be calm and healthy. Suwen – Shanggu Tianzhen said “appropriate desire between the world, no rage and anger …… within the thought of the problem, in order to quietly happy as a matter of business, to self-gain for the work …… spirit is not scattered, but also can be a hundred numbers “. The Su Wen – Yin Yang Ying Xiang Daxue mentioned: “is the sage to do nothing, enjoy the ability of tranquility, from the desire to fast will in the abiding of nothingness, so the life span is infinite, with the end of heaven and earth, this sage’s governance of the body also”. The “Spiritual Pivot – The Organ” cloud: “The will and the will are the spirit of concentration and straightness. The soul is not scattered, and regret and anger are not allowed. The five organs are free from evil”, all pointed out the importance of regulating the emotions and will. Emotional and mental abnormalities, the body’s qi disorder, the internal organs of the yin and Yang Qi and blood disorder, resulting in disease. Such as “Suwen – lifting pain theory” cloud: “anger is gas up, happy is gas slow, sad is gas, fear is gas down, scared is gas chaos, thinking is gas knot ……”, “anger hurts the liver, happy sad, thinking hurts the spleen, worry hurts the lungs, fear hurts the kidneys “. Therefore, both the prevention and treatment of diseases should pay attention to the important role of God on the form, both to pay attention to the maintenance of the form, but also pay attention to the ingestion of the spirit, so that the form is strong, the spirit is abundant, the body and the spirit are in a harmonious and unified life process. The idea of nourishing the body and spirit in the Nei Jing is of great significance to the clinical guidance of Chinese medicine in treating the untreated diseases. To maintain health and treat the untreated diseases, we should follow the law of yin and yang, master the correct method, “the law of yin and yang, and in the art of number”, external to “false evil and thief wind, avoid it sometimes”, internal should be “calm and empty, the true energy from it “. We have to eat and drink carefully, not to make any delusional labor, to know how to hold fullness, to know how to control the spirit, so that the form and the spirit can be nourished together to achieve the purpose of treating the undiseased.
