What is the main exposition of Yin and Yang theory in Huangdi Neijing?

1. Discussed the meaning and function of three Yin San yang, as well as their relationship, symptoms and pulse conditions.

Secondly, the relationship between the prognosis of the disease and the four seasons yin and yang is discussed.

From Meng Chun to the Yellow Emperor, Emperor Yan sat and watched the Eight Extremes, asking God for thunder; Yin and yang and so on, the way of meridians, dominated by five, what is the most expensive and dirty? Lei Gong said: Spring, A, B and Qing, the middle governs the liver, and when its main pulse lasts for 72 days, its viscera is the most expensive. The emperor said: but reading the upper and lower classics, yin and yang are peaceful, and the words are expensive. At the bottom.

Lei Gong went to fast for seven days, and then he stayed for a while. The emperor said: Three yang is the meridian, two yang is the dimension, and one yang is the line, so we know that the five internal organs begin and end. Three yin is the exterior, two yin is the interior, and one yin is the best, but it is also reasonable. Lei Gong said: I am not clear about my occupation.

The emperor said: the so-called three yang, the sun is the meridian, the hand three yang pulse is too cloudy, the string floats but not sinks, it is determined by the degree, the heart is examined, and the yin and yang are combined. The so-called two yang, Yangming also, until the hand is too cloudy, the string is heavy and anxious, and he dies. One yang, less yang, to the hands of the lunar, even people meet, strings are hanging, the disease of less yang, only yin will die.

Sanyin people, the master of the Six Classics, are also too lunar, staying on the drum but not floating, and aiming at the sky. The second yin reaches the lung, and its qi belongs to the bladder, which is connected with the spleen and stomach. One yin is unique, the classics are unique, the air floats without bulging, and the hook is slippery. Six-pulse patients are yin and then yang, belonging to the same family. Miao Tong's five zang-organs are in harmony with Yin and Yang, giving priority first, then serving as guest.

Lei Gong said: I know myself best. I am taught by meridians. I praise the way of peace, which is in line with peace. I don't know yin and yang, I don't know gender. The emperor said: three yang is the father, two yang is the guardian, and one yang is the discipline; Three yin is the mother, two yin is the woman, and one yin is the sole envoy.

Two yang and one yin, Yangming governs the disease, while one yin is invincible, soft and moving, and all nine orifices are heavy. Three yang and one yin, the sun pulse wins, one yin can not stop, five dirty, foreign fear. Two yin and two yang, the disease is in the lung, less yin and heavy pulse, lung failure and spleen injury, four branches of trauma. Yin and yang are combined, the disease is in the kidney, swearing, and being crazy. Two yin and one yang, the disease comes from the kidney, and the yin-qi guest swims in the stomach cavity, gets down to the empty embankment, is blocked, and the four branches are separated. One yin and one yang replaced the absolute. This Yin Qi goes straight to the heart and changes up and down. I don't know what to get in and out. The throat is dry and the disease lies in the spleen. Two yang and three yin exist, but yin is not as strong as yang. Yang Can does not control yin, but yin and yang are combined, floating like boils and sinking like pus elbows. Both yin and yang are strong, down to yin and yang. Shanghe Zhao Zhao, a total of diagnosis of life and death, and then the year.

Lei Gong said: Please be the same as the short line. The yellow emperor should not. Tripterygium wilfordii asked. Huangdi said: In Confucian classics. Lei Gong said: Please smell the short term. The yellow emperor said: diseases related to yang in winter and March, and signs of death in the first month of spring all belong to spring. In winter and March, the disease has been exhausted, the grass withered and the willow leaves withered, and in spring, Yin and Yang died, and the period was in Meng Chun. The disease is in spring and March, and the sun shines high: killing, yin and yang, and the period is in the grass. Three diseases in summer are in the month, but it will be cloudy for ten days; Yin and Yang cross, and the period is in water. The disease rises in autumn, winter and March, and cannot heal itself. Those who have intercourse with yin and yin cannot sit up, and the three yang are the only ones. Two yin alone, expired water.

On this day in beginning of spring, the Yellow Emperor sat leisurely, looking in all directions, waiting for the direction of the Eight Winds, and then asked Lei Gong: According to the yin-yang analysis method and the meridian theory, which do you think is the most expensive to cooperate with the five internal organs? Lei Gong replied: Spring is the first year, it belongs to A-B wood, its color is blue, and the liver is dominant in the five internal organs. On the 72nd day of spring, the liver is flourishing, which is also the time when the liver pulse is in season, so I think the liver is the most expensive. The Yellow Emperor said: I learned from the comparative analysis theory of Yin and Yang of Shang and Xia Jing. What you think is the most expensive is the lowest.

Lei Gong fasted for seven days and sat beside the Yellow Emperor in the morning. The Yellow Emperor said: Three Yang is the classics, two Yang is the dimension, and one Yang is the action. Knowing this, we can know the end point of the operation of qi in the internal organs. Three yin is the exterior, two yin is the interior, one yin is the end of Yin Qi, and the other yin is the beginning of Yang Qi, just like the junction of new moon and gray, which accords with the truth that Yin and Yang of heaven and earth end. Lei Gong said: I haven't understood the meaning yet. The Yellow Emperor said: The so-called "Sanyang" refers to the sun. As for the pulse, the hand is too cloudy and the mouth is too deep. When you see the string floating but not sinking, you should judge it according to the constant degree, observe it attentively, and combine the theory of Yin and Yang to show its quality. The so-called "Yang Er" is Yangming, whose pulse is dark in the mouth. When the string is heavy and urgent, he does not strike his fingers. In hot weather, it has this pulse, and most of them are in danger of death. "One Yang" is shaoyang, and its pulse is too cloudy to touch the mouth, even when people meet it, the strings hang endlessly. This is the pulse of shaoyang meridian. If you see a very dirty pulse with only yin and no yang, you will die. "Yin San" is the lung meridian of the lunar hand, and the lung faces hundreds of pulses, so it is the master of the six meridians. Its qi enters the mouth of the Taiyin, and its pulse is heavy, agitated and not floating. It is the spirit of the Moon that sinks and cannot rise, leading to emptiness of mind. "Er Yin" refers to Shao Yin, its pulse refers to the lung, and its qi belongs to the bladder, which is connected with the spleen and stomach. "One Yin" is Jueyin, and its pulse is only deep in the mouth of Taiyin, and the menstrual qi is exhausted, so the pulse is floating but not bulging, and the pulse is smooth as a hook. The above six kinds of pulse conditions, or the yang viscera sees the yin pulse, or the yin viscera sees the yang pulse, cross each other and converge at the mouth of the inch, all of which are connected with the five internal organs and are in harmony with the yin and yang. If there is such a pulse, the first person who appears at the entrance of the village is the guest.

Lei Gong said: I have fully understood your meaning. Combined with the meridian principle you taught me before, the leisurely way I read in the book and the leisurely way you talked about today, I still don't understand the meaning of Yin and Yang. The Yellow Emperor said: Sanyang is like a father, Yang Er is like a defender, and Yiyang is like a hub; Yin San is as good at nurturing as a mother, Er Yin is as good at defending as a woman, and Yi Yin is like a messenger, who can communicate with Yin and Yang.

Two yang and one yin are the main diseases of Yangming. If two yang can't overcome one yin, Yangming pulse will be soft and qi of nine orifices will stagnate. When three yang and one yin are diseases, the sun pulse prevails and cold water is full of qi. A yin and liver qi can't stop the cold water, and the five internal organs are disturbed, showing panic. Two yin and two yang are diseases in the lung, with less yin and heavy pulse, and less yin is stronger than the lung and hurts the spleen, but in trauma and limbs. When the two yin and yang interact, the soil pathogen will invade the water, and its disease lies in the kidney, cursing and reckless behavior, and epilepsy will be frantic. Two yin and one yang, the disease comes from the kidney, and Yin Qi goes against the heart, so that the stomach cavity is blocked like a dam and the limbs can't be used in vitro. One yin and one yang are diseases, and the pulse is replaced by the pulse. This is a heart disease caused by the qi of Jueyin, or in the upper or lower part, with no fixed place to live, tasteless diet, excessive stool and diarrhea, dry throat and spleen disease. Two yang and three yin are diseases, including yin and spleen. Yin Qi can't reach Yang, and Yang Qi can't reach Yin. Yin and Yang are isolated from each other. When the yang floats outside, it becomes bloody inside, gloomy inside and abscess outside. If the qi of yin and yang is strong and the pathological changes tend to decline, men will get sick in the yang meridian and women will get sick in the vagina. Looking up at the astronomical phenomena and overlooking the geography, we must decide the death and life cycle of patients based on the theory of yin and yang, and at the same time, we must consider the spirit of the New Year.

Lei Gong said: Can you tell me the date of death of this disease? Huangdi didn't answer. Lei Gong asked. Huangdi said: There are explanations in medical books. Lei Gong added: Can you tell me the date of death of this disease? The Yellow Emperor said: If the symptoms and pulse conditions in March in winter are full of yang, then the pulse conditions in the first month of spring will die, and then when spring enters summer, when the yang is full and the yin is declining, there will be a danger of death. According to heaven, illness in winter and March will inevitably exhaust, and grass and willow leaves will die. If both Yin and Yang die in spring, then they will die in the first month. Onset in March in spring is called "killing Yang". Both yin and yang die, and the time of death is when the vegetation dries up in winter. If the disease does not heal in March in summer, when it reaches cloudy day, then its death period will not exceed ten days after cloudy day; If the pulse sees alternating yin and yang, the death period is when the ice is thin in early winter. Winter and March disease, hand and foot three-yang pulse syndrome, cured without treatment. You can't sit up when yin and yang intersect and become a disease. If the Sanyang pulse is single, then the Yang is single and there is no yin, and the death period is when the ice is like a stone. When the three yin veins are alone, the yin is alone and there is no yang, and the death period is in the rainy day of the first month.
