Analysis of True Yin and True Yang Theory

True Yin and True Yang are also called Yuanyin and Yuanyang, and True Water and True Fire are also called Kidney Yin and Kidney Yang. The original meaning of "truth" is "origin, itself." For example, "Zhuangzi." "Qiu Shui" says: "Be careful and don't lose, which means going against the truth." And "Shan Mu" says: "See the benefits and forget the truth." "Yuan" means the beginning, the first. "The Story of Gongyang." "Yin Gong Nian" says: "What is the first year? The first year of the king." "Shuowen Jiezi" says: "Yuan, the beginning."

The names of Zhenyin and Zhenyang come from Yu Mingmen theory. Physicians of all ages have different understandings of the Mingmen theory. "Nei Jing" says that "the gate of life is the eye" ("Lingshu. Genjie"); "Nanjing" believes that the gate of life is one of the internal organs of the human body, pointing out that "the two kidneys are not both kidneys, and the left side is the kidney." The one on the right is the kidney, and the one on the right is the gate of life" ("Difficulties Sutra. Thirty-six Difficulties"). Since the "Difficult Classic", doctors of all ages, especially those in the Ming and Qing Dynasties, have conducted in-depth discussions and research on the theory of life gate, and have put forward many different opinions: either the right kidney is the gate of life, or the two kidneys are the gate of life. The gate may be between the two kidneys as the gate of vitality, or the gate of vitality may be the qi movement between the kidneys, or the gate of vitality may be the house of water and fire, etc. There are different opinions and there is no consensus. Despite this, people have basically the same understanding of the function of Mingmen, that is, they believe that Mingmen is the root of life, the house of water and fire, containing true yin and true yang, and is the foundation of human life activities. Just like "The Difficult Sutra." "Thirty-nine Difficulties" said: "The door of life is where the spirit is given up." Zhang Jingyue said in "Lei Jing Fu Yi". Please record it correctly. "Three Burners Envelop Mingmen Analysis" says: "Therefore, Mingmen is the house of water and fire, the house of Yin and Yang, the sea of ​​essence and energy, and the sinus of death and life." The function of Mingmen is closely related to the kidneys, "Mingmen Otherwise, its Qi and kidneys are connected" ("Difficulties Classic. Thirty-nine Difficulties"). "The fire of the life gate is called vitality; the water of the life gate is called the essence." ("Leijing Fuyi. Zhenyin Lun") It can be seen that the function of the life gate is related to the vitality. Therefore, Yu Tuan, a physician in the Ming Dynasty, said in "Medicine or Questions": "Both kidneys are the root of the true essence, and are related to life and life. Although they are water organs, there is actually fire contained in them." Qin Bomo clearly pointed out: "Mingmen is the root of life, including true yin and true yang producing qi, which reaches the brain through the organs and meridians, connects the bone marrow to the four ends, warms the skin and interstitial tissues, etc., and plays a leading role in maintaining the life activities of the human body."

The kidney is the foundation of innateness and is closely related to the generation of vitality. The essence in the kidneys is the foundation of human life activities. It can be inferred from this that kidney yin and kidney yang are true yin and true yang. Kidney yin is true yin, primary yin, the water of life gate; kidney yang is true yang, primary yang, the fire of life gate. Since the water and fire of Mingmen are the foundation of yin and yang in the body, kidney yin and kidney yang are also the foundation of yin and yang of various internal organs of the human body, and play an important role in maintaining the functional activities of the human internal organs. “The yin qi of the five internal organs cannot be nourished otherwise; Yang Qi cannot develop otherwise." ("Jingyue Quanshu. Chuanzhonglu. Mingmen Yuyi")

Kidney yin and kidney yang are mutually opposed and restrictive in the human body, but they are also interdependent and interdependent. For use, it can simultaneously maintain the physiological state of the human body's "Yin Ping Yang Secret". Therefore, it is said that "Human water and fire are yin and yang, that is, qi and blood. Without yang, yin cannot be born, and without yin, yang cannot be transformed" ("Yin Zong Must Read"): "Yin and yang are originally the same air, and fire is water. The Lord, water is the source of fire, and water and fire are not separated from each other." ("Jingyue Complete Book"). If internal and external evil spirits act on the human body, destroying the state of "Yin Ping Yang Secret", causing the yin and yang of the kidneys to lose coordination and balance, leading to pathological conditions of kidney yin deficiency, kidney yang deficiency, or both kidney yin and yang deficiency. Deficiency of kidney yin can cause symptoms such as hot flashes and night sweats, dizziness and tinnitus, nocturnal emission in men, and dreams of intercourse in women. Insufficient kidney yang can cause symptoms such as fatigue, cold limbs, backache and frequent urination, impotence and premature ejaculation in men, and cold uterine infertility in women. If the clinical syndrome shows kidney deficiency without obvious signs of cold or heat, it is called "deficiency of kidney essence" or "deficiency of kidney qi". Since both kidney yin and kidney yang are based on the essence of the kidney, a deficiency of kidney yin or kidney yang to a certain extent can often affect the opposite party, causing damage to yin to yang, or damage to yang to yin, and eventually Symptoms of Yin and Yang deficiency.

Since kidney yin and kidney yang are the true yin and true yang of the human body, and are the foundation of yin and yang of various organs, the imbalance of yin and yang in the kidney will not only cause diseases of the kidney itself, but also affect the yin and yang of other organs, resulting in Corresponding illness.

If kidney yin is deficient and cannot nourish liver yin, it can lead to liver and kidney yin deficiency, hyperactivity of liver yang, or internal movement of liver wind; if kidney yin is insufficient and cannot support heart yin, it can lead to heart and kidney yang deficiency and heart fire. Syndrome of upper inflammation; if kidney yin is deficient and cannot nourish lung yin, then the syndrome of lung and kidney yin deficiency will be seen. If the kidney yang is insufficient and the spleen yang cannot be warmed, it may lead to spleen and kidney yang deficiency, and water-dampness may occur, or water vapor may overflow. If the kidney yang is deficient and the heart yang cannot be warmed, it may lead to heart and kidney yang deficiency. On the contrary, if the yin and yang of other organs are deficient, and over time it will affect the kidneys, it will also cause the yin and yang deficiency of the kidneys.

Clinically, for symptoms caused by kidney yin and kidney yang deficiency, we should follow the method of treating the disease and seeking the root cause, identifying the syndrome, seeking the cause, and examining the cause to treat it. Since kidney yin and kidney yang are true yin and true yang, for the syndrome of kidney yin deficiency, the best choice is to use thick and greasy medicine to nourish yin and nourish the kidney; for the syndrome of kidney yang deficiency, the best choice is to use medicine with thick qi and heat. , to warm the yang and nourish the kidney; if the kidney essence is deficient, or the kidney qi is insufficient, use the products of flesh and blood to nourish the kidney and essence, or tonify the kidney and replenish qi; if the kidney yin and kidney yang are deficient and the yin and yang of other organs are insufficient, Corresponding drugs should be added or subtracted to treat it. Since true yin and true yang are mutually beneficial and influence each other, clinically, for syndromes of kidney yin deficiency, kidney yang deficiency, or both yin and yang deficiency, "yang disease treats yin" and "yin disease treats yang" , or the methods of "seeking yin from yang" or "seeking yang from yin" can be used to treat it, which is the so-called "strengthening the master of water to control the sun" and "benefiting the source of fire to eliminate the yin shadow" ("Yellow Emperor's Internal Classic Su Wen" ). "This is also the wonderful effect of yin and yang complementing each other. Therefore, those who are good at replenishing yang must seek yang from yin, and yin will get the help of yin and its life and transformation will be endless; those who are good at replenishing yin must seek yin from yang, and yin will get yang to rise. The fountain is endless." ("Jingyue Complete Book. New Fang Balue")
