Kidneys are located in the waist, one on each side (the left is the kidney and the right is the life gate), so “Su Wen - Pulse Essentials Essentials” says: “The waist is the capital of the kidney. The main physiological functions of the kidneys are to harbor the main essence, the main fire of the life gate, the main water, the main gas, the main bone, the medulla oblongata, and the brain. Kidney opening in the ear, the Division of the two yin, in the liquid for saliva. The kidneys have meridians and veins in the bladder, and the bladder and the bladder are mutually exclusive.
1. Kidney essence “essence” is a kind of subtle substance, the essence stored in the kidney is the kidney yin (true yin, yuan yin), is the basic material of the body's vital activities, which includes the innate essence and the essence of the innate. The innate essence, i.e. the essence of the organ, is the basic substance that constitutes life. It is endowed by parents and born before the body, and is closely related to the growth, development, reproduction and aging of the organism. The formation and development of the embryo use the kidney essence as the basic substance, and it is also the root of the material in the process of growth and development of the animal after birth. When the body matures, males have semen production, females have egg development, oestrus cycle, began to have the ability to reproduce; in old age, the kidney essence decline, reproductive capacity also declined, until disappeared. Acquired essence, that is, the essence of water and grain, by the five viscera, six internal organs, so also known as the “essence of the internal organs”, is to maintain the body's vital activities of the basic substances. The essence of the innate and the essence of the innate into one, mutual capitalization, interconnected. The essence of the innate depends on the essence of the innate to enrich the supply, the essence of the innate need to fund the essence of the innate in order to be born, so the exhaustion of one side will inevitably affect the function of the other side.
The Kidneys store essence, meaning that the production, storage and transfer of essence are all controlled by the Kidneys. The essence stored in the kidney is transformed into kidney qi, which is transmitted through the triple jiao and spreads throughout the body to promote the growth, development and reproduction of the body. As a result, impotence, spermatorrhea and infertility are directly related to the kidneys.
2. Kidney master of the fire of the gate of life gate, that is, the fundamental meaning of life; fire, refers to the function. The fire of the gate of life, generally known as yuanyang or kidney yang (true yang), is also hidden in the kidneys. It is both the driving force behind the physiological functions of the kidneys and the source of heat energy in the body. The fire of the vital gate, which is mastered by the kidneys, refers to the yuan-yang of the kidneys, which has the function of warming the five viscera and six bowels and maintaining their vital activities. The essence of the kidney needs to be warmed by the fire of the life gate in order to play its role in nourishing the tissues and organs and reproduction of offspring. Five organs, six functional activities, but also depends on the kidney Yang warming to normal, especially after the spleen and stomach need to be warmed by the innate fate of the fire, in order to better play the role of transportation. Therefore, insufficient fire at the Gate of Life often leads to a decline in yang qi throughout the body.
Kidney yang and kidney yin summarize the two aspects of the physiological function of the kidneys, kidney yin on the body organs play a moist moisturizing and nourishing role, the kidney yang plays a warming and biochemical role, the two are mutual constraints, interdependence, to maintain a relative balance, or else there will be a kidney yang or yin deficiency of the pathological process. Since the essence of both kidney yang deficiency and kidney yin deficiency is the deficiency of kidney essence, kidney yang deficiency to a certain extent can involve kidney yang, and vice versa, kidney yin deficiency can also injure kidney yin, and even lead to kidney yin and kidney yang deficiency. Clinically, the main difference between renal yin deficiency and renal yang deficiency is “internal heat in yin deficiency” and “external cold in yang deficiency.
3. Kidney water refers to the kidney in the body of water metabolism process plays the role of ascending clear and descending turbid. Water metabolism process in the animal body by the lungs, spleen, kidney organs to complete, in which the role of the kidney is particularly important. Suwen - the theory of the inverse regulation, said: “the kidney, water organs, the main fluid.” The function of the kidneys as the master of water is mainly accomplished by the vaporization of the water fluid by the kidney yang (the fire of the life gate). Water into the stomach and intestines, from the spleen up to the lungs, the lungs will be clear in the clear part of the transmission of the whole body, and clear in the turbid part of the lungs through the purging and downward action downstream in the kidneys, the kidneys and then to be divided into clear urinary turbidity, will be turbid in the clear through the reabsorption of the uptake of the lungs, turbid in the turbid useless part of the downstream injection of the bladder, and discharged out of the body. Kidney Yang on the water vaporization effect, known as “gasification”. If the kidney yang is insufficient, the fate of fire failure, gasification disorder, will cause water metabolism disorder and edema, hydrothorax, ascites and other symptoms.
4. Kidneys are responsible for the absorption of qi, which has the meaning of receiving and taking in. Kidney main gas, refers to the kidney has to take in the breath of the gas, to assist the lung Division respiratory function. Breathing by the lungs, but the inhalation of gas must be down to the kidneys, in order to make breathing uniform, so there is a “lungs main breath, kidney main gas” said. From the relationship between the two, the lungs Division breathing, for the root of the gas; kidney main gas, for the root of the gas. Only sufficient kidney qi, the energy is fixed in the lower, in order to gas normal; if the kidney is weak, the root is not solid, the gas is not normal, will affect the lungs of the purging, there are more than inhalation, inhalation difficulties wheezing of the disease.
5. Kidney is in charge of bone, marrow and brain, which means that kidney is in charge of bone metabolism, nourishing and nourishing bone marrow, spinal cord and brain. The essence stored in the kidneys has the function of generating marrow, which fills the bones and nourishes them, and the bones rely on the marrow to be strong, which is also an aspect of the function of the essence of the kidneys in promoting growth and development. This is also an aspect of the function of the kidney essence to promote growth and development. If the kidney essence is sufficient, there will be a source of the marrow. Bones are strong and powerful; if the kidney essence is deficient, the source of marrow is insufficient and cannot nourish the bones, which can lead to poor bone development and even symptoms such as brittle and weak bones. Therefore, “Suwen - yin and yang should be like a great theory” said: “the kidneys produce bone marrow”, “Suwen - to solve the essence of the theory” also said: “the marrow, the bone of the full also”.
Medulla oblongata is produced by the kidney essence and is divided into bone marrow and spinal cord. The spinal cord passes up to the brain and gathers to form the brain. Therefore, The Spiritual Pivot - Sea Theory says: “The brain is the sea of the marrow”. Brain presides over the mental activity, so it is also called “the house of the spirit”, but it needs to rely on the kidney essence to nourish, otherwise there will be dementia, the call should not be seen, the eyes can not see, tired and sleepy and other symptoms.
Kidney main bone, “teeth for the bone of the rest”, so the teeth also rely on the kidney essence of nourishment. Kidney essence is sufficient, the teeth are strong; kidney essence is insufficient, the teeth are loose, or even fall off.
Suwen - the theory of the generation of the five organs” pointed out that: ‘the kidney and bone, and its honor hair’. The growth of animal coat, its nutrition comes from the blood, and the vitality is rooted in the kidney qi, and for the kidneys outside. The glory of the coat is related to the prevalence of the essence of the kidneys. If the kidney essence is sufficient, the coat will grow and shine, and if the kidney qi is weak, the coat will wither and even fall off.
6. The kidneys open the orifices in the ears, and the upper orifices of the kidneys are the ears. The ear is an organ of hearing, and its function depends on the nourishment of kidney essence. Kidney essence is sufficient, the hearing is sensitive, so the “Spiritual Center - the pulse of the chapter” said: “Kidney gas through the ear, kidney and the ear can hear the five tones carry on”. If the kidney essence is insufficient, it can cause tinnitus, hearing loss and other symptoms, so “Anji set - broken gold five organs theory” said: “kidney congestion deafness is difficult to hear things, kidney deficiency ear like listening to cicadas.”
The lower orifices of the kidneys are the two yin. The two yin are the anterior yin and the posterior yin. The anterior yin has the functions of urination and reproduction, and the posterior yin has the function of excreting feces. These functions are directly or indirectly related to the kidneys, such as the body's reproductive function by the kidneys; urination in the bladder, but depends on the qi of renal yang; fecal excretion through the back of the yin, but also subject to the influence of the warming effect of renal yang. If the kidney yang is insufficient, the fire of the life gate is weak, can not warm the spleen yang, can lead to loose feces. In addition, insufficient kidney yang can also cause frequent urination, impotence and other symptoms.
