What does the kidney in traditional Chinese medicine mean?

According to the theory of traditional Chinese medicine, kidney belongs to the five internal organs (note: five internal organs: heart, liver, spleen, lung and kidney). One of them is the innate foundation of the human body (note: essence is the basic substance that constitutes the human body, and it is also the material basis for human growth and development and various functional activities. Congenital essence is born by parents and is the original substance that constitutes the human body. In the process of embryo development, it is the original material that constitutes the embryo and the foundation of life, so it is called "innate essence". Because the innate essence is only hidden in the kidney, the kidney is called the "innate foundation". ) plays a vital role in human growth, development and aging. According to the theory of "wood, fire, earth, gold and water" (note: the five elements are the movements and changes of five substances: wood, fire, gold, earth and water. Liver belongs to wood, heart belongs to fire, spleen belongs to earth, lung belongs to gold, and kidney belongs to water. ), the kidney, heart, liver, spleen and lung form a whole. Kidney and Bladder Meridian Exterior and Interior (Note: Kidney Meridian of Foot Shaoyin and Bladder Meridian of Foot Taiyang are interrelated and belong to both kidney and bladder meridian, so they are exterior and interior, so kidney and bladder meridian are collateral exterior and interior. The gasification function of bladder depends on the rise and fall of kidney qi, which helps bladder to gasify body fluids. ), enlighten the ear (note: the sensitivity of hearing is closely related to the profit and loss of essence in the kidney. When the kidney is full of essence, the brain will be nourished, the hearing will be sensitive and the resolution will be high. On the other hand, when the kidney essence is insufficient, the brain can not get enough nutrition, and hearing loss, tinnitus and even deafness will occur. )。 Kidney can store essence (note: kidney can store essence. ), the main growth and reproduction (note: kidney essence is the original material of embryo development, and can also promote the maturity of reproductive function. After birth, due to the mutual nourishment of innate essence and acquired essence, kidney essence gradually fills up from childhood and develops to a certain stage, producing a substance that promotes the maturity of reproductive function-"Tiangui". Under the action of "Tiangui", men can produce semen, while women have menstrual cramps on time, and their sexual function is gradually mature and they have reproductive ability. Later, with the decline of kidney essence, the output of "Tiangui" decreased, even gradually dried up, and the reproductive capacity also decreased, leading to loss. This fully shows that kidney essence plays a decisive role in reproductive function. If the kidney essence function is abnormal, it will lead to abnormal sexual function and decreased reproductive function. ) and development (note: the growth and development law of the body is closely related to the rise and fall of kidney essence. When people are young, kidney essence gradually fills up, leading to physiological phenomena such as tooth lengthening. In young adults, the kidney essence is further filled, even reaching its peak, and the body also develops to a vigorous stage, with real teeth, strong body and strong bones and muscles. In old age, the kidney essence declines, the body gradually ages, the whole body is weak, and the teeth shake off, showing an aging image. It can be seen that kidney essence determines the growth and development of the body and is the basis of human growth and development. If the deficiency of kidney essence affects the growth and development of human body, there will be developmental disorders, such as stunting and skinny. Adults will get old before they get old. (Note: The kidney has the function of presiding over the whole body water-liquid metabolism and regulating the water-liquid balance in the body. Under normal circumstances, the metabolism of body fluid is realized by the gasification of kidney. Kidney maintains the balance of water and liquid metabolism in human body. If the kidney's gasification is abnormal, it will cause the disorder of water and liquid metabolism, which will lead to edema, oliguria or excessive urine. ), the main gas (note: it means to be solid and accept. Kidney governs the absorption of qi, which means that the kidney can absorb the clear qi inhaled by the lung and prevent the breathing from the outside to the inside, thus ensuring the normal exchange of gas inside and outside the body. ) and the main bone marrow (note: the essence in the kidney is an important part of promoting the growth and development of the body. The growth and development of bone depends on the filling of bone marrow and the nutrition it provides. Only when the kidney is full of essence can the bone marrow be nourished. The role of).
