Kidney is the origin of the innate – “innate” refers to endowed with parents, “two gods wrestle” of the essence, and the innate essence of the innate gas, is inherited, for the origin of life, can also be understood as the male sperm and the female egg combined fertilization egg. It can also be interpreted as the fertilized egg that combines the male sperm with the female egg. “The kidneys store the essence and are the main source of vital fire, and vital fire is the source of vitality,” referring to the yang qi in the kidneys, which is the source of vitality. The essence of the kidney is overpowering, tiankui to, male essence easy to leak, female ren pulse through, taichong pulse is full of, through the following time, the two gods wrestle, so can have a child; after fertilization, the whole process of growth and development, and the ability to resist external evils, is the kidney’s essence of the fullness of the role of the decisive factor. Therefore, the kidney is the foundation of the innate. Spleen is the origin of the latter day, the source of qi and blood biochemistry – refers to the growth and development of the two essences and two gods wrestling in the mother’s body, as well as the nutritional supply of the body’s growth and development after birth, need the nutrients ingested by the spleen and stomach in the latter day to digest, absorb the essence of the water grains and valleys, transport and transform the water grains and valleys of water and dampness, and to promote the clearing of the turbid and the transformation of the role of the qi and blood, and therefore, a body, must be Diet into the stomach, the spleen and stomach together to generate qi and blood, the basis of the acquired. The theory of “the kidney is the foundation of the innate, the spleen is the foundation of the innate,” the kidney is the foundation of the innate, emphasizing the role of the kidney in human growth and development and reproductive function, mainly reflected as follows: 1, promote human reproductive function kidney essence is the original substance of human embryonic development, with the role of determining the reproductive capacity of the abundance and decline. After birth, kidney essence gradually full, the organs and tissues with the growth and development; to puberty, kidney essence full, the sky deca with to, the gonads with the development of maturity, and see the man spermatorrhea, women’s menstruation on time, the sexual function is mature, the ability to reproduce exuberant; people to the old age, the kidney essence is gradually loss, the sky deca gradual decrease in the sexual function and the ability to reduce the reproductive gradually. As stated in “Su Wen. Ancient Heavenly Truth” said: women …… two seven and the sky to seven, the Ren vein through, Taichong vein full, menstruation to the time under, so there are children; …… seven seven, the Ren vein is weak, Taichong vein decline, the sky to dry, the ground is not passable, so the shape of the bad and no children. Men …… two eight, the kidney qi is full, the sky deca to, the essence overflow diarrhea, yin and yang and, so can have a child; …… seven eight, the sky deca exhaustion, the essence is less, the kidneys are bad, the shape of the body are extreme.” 2, to promote human growth and development of the kidney in the essence of the kidney has a strong vitality, with the kidney in the essence of the by the abundance and decline of changes in the human body’s life activities show growth and strength of the old regularity of change. Such as “Su Wen. On the ancient theory of heavenly truth” said: “women seven years old, kidney gas, teeth more hair long; …… three seven, the average kidney gas, so the real teeth born and long pole; four seven, the tendons and bones firm, hair long pole, the body is full of strong; five seven, yangming vein decline, the face began to scorch, the hair began to fall; six seven, the three yang vein declined in the upper, the face is scorched, the hair began to white; seven seven, any vein virtual, tai chong pulse declined less, the Heavenly Decadence Failure ……. Men eight years old, the kidney gas is real, hair long teeth more; two eight, the kidney gas is full, the sky to the deca, the essence of the overflow diarrhea …… eight eight, then the teeth and hair to go.” Visible, the kidney gas is the driving force of growth and development, kidney gas is abundant, the growth and development of normal, teeth firm hair Ze, strong and powerful bones, normal viscera function; if the kidney gas deficiency, the growth and development of delayed, five soft five late, or teeth hair fall, premature aging, viscera dysfunction and other diseases. As Li Zhongzi said: “The baby was born, the first two kidneys. Not yet this body, first two kidneys, so the kidney for the viscera of this, the root of the twelve veins, the root of the whistle, the source of the triple jiao, and the human capital for the beginning of the people also. Therefore, it is said that the nature of the first in the kidney.” “The medical school must read. Medical theory of illustration”. 3, against external evil, prevent disease kidney essence not only can promote human growth and development and reproductive function, but also has to defend the body, prevent the role of evil invasion.” The true qi, received in the sky, and grain gas and filled the body also” “Ling Shu. Prick section of the true evil” said: the true gas, that is, the human body of the true essence of the gas. It is by the innate essence of the gas and nature of the gas and the combination of the essence of the water and grain, in which the kidney essence plays an important role. Therefore, the kidney essence is sufficient, is full of vitality, physical fitness, resistance to disease; if the kidney essence is insufficient, the true deficiency, physical weakness, easy to disease. Sun Simiao cloud: less essence is sick, exhaustion of essence is dead. Young and strong people, full of kidney essence, sufficient gas, so healthy and less sick; teenagers or the elderly, insufficient kidney essence, deficiency of kidney qi, weak power of evil, so weak and sick. The spleen is the foundation of the latter day, emphasizing the functional role of the spleen in the transportation of cereal and water 1, transportation of cereal is the spleen on the digestion and absorption of cereal, the transfer of nutrients to and from the cloth. After the preliminary digestion of grain and food by the stomach, it is sent down to the small intestine to continue digestion, and under the role of the small intestine in the urination and turbidity, the essence of it is absorbed by the spleen, and through the spleen’s dispersal of the essence of the role of the upward transmission in the heart and lungs, and dispersed throughout the body, in order to nourish the other internal organs and the body of the various ministries. The essence of the spleen is the material basis for the constitution of the human body and the maintenance of human life activities, such as the production of essence, gas, blood, fluid, etc. The transportation function of the spleen depends on the function of the spleen. The transportation function of the spleen depends on the spleen qi. Spleen qi healthy, the normal function of its transportation of water and grains, the essence of the material absorption is sufficient, the gas, blood, fluid biochemical source, the kidney in the essence of the continuous cultivation and replenishment of the body’s internal organs and tissues and organs to get adequate nutrition, so as to maintain its normal physiological activities. On the contrary, if the spleen’s function of transporting and transforming water, grain and essence is reduced, the body’s digestive and absorption function is also out of order, and bloating, loose stools, loss of appetite, or emaciation. Therefore, it is said that “the spleen is the foundation of the latter day, the source of qi and blood biochemistry”. 2, the transportation of water and drink, also known as “transportation of water and wetness”, is the spleen has the function of absorbing, transmitting and dispersing water and liquid, so as to maintain the balance of water and liquid metabolism in the organism. Water and drink enter the stomach, and after absorption, the fluid is transported by the spleen to the lungs and dispersed throughout the body. By the lung’s role in the dissemination of purging, internal to nourish the internal organs, external to moisturize the muscle coupling fur; its turbid, part of the sweat and excretion, part of the kidney down to the bladder; see the spleen in the body of water metabolism process plays an important role in the transfer and dissemination of the role of the spleen. Therefore, the spleen qi healthy, so that the body water can be normal circulation, not to accumulate, thus preventing wet, phlegm, drink and other pathological products. “The kidney is the foundation of the innate, the spleen is the foundation of the innate,” the relationship between the two 1, physiological: the innate and the innate mutual sustenance of the spleen’s transportation must be warmed by the kidney yang to be able to Jianhua; kidney essence and rely on the spleen to transport the essence of the grains and cereals of the constant supplementation to flourish. Therefore, the “medical door to drink” said “the spleen and stomach can biochemical, really by the kidney in the yuanyang of the encouragement, and the yuanyang to solid density for the expensive, so it can solid density, and rely on the spleen and stomach biochemical yin to nurture ear”; fully illustrates the innate warmth inspired by the innate, the innate complementary cultivation of the innate. In short, the spleen and stomach for the sea of water and grains, kidney for the sea of blood. “The beginning of man’s life is based on the original essence and blood, and the birth of man is based on the nourishment of water and grains. Non-essence and blood can not establish the foundation of the form, non-water grains, can not become the form of the strong.” “The sea of water and grain depends on the innate for the Lord, and the sea of blood and essence depends on the innate for the capital. Therefore, from birth to death, all the innate deficiencies, but the power of cultivation of the latter day, the work of making up for the sky, can also be in its strong half” “Jingyue quanquan. Spleen and Stomach Theory” 2, pathologically: spleen and kidney interact with each other, mutual cause and effect of kidney essence deficiency and spleen essence is not full, spleen qi weakness and kidney qi deficiency, spleen yang deficiency and the fate of the fire failure, spleen yin (stomach yin) lack of yin and kidney yin decline, often interact with each other, mutual cause and effect. Such as kidney yang insufficiency, can not warm spleen yang, spleen yang or spleen yang is not vibrant or spleen yang for a long time, and then damage to the kidney yang, caused by kidney yang is also weak, the two ultimately lead to the spleen and kidney yang deficiency; mostly manifested as cold and abdominal pain, lumbar lacquer soreness and weakness, diarrhea, finished grain is not chemical, etc.; insufficient renal essence, can not warm and nourish the spleen essence, spleen essence is not full, and then the spleen and kidney essence is weak; the clinical manifestations of growth and development is retarded or aging before the age of old age. Because of the theory of “kidney is the innate” and “spleen is the innate”, the dialectic treatment of spleen and kidney essence deficiency or spleen and kidney yin and yang deficiency is “tonifying the kidney is not as good as tonifying the spleen” and “tonifying the spleen is not as good as tonifying the spleen” and “tonifying the spleen is not as good as tonifying the spleen” and “tonifying the spleen is not as good as tonifying the spleen”. Therefore, the dialectic treatment of the deficiency of essence of the spleen and kidney or the deficiency of yin and yang of the spleen and kidney has the academic dispute of “tonifying the spleen is not like tonifying the spleen” and “tonifying the spleen is not like tonifying the kidney”. To a certain extent, the latter plays a decisive role in the health of the human body, but the innate is also an important factor, should be based on the patient to distinguish between the lesser and the greater importance, which is first and which is later, or warm tonic kidney yang, and tonic spleen yang, or warm tonic spleen yang, and tonic kidney yang. In conclusion, the spleen and kidney, physiologically, support and promote each other successively; pathologically, they influence each other and are the cause and effect of each other; therapeutically, the overall concept of the spleen and kidney is to differentiate which is the less important, which is the first and which is the last, and the dialectical treatment.
