Chinese medicine believes that the blood is mainly composed of Ying Qi and fluid, Ying Qi and fluid, are from the ingested diet, through the spleen and stomach digestion and absorption to generate water and grain essence, so that the spleen and stomach is the source of qi and blood biochemistry. Spiritual Pivot, evil guest” in the discussion of the function of the Yingqi generated blood, said: “Yingqi, its fluid, injection in the veins, into the blood; to the Wing four end, the injection of the five viscera and six bowels …… “. Essence hidden in the kidneys, blood hidden in the liver, the kidneys are full of essence, then the liver has to support, learn to be full; liver blood is full of, then the kidneys have to hide, the essence of nourishment. Blood operation depends on the gas to promote and regulate the role of blood operation depends on the heart beat, “Su Wen, impotence theory” cloud: “the heart of the body’s blood”, “the introduction to medicine,” said: “the heart of the people move, then the blood line all the meridians”. Difficulties in the scripture, twenty-two difficult” said: “gas main warm, blood main moistening” summarizes the difference between the gas and blood function, but also “gas for the blood of the commander, blood for the gas of the mother” of the close relationship between the gas can be born blood, blood intake, blood, blood can be the mother of the gas. 1, blood and the relationship between the five organs: Ming Dynasty Zhang Jingyue’s “Jingyue Encyclopedia” cloud: “blood of the essence of water and grains, the source, and the real biochemical in the spleen, the President of the heart, the hidden acceptance of the liver, announced in the lungs, the Shi leakage in the kidneys and irrigate a body”. This means that blood has a close relationship with the five organs. The relationship between blood and the spleen and stomach: “the spirit of the center, decided to gas” in the cloud: “the middle jiao by the gas to take juice, change and red, is called blood.” Pointed out that blood is a red liquid, its generation is mainly in the middle jiao spleen and stomach biochemical function, its blood raw materials mainly from the diet of the essence of the material, the essence of the heart, change and red, the formation of blood. It also recognizes the importance of the spleen and stomach in the formation of blood in the middle jiao, and that if the spleen and stomach are dysfunctional, the generation of blood can be affected. The importance of the spleen and stomach can be seen from the fact that “if you have stomach qi, you will live; if you do not have stomach qi, you will die”. The relationship between blood and kidneys: “the spiritual center, meridians and veins”: “people are born, the first into the essence, essence into the medulla oblongata, bone for the trunk, the veins for the camp, …… blood is line”, blood for the nutrition of the whole body of the material, the cycle of running in the veins and channels, in order to serve to nourish the whole body, the blood into the beginning of the essence, “the spiritual center, Ben Shen” cloud. The Spiritual Pivot / this God” cloud: “the kidneys hide the essence”, “Su Wen / five runs in the Great Theory” and said: “the kidneys are born bone marrow”. Suwen Xuanming Zhengqi” says: “The kidney is the main bone”, and “Suwen Ani Tongtian Lun” says: “The bone marrow is strong, and the qi and blood all come from it”, reflecting that the hematopoietic role of the marrow in generating blood is mainly dependent on the functional state of the kidneys. The relationship between the blood and the heart: the blood runs in the heart chakra, “Su Wen, Six Sections of Hidden Elephant Theory”: “The heart, the basis of life. God’s change is also, its Hua in the face, its full in the blood”; “Spiritual Pivot, this collection”, “the meridians, so the line of blood and yin and yang, moistening the muscles and bones, and joints, also”; “Su Wen, the regulation of menstruation,” “the way of the five organs are out of the meridians and tunnels, in order to line the blood and qi! “. The meridians and tunnels refer to the tunnels through which the blood runs, i.e. the blood veins. It indicates that the transportation function of blood is linked to cardiovascular function. The abundance or otherwise of blood in the heart is related to the health of the person, such as “the heart is the master of the blood, and its splendor is in the face”, when the heart is full of blood, the face is red and glossy, and when the heart is insufficient, the face is pale and colorless. The relationship between blood and liver: liver in the motherland medicine is both a blood organ, but also a blood organ, “Suwen six sections of the Tibetan elephant theory” said: “the liver, …… to angry blood.”, “Ling Shu Ben Shen”, “the heart of the blood”. The “Spiritual Pivot・Ben Shen” chapter contains: “The liver hides blood. Regarding the blood supply, blood distribution and regulation of the functions of organs and tissues throughout the body and the relationship between the liver, “Su Wen・Wu Zang Generation Chapter” says: “Therefore, people lie down and blood returns to the liver.” Wang Bing commented, “The liver stores blood, and the heart carries it out; when a person moves, blood returns to the meridians, and when a person is still, it returns to the liver.” This indicates that the liver has the function of storing blood and plays a role in regulating the volume and distribution of blood throughout the body. At rest, part of the blood is stored in the liver, and when active, the blood in the liver is mobilized and transported throughout the body to supply the organs and tissues. When the liver’s blood storage function is impaired, both the regulation of blood volume and bleeding can occur. Therefore, the physiological activities of all parts of the human body are closely related to the liver, so it is said: “The liver receives blood and can see, the foot receives blood and can walk; the palm receives blood and can hold, the finger receives blood and can take.” Zhang’s Medical Guide is the cloud: “gas is not consumed, the essence of the kidneys and for the essence, essence is not excreted, the essence of the liver and clear blood.” In modern medicine, the liver is the largest blood-holding organ in the human body, and the blood-forming activity of the liver is seen in the embryo from 2 to 5 months. The relationship between blood and the lungs: Chinese medicine believes that the lungs are responsible for all the qi in the body, directing all the veins and governing the joints, and that the blood in the whole body passes through the meridians and gathers in the lungs, where it breathes, exchanges gases, and then transports them throughout the body. The Spiritual Pivot・Ying health will be the chapter” cloud: “the middle jiao also and the stomach …… urinate dross, steam essence, the essence of its micro, injected into the lung veins, is transformed into blood, in order to serve the birth of the body, no one is more valuable than this, so only get to line the meridians and tunnels.” This emphasizes the important role of the lungs in the production of blood. Yi Yi Li of Medical Science says: “The heart releases the turbid qi of purple blood and shrinks into the clear qi of red blood. Red blood that is subject to the lungs to suck people clear gas angry, by the heart to run blood vessels, nourishing the essence of the body also. Purple blood that is subject to viscera meridian turbid gas, poisonous changes in the blood, from back to the blood vessels to run the lungs, to be exhaled turbid gas, to get sucked into the clear gas, then the purple blood to change into red blood, still flow around the body. To nourish life.” Here, the lungs of the respiratory gas, spit out the old and new, the Division of turbid and clear exchange, “purple blood” edge of the lungs to a steady stream of “red blood”, and modern medical theory. 2, the relationship between blood and gas: “Su wen, heat theory” has: “camp and guard can not, the five organs can not.” See the camp blood and the importance of Wei Qi. Gas and blood have a close relationship, gas is yang, blood is yin, “yin is the base of yang, yang is the unity of yin”, “yang is long yin”. It can be seen that the generation of blood depends on gas, gas can promote blood. Gong Tingxian of the Ming Dynasty, “Shou Shi Bao Yuan, blood and gas,” said: “the blood of the blood of the marshal, gas line is blood line, gas stops the blood stops, the temperature of the blood is slippery, the gas is cold blood coagulation, the gas is not transported in a breath, then the blood has a breath of no. “. Blood is an important part of the body’s vitality, “the evil, its gas must be weak”, “the righteousness within, the evil can not be dry”, visible gas and blood of the fullness of the relationship between the resistance to the strength of the weak. In short, the blood and the body’s function, health, resistance, life expectancy are closely related. 3, the function of the blood: thousands of years ago, the motherland medicine on the function of the blood has a deep understanding of the “Suwen pulse to the essence of the theory” cloud: “the pulse, the blood of the House also.” Recognize the function of filling the blood; with the gradual development, recognized that the blood can circulate moistening, nutrition, the whole body, “Jade machine micro-righteousness” in the cloud: “Dirty and can liquid, viscera and can gas, in and out of lifting moistening XuanTong, and not from this.” This means that blood can maintain the vital activities of the body’s internal organs, body, nine orifices and other tissues and organs. Jingyue Encyclopedia” said: “Where the shape of the quality of the place, no non-blood use, is that people have this shape, but rely on this blood, so the blood decline form atrophy, blood defeat is bad. And all the skeleton of the genus of the table, where the blood loss, it will be with the location, and each born of its biased disease.” This means that the blood has a role in protecting against evil, which is realized through the role of moistening and nourishing. For example, “the doctor must read the medical theory charts say ancient and modern yuan qi different theory” cloud: “gas and blood, people rely on the birth of a person, gas and blood is full of all the evil outside the defense, the disease an from? The deficiency of qi and blood, then all the evils converge, all the disease collection.” Please source of disease theory, “the Houzhu, the wind and labor Houzhu,” also said: “blood and gas weak, the skin and coupling of the thin, easy to invade the wind, or easy to swim in the skin, or stagnant viscera, with its senses, and the disease is born.” Also proposed that the blood has the function of defense against external evil. As for the blood transportation function and mental thinking activities, the relationship between the external environment, “the spiritual center, the Tibetan” chapter: “the will; so the Royal Spirit; collection of the soul, the appropriate cold and temperature, and joy and anger. It is the blood and the meridians and popular …… “, indicating the regulation of the internal and external environment, the need for blood harmonization and smooth, blood has a “Royal Spirit”, “collect the soul and spirit The blood has the ability to “control the spirit”, “collect the soul” and “adapt to cold and temperature”.
