The spleen is located in the abdomen, and its main physiological functions are to transport and transform, unify the blood, and dominate the muscles and limbs. The spleen opens the orifices in the mouth and the liquid is saliva. The meridians and veins of the spleen are connected to the stomach, and the stomach is in contact with it.
1, the spleen main transport transport, refers to transportation; chemical, that is, digestion, absorption. Spleen main transportation, mainly refers to its function of digestion, absorption, transportation of nutrients and water and moisture. The body's five organs, six bowels, limbs, muscles, skin and hair, are dependent on the spleen's transportation, in order to obtain nutrients, it is called the spleen as “the basis of the day after tomorrow”, “the mother of the five organs”.
The spleen's function of transportation mainly includes two aspects: one is the transportation of water and grain essence, i.e., the water and grain initially digested by the stomach is further digested and absorbed by the spleen, and the nutrients are transferred to the heart and lungs, and transported through the meridians to the surrounding body for the body's vital activities. This robust function of the spleen is called “healthy transportation”. Spleen qi healthy transport, its transport of water and grain function is strong, the whole body organs and tissues to get adequate nutrition, normal physiological activities. On the contrary, if the spleen is not healthy, the water and grain transportation function is not normal, there will be abdominal distension, diarrhea, mental fatigue, lethargy, malnutrition and other diseases. Secondly, it refers to the transportation of water and dampness, i.e. the spleen has the role of promoting the metabolism of water and liquid. Spleen in the transport of water and grain essence at the same time, but also the water transported to the tissues around the body to play its role in nourishing moistening, so the “Suwen - syncope theory” said: “the spleen main for the stomach line of its fluid also”. After metabolizing the water, it goes down to the kidneys and is discharged out of the body through the bladder. If the function of the spleen water-dampness dysfunction, there will be water-dampness stay a variety of pathologies, such as stay in the intestinal tract for diarrhea, stop in the abdominal cavity for ascites, overflow in the muscle surface for edema, water-dampness gathered into phlegm and so on. Therefore, “Suwen - to the true to the great theory” said: “all wet swelling, all belong to the spleen.”
Spleen will be the essence of water and grain and water and humidity up to the lungs, which is characterized by rising, so there is a “Spleen Lord rising clear” said. “Qing”, that is, refers to the essence of the nutrients. Also said “spleen qi main rise”. At the same time, the spleen qi has the role of lifting and maintaining the normal position of internal organs. If the spleen qi does not rise instead of sinking, in addition to lead to diarrhea, can also cause visceral prolapse symptoms, such as prolapse, uterine prolapse.
2. The Spleen is the main blood-unifying agent, with the meaning of unifying and controlling. Spleen main blood, means that the spleen has the function of regulating the normal operation of blood in the veins, not to overflow out of the veins. The difficult classic - forty-two difficult” said ‘spleen - ...... main blood warm five organs’, that is, refers to this function. Wrap the blood, that is, wrap, regulate the blood, do not make it overflow. The reason why the spleen can unify the blood, all rely on the spleen qi's role in the fixation. Spleen qi is strong, fixed right, the blood can run along the veins normally without overflowing; otherwise, the spleen qi is weak, lost its ability to regulate, the gas does not regulate the blood, will cause a variety of hemorrhagic disorders, especially chronic hemorrhage for the most common.
3. The spleen is the master of muscles and limbs, which means that the spleen can provide nutrients to the muscles and limbs to ensure that they are strong and function properly. The growth and development of muscles and their fullness and strength depend mainly on the spleen to transport the essence of water and grains to moisten and nourish them, so “Suwen - Impotence Theory” says: “The spleen is the master of the body's muscles”. Spleen qi healthy transportation, nutrition is sufficient, the muscle is full and powerful, otherwise the muscle is impotent and soft, the animal is thin, as the “yuan heng therapy horse set - fixed pulse song” said: “meat thin hair long wu xi (spleen) false”.
Functional activities of the limbs, but also rely on the nutrition delivered by the spleen to be able to play normally. When the spleen qi healthy, clear yang qi transmission cloth the whole body, nutrition is sufficient, the limbs activity is strong, walking light healthy; otherwise, the spleen is not healthy transportation, clear yang is not cloth, nutrients have no source, will lead to the limbs activity is weak, walking slow. Su Wen - yin and yang should be like the theory” said. “now the spleen disease, can not for the stomach line its fluid, the limbs are not endowed with water and grain gas, gas day to day in order to decline, the pulse is not favorable, sinews and bones and muscles, all have no gas to produce, so do not use it.” Animals suffering from a weak spleen and stomach, often limb impotence and weakness, tiredness and good lying is this reason.
4. opening in the mouth of the spleen, the main transport of water and grain, the mouth is the gateway to the intake of water and grain; and spleen qi through the mouth, and appetite has a direct link. Spleen qi exuberance, the appetite is normal, so the “spiritual center - the pulse of the chapter” said: “the spleen qi through the mouth, the spleen and can know the five grains carry on.” If the spleen is not healthy, the appetite of the animal will be reduced, or even abolished, so “Anji set - broken gold five viscera theory” said that “the spleen does not grind when the horse does not eat”.
The spleen is the main transportation, the mouth is the orifice of the spleen, the spleen and the meridians and lips are connected, the lips are the spleen's external should, so the mouth and lips can reflect the spleen's transportation function. If the spleen is healthy, nutrition is sufficient, the lips are bright and moist like peach blossom color; otherwise, if the spleen is not healthy, the spleen is weak, then loss of appetite, poor nutrition, pale lips; spleen has dampness and heat, then the lips are red and swollen; the spleen through the attack of heat and toxin, then the lips are sores.
