The phrase “Prana Gate” means the anus, and “Prana Gate is also the envoy of the five viscera” is from the “Suwen – Five Viscera Special Treatise” of the Huangdi Neijing: “Prana Gate is also the envoy of the five viscera, and water and grain cannot be hidden for a long time”, which This statement summarizes the relationship between the prana (anus) and the internal organs. The opening and closing of the prana (anus) depends on the regulation of the qi of the five viscera, and “the prana is also the messenger of the five viscera”, which means in a nutshell that the opening and closing of the anus depends on the mastery of the mind, the regulation of the liver qi, the elevation of the spleen qi, the promotion and lowering of the lung qi, and the consolidation of the kidney qi. Today we will talk about the relationship between the opening and closing of the anus and the five organs. The reason why the anus is the “prana gate” is mainly based on two principles: 1, “prana” through the “meal”, the anus is the gateway for dregs out of the body, so named “Prana (meal) door”. 2, according to the basic theory of Chinese medicine, the lungs hide the prana, the lungs and the large intestine, and the anus is connected to the large intestine, so it can be called “prana door”. The relationship between the prana gate and the five organs 1, heart “heart, the sovereign’s official, the gods out of it”, the heart is the master of the gods, the heart is normal, then the prana gate open and close in an orderly manner, defecation is sometimes in order. If the heart and mind are not clear, as in the case of stroke in Chinese medicine, the wind and fire, phlegm and heat close the heart orifices, and the heart and mind are not nourished, then the patient appears to be suddenly faint, unconscious, with strong spasms in the limbs, and the stool is closed and not accessible, and other closed manifestations. If the positive does not overcome the evil and the vital energy is weakened, the patient will suddenly faint and fall down, the limbs will become limp, and the bowels and stools will be lost. In addition, if the function of the prana gate is abnormal, it will also react on the heart, for example, if the diarrhea is prolonged and the heart and mind are depleted, it is possible to have fatigue and palpitations. Another example is prolonged constipation, the internal Qi is not blocked, the heart and mind will easily appear restless, irritable insomnia and other symptoms. There are some people, in the case of emotional tension, stress will appear constipation or diarrhea, can also be explained by this theory. The lungs are the lungs, the main gas, the division of the whistle, the main propagation and surrender, and can also regulate the water channel, and through the meridians and the large intestine, the large intestine and the conduction of gasification and prana door to open and close the defecation, depending on the lung qi propulsion and propagation role. The lung is sufficient, coordinated with the promotion and descent of the lung qi, the qi is smooth, then the stool is smooth. In addition, the lung is the source of water, and yin is injected into the large intestine, so the stool will not be dry. In a pathological state, deficiency of lung qi, weakness in suction and descent, and slow conduction of the large intestine will lead to constipation; malfunction of the lung in regulating the water channels, and inability of the fluid to be injected down into the large intestine will also lead to constipation. Similarly, the abnormal function of the prana gate will also have a counter effect on the lung, such as stagnation in the large intestine, the internal Qi does not pass, and the turbid Qi attacks the lung, which can lead to cough and asthma. Clinically, there are many elderly people with constipation: the stool is not necessarily dry, but squatting is very laborious, sweating, shortness of breath, it may be due to deficiency of lung qi. The spleen and the stomach are the foundation of the latter, the spleen is the master of clearing, the stomach is the master of lowering turbidity, the spleen is the master of transporting, the stomach is the master of receiving, the spleen and the stomach can turn food and water into water and grain, and spread the essence throughout the body, and make the small intestine transfer the food residue to the large intestine, and the large intestine transfer the dregs to be discharged from the prana gate. The conduction function of large intestine depends on the nourishment of qi and blood and the nourishment of fluids. Therefore, the opening and closing function of the prana gate depends on the lifting and lifting of spleen qi and the circulation and lowering of stomach qi. If the function of spleen and stomach is normal, the conduction of large intestine and the opening and closing of prana gate will be normal; if the function of spleen and stomach is abnormal, the conduction of large intestine will be abnormal, resulting in abnormal opening and closing of prana gate, as stated in Su Wen – Yin Yang Ying Xiang Da Lun, “If the clear qi is below, food and diarrhea will be produced, and if the turbid qi is above, anger and distension will be produced. abdominal distension, diarrhea, constipation and other symptoms, if fatigue injury to the spleen, the spleen does not rise to clear, then the food and diarrhea loose; if the diet hurts the stomach, the stomach and loss of descending, then see angrily distended constipation. In addition, if the spleen is not enough, the middle qi trapped, will also lead to prolapse. 4, the liver is the master of draining, can regulate the qi, promote the lift of the qi in and out, regulate the conduction of the large intestine and the opening of the pranic door. If the liver qi is regulated, the qi will be regulated smoothly, and the large intestine conduction and the opening and closing of the pranic door will be normal. If the liver is not drained, the spleen will be affected and the conduction of the large intestine will be affected, resulting in loose stools; if the liver qi is depressed, the qi will be stagnant and the conduction of the large intestine will be weak, resulting in constipation. Therefore, Li Cheng pointed out in “Introduction to Medicine” that “the liver is connected to the large intestine, liver disease should be unblocked large intestine, large intestine disease should be pacified liver”. 5, kidney The kidney is open to the second yin, the main division of the two stools. The rear yin is the prana, and the relationship with the kidney is very close. The kidney’s Yang plays a role in promoting and warming the internal organs of the body, and the conduction function of the large intestine depends on the warming and tempering of the kidney Yang and the nourishment and moistening of the kidney Yin, and the opening of the prana door also depends on the role of the kidney Qi. In Jing Yue Quan Shu – Diarrhea, it is said that “the kidney is the stomach off and opens the orifice in the second yin, so the opening and closing of the second stool are dominated by the kidney”. In pathological cases, if the kidney yang is deficient or the kidney qi is not enough, then there is no power to fix and the diarrhea is easy to occur; if the spleen yang is deficient and the kidney yang is not enough, then the water and grain will be mixed and become diarrhea, and it is mostly before dawn, so it is called “five-shift diarrhea” or “rooster diarrhea”.
