In Chinese medicine, the left ascending and right descending of the spleen and stomach refers to the coordination between the spleen’s main function of ascending and clearing and the stomach’s main function of harmonizing and descending, in order to regulate the qi of the whole body. The spleen is responsible for transportation (the spleen has the function of digesting food, absorbing food essence and water and transferring it to the whole body), ascending and clearing, transferring the essence of water and grains up to the heart, lungs, head and eyes, and nourishing the whole body through the role of the heart and lungs in the production of qi and blood. The stomach is the main receptor (acceptance of accommodation), will be putrefied (preliminary digestion of food, the formation of food waste) of the water and grains downward transmission in the small intestine, through the small intestine of the separation of clear urinary turbidity, the dregs will be transported to the large intestine and ultimately discharged from the body. If the spleen rises and the stomach descends in dysfunction, then the qi will be inverted, and the water and dampness will stop and gather, and there will be vomiting, belching (hiccups), eructation (hiccups), etc., and the symptoms of the spleen’s failure to raise and clear, such as the upward reversal of stomach qi (stomach qi rises instead of descending) and epigastric distension and stuffiness (the abdomen feels uncomfortable with flatulence), poor appetite (bad appetite), and bowel movement disorders.
