Stomach qi is the basis” is the way to get the effect. “Stomach qi is the basis” is from “Su Wen – Ping Ren Weather Theory”. It is also said in “The Five Flavors” that “all five viscera and six internal organs are endowed with qi in the stomach”. Physiologically speaking, stomach qi represents the body’s digestion and absorption function and is a sign of the body’s ability to resist disease. Pathologically speaking, “with gastric energy is life, without gastric energy is death”. Therefore, the protection of stomach qi is the first thing to prevent and cure diseases. To maintain health and cure diseases, we must first pay attention to “stomach qi”, that is, to open the stomach and receive grain in the first place. Poor appetite, also known as “nadir” in Chinese medicine, can cause two consequences: one is to affect the digestion and absorption, reducing the ability to resist disease; the second is the right evidence of the soup, due to nadir affect the absorption will also reduce the effectiveness of the medicine. Therefore, it is important to ask the patient’s appetite before administering the medicine.
