The rise and fall of food refers to the directional function of medicine and food, that is, the four trends of medicine and food in human body: ascending, descending, dispersing and diarrhea. In clinical application, diseases are located on the surface, such as headache, chills, fever, etc., when floating drugs are used; If the disease is located in the lower stomach or upper stomach, such as constipation, dysuria or nausea and vomiting, sedimentation drugs can be used; If the condition shows a downward trend, such as persistent diarrhea, proctoptosis, uterine prolapse, etc., floating drugs are needed. Under normal circumstances, the functional activities of the human body have ups and downs, ups and downs. The imbalance between ascending and descending, floating and sinking will cause pathological changes in the body. If the spleen-qi should rise but not rise, the turbid qi will fall, which is manifested as concave diseases such as proctoptosis and uterine prolapse; When the stomach qi drops, it can be manifested as vomiting, hiccups and other qi-adverse diseases. Using the characteristics of food itself can correct the imbalance of body ups and downs.
Generally speaking, the rise and fall of food is closely related to the smell and taste of food, that is, the smell of food and its yin and yang attributes determine the direction of food action. As long as it is warm, spicy, light and healthy, its functions tend to rise and fall, such as ginger, garlic, pepper, peach, cherry, long pepper and cinnamon. As long as it is cold, sour, bitter and salty, its function tends to precipitate, such as almond, plum, lotus seed, wax gourd, mung bean, pear, Malantou, eggplant, loofah, cucumber, water bamboo and so on. Among the commonly used foods, there are more foods that tend to sink than those that tend to float.
