Every year, the spring season starts again, and the word “spring” is used as a starting point to officially announce the end of the long winter, and in its place, a spring season in which all things are revitalized and the yang qi flourishes. The five organs in the human body and the four seasons, in terms of health science have their own focus. According to Chinese medicine, the main point of spring health care is to comply with the natural law of spring yang qi, all things are sprouting, and take care of the yang qi in their own bodies. Spring is “wood”, wood has the characteristics of growth, and one of the five organs of the human body, liver is also wood, the liver began to flourish in the spring, take advantage of the situation to maintain the liver can be avoided during the summer of yin deficiency, is the best time to protect the liver. What does it mean to “grow and develop”? We know that woody plants grow by extending their branches in all directions, especially outward and upward, and their internal nutrients are also transported upward from the roots to the branches. The liver is also characterized by its wood nature, and it is the “master of detachment and excretion, and it hates depression and likes to regulate it”. However, if the function of detachment and excretion is over-exuberant, and “liver fire” spreads upward and outward along the meridians of the liver, then it will cause liver fire and hyperactivity of liver yang, and other disorders. The significance of liver protection in the beginning of spring is to try to harmonize the detachment of liver qi with the rising of spring yang, in order to enhance the body’s ability to adapt to the outside world, and smooth transition of seasonal changes. The main points of liver protection are: First, after the spring of hepatitis A, hepatitis E prevalence rate increased significantly, the beginning of spring liver injury, more attention to the prevention of infectious diseases and festivals during the diet; Second, to ensure adequate sleep, it is best to take a siesta, because “people lie down to the blood to the liver”; Third, the force to avoid anger, avoid melancholy; Fourth, it is advisable to eat sweet and spicy dispersal of products, should not eat more of the liver!
