The natural world has its own laws of change, namely the four seasons, the 24 solar terms, day and night, and the changes of the sun and moon. The changes of yin and yang in the four seasons are the fundamental factors for the occurrence, growth, development, aging and death of all things in nature. The human body also has its own law of growth and change, i.e. the rhythm of 7 and 8, which is a cycle of 7 years for women, and at the age of 49, they will move from middle age to old age. Men have a cycle of 8 years, and at the age of 64, they move from middle age to old age. This natural rhythm of human biological rhythm is coordinated, if it does not correspond to the four seasons and violates the law of yin and yang changes, abnormal disasters will occur, and human beings will suffer from diseases; only by conforming to the changes of yin and yang of the four seasons, so that one’s spiritual activities, living and resting, diet and taste, and working hours are coordinated with the law of yin and yang changes of the four seasons, can one achieve a long and healthy life. Chinese medicine believes that “medicine and food are in harmony”, and the rational use of different flavors and diets can help the body maintain the coordination of yin and yang, internal organs, qi and blood. In Su Wen? The viewpoint of “five grains for nourishment, five fruits for help, five animals for benefit, five dishes for enrichment, the combination of odors and served to replenish the essence” is the characteristic and advantage of Chinese medicine food therapy and nutrition. However, it especially emphasizes the view that “hyperactivity is harmful”, that is, it should be appropriate and not too much, too much is harmful. In the book “The Book of Health”, it is said that there are “six appropriate” ways to maintain health: early food, warm food, less food, light food, slow food, and soft food. The “eight papers of Zun Sheng” have: thick taste hurts no one knows, can be willing to light is my teacher, three thousand gongxiang from the beginning, the sky is the letter of the line collection. So the correct use of food therapy, cure the end of the disease health care has a guiding significance. Using the above theory to guide the four seasons of Chinese medicine health food therapy, applied to clinical, received good results, but also popular with patients. 1, spring health rules: regulate the liver and spleen Herbal tea: Buddha’s hand, citron, rose flower, jujube seeds, jujube skin, infusion of water as a tea drink Herbal food: coix seeds, yam, lotus rice, gravy, lentils, stew before and after Qingming 2, summer health rules: clear the heart and nourish the yin Herbal tea: maidenhair, raw earth, light bamboo leaf, western ginseng, infusion of water as a tea drink Herbal food: lotus leaf, boiled rice 3, autumn health: moisten the lungs and spleen Herbal tea: ginseng leaves, dendrobium, maidenhair, infusion of water as a tea drink Herbal food: Chuan Ming ginseng, north sage, yam lotus rice, gorgonians, lentils, barley, yucca, yellow essence, figs, Manchurian fruit, stewed around mid-autumn, steamed duck pear, raw groundnut 30g, cooked groundnut 30g, lily of the valley 30g, stewed duck 4, winter health: warming the kidneys to help Yang Herbal tea: red ginseng beard, wolfberry, infusion of water as a tea drink Herbal food: astragalus, angelica, eucommia, wolfberry, barley, ginger, stewed lamb around the winter solstice, pork loin, eucommia, ripe groundnut, mulberry seeds, bone marrow, cuscuta, black rice, walnuts, black sesame, Shou Wu, mushroom Ganoderma lucidum, cardamom Black beans cooked in medicinal juice, eat black beans after boiling dry Chinese medicine “treats the last disease”, using different food therapy methods in all seasons to adjust the body in a healthy state, with the characteristics and advantages of Eastern culture. People are closely connected with the heaven and earth, the sky has sun and moon, people have yin and yang; the sky has spring and summer, long summer, autumn and winter, the earth has five elements of wood, fire, earth, gold and water, and people have five organs of liver, heart, spleen, lungs and kidneys. Such a close correspondence determines that the internal environment of the human body must be consistent with the external environment of nature, i.e., nourishing the liver in spring for the birth of spring, the heart in summer for the growth of summer, the spleen in long summer for the transformation of long summer, the lung in autumn for the harvest of autumn, and the kidney in winter for the hiding of winter; nourishing the yang in spring and summer and the yin in autumn and winter throughout the year to adapt to the change of the qi of heaven and earth.
