Before Li Shizhen, many health practitioners have studied drinking water, and generally believe that: the sky is one, the earth is two, water born in the sky, valley into the earth, the innate nature of man is just a drop of water, so to water and grain food as the main, to dishes with. Li Shizhen (1518~1593), the word Dongbi, the number near the lake mountain people, the Ming Dynasty herb. 14 years old in the examination, but since then a series of three failed imperial examinations. So he gave up the idea of “the road to the imperial examinations and eunuchs” and abandoned Confucianism to study medicine. In the “Compendium of Materia Medica”, he clearly put forward: “Food, the lifeblood of man, and the camping and health rely on it. Therefore, it is said: water goes to the camp is exhausted, and the grain goes to the health death.” He believes that a person’s health and longevity depends first and foremost on a reasonable diet structure and diet methods. Water: smooth flowing water is the best Before Li Shizhen, many health practitioners have studied drinking water, and generally believe that: the sky is one, the earth is two, water born in the sky, valley into the earth, the innate human is just a drop of water, so to water and valley food is the main, to dishes with the. Water and grain, water nourishes Yang and grain nourishes Yin, so water is the most important. The book “Guanzi” also said: “water, the blood of the earth, such as the circulation of the tendons and veins”, and water for “water”, “branch water”, “valley water “, “river water” and “abyssal water”. Southern Song scholar Jia Ming in his “diet instructions”, and a variety of heavenly rainfall water has been defined. Such as “sky rainwater, taste sweet and light, cold nature”, “dew water, taste sweet, cool nature”, “ice, taste sweet, nature cold”, and “hail water, taste salty, cold nature, poisonous” and so on. cold nature, poisonous” and so on. Li Shizhen is of the view that: “water is the image of Kan, up for the rain and dew, frost and snow, down for the sea and river springs and wells”; flowing water, “its external movement and quiet nature, its quality of soft and rigid gas”; “water is salty and heavy, the labor is sweet and light. Take it does not help the kidney, but also benefit the spleen and stomach.” He also classified the river and lake water as “ground water” and divided it into “flowing water”, “counter-current water” and “fast flowing water “three kinds. Among them, “smooth flowing water” is smooth and downstream, also known as Ganlan water; “counter-current water” is migratory water, the nature of the reverse and reverse up; “rapid flow of water” because of the turbulence on the water is steep and rapid, its nature is rapid and down. Therefore, he said that “Tianshui is one” and “Dishui is two”, thinking that “Dishui” is not as good as “Tianshui”; and The “earth water” in the river and lake water, and “Shun Liu Shui” as a good drink. Food supplement: duck meat for deficiency, mutton for shape About food supplement and food therapy, Li Shizhen discusses a lot. For example, bean sprouts “sweet and warm, non-toxic”, can cure “damp paralysis and knee pain, deficiencies in the five organs, spleen and stomach gas stagnation. Strength, moisten the skin, benefit color, fill the bone marrow, replenish the deficiency”; carrot, “sweet, pungent, slightly warm, non-toxic”, can be treated “down the gas and tonic, the chest and diaphragm intestines and stomach, the five organs, people healthy food. Duck meat in poultry, “the main tonic deficiency labor, the most clear poisonous heat, urine, edema, fullness”; if the duck meat with glutinous rice porridge to eat, with nourishing stomach, blood, the role of the body, after the disease, a great benefit; Wu chicken “sweet, slightly warm, non-toxic”, can treat “belly pain, heart and abdomen bad gas, in addition to rheumatism and palsy, and to calm the fetus.” And attached to the formula “tonic for weakness: weak people with a wu xiong chicken treatment clean, five flavors boiled very rotten, empty stomach diet of”, “or five flavors pickled moxibustion food. Among domestic animals, mutton is a great tonic. Li Shizhen said that it can be compared with ginseng and astragalus; “astragalus replenishes gas, while mutton replenishes form”. When eating mutton, the stomach to leave room, do not eat too much, full will hurt the spleen bad belly. About the nutrition of fish and eating, Li Shizhen also has many arguments. Such as carp “sweet, flat, non-toxic”, if cooked, can cure “cough rebellious upper gas, jaundice, thirst.” Raw, it can treat “edema and fullness of the feet, down the gas. Treatment of pregnancy body swelling, and fetal gas restlessness.” Porridge: the elderly eat japonica rice porridge Li Shizhen advocates the elderly eat porridge. He believes that: the elderly have more damaged teeth, the spleen and stomach function is weak, the implementation of the best porridge nourishment. “Every day, eat a large bowl of porridge, empty stomach deficiency, grain gas will be made, the complement is not fine, and very soft and greasy, and the stomach and intestines get, the most wonderful trick of diet.” The best raw material for making congee is japonica rice, because it is sweet and flat, and is a good medicine for strengthening the spleen and stomach and cultivating the middle energy. In the “Compendium of Materia Medica”, Li Shizhen also wrote about the preparation and serving of carrot porridge: fresh carrot, diced, cooked with japonica rice porridge, taken every morning and evening. Carrot sweet pungent slightly warm, if often eaten, modern research seems to prevent hypertension and enhance the physical fitness of the elderly. As for drinking wine, Li Shizhen wrote this in his “Compendium of Materia Medica”: “Wine, the beauty of the sky Lu also. Drinking less is to live the blood and move the gas, strong gods, cold, and dispel sorrow. Drinking painfully will hurt the spirit of blood, damage the stomach and lose essence, phlegm and fire”. “If you indulge in excessive drunkenness, drunkenness to the unconventional, the lighter to cause disease and defeat, and even the loss of state and family, and fall body life. The harm is too much to say!” Also said: “over-drinking without restraint, kill instantly …… good regimen should be quit.” In addition, Li Shizhen stressed not to drink tea after drinking. He wrote: “drinking tea after drinking hurt the kidneys, waist and feet fall heavy, bladder and epigastric cold disease, and suffer from phlegm drink edema, thirst contracture pain of disease.” If you look at the doctrine of yin and yang in Chinese medicine, drinking wine will rise and spread, promote blood circulation; and tea bitter, Yin, the main drop. If you drink tea after drinking, will drive the alcoholic in the kidney. And the kidney is the main water, water wet, thus forming a cold stagnation; cold stagnation leads to frequent turbid urine, stool knot dry. Therefore, after drinking tea should not drink, but should eat some fruit.
