The efficacy and contraindications of leek
|
[Aliases of leeks] Yellow chives, white chives, longevity chives, yang-raising vegetables, flat vegetables, and aphrodisiac vegetables. 【annotation】 Leek is one of the traditional vegetables in China. There are records about leeks in "Classic of Mountains and Seas". Leeks were planted in greenhouses in the Han Dynasty, and there are records of leek cultivation in the Northern Song Dynasty. Leeks are said to be "fragrant in spring, spicy in summer, bitter in autumn, and sweet in winter", and spring leeks are the best. Chives are a softened variety of leek. When green leeks are shaded, chlorophyll disintegrates, and free amino acids such as glycine accumulate to form lutein, which will turn yellow. Chives are not only bright in color, but also taste better than leeks, but their nutritional value is far less than that of leeks. 【Nutritional ingredients】 Leek is rich in protein, fat, carbohydrate, calcium, phosphorus, iron, vitamin A, vitamin B1, vitamin B2, vitamin C and dietary fiber, etc. Except for selenium, the content of other nutrients in leek is higher than that in leek. 【Medicinal properties and effects】 Leek is warm in nature and can dispel cold and disperse blood stasis, nourish yin and strengthen yang. It has auxiliary therapeutic effects on male enuresis, impotence, spermatorrhea, premature ejaculation, and lower abdominal cold pain during menstruation and postpartum milk stagnation in women. The large amount of vitamins and minerals it contains can assist in the treatment of night blindness, dry eyes, rough skin and constipation. It also has the effect of preventing cancer recurrence, reducing the intestinal absorption of oily substances and losing weight. 【Eatable】 It is suitable for men, women, old and young. When eating, leeks (leek) can be used as the main ingredient, as a side ingredient, or as the filling of dumplings and spring rolls. People with weak constitution, rough skin, constipation, hemorrhoids and intestinal cancer should eat more, 50 grams each time. It is suitable for people with night blindness and dry eye disease, because the large amount of provitamin A contained in leeks can maintain the normal function of rhodopsin. 【Avoid eating】 People with yin deficiency but excessive internal fire, weak gastrointestinal tract but heat in the body, ulcers, and eye diseases should eat it with caution; do not eat fried leeks overnight; do not eat too much in summer; do not eat it with honey or beef. 【References】 "Food and Medicine" states: "Cooked and eaten, it can strengthen the kidneys, stop spermatorrhea, and warm the knees and waist." "Compendium of Materia Medica" says: "If you eat it for sores, the pain and itching will increase. If you eat it for boils, it will make the condition worse." "Compendium of Materia Medica" states: "Do not take if the stomach qi is weak and there is heat." "Compendium of Materia Medica" says: "Taking this medicine can promote blood circulation and disperse qi, strengthen the liver and kidney, and how can the disease not be cured?" "It is most taboo to use it when the fire is strong and the yin is weak." "Suiyuan Food List": "Specially pick the white part of the leek and stir-fry it with dried shrimps, or use fresh shrimps, clams, or meat. Peel the clam meat and stir-fry it with leek." "Sui Xi Ju Diet" states: "It is forbidden to eat after suffering from malaria, boils, and smallpox." |
