day lily

"There is no treasure jade in the farmhouse, and the yellow flowers everywhere are real gold." This is the true praise of the predecessors for the day lily. Day lily, the scientific name of day lily, is a Liliaceae plant, which has been cultivated in China for more than 2000 years. Its leaves, roots, stems and flowers can be used as medicine. It tastes sweet and flat, and has the effects of nourishing blood, calming the liver and calming the brain. The Compendium of Materia Medica says that cooking can be palatable, and it can remove dampness and diuresis, remove heat and relieve stranguria, open the chest and widen the diaphragm, which makes people calm and has no melancholy, so it is named Xuan. "Li Shizhen also put forward the view that" deer eat nine kinds of detoxified grass, and day lily is one of them ". According to Compendium of Materia Medica, HEMEROCALLIS HEMEROCALLIS "is sweet, cool and nontoxic in nature, relieving vexation and heat, benefiting the chest and diaphragm, calming the five internal organs, and curing red and astringent urine by cooking." It has the effects of stopping bleeding, promoting lactation and diuresis. People often use yellow flowers and sugar to decoct water to treat red and astringent urine; Huanghua plus lotus root node decoction also has obvious curative effect on epistaxis and hemoptysis. According to modern scientific analysis, day lily is rich in sugar, protein, calcium, phosphorus, iron, carotene and vitamin C, among which protein, sugar, calcium, iron and thiamine are among the best in vegetables, and the content of vitamin A is twice as much as that of carrots. Day lily has therapeutic effect on neurasthenia, hypertension, arteriosclerosis, chronic nephritis and edema. Regular and moderate consumption of day lily is of great benefit to disease prevention, health care and longevity. If the elderly with habitual constipation often eat some day lily, it can not only strengthen the stomach and spleen, but also moisten the intestines and relax the bowels, and also nourish the blood and soothe the nerves without side effects. According to reports, Dr. Sun Yat-sen used "Siwutang" as his diet recipe for fitness. "Siwutang" is a good recipe for enriching blood and nourishing blood by cooking day lily, auricularia auricula, bean curd and bean sprouts together, and it is also a cheap and good dish in daily vegetarian diet. However, it is worth noting that fresh yellow flowers contain a substance called colchicine, which generates colchicine oxide in the process of human metabolism. Colchicine oxide has a strong stimulus to human respiratory tract and gastrointestinal diseases, and its main symptoms are nausea, stomach pain, diarrhea, and even hematuria in severe cases. Therefore, in the peak season of day lily, when eating fresh products, don't eat more every time. Because the toxic components of fresh day lily can be weakened or disappeared at high temperature of 60℃, when eating, fresh day lily should be blanched with boiling water first, then soaked in clear water for more than 2 hours, and then taken out and washed with water before frying.
