What are the uses of Sophora japonica? Is it edible? Are there any noble qualities?

There are many poems about Sophora japonica in China's poems, which are used to express sadness and melancholy. In the Tang Dynasty, Luo Ye once wrote a poem called Sophora japonica, the full text of which is "There are many bronze camels outside the palace, and the two sides are planted separately. If you want to get to the autumn season, try to open Jinrui to the Guanhe River. The floor sends hate to the floating pearl foil, and the horse pities the fragrance and shakes the jade. Those who worry about killing rivers and lakes will run around for the rest of their lives every year "(from Complete Tang Poems, vol. 654-9), and others, such as" There are many autumn winds, and Sophora japonica is half a reality "(Autumn Day by Bai Juyi)," In front of the dusk house, Sophora japonica is one inch deep "(Autumn Cool Sleeping by Bai Juyi)," Who lived here in the past year? " Sophora japonica is fragrant and sweet, rich in vitamins and various minerals, and also has the effects of clearing away heat and toxic materials, cooling blood and moistening lung, lowering blood pressure and preventing stroke. After picking it, it can be made into soup, mixed vegetables, braised rice, Sophora japonica cake and wrapped in jiaozi. The most common thing in daily life is steaming Sophora japonica (also known as Sophora japonica Maifan), which is a habit in many areas of China. The method is very simple. Add washed Sophora japonica into flour and mix well, then add seasonings such as refined salt and monosodium glutamate. After mixing well, steam it in a steamer. In addition, Sophora japonica can also be added when making porridge and soup. Although Sophora japonica is delicious, there are some taboos when eating it. Because Sophora japonica is sweet, diabetics had better not eat more. Powdered steamed Sophora japonica is not easy to digest, and people with poor digestive system, especially middle-aged and elderly people, should not eat too much. At the same time, people with allergic constitution should also be careful to eat Sophora japonica. Sophora japonica is not only edible, but also a good medicine. Generally, it is harvested in summer when flowers bloom or buds form, and it is better to have a large, compact, yellow-green leaf without stalks. Main ingredients: raw Sophora japonica mainly contains Rutin or its compounds, in addition, wax, green pigment, resin, condensed tannin, pigment, protein (or mucus), amino acids (or peptides), sugar and vitamin A, etc. The fried Sophora japonica is basically the same as raw Sophora japonica, only some amino acids (or peptides) or sugar are destroyed, and the tannin content is slightly increased. Betulin, Sophoradiol, glucose and Glucuronic acid)． are obtained after hydrolysis. Sophora japonica L, B and C are also obtained from flower buds. A is a flavonoid different from rutin. B and C are sterols. Rutin in Sophora japonica can be hydrolyzed into quercitrin under the action of acid or enzyme. Pharmacological effects: 1. Effect on cardiovascular system. Sophora japonica flower liquid has a slight exciting effect on isolated frog heart and a blocking effect on cardiac conduction system. Rutin, quercetin and quercitrin can also increase the contraction and output of isolated and in situ frog heart and slow down the heart rate. Quercetin can dilate coronary vessels. Improve myocardial circulation. Rutin can make the blood vessels of toad's lower limbs and rabbit's ears contract. Sophora japonica liquid and Sophora japonica tincture can temporarily significantly lower blood pressure in anesthetized dogs and cats. Rutin and its preparation can also lower blood pressure in a short time. 2. Effect on blood lipid. Subcutaneous injection of quercetin 1 １０mg can effectively reduce the cholesterol content in liver, aorta and blood of experimental hypercholesterolemia rats. And increase the stability of cholesterol-protein complex. It has preventive and therapeutic effects on experimental arteriosclerosis. 3. Effect on capillaries. Rutin and its aglycone quercetin can maintain the normal resistance of capillaries, reduce vascular permeability, and restore the normal elasticity of capillaries bleeding due to increased brittleness. Quercetin can enhance the resistance of skin capillaries in guinea pigs and rats and reduce vascular permeability. Its stability to capillaries is 1/3 stronger than that of rutin. Continuous application of rutin and quercetin in large quantities can prevent pulmonary hemorrhage in rats caused by decompression. 4. Anti-inflammatory effects Rutin and quercetin can inhibit paw edema and ankle edema caused by histamine, egg white, 5-hydroxytryptamine, formaldehyde and polyvinylpyrrolidone in rats. Rutin can significantly inhibit traumatic edema in rats. It can also prevent conjunctivitis, auriculitis and pulmonary edema. It has only a slight inhibitory effect on conjunctival edema caused by mustard oil in rabbits, such as dissolving rutin in propylene glycol. The effect of preventing inflammation is better. Rutin intravenous injection can inhibit allergic inflammation of skin and joints caused by horse serum in rabbits. The sodium salt of Rutin sulfate can accelerate the recovery of thrombophlebitis in hind limbs caused by turpentine injection in dogs. 5. Spasmodic and anti-ulcer effects Quercetin can reduce the tension of intestinal and bronchial smooth muscles, and its spasmolytic effect is five times stronger than Rutin. Rutin can reduce the gastric motility function of rats. It can also relieve the spasm of small intestinal smooth muscle caused by barium chloride. Subcutaneous injection of rutin 5 ~ 1 mg/kg can significantly reduce the number of lesions of gastric ulcer caused by ligation of pylorus in rats, and its effect on reflex gastric ulcer is better than that of Kai Lin Qiang. Injection of Sophora japonica liquid (containing little rutin) into rabbit intestinal cavity can stimulate intestinal mucosa and increase exudate. 6. Anti-pathogenic microorganism effect of Sophora japonica water immersion agent (2: 5), In vitro, it has inhibitory effects on dermatopathogenic fungi such as Trichophyton violaceum, favus xulan, Trichophyton odoratum, Trichophyton woollen, Nocardia stellata, etc. In vitro, rutin and quercetin have antibacterial effects on some bacteria. Other effects Rutin has a protective effect on X-ray irradiation. Sophora japonica contains hemagglutinin, which can agglutinate blood cells. A large dose of Sophora japonica tincture can inhibit some central reflex functions. It is generally believed that Rutin can not be absorbed orally, so it is uncertain whether it has a therapeutic effect. However, some reports have pointed out that it can still be absorbed after oral administration. Experiments show that Sophora japonica charcoal decoction is given to mice by gavage. It can obviously shorten the bleeding time and coagulation time. Its hemostatic and coagulation effects may be related to its tannin content or contain other hemostatic and coagulation components. Sophora japonica charcoal can shorten the traumatic bleeding time and reduce the amount of bleeding in rats. The Sophora japonica solution without rutin has significant hemostatic effect on traumatic bleeding in rats. Rutin has obvious inhibitory effect on punctate hemorrhage and experimental pulmonary hemorrhage caused by skin negative pressure. Rutin can prevent experimental frostbite by gavage in rabbits. Compatibility effect: Flos Sophorae Immaturus is compatible with Gardenia: Flos Sophorae Immaturus tastes bitter, cools blood and stops bleeding, and can clear away intestinal heat and purge excess fire in liver meridian; Gardenia is bitter and cold, which can clear qi, promote diuresis and stop bleeding. Stir-frying charcoal as medicine has the effect of cooling blood and stopping bleeding in clearing heat. The combination of Gardenia and Sophora japonica has the effect of clearing lung, clearing intestine and stopping bleeding. If fried charcoal is used as medicine, the hemostatic effect will be stronger. It can be used to treat bloody stool, hemorrhoid bleeding, bloody dysentery and metrorrhagia due to excessive fire in large intestine or damp-heat accumulation.
