Taste of cicada: sweet; Cold; Non-toxic indications: exogenous wind and heat; Have a fever; Dizziness; Sore throat; Early single-board computer rash; Poor eruption; Convulsions in children; Eyes red and swollen; Masks cover the eyes; Studies at home and abroad show that cicada flower has multiple effects of improving immunity, resisting fatigue, protecting kidney, improving sleep, resisting tumor, protecting liver, resisting radiation and improving eyesight, and it is a magical ancient Chinese medicine. The cultured cicada flower contains mannitol 2. 18%, polysaccharide 2 1.73%, amino acid 19.76%, cordycepin 0.005% and adenosine 0.05%, which is similar to natural cordyceps sinensis, but no toxic heavy metals such as arsenic, mercury and lead are detected. Therefore, cicada flower can be used as a substitute for Cordyceps sinensis, and it can also achieve the function of nourishing and preserving health. Chen Wanqun and other reports show that the amino acids of cicada flower are similar to many kinds of cordyceps, and the content is the same. Scholars recognize that various amino acids are one of the material bases for nourishing and strengthening. Pharmacological experiments show that amino acids of cicada flower and various cordyceps have different degrees of nourishing, anti-fatigue and anti-stress effects. The water decoction of cicada flower can obviously prolong the swimming time of experimental mice and significantly improve the survival time under normal pressure and high temperature, which proves that cicada flower has anti-fatigue and anti-stress effects. After 65438±0h hours of sedation and hypnosis, the number of spontaneous activities in cicada flower group was significantly less than that in control group. Cicada can also significantly prolong the sleep time of mice and shorten the disappearance time of pentobarbital sodium righting reflex; Cicada can also improve the sleep rate of mice in unit time. This proves that cicada flower has a good sedative and hypnotic effect. At the same time, it is proved that the effect of artificial culture is similar to that of natural cicada. Antipyretic and analgesic effects cicada flower has obvious cooling effect on normal and artificial fever rats within 2 hours after administration; The results of writhing method and hot plate method show that cicada flower has a very significant inhibitory effect on chemical and burning stimulation pain in mice. This proves that cicada flower has a good antipyretic and analgesic effect. Both this experiment and Chen Zhuan's experiment prove that the artificial culture of cicada flower has the same effect. Immunoregulation: Cordyceps sinensis polysaccharide was extracted from cicada mycelium by artificial fermentation, and the reference test of Grifola frondosa polysaccharide was carried out. Lymphatic transformation test, Ea and E rose test, specific immune rose test (macrophage phagocytosis test) and anti-sheep red blood cell (SRBC) antibody titer test showed that cicada polysaccharide could obviously improve immune function and renal function. The clinical study of replacing Cordyceps sinensis with cicada flower shows that it can reduce serum and urine creatinine, improve endogenous creatinine clearance rate, increase serum protein content and reduce urinary protein excretion. Therefore, it is effective for patients with chronic renal insufficiency in the early and middle stages. Further research confirmed that cicada flower has a good effect on tubulointerstitial lesions, which can protect renal tubular cells Na+-K+-ATPase, reduce lysosomal injury and lipid peroxidation, improve renal hemodynamics, and reduce endothelial cell injury and coagulation function. Therefore, it is considered that cicada flower can improve renal function. Other literature reports that adenosine in cicada flower can lower blood pressure and slow down heart rate. It is also found that cicada flower has anti-radiation and anti-tumor effects. As mentioned earlier, cicada flower has a nourishing and strong effect, which will definitely improve its vitality and have a certain anti-radiation effect; Cicada can improve immune function, directly or indirectly engulf or inhibit tumor cells, showing its anti-tumor effect. Cicada is an ancient and precious medicinal material, which belongs to the same insect-fungus complex as Cordyceps sinensis. Their strain is Paecilomyces, which contains similar chemical components, so doctors often use it as a substitute for Cordyceps sinensis. Due to the shortage of medicinal resources, its research and application are still very few. According to existing reports, the chemical composition of cicada flower is complex and its pharmacological effects are extensive, so it is necessary to study and develop it. Fortunately, Paecilomyces cicadae strain has been isolated and purified from cicada flower, and artificial cultivation of cicada flower has begun. The future research and application prospects are very good. In the near future, cicada flower preparation may face the market, serve the medical and health care cause and benefit the people. Cordyceps sinensis has the functions of nourishing lung yin and tonifying kidney yang, and can be used as a food supplement for nourishing lung and kidney, stopping bleeding and resolving phlegm, protecting lung, eliminating dysentery and relieving cough. According to the modern research results of pharmacological action, Cordyceps sinensis in Qinghai contains about 7% of cordycepic acid, 28.9% of carbohydrate, 8.4% of fat, 25% of protein, and 82.2% of fat is unsaturated fatty acid. In addition, it also contains vitamin B 12, ergot fatty alcohol, hexahydrosugar alcohol and alkaloids. According to medical scientific analysis, Cordyceps contains cordycepic acid. Vitamin B 12, fat, protein, etc. Cordyceps sinensis is sweet, mild and nontoxic. It is a famous tonic and strong medicine. Often used in stew, it has the effect of tonifying deficiency and strengthening the body. It is suitable for treating hemoptysis, blood in sputum and cough caused by lung-qi deficiency, lung-kidney deficiency and tuberculosis. Shortness of breath, night sweats, etc. It also has a good effect on impotence due to kidney deficiency and soreness of waist and knees. It is also a nourishing product for the elderly and infirm. Ten-effect Cordyceps sinensis is a precious Chinese herbal medicine in China, and it ranks as one of the three nourishing medicinal materials in China along with ginseng and velvet antler. As early as 1757, it was recorded in Materia Medica Congxin that "Cordyceps sinensis can protect lung and benefit kidney, replenish essence, stop bleeding and eliminate phlegm, and treat diaphragmatic fatigue". Chinese medicine believes that Cordyceps sinensis can not only replenish lung yin, but also tonify kidney yang, and mainly treat impotence due to kidney deficiency, nocturnal emission, soreness of waist and knees, physical weakness after illness, chronic cough and expectoration. It is the only Chinese medicine that can balance and regulate yin and yang at the same time. Cordyceps sinensis is not a "worm" in winter and a "grass" in summer, but a kind of fungus-Cordyceps sinensis of ergotaceae. Modern science has discovered more and more magical effects of Cordyceps sinensis. Generally speaking, Cordyceps sinensis not only has the function of regulating various organs of human body, but also has some direct disease-resistant functions. First, regulate the function of the immune system. The immune system is equivalent to the army in the human body, which resists tumors internally, removes aging and necrotic cell tissues, and resists microbial infections such as viruses and bacteria externally. The human body may have mutated tumor cells every day. People with normal immune system function can escape the bad luck of tumor, but people with poor immune system function may develop tumor. The effect of Cordyceps sinensis on the immune system seems to be to adjust the volume to make it in the best state. It can not only increase the number of cells and tissues in the immune system, promote the production of antibodies, increase the number of phagocytes and killer cells, enhance their functions, but also reduce the functions of some immune cells. Second, the direct anti-tumor effect Cordyceps sinensis extract has a clear inhibitory and killing effect on tumor cells in vitro. Cordyceps sinensis contains cordycepin, which is the main component of its anti-tumor effect. The clinical use of cordycepin is mostly adjuvant therapy for malignant tumors, and the symptoms are improved by more than 9 1.7%. It is mainly used for patients with malignant tumors such as nasal cancer, pharyngeal cancer, lung cancer, leukemia and brain cancer. The content of cordycepic acid in Cordyceps militaris is 3.09 g, and that in wild Cordyceps militaris is 5.54 g.. Cordyceps acid is a kind of D- mannitol, which can increase the osmotic pressure of plasma and make the water in the tissue enter the blood vessels, thus reducing tissue edema and replenishing plasma. Third, improve cell energy and anti-fatigue. Cordyceps sinensis can improve the energy of mitochondria, the energy factory of human body, improve the cold tolerance of the body and reduce fatigue. Fourth, regulating heart function Cordyceps sinensis can improve the hypoxia tolerance of the heart, reduce the oxygen consumption of the heart, and resist arrhythmia. V. Regulating liver function Cordyceps sinensis can reduce the damage of toxic substances to the liver and prevent the occurrence of liver fibrosis. In addition, it also plays a beneficial role in viral hepatitis by regulating immune function and enhancing antiviral ability. Sixth, regulate the function of respiratory system Cordyceps sinensis has the functions of dilating bronchi, relieving asthma, eliminating phlegm and preventing emphysema. Seven, regulating renal function Cordyceps sinensis can alleviate the renal lesions of chronic diseases, improve renal function, and reduce the damage of toxic substances to the kidney. Eight, regulating hematopoietic function Cordyceps sinensis can enhance the ability of bone marrow to produce platelets, red blood cells and white blood cells. Nine, regulating blood lipids Cordyceps sinensis can reduce cholesterol and triglycerides in the blood, increase high-density lipoprotein beneficial to the human body, and reduce atherosclerosis. 10. Other Cordyceps sinensis also has the functions of directly resisting virus, regulating central nervous system function and regulating sexual function. It is amazing that Cordyceps sinensis can play such a comprehensive health care role on human body, and it is worthy of the reputation of "Cao Xian" since ancient times. In modern society, taking Cordyceps sinensis is not only a guarantee for your own health, but more importantly, it brings the ultimate healthy quality of life. The anti-fatigue effect of Cordyceps sinensis is a very common phenomenon. It can be divided into two types: disease fatigue and non-disease fatigue. Generally speaking, as long as non-disease fatigue can be eliminated through sleep, exercise, entertainment and other means. But the disease fatigue is not good, and the symptoms can only be eliminated by drug treatment. The discovery of Cordyceps sinensis can not only prevent disease fatigue, but also prevent non-disease fatigue-a lot of lactic acid and metabolites will accumulate in muscle tissue after exercise or fatigue. Cordyceps sinensis can regulate human endocrine, speed up blood flow, further promote the normal metabolic activity in the body, quickly remove lactic acid and metabolites, make serum enzyme indexes quickly return to normal, and achieve the effect of quickly restoring body function. Therefore, Cordyceps sinensis has anti-fatigue effect.
