Cordyceps sinensis is a kind of precious Chinese herbal medicine with the same function as ginseng. It resembles a silkworm and has an odd shape. It is a worm and a grass, which not only benefits the lungs and kidneys, stops coughing and asthma, but also eliminates fatigue, nourishes and strengthens the body, inhibits tuberculosis and hepatitis bacteria, and has certain anti-cancer and anti-aging effects. In my early years of work, I participated in the research of animal experiments, and the results proved that Cordyceps has a very good effect on the prevention and treatment of acute kidney injury caused by drugs and ischemia. Modern scientific research has found that Cordyceps sinensis polysaccharides and cordycepic acid may play a positive role in improving the microcirculation and local blood flow in the kidney and promoting renal tubular regeneration, which can help restore the function of damaged kidney units with rational use. At present, Cordyceps is mainly used in various diseases such as renal insufficiency, renal failure, glomerulonephritis, nephrotic syndrome and diabetic nephropathy. However, the role of Cordyceps has been overly deified in recent years, and the commercial purpose behind it is very obvious. As a clinical doctor who has been engaged in this research, I can say responsibly that Cordyceps is not a miracle cure for all diseases; it is not a catalyst to promote your rejuvenation; its production cannot be so large that it can be made into tablets to eat; its price should not be so outrageous! To put it bluntly, it’s all a business trap! There is no need to consume wild cordyceps for chronic kidney disease, because distant water can not quench the thirst of the near. Many kidney diseases are triggered by a combination of genetic constitution, poor lifestyle habits (obesity, high-salt diet, staying up late), combined with other diseases (diabetes, hypertension, gout, lupus erythematosus), and other factors. The occurrence and development of kidney disease is a chronic process, especially in patients with prolonged disease, the structural changes in the kidney have long been transformed from quantitative to qualitative changes, if these triggers are not removed, you can’t cure your disease even if you soak in a worm tank. For some patients with acute kidney damage (acute blood loss, drug poisoning, traumatic shock), in addition to actively correcting blood loss and removing toxins from the body, wormwood preparations have the potential to play a role in reducing kidney damage, promoting recovery of kidney function, and shortening the course of the disease. People who are not sick take cordyceps is even more superfluous, health is not eaten, but created by regular life and scientific body care. Cordyceps is just grass, not God, spend money to eat cordyceps is really better than good mouth, open legs!
