Cordyceps can be used to treat kidney disease. According to Chinese medicine, Cordyceps enters the lung and kidney meridians and has the function of tonifying the lung and benefiting the kidney, stopping bleeding and resolving phlegm, which can treat various symptoms caused by deficiency of kidney energy. It is also clinically found that Cordyceps has a good anti-glomerular fibrosis effect and can delay kidney failure. Therefore, kidney disease patients, especially chronic kidney disease patients, can delay the deterioration of kidney function and protect kidney function if they take Cordyceps for a long time. However, due to the expensive price of Cordyceps, long-term use is more expensive and generally difficult to afford, so the clinical use of artificial Cordyceps powder for kidney disease, such as Bai Ling tablets, Jin Shui Bao and other drugs, long-term treatment of kidney disease, lung and kidney supplementation effect is better.
