The historical records of Cordyceps sinensis (Cicada flower is the name of a pan-Asian medicinal product) are earlier than Cordyceps sinensis, but its popularity is far less than that of Cordyceps sinensis. There are three reasons:

(1) Cicada sinensis The yield of Cordyceps sinensis is lower than that of Cordyceps sinensis. On average, only about 6 Cordyceps sinensis trees can grow in one acre of wild bamboo forest; and the area of ??bamboo forests in my country is not as large as the alpine meadows of the Qinghai-Tibet Plateau, where Cordyceps sinensis is distributed.

(2) It only takes more than a week from the emergence of Cordyceps sinensis to the time when the flowers wither and wither. It is difficult to pick. The picking period of Cordyceps sinensis is longer than that of Cordyceps sinensis.

(3) From the perspective of medicinal use, systematic research on Cordyceps sinensis started relatively late. It has only been used to treat kidney disease for more than 20 years. Before that, the main effect recorded in medical classics was to treat " "Children with epilepsy, crying at night and heart palpitations" are not as eye-catching as Cordyceps sinensis, which can "protect the lungs and benefit the kidneys", treat various deficiencies and injuries, and has the effect of stopping bleeding and relieving coughs.

Function: Modern scientists have discovered through clinical research that Cordyceps sinensis has the functions of reducing blood creatinine and urea nitrogen levels, increasing endogenous creatinine clearance, increasing plasma albumin, hemoglobin and reducing urinary protein. The effect of protecting kidney function and delaying chronic renal failure is better than that of Western medicine in improving kidney function.

At the same time, the treatment process for patients with chronic renal failure emphasizes a low-protein diet, and patients often suffer from anorexia, indigestion, etc., and have insufficient protein intake. Without drug intervention, it can easily lead to malnutrition. Cordyceps can increase and stabilize the patient's nutritional indicators albumin (ALB) and prealbumin (PA), and its intensity is similar to that of Western medicine, indicating the therapeutic effect of Cordyceps on chronic renal failure. It is relatively comprehensive and can not only improve various biochemical indicators of patients with chronic renal failure, but also adjust the patient's protein energy metabolism and improve their nutritional status. It has obvious advantages compared with Western medicine.

In addition, pharmacological and pharmacodynamic studies on Cordyceps have shown that Cordyceps has the effects of enhancing immunity, lowering blood sugar, lowering blood lipids, improving sleep, scavenging free radicals, and improving anemia. It is useful for tumors, It has good therapeutic effects on diabetes, hyperlipidemia, fatty liver, insomnia, gout, etc.
