Cordyceps sinensis is an extremely valuable Chinese herbal medicine and high-grade tonic. Cordyceps sinensis is a combination of insect larvae and fungi, the winter worm is the larva of cordyceps bat moth, and the summer grass is a cordyceps fungus (Trichospora chinensis), both of which mainly grow in the altitude of 3000-4000m in the alpine region, distributed in Sichuan, Yunnan, Guizhou, Gansu, Tibet and Qinghai provinces. As cordyceps sinensis has extremely important edible and medicinal value, wild resources are extremely collected, resulting in fewer and fewer natural cordyceps resources. With the increasing market demand, cordyceps sinensis mycelia is isolated from natural cordyceps sinensis, and the fermentation products are filtered and dried to make finished products through deep fermentation culture. The effect of the mycelia obtained is basically the same as that of natural cordyceps sinensis, but the effect is stronger. Rich in adenosine, polysaccharide and other active substances, not only rich and appropriate proportion, effectively enhance the human body, improve the immune function and anti-fatigue ability. Mycelium powder contains HH2, which is an important component of the female body clock. It can promote the secretion of antibodies in the human body and activate the immune active cells of the body, especially the transformation of lymphocytes and the phagocytosis rate of macrophages.
