Cordyceps sinensis can be eaten, but it must be cleaned, because there is dirt on Cordyceps sinensis and many people have held it upside down. It is recommended to soak it in hot water before eating. Cordyceps sinensis can also be used for decoction, stewing soup, soaking medicinal liquor, etc.

Cordyceps sinensis (scientific name: StachysgeobombycisC.Y.Wu) is a stachys plant of ergotaceae, and the fungus Cordyceps sinensis is parasitic on the stroma of the insect larvae of Hymenoptera and the dry complex of the larvae.

In summer, after the ascospores shoot out of the ascospores, they produce germ tubes (or germ tubes from conidia), which penetrate into the host larvae and grow. The infected larvae burrow into the soil and form sclerotia in winter, which destroys the internal organs of the larvae, but the horny skin of the larvae is still intact. The next summer, a daughter is born from the front end of the larva's body.
