Also known as Cordyceps sinensis, it is very strange that insects and grass grow together. Winter is an insect, from which grass grows in summer. Insect is the larva of Cordyceps bat moth, and grass is a kind of Cordyceps. How did it grow? In summer, insects lay their eggs on the leaves of grass and then fall to the ground with the leaves. In a month or so, they hatch into larvae and then drill into the wet and soft soil. There is an ascospore of Cordyceps sinensis in the soil layer, which only attacks those obese and well-developed larvae. After being attacked by spores, the larvae burrow into the shallow layer of the ground. Spores grow in the larvae, and the internal organs of the larvae slowly disappear, becoming a body covered with hyphae and buried in the soil. After a winter, when the next spring comes, hyphae begin to grow, and in summer, they grow out of the ground and grow into a grass. In this way, the body of the larva and the grass together form a complete "Cordyceps sinensis".

Cordyceps sinensis belongs to ergot family, and the dried Cordyceps sinensis body is connected with the fungus base, with a total length of 9~ 12 cm. The worm is like a three-sleeping old silkworm, with a body length of 3~6 cm and a diameter of 0.4~0.7 cm. The surface is brown and rough, and there are many horizontal wrinkles on the back. There are 8 pairs of feet in the abdomen, and 4 pairs of feet are obvious in the middle. Its characteristics, such as silkworm body, are light and brittle, easy to break, with white cross section, dark yellow around and full cross section. The mycelium at the head of the worm is rod-shaped, curved, slightly swollen at the upper part, with a grayish brown or dark brown surface, up to 4~8 cm long, slightly smelly, especially the worm is bright yellow, plump and plump, with a yellow-white section and short mycelium.

When Cordyceps sinensis is soaked in boiling water, the insect body becomes swollen and soft, and the color of the fungus base becomes dark brown, and the insect body is closely connected with the fungus base and does not fall off. The immersion liquid has a slight smell.

Due to the high price of Cordyceps sinensis, large dosage and short supply, some unscrupulous traders try their best to make fake Cordyceps sinensis. Some use silkworms and bamboo shoots to make fake Cordyceps sinensis, and there is no physical and chemical identification method, which is difficult for some Chinese medicine experts with strong identification ability to identify.

However, as long as you have high discrimination ability and observe carefully, you can still identify it. The color of fake Cordyceps sinensis is slightly yellow than that of real Cordyceps sinensis, but it is not bright. Look carefully, it is yellow and punctate, smelly, with white cross section, dark spots and pith cavity. Other appearances are exactly the same as those of Cordyceps sinensis. After soaking in boiling water for 10 minutes, Cordyceps sinensis will slowly show its original shape, yellow embryos will fall off, and pseudobacteria will begin to fall off and separate from the insect body. Some worms become plant roots, ground silkworms, and some become stiff silkworms. The fungus base gradually turned into a white day lily, and the dark brown completely faded. The soaked boiled water gradually turns light black and slightly sticky. It is hoped that users will pay attention to identification and prevent fake cordyceps from endangering people's health.
