The world is full of miracles, and it's really hard to find the plant Cordyceps sinensis. Cordyceps sinensis, also known as "early grass", belongs to Ascomycetes and Ergonomidae, which is mostly produced in Sichuan, Yunnan, Gansu, Qinghai, Tibet and other places in China and is a precious medicinal material in traditional Chinese medicine. Cordyceps sinensis, like its strange name, has a strange shape: it is an animal, its roots are deeply rooted in the soil and there is a grass on its head; It is like a plant, its root is a bug, it has a head and a mouth, and it has eight pairs of neat feet. How did this strange thing of Cordyceps sinensis come into being? Is it a plant or an animal? Why do you have such a strange appearance? It turns out that there is an insect called "bat moth". When spring comes, it lays its eggs in the soil and then dies quietly. After incubating in the soil for 1 month, a white fat larva broke through the soil. A fungus, grasshopper, has been waiting here for a long time. As soon as it meets this white, fat and delicious larva, it burrows into the larva, then absorbs the nutrition from the larva and lives a carefree parasitic life. In winter, larvae burrow into the soil. Because of the reproduction of parasitic bacteria in the body, the worm died before climbing out of the ground. When the climate is warm, fungi will break out of the ground and grow a rod-shaped body with a length of about 10 cm and an oval top on the head of the larva shell. That's why it has grown into such a strange look with both insects and grass. People gave it a strange name "Cordyceps sinensis" according to this strange appearance. Cordyceps sinensis, although it looks strange, is of great use in medicine. It is very effective in tonifying lung and kidney and treating cough, blood in phlegm, asthma, lumbago and other diseases. How did the fungus get into the larva, parasitize in the larva for so long and grow a tree from the insect's mouth? It is still a mystery.
