It was recorded as a chinese medicine in the Chong era (a chinese dynasty during the Middle Ages). In an early botany book, it was written that vegetable waspe and plant worms protect the lungs, strengthen kidneys, stop bleeding, diminish phlegm, and stop coughing. Even in Chinese medical science, which is rich in history and tradition, says that 'Vegetable wasps and plant worms are worms but not worms and are plants but not plants. They are just God's medicine.' Therefore, they are known for having mysterious powers in themselves. The meaning of vegetable wasps and plant worms comes from ancient China which means, 'Living in a body of an insect absorbing its nutrients to death in winter and then making a mushroom at its dead body in summer.' Therefore, they can be distinguished between being animals or plants.

Namely, a kind of mold included in soil, the fungus of vegetable wasps and plant worms enters into a body of a live insect through the respiratory and the digestive organs, as well as through varying joints. It then raises and bleeds, taking nutrients from the insects. After the main insect dies, it begins making mushrooms on it. The infected insect maintains its appearance like a mirror, not decaying. It is a king of parasitic insect mushroom used for medicine.

Originally, vegetable wasps and plant worms that came out from a larvae of a species of batmoth 'cordyceps sinensis' were called vegetable wasps and plant worms. But today, all mushrooms from a spider and fungi as well as insects are called vegetable wasps and plant worms.

Vegetable wasps and plant warms are a sort of a mushroom that is a bleeding organ of mold. It is divided into 3 parts which includes 1) a head that has a bleeding organ, 2) a stem which supports the head, and 3) a root. But normally, only the head and stem areas are considered part of the mushroom. Mushrooms can be classified by the shape as oval type, bar type, pot type, needle type, rectangle type, snow flower type, and noodle type. The size ranges from as small as a mm to as large as over 10cm or more. The colors of the mushrooms range from red, yellow, purple, green black, white, orange, and olive. There are about 300 species in the world.
