When the mature nymph of cicada becomes an adult, the shell under cicada slough is called cicada slough, also called "cicada slough" or "cicada skin". Its main components contain chitin and protein, which are sweet, salty and cold, and enter the lung and liver meridians. This product is an important traditional Chinese medicine for pungent and cold relieving exterior syndrome.

Cicada is rich in nutrition, with a dry protein content of over 70% and a fat content of about 7%. Its vitamins and various beneficial trace elements are higher than those of ordinary meat food, so it can be called the king of protein in today's food.

Extended data:

In the vegetable market in front of the house in Lishui Liandu, almost every stall is selling cicadas, and the stall owner is busy "pinching the head to the tail" for cicadas, and the citizens who buy them are in an endless stream. The stall owner told us that cicadas would probably go from 30 yuan to 40 yuan per catty, but there were about 90 cicadas per catty, but only 4 cicadas could be squeezed out. In other words, it costs 100 yuan to eat a catty of cicada slough. For Lishui people, this is also a high-grade delicacy.

"Lishui has a long-standing habit of eating cicadas. In the late 1980s, cicadas appeared on the menus of local hotels. The seasonality of eating cicadas is very strong, basically from June to early September. " Chen Jianwei, general manager of a food company in Lishui Nanshan Industrial Park, told the reporter that during this period, the daily wholesale volume of cicadas in Lishui could reach about1.2000 Jin.

In other words, Lishui people eat hundreds of millions of cicadas every year. However, because few people are breeding at present, cicadas on the market are all caught artificially, so Lishui has no time to supply them locally. Many enterprises have begun to ask for supplies from the surrounding areas.
