Tell me about Cordyceps sinensis. Tell me how to distinguish good from bad. Is it the best in Tibet and Yunnan?

Cordyceps sinensis is a kind of Cordyceps sinensis (fungus, also known as Cordyceps sinensis), and its scientific name is ergotaceae. Its daughter or other Cordyceps sinensis (fungi) are parasitic on the larvae of an insect, Lepidoptera and Cordyceps sinensis of the family Lecanidae, or on the complex of daughter and larva of other insects of the family Lecanidae. The formation of Cordyceps sinensis is that the larvae of Batiaceae are infected with Cordyceps fungi, which makes the larvae become stiff after they get sick and die. Mainly distributed in Qinghai and Tibet.

Identification of Cordyceps sinensis

Authentic Cordyceps sinensis, with a silkworm-like body, yellow-brown surface, many wrinkles on the back, eight pairs of feet in the abdomen, three pairs near the head, four pairs in the middle and 1 pair near the tail, is upright or slightly curved. "Cordyceps" is about 2-5 cm long; "Summer grass" is 2-6 cm long, stalked, often only child, occasionally 2-3 branches, dark brown or brown, thick at the base, tapering upward, slightly enlarged at the upper part, and cylindrical. Soft texture and fibrous section.

Common counterfeits are herbs called "Cordyceps sinensis", but they are also the products of fungal parasitic insects, such as Liangshan Cordyceps sinensis and Cladosporium sinensis, which are similar in appearance to Cordyceps sinensis. There are still people in the market who use the roots of silkworms, bamboo shoots and other plants as counterfeit products, and some even use soybean flour and starch to process them into counterfeit products.

The identification of Cordyceps sinensis can be started from the following aspects:

1, Cordyceps sinensis smells like straw mushroom, with a little fishy smell.

2. The appearance of Cordyceps sinensis, the surface of some "worms" is dark yellow or yellowish brown; The "grass" part shows the color of dead branches; The cross section is milky white, black semicircle or V-shaped.

3. The branched Cordyceps sinensis looks yellow-green, and it is yellow-brown or black-brown after entering the water; Cordyceps Liangshan is brown in appearance and slightly yellow in section. The appearance of ground silkworms is light yellow or gray-black; Cordyceps sinensis made of flour and soybean powder has a brownish red appearance.

4. Cordyceps sinensis in Liangshan and Cordyceps sinensis made of flour and soybean powder are thicker, while the ground silkworm is prismatic or long prismatic, slightly curved.

5. Weight fraud. Soaking Cordyceps sinensis in alum solution to make the surface of Cordyceps sinensis adhere to a layer of alum crystal to increase the weight of Cordyceps sinensis; Insert fine wire into Cordyceps sinensis to increase the weight of Cordyceps sinensis.
