How to distinguish the true and false Cordyceps wine?

Cordyceps sinensis is a precious nourishing medicinal material, and it is a complex of the daughter of Cordyceps sinensis (a fungus belonging to the genus Cordyceps of ergotaceae) and its host, Cordyceps bat, also known as Cordyceps sinensis. It is a traditional export commodity in China, mainly produced in Sichuan, Qinghai and Tibet. Modern pharmacology has proved that Cordyceps sinensis has the functions of enhancing immunity, anti-arrhythmia, anti-myocardial ischemia, bronchiectasis and anti-tumor. Cordyceps sinensis has extremely high medicinal value. So it is called "gold" in medicine. There are often unscrupulous businessmen in the market, and it is difficult to distinguish between true and false.

Cordyceps sinensis consists of "insect body" and "grass part" (fruiting body growing from the head) (see figure 1). The "worm body" is shaped like a silkworm, fragile and easily broken, and is 3-5 cm long. 0.3-0.8 cm thick. The head is yellowish brown, the section is slightly flat, and the white is slightly yellow. There are 20-30 obviously rough rings on the "worm body" from beginning to end, and the rings near the head are thinner. "Insect body" has 8 pairs of feet, 3 pairs near the head, 4 pairs in the middle and 1 pair near the tail, among which 4 pairs in the middle are the most obvious. "Grass" is dark brown to brown, slender and cylindrical. Generally, it is 4-8 cm long and 0.3 cm thick, with fine longitudinal wrinkles on the surface, slightly enlarged top, flexible texture, broken fibrous surface, yellowish white, slightly fishy and light taste.

High-quality Cordyceps sinensis should be complete. The "worm body" is full and full. Appearance color Huang Liang. The inside is white and the "grass" is short. The following briefly introduces the main identification features of several counterfeit products in case they are cheated when buying.

Cordyceps Liangshan (Figure 3. Another fungus of ergot family). The worm is longer. 3-6 cm, the surface is brown, and there is no obvious "insect foot". The "grass part" is slender, with a length of 10-30 cm and a small diameter, which is yellowish brown to yellowish brown. A few grasses have branches at the top.

Cordyceps Hawkes (fig. 4, another fungus of ergotaceae). Also known as aweto. The surface of the worm is grayish yellow, and the foot is obviously visible. "Grass" is light gray to gray-black, with few branches on the upper part, and the swollen part is mostly black, which is brittle and easy to break, slightly fragrant and light in taste.

Beauveria bassiana (fig. 5. Silkworm body drying). The "worm body" is slightly cylindrical, curved and shrunk, its surface is grayish yellow, covered with white powdery cream (aerial hyphae and molecular spores), and its head is round. 8 feet protruding. No "grass" smell is slightly fishy and salty.

"Cordyceps sinensis" is made of flour, corn flour and gypsum powder. And the "worm" is smooth. It is yellow-white, with obvious ring pattern and heavy weight (Figure 6). The cross section is pale white, and the test will be blue when a small amount of iodine is dropped. If you chew your teeth for a long time, they will loosen if you cook them for a long time. Grass is often disguised by the dry petiole of sweet potato, which is hollow and not easy to break.
