What is the function of Cordyceps sinensis and how to distinguish good from bad.

Cordyceps sinensis: Cordyceps sinensis contains protein, fat, cordyceps acid, vitamin B and other ingredients, which have an important impact on many physiological functions of the human body, such as significantly promoting the body's immunity, and can play a role in sedation, anticonvulsant and hypothermia of the central nervous system; It can dilate the bronchial tubes, expelle phlegm and relieve asthma of the respiratory system, and has significant effects on chronic nephritis and renal failure.

Identification method of real and false cordyceps.

Cordyceps sinensis is a valuable Chinese medicinal material. At present, some lawbreakers in the market, in order to make illegal profits, actually use Liangshan Cordyceps, Branched Cordyceps and Silkworms to pass off as Cordyceps, so that many people are deceived. Therefore, when buying Cordyceps, it is necessary to pay attention to the identification of real and fake Cordyceps.

The methods are: First, it is identified from the form. Cordyceps sinensis is like a silkworm. 3-5 cm long, about 0 3-0 8 cm thick; Liangshan Cordyceps and Cordyceps made of flour and soybean flour are thicker in shape, and the silkworm is prismatic or oblong, slightly curved.

The second is to identify from the ring pattern. Cordyceps sinensis ring pattern is rough and obvious, near the head ring pattern is fine, a total of 20-30 ring lines, Liangshan Cordyceps ring pattern is numerous; There are only 2-11 root marks in the silkworm.

The third is to identify from the surface color. Cordyceps sinensis has an earthy yellow or yellowish brown appearance; Cordyceps branching is yellow-green in appearance and yellowish-brown or black-brown when it enters water; Liangshan Cordyceps has a tan appearance; The appearance of ground silkworms is pale yellow or grayish-black; Cordyceps made from flour and soybean flour has a brownish-red appearance.

Fourth, it is identified from the insect feet. Cordyceps sinensis has 8 pairs of feet, 3 pairs near the head, 4 pairs near the middle, and 1 pair near the tail, of which the middle 4 pairs are the most obvious. There are 9-10 pairs of Liangshan Cordyceps, which is 1-2 pairs more than Cordyceps, and the feet of other Cordyceps are not obvious enough.

The fifth is to identify from the fruiting body of the head. The body of the head of Cordyceps sinensis is dark brown, cylindrical, 4-8 cm long, thick cm, with fine longitudinal wrinkles on the surface, the top is slightly expanded, the body of the head of Cordyceps sinensis is black-brown, with more than 1-3 branches, the stalk is thin and curved, and it is easy to peel off after wetting; The fruiting body of the head of Cordyceps liangshan is longer, much larger than the insect body; The fruiting body of the head of Cordyceps made of flour and soybean flour has fine longitudinal wrinkles.

1. Cordyceps sinensis should look at the overall color of Cordyceps sinensis when choosing, generally speaking, the first half of the cordyceps is thicker, the color is mainly dark brown is the best, the light brown indicates that the medicinal value is slightly worse, the tail color is darker, and the one with a large hook is the best.

2. Cordyceps sinensis has its own feet, which is also a key to distinguish the quality of Cordyceps, a good Cordyceps sinensis has three links in each foot, you can count them carefully, if the links are vague or not enough, then the quality of Cordyceps sinensis is not good.

3. When choosing Cordyceps, it is necessary to see whether the whole Cordyceps sinensis is rotten, or whether there is any damage, you can gently pinch it with your hands, if you feel a soft place, then it means that there are signs of decay inside the Cordyceps.

Cordyceps is a precious bai traditional Chinese medicine, and the quantity is not much

Therefore, the value is expensive.

Zhi, tens of thousands of yuan per kilogram, especially the price of Qinghai-Tibetan Cordyceps is much higher than that of Cordyceps in other places due to its high quality.

The difference is about 6,000 yuan. In order to make huge profits, unscrupulous businessmen mislead consumers by inserting iron wires, fuses or injecting mercury into the body of insects, and wrapping soil mixed with fine metal powders such as iron powder and lead powder. Consumers who lack professional knowledge can choose big brands such as FLM and Tong Ren Tang for cordyceps sinensis, which is of better quality.

Tongrentang's ** is more expensive, about 2 times that of FLM, which is more affordable and suitable for home use.

Cordyceps identification method (

**): Cordyceps sinensis overall:

The head is slightly like a dead tree branch

The eyes are brownish-red, the first three pairs of feet are degenerate, the right precursor is darker, the body ring is clear, there are four pairs of legs in the middle of the torso, the overall surface of Cordyceps is dark yellow to brown, and there is a pair of feet on the tail.

1.The color of the real Cordyceps sub-seat is gradient, and the thickness of the fake Cordyceps sub-seat is uniform without gradient color.

2.【Look at the eyes】Real Cordyceps eyes are brown or brownish, fake Cordyceps eyes are dark red.

3.【Look at the neck】The neck of the real Cordyceps changes from light yellow to dark yellow, and the fake Cordyceps has no color mutation.

4.【Look at the right feet】The real Cordyceps has clear feet, three pairs of degraded middle feet, four pairs of large feet and one pair of feet on the tail, and the characteristics of the feet of the false Cordyceps are not obvious.

5.【Look at the texture】The back lines of real Cordyceps are clear and regular, generally three thin and one thick, and the back lines of fake Cordyceps are chaotic and unclear.

6.【Identification of soaking in water】The real Cordyceps will not fade after soaking in water, and the fake Cordyceps will not fade after soaking in water, and it tastes bitter.

The main ways to identify the authenticity of Cordyceps sinensis are:

1. Body recognition.

Cordyceps liangshan, which is often used to pass off as Cordyceps, and Cordyceps, which is made from noodles and soybean flour, are coarse. Silkworms are prismatic or oblong, slightly curved; Some empty shell Cordyceps, after extracting the active ingredients, this supplement has less content, the appearance is not full, break it and look closely, you can also find foreign objects such as inserted wires.

2. Ring pattern recognition.

Cordyceps sinensis has rough and obvious rings, and the rings near the head are fine, with a total of 20-30 rings. Silkworms only have 2-11 root traces.

3. Surface color recognition.

Cordyceps sinensis has an earthy yellow or yellowish brown appearance. Cordyceps branchiculus has a yellowish-green appearance and is yellowish-brown or black-brown when it enters water; Liangshan Cordyceps has a tan appearance; The appearance of ground silkworms is pale yellow or grayish-black; The appearance of flour and soybean flour insect leather is brownish-red; Cordyceps sinensis soaked in alum has a milky white color on the surface.

4. Insect foot identification.

Cordyceps sinensis has 8 pairs of feet in the whole body, of which 4 pairs are the most obvious in the middle; There are 9 to l0 pairs of Liangshan Cordyceps, which is 1 to 2 pairs more than Cordyceps, and the feet of other Cordyceps are not obvious enough.

5. Head fruiting body recognition.

Cordyceps sinensis head fruiting body dark brown, cylindrical, 4 to 8 cm long, coarse, with fine longitudinal wrinkles on the surface, slightly enlarged at the top; The fruiting body of the head of Branched Cordyceps is black-brown, with more than 1-3 branches, the stalk is thin and curved, and it is easy to peel off after wetting. The fruiting body of the head of Cordyceps liangshan is longer, much larger than the insect body; There are no fine longitudinal wrinkles on the fruiting body of the head of Cordyceps made of flour and soybean flour.

6. Water test method.

Cordyceps is soaked in boiling water, the insect body becomes larger and softer, the insect body and the fungus seat are closely connected, do not fall off, and the infusion is slightly odorous; After soaking the false cordyceps in boiling water for 10 seconds, it will slowly show its original shape, the yellow opening fetus falls off, the false bacterium also begins to fall off, and separates from the insect body, some of the insect body becomes plant rhizomes, ground silkworms, and some become zombie silkworm bodies, the bacterium slowly becomes a white-like daylily, the black-brown color completely fades, and the soaked boiling water gradually becomes light black and slightly viscous.

7. Taste and smell.

Cordyceps is chewed in the mouth like chewing green edamame, the more you chew, the more fragrant it becomes, and the mouth is full of sweet and fragrant chicken; Pseudocordyceps is chewed in the mouth, the top teeth are crushed, and the mouth is soaked with mud powder, which is not chewy and has no meat fragrance, and the earthy taste is very strong. The moist cordyceps sinensis is opened after sealing, and it smells relatively strong aroma of straw mushrooms and shiitake mushrooms; When dried, it smells tasteless or has a faint aroma of straw mushrooms and shiitake mushrooms, while counterfeit products do not.

How to identify real and fake Cordyceps

1. Recognize the color of the grass: "color" brown and yellow. Cordyceps sinensis is yellow to brownish yellow on the surface, the head is yellow-red, and most of the "grass heads" are black, slender, flat in section, and slightly yellowish in color.

**Cordyceps is preferably yellow and clean, bright, plump and hypertrophied, yellowish-white in section, not hollow, short in sub-seat, no mildew, and no impurities.

2. Look at the grass shape: "shape" is like a silkworm. Cordyceps sinensis is like a silkworm, generally has only one "grass head", and there are very few Cordyceps with multiple branches of "grass head", the base of the "grass head" is thicker, the end is tapered, and the length is in.

1 4 cm. **Cordyceps has a rough surface with obvious rings, with a total of 2 3 rings. Dried cordyceps is brittle and easy to break.

After Cordyceps is broken, there is a small horseshoe-shaped imprint in the section that is hollow or light gray. Cordyceps is mostly slender or slightly curved. However, Pseudocordyceps is a symmetrical bump on one side and equal stripes with parallel voids on the other, which is generally poured out of molds.

3. Cordyceps: Cordyceps sinensis is soaked in boiling water, the insect body becomes swollen and soft, the color of the fungus base is aggravated and becomes black-brown, and the insect body and the fungus are closely connected and do not fall off. The infusion has a slight odor.

After soaking the pseudocordyceps in boiling water for 1 minute, it will slowly show its original shape, the yellow womb will fall off, and the pseudocyptic base will also begin to fall off, separating from the insect body.

4. Smell the grass: the "taste" is strong. The genuine product has a natural mushroom aroma or a slightly fishy smell, and the fake product is generally odorless.

Smell: **Cordyceps sinensis has a slightly dry and rotten body of fishy algae and mixed with the aroma of straw mushrooms, which is the unique taste of Cordyceps;

Color: The surface of the "insect" of Cordyceps sinensis is dark yellow to light yellowish brown; The "grass" part is the color of dead branches, i.e. dark brown or light brown;

Look at the section: the fracture surface of the "insect" body of Cordyceps sinensis is milky white, which is similar to the section of the zombie silkworm;

Appearance: The part of the main body of Cordyceps sinensis is cylindrical, light in color, and has fine longitudinal lines on the surface. The part at the top that connects with the "grass" is slightly expanded.

The part of the grass is darker and smaller, so it is called "grass", that is, the sub-seat, stalked, often solitary, occasionally with 2 or 3 branches.

Three key points for precise identification.

Size: The body of Cordyceps sinensis is 3 5 cm long and cm in diameter. In this range, the longer and thicker the cordyceps, the better the quality.

Sufficient number: Cordyceps sinensis has 8 pairs of feet, 3 pairs near the head, 4 pairs in the middle, and 1 pair near the tail, of which the middle 4 pairs are the most obvious;

Look at the ring pattern: the ring pattern of Cordyceps sinensis is rough and obvious, and the ring pattern near the head is fine, with a total of 20 30 ring lines;

Examples of common Cordyceps counterfeits.

From the appearance identification, plus these data, the authenticity and quality of Cordyceps sinensis can be identified. Here are some common counterfeits of cordyceps.

Branching Cordyceps. The fungus Mycocordyceps fungus of the Ergogram family parasitizes the fruiting body and larval body complex on the larvae of lepidopteran insects. The appearance of this product is yellow-green, the sub-seat is solitary or branched, 5 8 cm long, the stalk is curved, black, longitudinal wrinkles or ridges, the upper part is smooth, and the lower end has fine hairs.

The fruiting body head is short cylindrical, brown.

Dear, hello, the method of identifying Cordyceps sinensis is: Cordyceps sinensis is usually dark yellow to yellow-brown on the surface, rough, with 2 to 30 rings on the back, etc. The main characteristics are that the larval body is like a silkworm, the surface is dark yellow to yellowish-brown, the surface is rough, there are 2 to 30 rings on the back, there are thin rings at the end, the head is reddish-brown, there are 8 pairs on the ventral surface, 4 pairs of which are obvious, green and easy to break, the cross-section is full, white or light yellow, the periphery is dark yellow, the base is slender cylindrical curved, the lower part is slightly thicker, the upper part is slightly expanded, the surface is dark brown to brown, there are fine lines and wrinkles, and the folded surface is white.

It smells a little fishy, tastes slightly sour, and has the effect of tonifying the lungs and kidneys, stopping bleeding and reducing phlegm. Hope you find this helpful.
