Grandpa Yuan led the children to visit the mushroom greenhouse, and proposed: "Let's go, let's take a look at the herb greenhouse." ”

In the distance, there was a row of smaller greenhouses, and Yanyan was surprised: "Are these all herbs?" Aren't herbs used to make medicines? How to grow in a vegetable base? ”

Grandpa Yuan said: "In addition to being delicious and nutritious, most of the vegetables have more or less medicinal value, such as bitter gourd, purslane, leeks, fennel, carrots, ginger, etc., which have their own magical medicinal effects. In addition to being used as Chinese herbal medicine, many herbs can also be used as vegetables, such as ginseng, wolfberry, yellow essence, radix radix, Huoxiang, salvia, angelica, rhubarb, etc., if you can eat the herbs as vegetables, human physique can be enhanced a lot, but unfortunately it cannot be planted on a large scale, and go to the dining table of thousands of households. ”

Yeon-yeon was even more surprised and asked, "Huh? Can it still be like this? What Chinese herbs are grown here? ”

Kiki pointed to the signs in the greenhouse and said, "Look, those cards have names written on them!" ”

A few friends ran around and ran to a card and read the name out loud.

"This is ginseng, salvia."

"This is wolfberry, angelica."

"This is yellow essence, rhubarb."

"This is the root of the blue and the gastrodia."

"This is Panax notoginseng, Coptis chinensis."

"It's fritillary and herbaceous."

"This is Eucommia, He Shou Wu."

"Goji berries, aloe vera."

"Cordyceps sinensis~"

……

Yanyan saw the nameplate of aloe vera and said in surprise: "Grandpa Yuan, isn't aloe vera a flower and plant raised at home?" ”

"Aloe vera is native to the Mediterranean and Africa, and is popular among the public because it is easy to grow and is an ornamental plant with both flowers and leaves. According to research, there are more than 300 varieties of wild aloe vera, and there are only six edible varieties, and the main varieties of aloe vera with medicinal value are; Aloe vera, Curacao aloe vera, Cape of Good Hope aloe vera, Yuanjiang aloe vera, etc. Aloe vera is bitter, cold and non-toxic, and has bactericidal, anti-inflammatory, analgesic, sedative, detoxifying, immune and regenerative and anti-tumor, stomach diarrhea, heart and blood activation, as well as moisturizing beauty, anti-aging, and sunscreen effects. ”

Qiqi listened very carefully on the side, and once again burst out in amazement: "I didn't expect that aloe vera, which is usually used as an ornamental plant, is also a kind of Chinese medicinal material!" ”

Yanyan pointed to the nameplate of "Cordyceps" and asked, "Grandpa Yuan, can you tell us about Cordyceps?" How is it a worm and a grass? ”

When everyone heard this, they were also interested, and Kiki asked, "Yes~Yes~, is it a worm in winter, and it turns into grass in summer?" ”

"Hehe~ Cordyceps, also known as Chinese Cordyceps, is a traditional and precious Chinese medicinal material in Chinese history, which is parasitic on the bat moth larvae in the alpine meadow soil by the Cordyceps sinensis fungus of the Cordyceps serpentine family of the order Cordyceps spp., making the larvae's body ossified. Under suitable conditions, it is formed by the long rod-shaped sub-seat extracted from the head end of the zombie insect in summer, that is, the complex composed of the fruiting body of Cordyceps sinensis and the sclerotia (larval corpse) of the zombie fungus. Cordyceps sinensis is mainly produced in the alpine regions and snow-capped grasslands of Qinghai, Tibet, Sichuan, Yunnan, Gansu and Guizhou provinces and autonomous regions in Chinese mainland. ”

"So disgusting? How did you hear that it is still precious? ”

"Simply put, Cordyceps sinensis is a fungus, a special organism in which insects and fungi live in symbiosis. Cordyceps sinensis is a high-grade nourishing precious Chinese medicinal material, the history of folk application is earlier, "Materia Medica" has a record: "Cordyceps sinensis is the best produced in Jiading Mansion in Sichuan, followed by Yunnan and Guizhou." In the winter in the soil, the body is as alive as an old silkworm, and the hair can move, and in the summer, the hair comes out, and the body turns into grass'. He also said: 'Cordyceps sinensis has the ability to protect the lungs and kidneys, stop bleeding and reduce phlegm, and has a cough...... Just like the tonic bird's nest that is valued by the people'. ”

"Eh, if you can't see it, grind the powder and eat it~"

"I heard that Cordyceps sinensis is still authentic and fake?"

"Hmm~ Yes! Here, I'll ask the technician to take one out and talk to it. ”

Grandpa Yuan called the technician over and gave him an order. The technician brought a vial and a magnifying glass from the tray, and in the bottle was a yellow, dead, dead bug.

Binbin asked the two girls, "Aren't you afraid?" Disgusting no? ”

"Don't be afraid, if it's in a bottle, it's still dead! However, the thought of eating it...... It's disgusting! ”

Grandpa Yuan picked up the bottle, let everyone observe carefully, and said: "In terms of color, the genuine Cordyceps sinensis is divided into two parts: 'worm' and 'grass', the surface of the 'worm' body is dark yellow to light yellowish brown, and the color of most insects will change to a certain extent at the combination of insects and grass. The 'grass' part, the sub-base, is the color of a dead branch and has a darker color. The main thing is to look at the color change. ”

Everyone passed the vials one by one and looked at them carefully.

Kiki exclaimed, "It's really a bug! There are a lot of feet. ”

"Yes, in terms of appearance, there are 8 pairs of genuine Cordyceps sinensis on the ventral surface, and 4 pairs in the middle of the insect body are very obvious. The sub-seat emerges from the head of the worm's body, and the upper part is slightly enlarged. It can reach 4-7 cm in length and about 3 mm in diameter. Come, look again with a magnifying glass. ”

When the children observed with a magnifying glass, Grandpa Yuan continued: "Since Cordyceps sinensis is formed by parasitism of insects, and the essence is still insect corpses, so genuine Cordyceps sinensis has obvious lines after being broken, and there is a black core similar to "V" in the middle of Cordyceps, and some may also be a black spot, which is actually the digestive line of insects. There is also the smell, the genuine cordyceps sinensis has a slightly fishy smell of dry rotten insects and the aroma of grass mushrooms, which is the unique taste of cordyceps. According to the above 4 points, we can basically have a basic understanding of the authenticity of Cordyceps. ”

Qiqi's eyes widened and asked, "Grandpa Yuan, how do you eat cordyceps?" You can't really cook it and eat it, right? ”

"Haha~ Cordyceps sinensis is mainly used for medicine, and it can also be eaten directly. Boiling water as tea, instead of soaking it in boiling water, is simple and effective; Stewed with meat products, this method is the traditional cordyceps feast eating method; It is used to make medicinal wine and drink; 4. Use a grinder to grind Cordyceps sinensis into powder, put it in a capsule box and carry it with you, and take it regularly every day, but this method has hidden dangers in terms of hygiene, so you should pay attention to it. ”

Yeon-yeon wrinkled her nose and asked, "If it is better to make it into a medicine, what is its effect?" ”

"According to the analysis of medical science, Cordyceps contains cordyceps acid, which is suitable for the treatment of hemoptysis or blood in sputum and cough caused by lung qi deficiency, lung and kidney deficiency, tuberculosis, etc. Shortness of breath, night sweats, etc., also have a good effect on kidney deficiency, impotence, waist and knee pain, etc., and are also a good tonic for the elderly and infirm. In clinical practice, cordycepin is mostly used as an adjuvant treatment for malignant tumors, and the symptoms are improved in more than 91.7%; It is mainly used for patients with nose cancer, pharyngeal cancer, lung cancer, leukemia, brain cancer and other malignant tumors. Cordyceps acid is mostly used for cerebral edema, prevention and treatment of acute renal failure, regulating the heart, brain and blood vessels, promoting human metabolism, improving human microcirculation, lowering blood lipids and blood pressure. The pharmacological test of Cordyceps polysaccharides proved that Cordyceps polysaccharides have anti-tumor and anti-infectious disease effects, enhance sexual function, tonify the kidney and strengthen yang, benefit essence qi, prevent aging, and prolong life; It has a significant effect on chronic bronchitis and cor pulmonale in the elderly. It can improve the detoxification ability of the liver and play a role in supporting the liver. It is used to replenish blood and enhance the nutritional blood flow of the spleen in patients with hypoglycemic and hypolipidemic anemia. ”

"It's such a big use, no wonder it's very precious!" The little ones were amazed.

After the friends discussed the knowledge of cordyceps, they dispersed, and personally went to observe the herbs they were interested in.

Binbin saw Ding Xuecheng stop and stare in front of a greenhouse, and asked curiously: "Bobo, what are you looking at, so fascinated?" ”

"Ginseng."

"Wow, everyone, come and see, it's ginseng grown here!"

"Ginseng? I want to see! ”

"I also want to know, is ginseng grown like a turnip?"

"Binbin, tell us about ginseng, okay?"

"Okay~ I know something. Ginseng belongs to the Pentaceae family, which mainly grows in East Asia, especially in cold regions, and is known as 'Bang Mallet' in the northeast of China. Ginseng is a common medicinal herb in Asia, and American ginseng is also commonly used in North and Central America, and many herbal shops and supermarkets can find a variety of ginseng decoction pieces and extracts for health care products such as recovery after healing, enhancing physical strength, regulating hormones, lowering blood sugar and blood pressure, controlling liver index and liver function health. The saponins contained in the root of ginseng are its active ingredients, and the saponins in Changbai Mountain, China, are relatively high, but they are not easy to obtain, the price is high, and they are endangered species. ”

"What else?" Seeing that Binbin stopped talking, the two little girls hurriedly asked.

Bin Bin touched the back of his head and blushed. The two little girls looked at Ding Xuecheng again, which meant "you say"!

Ding Xuecheng stroked his forehead and said, "I also know a little." Ginseng is a relict plant of the Tertiary Period, belonging to the Pentaceae family, a perennial herbaceous plant with a stem height of about 40~50cm and a rotational palm-like compound leaf. In early summer, it blooms with small yellow-green flowers, the inflorescence at the top of the umbrella is single apical, and the fruit is oblate. It is also a precious Chinese medicinal material, one of the 'Three Treasures of Northeast China', and has a long history of medicinal use in China. For a long time, due to excessive mining and resource depletion, the forest ecological environment on which ginseng depends has been seriously damaged, so the Central Plains production areas represented by Shanxi Wujiake 'Shangdangshen', that is, the southern part of Shanxi, southern Hebei, Henan, western Shandong and other places have long been extinct. At present, Northeast ginseng is also on the verge of extinction, so it is of great significance to protect the natural resources of this species. ”

The two little girls listened with relish and continued to ask: "What kind of place does wild ginseng grow?" ”

"Ginseng is a plant of the family Panaxaceae, and it is a close relative of famous medicinal plants such as Panax notoginseng and American ginseng. Wild ginseng has high requirements for the growth environment, it is afraid of heat, drought, and sun, and requires loose and fertile soil, moist and cool air, so it grows mostly in the coniferous and broad-leaved mixed forests at an altitude of 500~1000 meters above sea level in Changbai Mountain. Ginseng blooms in July and August every year, and the purple-white flowers produce bright red berries. Wild ginseng grows very slowly in the deep mountains, and the roots of 60~100-year-old ginseng often weigh only a few tens of grams. ”

"It's artificially cultivated here, and I'm going to see how ginseng is grown."

"I also want to see what ginseng looks like, I don't know it when I meet it in the future, and it's a pity to miss it!"

Grandpa Yuan nodded with a smile and said, "Hehe, it's very interesting!" You're all very nice and well said. If you have any questions, you can ask the management technician here, and he will answer them for you. Everyone looked around, and after a quarter of an hour, we moved on to the second part. ”
