Under, Chinese medicine flavin

Chapter 437 The end of the exam
Vice President Barto was not surprised that Li Yan could answer the question so perfectly.

Although, Huang Su, Li Yan, and Chen Jingshan never emphasized the relationship between the three at school.

Li Yan also changed the names of Huang Su and Chen Jingshan, and called them the same as her classmates.

But all the teaching staff in the school knew that Li Yan was Chen Jingshan's disciple.

Seeing that Huang Su and Chen Jingshan didn't speak for a long time, Vice President Barto also understood what they meant.

Facing such an exam like an interview, Huang Su and Chen Jingshan had to avoid suspicion a little bit.

"Well, just very solid."

Vice President Barto wrote down Li Yan's score for the first part while commenting.

Huang Su and Chen Jingshan also wrote down their scores.

As the first exam innovation, it is also a supervisor exam in the form of interview scoring.

In order to be more fair, the final score of the students is the method of subtracting the average score from three people.

This is also Chen Jingshan and Vice President Barto's protection of Huang Su, reducing the school's criticism of the exam.

Huang Su put down the gel pen in his hand: "Li Yan, you can go to the Chinese pharmacy to get Chinese medicine. You can only get it on the shelf, not in the medicine cabinet."

The name of the traditional Chinese medicine is written on the medicine cabinet, which loses the meaning of the exam.

Li Yan walked into the Chinese pharmacy with three prescriptions.

Li Yan didn't start to grab the medicine immediately, but asked instead: "Teacher, what is the standard for picking the medicine? Is it based on the best quality of traditional Chinese medicine, or the best cost-effective medicine?"

"This time is an exam, so naturally the quality of the medicinal materials shall prevail." Huang Su replied lightly.

This is also a loophole that Huang Su deliberately left for the students in Zhongjing class, just to see if these students really understood what he usually said.

It's not surprising that Li Yan can ask. It depends on whether the students behind can realize it.

Watching Li Yan walk into the traditional Chinese medicine room, Huang Su, Chen Jingshan, and Vice President Barto turned around and watched Li Yan's process of searching for, identifying and distinguishing medicines through the glass window.

Li Yan was very lucky, and found the medicinal material she wanted on the first shelf she selected.

In the middle of this shelf are all Rutaceae medicinal materials, including tangerine peel, green peel, aurantium husk, aurantium citrus, and citron.

There are two or three flavors of Chinese herbal medicines in Muxiang Shunqi Pills and Dingshen Toubu Soup.

There are several kinds of tangerine peel, green peel, aurantium husk, aurantium citrus, and citron on the shelves.

Among them, there are as many as six kinds of tangerine peel alone, some with great differences in quality and appearance, and some with little difference in quality and appearance.

Some people will say, isn't it just an orange peel, how can this thing be faked.

Hehe, everyone doesn't know how deep the water of tangerine peel is.

There is indeed no medicinal material added to the tangerine peel. After all, orange peel is the most common thing. There is no need to fake this thing. At most, ordinary tangerine peel is used as Xinhui tangerine peel, but the medicinal effect is the same.

Isn't the water of tangerine peel fake, but old.

Chenpi can range from three years to 28 years. Of course, the longer the age, the higher the price and the higher the medicinal value.

This gives unscrupulous Chinese medicine dealers room for profit.

As long as the freshly peeled orange peels are simply made old, the new orange peels can be sold for the price of ten years old orange peels. The huge profits here are beyond everyone's imagination.

There are various ways to make tangerine peel just to make it old.

Basically, it can be summarized into four categories, soaking and dyeing for aging, wet warehouse accumulation for aging, alternating dry and wet for aging, and high-temperature and high-humidity for aging.

The method of soaking and dyeing is to use Pu’er tea or some chemical drugs to water in proportion, and soak a large box of new leather for one or two years for more than ten seconds, then it can be dried in water, and the color of the inner capsule is like that of old leather in a wet warehouse. Same.

People with a good conscience will use Pu’er boiled water for dyeing, and those with a bad conscience will use chemical dyes. This kind of tangerine peel is not only useless, but also harmful to the body.

The old method of wet storage storage is to put the tangerine peel in a very humid place (such as the basement), where the temperature is high, the humidity is high, and there is no ventilation. One-year citrus fruits are made into five-year or ten-year tangerine peels, sorted to determine the year, such as 15, 20 or [-] years if the color is dark, and five years if the color is light.

Alternating wet and dry method is to put the orange peels in the basement first to accelerate the aging, and then transfer them to a dry place to dry and store. This cycle of operation can accelerate the aging and reduce the aging years.

In addition, store the tangerine peel in a place that is neither dry nor wet. When it is wet, it is drained and dried quickly with a dryer.

High-temperature and high-humidity aging method, using methods such as spraying, high temperature, spraying water or covering with wet cloth, wet sacks and other wet objects, so that the orange peel is in direct contact with the water, and the external moisture penetrates into the tissue to accelerate the aging process, and the dryer is dried .

Dyeing and high humidity and high temperature for aging, the production of aged tangerine peel is fast.

Li Yan didn't even look at the outermost bag of tangerine peels.

In this bag of tangerine peels, the outer skin and the inner flesh are almost the same color, both are black brown. At first glance, it looks like dyed tangerine peels. It is also the most unskilled old tangerine peels, and it is also the most harmful tangerine peels.

For the next few bags of tangerine peel, Li Yan would grab roughly the same shredded tangerine peel and weigh them with her hands.

Weighing is a commonly used method in traditional Chinese medicine when inspecting dried tangerine peels and wet tangerine peels.

Dry warehouse tangerine peel is the normal way to make tangerine peel.

Dry storage is to store Xinhui citrus peels in a dry and sealed environment with moderate temperature and humidity and ventilation. The tangerine peels are slowly fermented and aged under such natural conditions, so that the substances contained in them can be transformed naturally.Dried tangerine peel has a slow aging speed and slow color change, so Chinese herbalists and Chinese medicine call the real tangerine peel dry warehouse tangerine peel.

The tangerine peel is fermented and aged in a dry environment, the moisture of the tangerine peel itself will completely evaporate, and the texture is relatively light.

Dried tangerine peel is made in a humid environment, and there is a lot of water in the tangerine peel. If it is made by the old method of high temperature and high humidity, it is even heavier than fresh orange peel.

Li Yan was roughly sure that there were four bags of dried tangerine peel and two bags of dry tangerine peel.

In order to choose the last tangerine peel, Li Yan picked up several bags of tangerine peel and smelled them
The aroma of the other four bags of tangerine peel orange oil has different degrees of smoky taste, especially the smoky smell of the last bag even covers the original orange oil aroma of tangerine peel.

Only the third bag and the sixth bag smelled the fragrance of orange oil, which was definitely dried tangerine peel.

It’s just that the third bag of tangerine peel orange oil has a slight fruity sour taste, which should be infinitely close to the eight-year-old tangerine peel.

The sixth type of tangerine peel does not have the taste of fruit acid, but the aroma of orange oil is slightly mellow. This kind of tangerine peel has just passed ten years, but it will definitely not exceed three to five years.

Li Yan prayed in her heart, hoping that other students would not get the prescription with tangerine peel.

Otherwise, many people will deduct points for tangerine peel.

Li Yan decisively grabbed two small handfuls of tangerine peels that were more than ten years old, and put them in two plastic bags in batches.

"Smelling" is a common way to invigorate the spleen and tangerine peel. There are three flavors of tangerine peel: fragrant, old and mellow.

The smell of tangerine peel aged from three to five years is the aroma of orange oil with the residual acidity of orange peel. The sour taste of tangerine peel aged more than eight years will disappear, leaving only the aroma of orange oil.

The fragrance of tangerine peel orange oil that is more than ten years old will be more intense, with a mellow feeling.

As for the tangerine peel that is more than 20 years old, it has the time flavor of old medicinal materials in its mellowness, which is old.

As for the tangerine peel that is more than 30 years old, Li Yan has never seen it so far, and she doesn't know what it tastes like.

As for distinguishing the dry storage, wet storage and year of tangerine peel by smell, this is the sensitivity accumulated by Chinese medicine dealers who are very familiar with traditional Chinese medicine and years of experience in traditional Chinese medicine.

It is difficult for ordinary people to distinguish the year, but they can distinguish the dry warehouse from the wet warehouse.

For Xiaobai who has never been in contact with tangerine peel, there is also a very simple way to identify tangerine peel, which is to look at the inner capsule.

After long-term drying, fermentation and aging, the inner capsule will fall off automatically, and the texture is fresh and the oil chamber can be clearly seen. It is the dried orange peel. If there are thick white flocs and orange shreds on the inner capsule of the dried orange peel, it is the wet warehouse orange peel.

If you buy whole tangerine peels, you can also look at the stalks left by the orange peels. If the skin is dark in color but the stalks are still fresh, it must be wet tangerine peels. If the stalks are dry and shriveled, it is dry tangerine peels.

If you go to the Chinese herbal medicine market to buy it yourself, you can try it yourself. The tangerine peel in wet warehouse is as hard as wood and hard to bite, and it only has a faint smell of orange oil.

Dried tangerine peel is very easy to chew and leaves a strong aroma of orange oil in the mouth.

As people pay more attention to health preservation in traditional Chinese medicine, many medicinal materials with the same source of medicine and food have become the first choice for people to replace tea.

In particular, it is very common for tangerine peel to become a substitute for tea.

However, few people understand how to identify tangerine peel.

If you buy dyed tangerine peel and wet warehouse tangerine peel, the tangerine peel is not only useless, it can't play the role of health care, but it will cause harm to the body.

When you buy tangerine peel, you must keep your eyes open and learn how to distinguish tangerine peel.

After Li Yan identified the tangerine peel, she began to grab other medicinal materials.

Although, there are more than 60 herbs in Li Yan's three prescriptions.

However, due to Li Yan's proficiency in identifying medicinal materials, it only took more than 20 minutes to grasp the three medicinal materials.

Just because only the medicinal materials that have been learned will be packed in several bags of different qualities. Although there are many medicinal materials on the shelves of the Chinese pharmacy, they are still very obvious.

Li Yan carried plastic bags containing three pairs of medicinal materials and placed them on the table.

"Principal Chen, Principal Barto, and Teacher Huang! I've already picked up the three medicinal materials, please test them."

Chen Jingshan nodded and said, "That's right, it's much faster than I thought.

The three of them opened the quantity bag and began to check whether there were any medicinal materials caught by mistake, and inspected the quality of each medicinal material.

Soon, the three of them finished checking and began to score on their own.

Huang Su put down the gel pen: "Student Li Yan, your exam is over, let the next exam come in."

After Li Yan walked out, Vice President Barto turned to look at Huang Su and praised: "I have just finished half a semester of study. Not only can I accurately grasp the medicine, but I can also distinguish the quality of medicinal materials. Huang Su, your teaching effect is very good. "

"I saw the medicinal materials you purchased with my own eyes. Many Chinese medicine doctors may not be able to choose the best ones. Your students can actually choose the best medicinal materials among these medicinal materials. It is very remarkable."

In order to increase the difficulty, Huang Su bought not only fake and shoddy medicinal materials, good and bad medicinal materials, qualified medicinal materials, but also selected medicinal materials with less difference in quality among the high-quality medicinal materials.

Only in this way can we really check out the ability of the students in Zhongjing class to really distinguish medicinal materials.

Huang Su said modestly: "Li Yan has been studying Chinese medicine for three years. In order to learn to distinguish medicinal materials, I often take him to the medicinal materials during rest. She will let me down if she can't do it to the end. Look at the real results of the Zhongjing class, and you will know when you look at the next one."

When Li Yan walked out of the infirmary, she was surrounded by all the students.

"Swallow, how did you do in the exam?"

"Swallow, are the exam questions difficult?"

"Swallow, tell me about the content of the exam?"

Everyone surrounded Li Yan and began to ask about the content of the exam.

"Everyone be quiet!"

Li Yan yelled at the students who were chattering, and said simply: "Just like what the teacher just said, draw the prescription by yourself, tell the efficacy of the medicinal materials, and then go to grab the medicine. After the evaluation by the two principals and teachers, Scored together."

"It's just that it takes a lot of time to find medicines. Who would let there be hundreds of kinds of medicines in the Chinese pharmacy." Li Yan finally pointed out: "Don't worry, everyone, we will open several bags of medicinal materials at the same time. It is very easy to find, everyone only needs to pay attention to how many bags of the same medicinal material are opened, and it will definitely save time."

Li Yan told everyone all the experiences she could tell.

Seeing that the students got the information they wanted, they left Li Yan.

Li Yan looked at Jiang Bin: "Student Jiang Bin, it's your turn to go in."

Jiang Bin knocked on the door and walked in.

"Hello, Principal Chen! Hello, Principal Barto! Hello, Teacher!"

It was Huang Su who said, "Student Jiang Bin, don't be nervous, draw three notes!"

Jiang Bin reached out and stirred the box several times before pulling out three prescriptions.

Open the prescription, the first one says pinellia, tangerine peel, citrus aurantium, magnolia officinalis, divine comedy, malt, hawthorn, poria cocos, atractylodes atractylodes, and raw licorice.

The second one says medlar, dodder, raspberry, schisandra, leek, privet, mulberry, plantain, and jushengzi.

The third one says ginseng, Atractylodes macrocephala, angelica, Rehmannia glutinosa, Chuanxiong, white peony root, licorice, Ophiopogon japonicus, Schisandra chinensis, Morus alba, white poria cocos, donkey-hide gelatin.

Jiang Bin fumbled through all the medicinal materials in the three prescriptions, and began to recall the efficacy of all the medicinal materials in the prescriptions in his mind.

After waiting for Jiang Bin for 2 minutes, Huang Su asked, "Student Jiang Bin, are you ready?"

Jiang Bin said: "Both principals, teacher! I'm ready!"

"Student Jiang Bin, first show us the prescription you drew!"

After Huang Su's reminder, Jiang Bin suddenly realized, and quickly handed the prescription to Chen Jingshan.

The three of them glanced at the prescriptions and felt that Jiang Bin's luck was very good. There were not many medicinal ingredients in each prescription, but it was really difficult to distinguish between several herbs and find the best one.

The first prescription is Erchen Pingwei Decoction, the second prescription is Jiuzi Shengjing Pills, and the third prescription is Ningfei Decoction.

Huang Su returned the recipe to Jiang Bin: "Student Jiang Bin, you can start now!"
