I can hear the voice of Chinese medicine

Chapter 208
Lu Xuan took out a small green notebook from his pocket.

The pharmacy staff was obviously stunned when they saw the certificate. Do you carry this thing with you?

I'm afraid no one will take it with them, right?
However, she didn't think much about it. She took Lu Xuan's medical practitioner certificate and opened it and took a look at it. After confirming that it was correct, she returned the certificate to Lu Xuan: "How many days will it be required?"

“We only allow half a month’s supply at most.”

"Just one week is fine."

The staff nodded and came to the left side of the pharmacy under Lu Xuan's gaze.

A row of Chinese medicine cabinets are neatly placed against the wall. There are hundreds of small drawers on the cabinets. Each drawer has one or even three or four labels with the name of the Chinese medicine clearly written on the label.

As the staff walked over, the four of them, Lu Xuan, also leaned over.

While she was still checking the prescription, Lu Xuan reminded: "Can you show me the medicine before packaging it separately?"

The staff member looked up, narrowed his eyes slightly, and then nodded.

Place seven pieces of yellow paper neatly on the table. After finding the gentian on the prescription, he immediately placed it on the big plate aside: "This is gentian. Take a look at it yourself."

After she finished speaking, she went to find the second medicine.

Lin Yongzhen and others gathered around them. After looking at them, they asked curiously: "Xiaoxuan, aren't all these Chinese medicines the same? Can you tell whether they are good or bad?"

This question is not only confusing to Lin Yongzhen, but also Ji Xiuwen, who studies Chinese medicine, is also a little curious.

There are too many ways to identify traditional Chinese medicine, and even those who study traditional Chinese medicine cannot say that they are all clear.

Moreover, generally speaking, those who do not specialize in Chinese medicine basically have few opportunities to come into contact with Chinese medicine. When they are in school, they may come into contact with some from time to time. After graduation and entering the hospital, there are fewer opportunities to come into contact with Chinese medicine. .

Those like Ji Xiuwen who graduate and work in traditional Chinese medicine pharmacies are better off. Some who go directly to work as assistants to doctors may not have ever touched traditional Chinese medicine after graduation.

As for traditional Chinese medicine hospitals, the procurement of traditional Chinese medicines generally has corresponding suppliers and has nothing to do with the doctors themselves.

Whether it's good or bad, it's not something a little doctor can decide.

Even chief physicians and even hospital leaders, who have the power to make decisions, may not personally inspect the quality of traditional Chinese medicines.

Naturally, not every Chinese medicine practitioner has the ability to judge whether Chinese medicine is good or bad.

This is very different from ancient times.

In ancient times, most of the time, Chinese medicines were picked and even processed by Chinese medicine practitioners themselves, and the quality of the medicinal materials was clearly known.

"Of course you can tell."

Lu Xuan took a gentian plant and introduced: "Gentian grass, also known as ground gall grass and mountain gentian, is the root and rhizome of Gentianaceae plant Gentianaceae or Gentian three-flowered plants.

This is a traditional Chinese medicine that is cold in nature and bitter in taste, and has the effect of purging excess fire in the liver and gallbladder and removing damp heat in the lower burner. It is often used to treat excess heat in the liver meridian, epilepsy and mania, headache, red eyes, sore throat, jaundice, heat dysentery, and carbuncle. It can also be used in combination with other drugs to treat sores, scrotal swelling and pain, and vaginal itching. It is a commonly used traditional Chinese medicine for clearing excess heat in the liver and gallbladder.

It often grows in hillside grass, shrubs and forest edges. It can be harvested in spring and autumn every year, but the quality of this gentian is best when harvested in autumn.

After digging, remove the stems and leaves, wash and dry them before use as medicine.

However, there are many counterfeits of this medicine. For example, in the past, the dried roots of the Scrophulariaceae plant Clematis, commonly known as Gentian grass, were used as gentian. "

Ji Xiuwen took a closer look and asked: "If you really encounter it, how can you tell the authenticity from the fake? I have seen Clematis, and it is indeed very similar to Gentian. If you don't look carefully, you can't identify it at all. This is what I am doing I’ve been in a traditional Chinese medicine dispensary for a while, otherwise I wouldn’t have known that gentian and clematis are so similar.”

"look……"

Lu Xuan pointed to the gentian in his hand, "Real gentian, the dried roots are in the shape of irregular lumps, generally about 0.5-3 cm long and 0.5-1 cm in diameter, with a dark gray-brown or dark brown surface. Wrinkled, with horizontal lines, stem marks or residual stem base at the upper end; brittle, easy to break, slightly flat cross section, yellowish brown, very small, off-white wood.

Of course, you can further identify it by smelling it. Gentian grass smells weak and tastes extremely bitter. "

Following Lu Xuan's introduction, Ji Xiuwen looked at it carefully for a while and found that it was almost exactly the same as what Lu Xuan said.

He just hadn't tasted it, and he didn't know what it tasted like.

"What about the fake gentian?" Ji Xiuwen asked again.

"Although the roots of false gentian are also in irregular lumps, there are sunken stem marks on the upper end, which is a more obvious feature."

Lu Xuan said: "Furthermore, false gentian roots grow in clusters on the rhizomes. They are cylindrical, 2-8 cm long and 0.1-0.2 cm in diameter. The surface is tan, flat or slightly wrinkled; they are also brittle and easy to break, but the cross-section of the skin is It is brown in color, with yellowish-white wood; it smells slightly fragrant and tastes bitter, but not as bitter as the real gentian."

“Of course, it’s not just the Scrophulariaceae plants that can be mistaken for the real ones, there is also a medicinal herb that looks similar to gentian.”

"What medicine?"

"Tao'er Qi."

"Tao'er Qi?"

Ji Xiuwen's face was full of doubts. He had never heard of this.

Lu Xuan explained with a smile: "Tao'erqi is the root of the small plant "Ghost White". Different from gentian, Tao'erqi is poisonous and its effect is different from that of gentian. Moreover, its rhizome is irregular and massive. A depressed stem mark can be seen at the upper end. There are many slender roots at the lower end of the rhizome and around it. The root is cylindrical, 6-12cm long, 2-3mm in diameter, with a tan surface, flat or slightly longitudinal wrinkles, and a pinkish white cross-section. , xylem yellow, bitter taste.

But like other fake gentian, although it is bitter, it is not as bitter as gentian. "

"This guy is really capable!"

The staff who were picking up the medicine originally thought that Lu Xuan was just talking casually if he wanted to take a look at the traditional Chinese medicine. Unexpectedly, Lu Xuan actually knew so much, not only about gentian grass, but also about the properties of several traditional Chinese medicines that were fake gentian grass. We all know it clearly.

This guy is amazing!

She was a little surprised and put Yinchen in front of Lu Xuan, wanting to see if this guy was really that powerful.

"Is the gentian okay?" She looked at Lu Xuan and asked.

Lu Xuan put down the gentian in his hand and shook his head: "It's not a big problem, but it should be harvested in spring. It is not as effective as the one harvested in autumn, but the quality of the medicine is still good. "

Can you even tell the harvest season?
The staff's eyes instantly widened like bells, looking at Lu Xuan in disbelief.

Not only her, but even Ji Xiuwen couldn't believe it at this moment.

"No, Lu Xuan, you can even tell the harvest season? How is this possible?"

Lu Xuan said with a smile: "Generally speaking, gentians harvested in spring are mainly dried. After all, the humidity in spring is high, and autumn is dry, so it is common to dry it in the shade. Based on this, we make a judgment and It’s not difficult, but now that science and technology are becoming more and more advanced, what is harvested may be dried at any time, so it is more difficult to judge at this time.”

Hearing this, Ji Xiuwen and others didn't say anything, but the eyes of the staff who took the medicine were a little bright.Learned a lot.

I didn’t expect that there is so much to pay attention to in identifying Chinese medicine.

The key is that she knows that there is nothing wrong with what Lu Xuan said. The gentian is indeed dried, not shade-dried, and the label inside, which she had taken a look at before, shows that it is really harvested in spring.

At this moment, she didn't dare to underestimate Lu Xuan at all.

Although he looks young, his skills are not bad at all.

No matter how good his medical skills are, his ability to identify medicinal materials is rare in the country.

To put it bluntly, as long as Lu Xuan is willing to stay directly in Hui'an Pharmacy, the boss in this small county can offer a salary of tens of thousands a month.

This may not be too high in a big city, but you have to know that the average salary in Anjiang County is only one or two thousand, and tens of thousands can beat 90.00% of the people in Anjiang County.

At this moment, she no longer had any intention of watching the show. She placed the yinchen in front of Lu Xuan and whispered: "This is yinchen. Take a look at it and ask if you have any questions."

To be honest, she didn't know if there was anything wrong with the Chinese medicine purchased by the pharmacy.

It’s not high-quality medicinal materials, that’s for sure. After all, high-quality medicinal materials often mean high prices. In the small county of Anjiang, there are not many people who practice traditional Chinese medicine. This is even less than this one in the entire Anjiang county. Otherwise, purchasing I'm afraid the traditional Chinese medicine will have to be kept in the medicine cabinet where insects will grow and mold.

As for whether there were fake medicines, she didn't know and couldn't tell.

Just knowing that Lu Xuan was so capable made me feel a little nervous.

"There shouldn't be any fake medicine, right?"

With this thought in mind, she moved to find the third medicine.

Lu Xuan, on the other hand, took some wormwood in his hand and said with a smile: "This is wormwood. It is often used in traditional Chinese medicine hospitals. It is a relatively common and commonly used Chinese medicinal material."

Ji Xiuwen nodded. He had stayed in a Chinese medicine pharmacy for half a year before and knew that many of the medicines prescribed by doctors contained artemisia. He had seen it many times and naturally knew that this was artemisia.

Although the quality of the Chinese medicinal materials purchased by traditional Chinese medicine hospitals is not of the highest quality, there are no fakes.

"As for artemisia, there are two types, one is the cotton wormwood harvested in spring, and the other is the flower wormwood harvested in autumn." Lu Xuan introduced again.

"There should be a difference between these two types of wormwood, right?" Ji Xiuwen asked.

"Of course there are differences."

Lu Xuan didn't think much and said, "What I'm holding in my hand is Mian Yin Chen. Mian Yin Chen first appeared in the book "Ben Jing Feng Yuan" written by Zhang Lu in the Qing Dynasty.

"There are two kinds of Yinchen: one with leaves as thin as artemisia annua, named Mian Yinchen, which specializes in diuresis and is an important medicine for damp-heat and jaundice.

A kind of plant that gives birth to children like a bell is named Mountain Yinchen, also known as Cornwort. Its taste is pungent and slightly poisonous. It is specialized in killing insects and is excellent in treating oral ulcers. It is combined with Foot Taiyang.

"Ben Jing" mainly refers to diseases caused by rheumatism, cold and heat, heat knots, jaundice, dampness and Yangming, which all refer to Yinchen. "

What Zhang Lu talks about actually refers to Artemisia wormwood and Artemisia wormwood, the substrates of ancient medicinal wormwood.

In addition, Zhang Lu also mentioned Yinchen, which first appeared in "Rihuazi Materia Medica" written by Rihuazi during the Five Dynasties: "Yinchen has a bitter taste, is cool, and is non-toxic... It is also known as Artemisia wormwood and Mountain wormwood. Yinchen. It originates from Hezhou and can be found in Nanshan and Lingshang."

The stone mugwort, mugwort and mugwort mentioned by Mr. Rikako are actually the bases of mugwort and mugwort used in ancient times. However, they should all be wild, rather than cultivated nowadays. "

Ji Xiuwen nodded. Not surprisingly, most of what was recorded in ancient medical techniques was wild. After all, there was no cultivation at that time. Even if some Chinese medicines were cultivated, the scale of cultivation was not large.

Moreover, the effect of wild medicines is not comparable to that of cultivated ones.

There is no doubt that the wild effect is better than the cultivated one.

Just like ginseng, the value of wild ginseng is higher than that of cultivated ginseng, not 01:30 points.

Both seem to have the same ingredients, but they are completely different in terms of treating diseases and saving lives.

Ginseng that is old enough can have life-threatening effects, but it's hard to tell if it's grown.

"Is there any difference between the wormwood we are using now and the ones you just mentioned?" the staff member who ran to grab the medicine asked curiously.

She had been paying attention here and saw that no one was speaking, but she couldn't suppress the curiosity in her heart. After thinking about it, she gritted her teeth and asked.

Lu Xuan raised his head and saw that the other party was looking here expectantly, and seeing that several people were very interested in identifying medicines, he thought for a while and said: "Speaking of this, I have to mention the 2015 edition. "Pharmacopoeia" records.

The sources of medicinal wormwood substrates are Artemisia cordata and Artemisia wormwood, which are divided into two types due to different harvesting times. The ones harvested in spring are called "Mian Yinchen", while the ones harvested in autumn are called "Hua Yinchen".

It can be seen that the meaning of today's Mian Yin Chen is different from that of Mian Yin Chen recorded by Zhang Lu in the Qing Dynasty.

However, such a substrate source inevitably involves a problem. Due to different picking times and different maturity levels of the plants, their effective contents are naturally different, and their effects are naturally different.

For example, "Materia Medica Mengquan" says: "One kind is green peel and tangerine peel, and the other is Fructus Aurantii and Fructus Aurantii. They are named because they are harvested sooner or later and are particularly old and tender."

Pharmacological studies also suggest that the main components of Yinchen are volatile oils and chlorogenic acid and other compounds, and its choleretic and anti-pathogenic microbial effects are significantly better than those of Yinchen. The main components of Yinchen are coumarin compounds and flavonoids. Compounds with good anti-inflammatory, hepatoprotective and analgesic effects.

If so, Mian Yin Chen and Hua Yin Chen should be used differently.

Both are wormwood, but their effects are different. When using them, they are naturally divided into two types. What you are grabbing is wormwood, while what I need is flower wormwood. "

After speaking, he smiled slightly.

"Hua Yin Chen..."

After murmuring, the staff member looked at the medicine cabinet again: "I think there are two kinds. Let me look for it."

She put down the knotweed, put away the flower wormwood she had grabbed earlier, found the flower wormwood in the same drawer, and said with a smile, "This should be the flower wormwood, right?"

Lu Xuan raised his head and glanced at it. After confirming it, he nodded and said, "That's it."

"You are so amazing. You know so much about Chinese medicine at such a young age. People who don't know would think you specialize in this field." The staff weighed the flowers and put them on yellow paper.

"I studied Chinese medicine, so I know more or less about it." Lu Xuan said modestly.

"This is not knowing something."
