A small green notebook was taken out of Lu Xuan's pocket.

The pharmacy staff was obviously stunned the moment they saw the certificate, this thing was carried with them?

I'm afraid no one will carry it with them, right?

However, she didn't think much about it, took Lu Xuan's medical practitioner certificate and opened it to look at it, and after confirming that it was correct, she returned the certificate to Lu Xuan: "How many days does it take?" ”

"We only allow a maximum of half a month's supply."

"A week's worth will do."

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 arranged on the wall, and there are hundreds of small drawers on the cabinets, each of which has one or even three or four labels, and the label clearly writes the name of the Chinese medicine.

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

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

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

The seven pieces of yellow paper were neatly placed on the table, and after finding the gentian grass on the prescription, he immediately put it on the large plate on the side: "This is gentian grass, you can see it yourself." ”

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

And Lin Yongzhen and the others directly surrounded him, and after seeing it, he asked curiously: "Xiao Xuan, isn't this Chinese medicine all the same?" Can you still see the good from the bad? ”

This question is not only Lin Yongzhen's doubts, but even Ji Xiuwen, who studies Chinese medicine, is also a little curious.

There are too many ways and means to distinguish traditional Chinese medicine, even if you are studying traditional Chinese medicine, you dare not say that it is all clear.

Moreover, generally speaking, those who do not specialize in Chinese medicine basically have few opportunities to contact Chinese medicine, and when they are in school, they may still be exposed to some of them, and after graduation, after entering the hospital, there are fewer opportunities to contact Chinese medicine.

Like Ji Xiuwen, who graduated and grabbed medicine in a Chinese medicine pharmacy, it is a little better, and some people who go directly to the doctor as assistants may not have touched Chinese medicine after graduation.

In traditional Chinese medicine hospitals, there are corresponding suppliers for the procurement of traditional Chinese medicine, which has nothing to do with the doctors themselves.

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

Even the chief physician, or even the leaders of the hospital, these people who have the right to make decisions may not necessarily personally inspect the quality of traditional Chinese medicine.

This ability to judge the quality of Chinese medicine is naturally not something that every Chinese medicine practitioner has.

This is very different from ancient times.

In ancient times, most of the time, Chinese medicine was picked and even processed by the Chinese medicine practitioner himself, and it was clear how good the medicinal materials were.

"I can see it."

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

This is a kind of cold, bitter taste, with the effect of diarrhea liver and gallbladder fire, remove scorching dampness and heat, often used in the treatment of liver meridian heat, epilepsy mania, headache, sore throat, jaundice, hot dysentery, carbuncle swelling and sores, scrotal swelling and pain, genital itching and other symptoms, can also be combined with other drugs, treatment of Japanese encephalitis, for the liver and gallbladder heat commonly used Chinese medicine.

It grows on hillside grasses, shrubs and tree edges, and can be harvested in spring and autumn every year, but this gentian grass is best harvested in autumn.

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

However, there are really many counterfeit medicines, such as the dried roots of the herb Clematis of the Radix Ginseng family, commonly known as grass gentian, which used to be gentian grass. ”

Ji Xiuwen took a closer look and asked, "If you really encounter it, how can you tell the truth from the fake?" I've seen a clematis, it's really similar to gentian, if you don't look carefully, you can't identify it at all, this is still I spent a while in the Chinese medicine pharmacy, otherwise I really don't know that gentian and clematis are so similar. ”

"Look ......"

Lu Xuan pointed to the gentian grass in his hand, "The real gentian grass, the dry roots are irregular blocks, generally about 0.5-3 cm long, about 0.5-1 cm in diameter, the surface is dark gray-brown or dark brown, wrinkled, with horizontal stripes, the upper end has stem marks or residual stem bases;

Of course, it can also be further identified by the method of smelling, the smell of gentian grass is weak, and the taste is extremely bitter. ”

According to 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 the false gentian grass are also irregular blocks, the upper end can be seen with sunken stem marks, which is a relatively obvious feature."

Lu Xuan said: "And the roots of false gentian grass grow on the rhizome, cylindrical, 2-8 cm long, 0.1-0.2 cm in diameter, the surface is tan, flat or slightly wrinkled, and it is also brittle, easy to break, but the skin of the section is brown, and the wood is yellow-white; the smell is slightly fragrant, and the taste is bitter, but it is not as bitter as the real gentian." ”

"Of course, it's not just the herbs of the Scrophularia family that can be confused with the fake, there is also a medicinal herb that is similar to gentian grass."

"What medicine?"

"Peach Seven."

"Peach Seven?"

Ji Xiuwen's face was full of doubts, he really hadn't heard of this.

Lu Xuan explained with a smile: "Peach Seven is the root of the ghost white plant of the Xiaole family, and unlike Gentian grass, Peach Seven is poisonous, and its effect is different from that of gentian. Moreover, its rhizome is irregular and blocky, and a concave stem scar can be seen at the upper end. At the lower end of the rhizome and around the roots, there are many slender roots, cylindrical, 6-12 cm long, 2-3 mm in diameter, the surface is tan, flat or slightly longitudinally wrinkled, the section is powdery, white, the wood is yellow, and the taste is bitter.

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

"This guy really has some skills!"

The staff who were grabbing the medicine originally thought that Lu Xuan wanted to see Chinese medicine just casually, but he didn't expect Lu Xuan to know so much, not only knowing gentian grass, but even knowing the properties of several traditional Chinese medicines that counterfeit gentian grass knew clearly.

This guy is amazing!

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

"Gentian is okay, right?" She looked at Lu Xuan and asked.

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

Can you even see the harvest season?

The staff's eyes instantly widened like copper bells, and they looked at Lu Xuan in disbelief.

It's not just her, at this moment, even Ji Xiuwen couldn't believe it.

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

Lu Xuan said with a smile: "Generally speaking, the gentian grass harvested in spring is mainly dried, after all, the humidity is higher in spring, and because it is dry in autumn, it is often dried in the shade, and it is not difficult to make a judgment based on this, but now that science and technology are becoming more and more developed, it is possible to dry when it is harvested, and it is more difficult to judge at this time." ”

Hearing this, Ji Xiuwen and the others didn't say anything, but the eyes of the staff who grabbed the medicine lit up a little.

I have seen it for a long time.

I didn't expect that there was so much attention to identifying Chinese medicine.

The key is that she knows that there is no problem at all with what Lu Xuan said, this gentian grass is indeed dried, not shaded, and she has glanced at the label on it before, it is really harvested in spring.

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

Although they look young, their skills are not bad at all.

Regardless of medical skills, this ability to identify medicinal materials is rare in the whole country.

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

This may not be too high in a big city, but you must know that the average salary in Anjiang County is only one or two thousand, and tens of thousands of people in Anjiang County can beat 99.9999 percent of the people in Anjiang County.

At this moment, she had no intention of watching the play, so she put Yin Chen in front of Lu Xuan and whispered: "This is Yin Chen, take a look, if you have any questions, just say it." ”

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

It's not a high-quality medicinal material, after all, high-quality medicinal materials often mean high prices, in the small county town of Anjiang, there are not many people who catch traditional Chinese medicine, and this is less than the entire Anjiang county on this one, otherwise the purchased traditional Chinese medicine is afraid that it will have to be put in the medicine cabinet with worms and mold.

As for whether there are fake drugs, she doesn't know, and it's hard to say.

It's just that after knowing that Lu Xuan is so capable, he also has a little drum in his heart.

"There shouldn't be any counterfeit medicines, right?"

With this in mind, she shifted her steps to find the third herb.

Lu Xuan, on the other hand, took a little Yin Chen in his hand and said with a smile: "This is Yin Chen, which is usually used in traditional Chinese medicine hospitals, and it is a relatively common and commonly used Chinese herbal medicine." ”

Ji Xiuwen nodded, he had been in the Chinese medicine pharmacy for half a year before, and he knew that many of the prescriptions prescribed by those doctors had Yin Chen, and after seeing a lot, he naturally knew that this was Yin Chen.

Although the quality of the Chinese herbal medicines purchased by the Chinese medicine hospital is not excellent, it can also be free of fakes.

"There are two kinds of Yin Chen, one is the Mian Yin Chen harvested in the spring, and the other is the Hua Yin Chen harvested in the autumn." Lu Xuan introduced again.

"There should be a difference between these two kinds of Yin Chen, right?" Ji Xiuwen asked.

"Of course there is a difference."

Lu Xuan didn't think much about it, so he said: "Like what I am holding in my hand is Mianyin Chen, Mianyin Chen, which was first seen in the book "Benjing Fengyuan" written by Zhang Lu in the Qing Dynasty.

"There are two kinds of Yin Chen: one with leaves as thin as Artemisia annua, named Mian Yin Chen, specializing in water, and is a medicine for damp heat and yellow scab.

A kind of child such as a bell, the name of the mountain Yin Chen, also known as horn artemisia, its taste is bitter and small poisonous, specializing in killing insects, treating mouth and tooth sores is absolutely victorious, and entering the sun.

The main diseases of rheumatism, cold and heat, heat and yellow fever, and dampness and Yangming all refer to Mianyin Chen. ”

The Mianyin Chen mentioned by Zhang Lu actually refers to the matrix of ancient medicinal Yinchen, Artemisia and Artemisia inchen.

In addition, Zhang Lu also mentioned Shanyinchen, Shanyinchen was first seen in Rihuazi's "Rihuazi Materia Medica" during the Five Dynasties: "Shiyinchen, bitter, cool, non-toxic...... It is also known as Yin Chen Artemisia and Mountain Yin Chen. There are all in this and the state and the South Mountain and the ridge. ”

The Shi Yin Chen, Yin Chen Artemisia and Mountain Yin Chen mentioned by Mr. Rihuazi are actually the substrates of ancient medicinal Yin Chen, but they should all be wild Yin Chen, not mostly planted now. ”

Ji Xiuwen nodded, according to the records of ancient medical techniques, it is not surprising that most of them are wild, after all, there was no planting at that time, even if some traditional Chinese medicines were planted, but the scale of cultivation was not large.

Moreover, the effects of wild medicines are not comparable to those cultivated in the wild.

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

Just like ginseng, the value of wild ginseng is not a little higher than that of grown ginseng.

Both seem to have the same ingredients, but in terms of curing diseases and saving people, there is a world of difference.

Ginseng that is old enough has the effect of hanging life, but it is difficult to say if it is planted.

"Is there any difference between the Yin Chen we use now and the one you just mentioned?" The staff who ran to grab the medicine asked curiously.

She had been paying attention to this side, and when she saw that no one was talking, she couldn't suppress the curiosity in her heart, thought about it, gritted her teeth and asked.

Lu Xuan raised his head and saw that the other party was looking at this side expectantly, and seeing that several people were very interested in knowing medicine, he thought about it and said: "Speaking of this, I have to mention the 2015 edition of the "Pharmacopoeia".

The medicinal substrate source is Artemisia annua and Artemisia sinensis due to different picking times, the harvest in spring is called "Mianyinchen", and the harvest in autumn is called "Huayinchen".

It can be seen that the meaning of today's Mianyin Chen is different from that contained in Zhang Lu in the Qing Dynasty.

However, such a substrate source will inevitably involve a problem, due to the different picking time, the maturity of the plant is different, its effective content is naturally different, and the effect is naturally different.

For example, "Materia Medica" says: "Green peel, tangerine peel, citrus aurantium, citrus aurantium, because it is harvested sooner or later, it is especially old and tender and famous." ”

Pharmacological studies also showed that the main components of Mianyinchen were volatile oils and chlorogenic acids, and its choleretic and anti-pathogenic microbial effects were significantly better than those of Huayinchen, and the main components of Huayinchen were coumarin compounds and flavonoids, which had good anti-inflammatory, hepatoprotective and analgesic effects.

If so, Mianyin Chen and Huayin Chen should also be used differently.

Both are Yin Chen, but the utility is different, when you use it, it will naturally be divided into two kinds, you are grasping Mian Yin Chen, and what I need is Hua Yin Chen. ”

After speaking, he smiled slightly.

"Hua Yin Chen ......"

After muttering, the staff looked at the medicine cabinet again: "I seem to see that there are two kinds, I'll look for them." ”

She put down the knotweed, put away the Mianyin Chen she had grasped before, found Hua Yinchen in the same chest of drawers, and said with a smile: "This should be Hua Yinchen, right?" ”

Lu Xuan glanced up, and after confirming it, he nodded and said, "This is it." ”

"You are so amazing, you are so young and know so much about Chinese medicine, and those who don't know think you are specialized in this business." The staff weighed Hua Yin Chen into two and put them on yellow paper.

"I learned Chinese medicine, so I know more or less." Lu Xuan said modestly.

"It's not like you know something."
