Blair?"

"Blair is here too?"

"He's the damn Blair!"

"Damn, he's the one who invented the superfluous thing like a stethoscope!"

......

As soon as Catherine's words fell, Chen Luo and Christine did not speak, and the surroundings were like a fried pot, instantly boiling, and the atmosphere was even more enthusiastic than the discussion of the plague just now.

At the same time, Chen Luo also felt a deep resentment from the people around him.

However, he was seen as a devil and a symbol of evil in the mathematical world, and he was used to being hated for a long time.

Chen Luo ignored everyone, but looked at Catherine and asked, "Doctor Catherine, have you found out what disease caused the plague?"

Catherine shook her head and said, "Not yet, Wang Du has never had this disease, and the doctors don't know what kind of potion to prepare." ”

"What kind of symptoms do patients have?" It is not easy for doctors in this world to diagnose the condition, so Chen Luo changed his question.

Catherine looked at him and said, "The patient sweats profusely, has a headache, is thirsty, often has intermittent chills or fever......"

Chen Luo asked, "Is the interval between the two seizures exactly about two days?"

Catherine was stunned for a moment, looked at him, and said in surprise: "How do you know?"

This conclusion was discovered by several doctors just now, and the patient was generally normal between episodes, but each episode, he was immediately in danger and even died......

Chen Luo muttered, "Malaria ......"

He was not a doctor, but he had heard of the notoriety of malaria.

Malaria, AIDS, tuberculosis, and known as the world's three major diseases, malaria, an intermittent febrile disease, is known as the "murderer of millions of people", if the impact of malaria is assessed according to the number of victims and the degree of victimization, then it can be called the most devastating disease in human history.

Throughout the 17th century, malaria raged around the world and nearly killed Kangxi, and even in the 19th century, it was still a common disease on the European continent.

After entering the 21st century, nearly 300 million people in the world are infected with malaria every year, and 1 million people die as a result.

Catherine looked at Chen Luo in confusion and asked, "What?"

Chen Luo came back to his senses and said in a low voice, "I may have a cure for this plague. ”

When Catherine heard this, her face showed joy, and she grabbed his hand excitedly and asked, "Toni Blair, is this true?"

Chen Luo nodded and said, "I read in a book before that some people called this disease "malaria", and they successfully cured many patients. ”

Catherine hurriedly said, "Where is that book now?"

Chen Luo shook his head and said, "I lost it when I moved later, but I still remember the two medicines for treating malaria, provided that we can find the raw materials......"

While the medical association and other doctors were still debating what method to take to treat this plague, Chen Luo and Catherine and Christine had already arrived in a quiet room.

Christine closed the door, Catherine looked at Chen Luo, and asked urgently, "What materials do you need to make that kind of potion?"

The discovery of quinine as a cure for malaria was one of the greatest achievements of 17th-century medicine.

The reason why Chen Luo understands this knowledge is because Tu Youyou's team discovered artemisinin, solved the problem of failure of antimalarial treatment, won the Nobel Prize in physiology or medicine, and stood on the Nobel Prize podium as a Chinese, making the domestic mainstream non-mainstream media scramble to report, Chen Luo, who is in college, is also one of the countless young people who are proud of Chinese scientists.

For this reason, he specially learned about malaria on the Internet, and also knew that before artemisinin, quinine was the best specific drug for treating malaria.

It's just that the cinchona tree used to produce quinine is native to South America, and it is not found everywhere, and Chen Luo doesn't know if this kind of tree exists in the Divine Grace Continent.

Chen Luo looked at Catherine and said, "That's a kind of tree, I don't know what the name of the tree is, I only know that its bark is grayish-brown, thin, with shallow and many cracks, the corolla is white or light yellowish white, and the inner edge has pale yellow pubescence ......"

Catherine looked at Chen Luo and said confusedly, "I know a lot of plants, but I have never heard of this kind of tree. ”

Chen Luo sighed, plants that even Catherine didn't know were not necessarily absent in this world, but there were certainly no near the royal capital, and the road to treat malaria through quinine was temporarily blocked.

In addition to quinine, Chen Luo knew that the only one that could treat malaria was artemisinin.

Artemisia annua is widely distributed and grows in temperate, cold and subtropical regions of Europe and Asia, Chen Luo rarely goes out, and has not seen it in the Luolan Kingdom, which does not mean that it does not exist.

Chen Luo looked at Catherine again and said, "There is also a plant that is more than one person tall, and the plant has a strong volatile aroma. Roots vertical, narrowly spindle-shaped, stems may grow to adult height, longitudinally ridged, green when young, brown or reddish-brown later, multi-branched......"

Before Chen Luo finished speaking, Catherine blurted out and said, "Herb!"

She took out thick books from the bookshelf in the corner, flipped through them for a while, pointed to one of them, and asked, "Is this what Blair said?"

Chen Luo recognized it at a glance, and the thing named "Herb" in the book was Artemisia annua.

He breathed a sigh of relief and nodded, "This is it." ”

"How?" Catherine continued, "mash it up for juice and give it to the patient?"

Chen Luo shook his head and said, "Taking it directly doesn't have much effect, you need to extract the active ingredients in it." ”

Catherine asked, "How?"

Chen Luo thought for a while and said: "First of all, you need to prepare some alcohol with high purity, and then you need to prepare some ether with alcohol, and first prepare a large amount of vanilla grass, how to extract it, and then talk about it......"

For most people, high school is the pinnacle of wisdom in their lives.

Back then, Chen Luo also knew the operating principle of celestial bodies, and the organic and inorganic reactions; he solved the elliptic hyperbola in front and drew the cellular biosphere in the back; he could speak English, he could also translate ancient Chinese, he could find the number series, he could speak Ma Zhe, he could memorize the table of chemical elements, and he could understand the physical circuit diagram......

After going to university, except for the knowledge of his major, he was almost illiterate.

Now that he has forgotten most of these things, the remaining knowledge, the artemisinin extracted, although it is better than directly pounding the juice, but the purity will not be very high.

But what Chen Luo can't do doesn't mean Catherine can't do it.

Wizards have no better understanding of plants than magicians, and they can even use witchcraft to extract some of the components of plants out of thin air, which is mentioned in Heril's Codex, but he does not record the specific method.

Catherine was obviously not worried about purification, and Christine said, "I'll have someone prepare a lot of vanilla at once!"

Christine quickly arranged it, and Chen Luo finally relieved his heart, he didn't want malaria to be raging in the royal capital, let alone not save Alice.

After the tense atmosphere was lifted, Chen Luo suddenly found that Christine was looking at him with a suspicious look.

Chen Luo asked, "Is there anything else going on with Her Royal Highness the Princess?"

Christine said, "Call me Mr. Christine." ”

“...... Good. Chen Luo looked at her and asked again, "Is there anything else I want to ask Mr. Christine?"

Christine clasped her hands, looked at Chen Luo, and asked, "You said, these are what you saw from a book, what is the name of that book, and what else is written on it?"

This kind of reason really can't be hidden from Christine, as a princess, she is well-informed, and if Chen Luo makes it up, it is very likely that she will be exposed.

He smiled embarrassedly and said, "Sure enough, I still can't hide it from Mr. Christine, in fact, these are not what I saw from books, I was taught by a doctor who traveled to the mainland, but he told me not to say it casually, since Mr. Christine asked, it is nothing ...... to tell you."

"Doctor?"

"Yes. Chen Luo nodded and said, "It all started with a winter three years ago, when the snow fell heavily in Yabo City, and an old man with gray hair fell at my doorstep......
