In the morning, Yuwen Wen, who had nothing to do when he was free, looked through his notepad, looked back at his "mind journey" and saw what else could be realized.

As I watched, I saw a piece of content and then felt sad.

"Emergency Preparation for Elbows": Prescription for treating malaria: Hold Artemisia annua, use two liters of water to soak it, twist it and take it all.

In the "Emergency Prescriptions for Elbows" written by Ge Hong of the Eastern Jin Dynasty, the "Artemisia annua prescription" in the "Prescription for Treating Cold and Heat" has clearly stated that Artemisia annua can cure malaria, and Artemisia annua is not a rare species in the Central Plains, so...

As long as a method to effectively extract artemisinin can be studied, the beast "malaria" can be subdued. Then large-scale development of Lingnan, Jiaozhou and even Nanyang is not a problem. Therefore, Yuwen Wen devoted his manpower, material resources and financial resources with hope to study how to effectively extract artemisinin.

It took more than twenty years, but there was still no progress.

For more than 20 years, all propeller-propelled steamships have been developed, but artemisinin cannot be extracted.

Obviously, if you don’t have the skills, it’s not possible, so it’s better to go to America to find the cinchona tree.

Thinking of this, Yuwen Wen sighed: Even if he successfully "discovered" America, can the cinchona tree be found?

America is so big, but I know where the cinchona tree grows. If the expedition team only searches for it, it may not be found for decades. So the relatively reliable way is to inquire with the indigenous people.

However, even if you can find the natives and still have friendly contacts with the other party, it is unknown whether the other party knows this kind of tree. Perhaps the expedition team is asking about a strange tree that can cure malaria, and people think you are looking for a sacred tree that treats infertility.

Yuwen Wen only knew the four words "Jinjina Tree". As for the appearance of Jinjina Tree (leaf, bark, flowers, and fruits), he didn't understand at all. The expedition team relied on this term to inquire with the natives, which was probably similar to finding a needle in a haystack.

Or, the natives understand what tree are outsiders looking for, but they regard this tree as treasure and refuse to say it easily. Then the expedition team can find this thing in the year of the monkey and horse month?

Yuwen Wen felt pessimistic, probably in his lifetime, he would not be able to wait for the cinchona tree.

There are many specialty plants in the Americas, but what Yuwen Wen wants to find the most is the cinchona tree, which is more important than tobacco, corn, potatoes, and cocoa. After all, the only medicinal plants that can treat malaria in the world are Artemisia annua and cinchona.

If it can effectively treat malaria, it can effectively develop the South China Sea and greatly increase the survival rate of Central Plains immigrants in the South China Sea. This is an effect that American crops such as tobacco, corn, and potatoes cannot achieve.

Yuwen Wendong thought about it, and his thoughts returned to Artemisia annua: The cinchona tree may not be found in the lifetime. Could it be that how to continue to work hard to squeeze juice for Artemisia annua?

He was stunned when he looked at the notepad, as if he had entered a meditation. After a long time, he heard a voice in his ear: "Erlang?"

"Um?"

Yuwen Wenxun looked at him, but it was Yuchi Chifan who came and sat beside him.

Seeing the other party wearing gorgeous clothes and light makeup, Yuwen Wen blurted out, "You... are you going to have an interview?"

When Yuchi Chifan heard this, he felt inexplicable: "Interview? Why do you start with this?"

"Ah...then..." Yuwen Wen's mind was a little confused and suddenly couldn't come back to his senses. Seeing him like this, Yuchi Chifan smiled and said, "I'm just chatting with the foreigners in the life-saving house."

"Oh...so that's it..."

Yuwen Wen nodded. For the queen, an important place of social interaction is the Virtue House (or similar institution). Women who are out of the palace will regularly visit the palace to meet the queen. A group of women will "gossip" at the Virtue House, and talk about some family matters.

But that was the past, and now the queen has no time to "gossip". Basically, every time she meets a foreign woman, she is talking about the industry. After all, many foreign women are in charge of their own industries and have many related topics to communicate with the queen.

Since Xia Chuyu and Yuwen Wen returned to Chang'an, Yuchi Chifan has been busy. He has to hold a symposium with foreigners at the Fate Maid's House every now and then, talking about many industrial matters, and today is no exception.

So what do I do?

Yuwen Wen thought so, and his attention quickly turned back to the notebook. When Yuchi Chifan saw that this person started to get distracted again, he quickly said, "Erlang, I want to say something."

"Ah? What's the matter..."

"That's right, the alfalfa grown in the pastoral prison is one of the good pastures. It is also planted everywhere now. It's just that there is a distinction between real and fake alfalfa. If a horse eats fake alfalfa, it will be poisoned, so..."

Yuchi Chifan was asked by several foreign women. He wanted to ask Yuwen Wen to add some real alfalfa seeds to his favor. This was no big deal, and Yuwen Wen had no objection.

What Yuchi Chifan said about real and fake alfalfa refers to alfalfa (real alfalfa) and alfalfa (fake alfalfa). These two plants look very similar at first glance, and it is easy for laymen to get confused.

Speaking of alfalfa and Zi Yunying, Yu Wen Wen suddenly remembered the past and the funny scene when he treated Zi Yunying as alfalfa outside Yecheng.

I remembered the Wrangler and Ma Wu who pointed out the mistake in person, and Yuchi Mingyue who covered her mouth and laughed.

My brother-in-law and sister-in-law have already achieved success. Thinking of the bright and charming Yuchi Mingyue, Yuwen Wen was a little excited: Yuchi Mingyue is pregnant and can no longer serve in bed.

During his days in Luoyang, Yuwen Wen and the beauties were extremely happy, and they had a lot of results: Chen Wu, Chen Wu, and Yuchi Mingyue were pregnant one after another, so his "combat power" in the harem instantly lost 40%.

After putting away his thoughts, Yuwen Wen and Yuchi Chifan talked about alfalfa and gave the other party a few words about how to distinguish between real and fake alfalfa. As he spoke, he also picked up the strokes to let Yuchi Chifan know what the difference between real and fake alfalfa leaves and flowers.

Yuwen Wen was concerned about Ma Zheng, so he was very familiar with alfalfa. Yuchi Chifan looked at the sketch and quickly figured out how to distinguish the authenticity. He smiled and said, "It turns out that alfalfa is like Artemisia annua, and there are such similar fakes."

"Not that, this.....Hmm? What did you say?"

"Ah? What I'm talking about..." Yuchi Chifan was stunned by Yuwen Wen's abrupt question, "I said... It turns out that alfalfa is like Artemisia annua, and there are such similar fakes..."

Yuwen held Yuchi Chifan's hand, his eyes were dull, and he asked: "You... talk about the fake Artemisia annua?"

"It seems to be... I chatted with a foreign wife a few days ago. I heard them say that there are several types of artemisia. If you follow the doctor's prescription, you must not be confused when taking medicine. Once it is confused, the decocted medicine will be ineffective..."

Yuchi Chifan continued, but Yuwen Wen couldn't hear it, his head buzzed, and his eyes were unconscious.

He had known how many types of artemisia before, but now he thought of a thrilling possibility: Maybe it is not necessarily extracted from artemisia that can cure malaria?

For example, although drug cannabis is extracted from the "heat" plant, the textile crop "heat" native to Central China has extremely low marijuana composition. It is said that the "heat" plant native to India, "Indian cannabis", is the refining plant of cannabis.

Therefore, if any criminal wants to get rich, using textile hemp from Zhongyuan to refine cannabis will only go bankrupt.

So, did I make a mistake in the target plant for artemisinin extraction?

Is the "Artemisia annua" in "Emergency Prescriptions for Elbows" different from the Artemisia annua I understand?
