Daming: The county magistrate cried poorly and Zhu Yuanzhang exploded in anger

Zhao Yuhe shook his head and said, "This time it's not a letter from Ying Tianfu."

"That is……"

"It's Mr. Zhu's letter." Zhao Yuhe said, "You haven't eaten lunch, it's been every day!"

"Let's eat together at noon and evening, and give me the letter. I'll see what Mr. Zhu told me." After Zhang Song finished speaking, he stretched out his hand to Zhao Yuhe.

Zhao Yuhe pouted and said, "Let's eat first."

Zhang Song had no choice but to eat first.

After eating, he stretched out his hand to Zhao Yuhe.

Only then did Zhao Yuhe hand the letter to him.

Hastily opened the letter, opened the letter and read it by candlelight.

Looking at Mr. Zhu's letter, Zhang Song's heart sank immediately.

It turned out that Mr. Zhu's letter said that the epidemic that broke out in Liuhe County had already broken out in the entire Jiangnan area.

It is a hidden danger left by the last flood.

He said that since cholera could be eradicated within a few days, he hoped that he could take action to suppress the epidemic.

Zhang Song diagnosed the symptoms of this epidemic based on Western medical diagnostics, and initially determined that it was undoubtedly typhoid fever.

Typhoid fever was a very terrible epidemic in ancient times.

Although Zhang Zhongjing, a medical sage 1000 years ago, left a Treatise on Febrile Diseases, treating people according to this book can save many lives.

But traditional Chinese medicine is very friendly to mild patients, but for severe patients, it is almost resigned to fate.

Those who are superstitious about Chinese medicine think that Chinese medicine is omnipotent.

That would be dead wrong.

After all, what Chinese medicine is good at is to prevent illnesses through work.

To put it simply, it is to treat the symptoms of the disease as soon as it is discovered.

In this way, mild patients have almost a very low mortality rate.

This is why in later generations, when treating infectious diseases, the death rate of western medicine is higher than that of traditional Chinese medicine.

Western medicine almost treats patients who need to wear ventilators and oxygen masks.

There is not much time left for Zhang Song now.

More because, his current level is limited.

It is impossible to produce a complete set of equipment for Western medicine.

To put it bluntly, his current level is no different from that of the barefoot doctors of later generations.

It can only be treated with simple drugs.

It is impossible to carry out auxiliary treatment with Western medicine equipment.

Even infusions and complete antibiotics are not available.

He is now grinding his guns in front of the battle and producing drugs to fight diseases according to his condition.

Zhang Song had countless thoughts in his mind at this moment, and after considering each thought, he chose a suitable method for the moment.

According to the medical conditions brought back by the county clerk, he judged that the epidemic this time might be malaria.

Malaria was also a very terrible epidemic in ancient times.

But as a time traveler, I have a lot of confidence in my heart.

The most effective of this kind of thing belongs to Ning Kui.

But after all, the synthesis of Ningkui is more troublesome. The first choice is to mention artemisinin in Chinese herbal medicine.

Artemisia annua is the main drug in the treatment of malaria.

Moreover, Artemisia annua is also a mosquito-repellent incense among the people.

People in ancient rural areas collected Artemisia annua in summer and bundled it into grass handles.After drying in the shade, light it at night to repel mosquitoes.

This primitive method works very well.

Inspired by this point, ancient doctors used Artemisia annua to treat malaria, and the effect was quite remarkable.

But artemisinin is mainly distributed in the leaves of Artemisia annua.

Ancient doctors had only two methods. One method was to boil it, and the other method was to make it into pills and powders.

Neither of these two methods can isolate the active ingredient artemisinin in Artemisia annua.

Therefore, only with the help of future technology.

But Zhang Song was in trouble again.

There is no way to extract artemisinin in his knowledge.

You can only check in the system store to see if there is information about artemisinin extraction.

If there is, it is dead expensive.

A stack of artemisinin information requires [-] system points!
His current remaining system value is only a few dozen points.

"Hey, the system has been with me for almost two years, and I'm still so poor!"

Station Construction looked at the poor system and was speechless for a while.

I thought it would be great if the system released tasks again, I really want to earn some system value...

However, the system releases tasks very freely, and sometimes it seems that it is deliberately embarrassing Zhang Song.

Zhang Song complained: "System, why can't my system value be rich?"

"That's because the host is still in the development stage! When the version of this system is upgraded to 8.0, the tasks issued by the system can be easily obtained by the host."

Zhang Song was also drunk when he heard what the system said. How did this guy come up with such a trick?

Make yourself feel an explosion.

Then he asked the system: "So when will I upgrade to 8.0?"

"Look at the chance. Measured by your contribution to Daming! If you can help Daming survive three crises, I think it's almost the same. But for now, you can only work hard to build Liuhe County and make some achievements. Show Lao Zhu."

Hearing what the system said, Zhang Song finally felt at ease.

It seems that a five-year plan must be drawn up.

It is an excellent tradition of our Great China people to act after making a decision.

Excellent traditions will naturally not be lost.

So Zhang Song started to make a draft in the bottom of his heart.

First determine a mainstream development direction, and then slowly enrich the content program.

Of course, the most important thing at present is how to survive this wave of malaria.

After buying the information on artemisinin, he began to study the information on artemisinin.

How to extract artemisinin.

Time passed by minute by minute, and after an hour, he finally finished reading the artemisinin extraction materials.

After reading it, he first prepared some utensils and equipment.

In the age of civilization in which his predecessor lived, many countries in the world were still plagued by malaria.

Although malaria is almost eradicated in the country he lives in.

It can be seen that even after the disappearance of smallpox, typhoid and other infectious diseases, malaria can still exist. This is mostly due to the existence of mosquitoes...

It is almost impossible to completely eradicate malaria.

He can only go down the control box.

To control malaria, one is to kill mosquitoes, and the other is to use specific drugs.

Quinine is extracted from the cinchona tree, and quinine has a lot of side effects.It has more side effects than the extract of Changshan, a traditional Chinese medicine that can intercept malaria.The extraction of artemisinin is not a simple matter.

For the era in which his predecessor lived, it took an expert more than ten years to successfully extract artemisinin.

Although he is eating ready-made food now, it still takes time to explore and master it.

After all, what you read in books and what you see in reality are completely different things...

He spent several hours studying this information, and based on this information to explore and experiment.

After watching for a long time, exploring for a long time, the last step is to experiment.

Before the experiment, Artemisia annua was obtained.

He found that it was Zi Shi now.In the middle of the night, which pharmacy will open the door?

Therefore, it is still unknown whether the Artemisia annua herb can be found.
