Artemisia annua is used to treat malaria.

There is no doubt about it.

A female scientist in the modern flower country extracted artemisinin from Artemisia annua to treat malaria, and won the Nobel Prize in Medicine.

Gu Yunjiao once watched an interview with this scientist, and at the beginning of the team's research, it was always impossible to extract artemisinin from Artemisia annua, or it did not meet the standard.

A female scientist once turned to Ge Hong's "Elbow Reserve Emergency Prescription" in the Eastern Jin Dynasty, which wrote the prescription for treating cold and heat: a grip of Artemisia annua, two liters of water, wringing the juice, and taking it.

When the female scientist saw it, she suddenly realized that she tried to use the cold brew method, and then she successfully extracted artemisinin.

How much water there is in this interview, Gu Yunjiao doesn't know, but it is true that artemisinin can treat malaria, and it is better than other medicinal materials.

For a while, people used to use cinchona cream to treat malaria, but cinchona cream had a certain toxicity and caused great harm to the human body, and then no one used it.

In addition to Artemisia annua, Gu Yunjiao also wrote some other medicinal materials, which she planned to use to make some herbal packets to kill mosquitoes.

When mosquitoes suck the blood of infected people, they carry the parasites, which they pass on to healthy people.

Mosquitoes play the role of transmitter and intermediate host in the transmission of malaria, without which malaria is not actually contagious.

Therefore, it is necessary to eradicate mosquitoes, otherwise it will be difficult to eradicate this infectious disease.

Gu Yunjiao handed over the written things to Governor Wu.

Governor Wu hurriedly wrote an excerpt.

After writing the excerpt, Wu Zhifu called the guard, "This letter is a tribute, day and night, and it will be sent to the capital in an expedited manner of 800 miles." ”

The guards solemnly put away the folds and set off immediately.

Gu Yunjiao said to the prefect of Wu again: "The prefect will also organize every household to launch a campaign to exterminate mosquitoes, and the city must also start to exterminate mosquitoes as soon as possible, I suspect that there must have been people infected in the city, but it has not been reported yet." ”

Compared with the outside of the city, there are fewer trees, weeds, ponds, and mosquitoes, which may be the reason why there has not been an outbreak in the city.

Governor Wu nodded, and instructed his subordinates to hurry up and report to the yamen everywhere.

Gu Yunjiao waited for a long time in the prefect's yamen, and a pharmacy sent Artemisia annua over.

Artemisia annua in pharmacies is dried and cut into small pieces, which is not easy to juice.

Gu Yunjiao didn't care, got a few pieces of large gauze, and soaked the Artemisia annua in boiling cold water.

After soaking for two quarters of an hour, the soldiers were asked to wash their hands and wrap the juice in gauze.

Gu Yunjiao discussed with Governor Wu again, "If you have malaria outside the city, it is best to gather all of them in the city and make room for them to live." ”

"Only by keeping them under good care and not allowing mosquitoes to bite them again can the chain of transmission be slowly broken."

Governor Wu shook his head again and again, "That's not good, you can't let them enter the city if you say anything." ”

He never fully believed what Gu Yunjiao said, this disease will not be transmitted from person to person.

As the prefect of Yangzhou, he is also responsible for the people of Yangzhou.

What if this Dr. Gu is unreliable and lets those people into the city and causes a large-scale infection?

Gu Yunjiao frowned.

There is really no segregation outside the city.

They are all shacks, and they can't keep mosquitoes out.

Governor Wu's distrust of her made her a little annoyed.

She suppressed her anger and thought for a moment, "Then let's do it, the prefect will come forward to collect a few big mansions or large manors in the west and north cities, gather carpenters, work day and night, and make screen windows and doors as soon as possible. ”

In this kind of weather, it is impossible to completely close the door, it will be hot to death.
