Qinghao is used to treat malaria.

This is beyond doubt.

A modern female scientist from Hua Country extracted artemisinin from qinghao to treat malaria, which also won her the Nobel Prize in Medicine.

Yun Jiao once watched an interview with this scientist. At the beginning of the team’s research, they were always unable to extract artemisinin from qinghao or failed to meet the standards.

One day, the female scientist flipped through Ge Hong’s "Emergency Treatment Manual" from the Eastern Jin dynasty, which contained a treatment for chills and fevers: "One handful of qinghao, soak it in two liters of water, extract the juice, and consume it completely."

After seeing this, the female scientist had an epiphany and tried the cold extraction method, ultimately succeeding in extracting artemisinin.

How much of the interview is exaggerated, Yun Jiao doesn’t know. However, it’s absolutely true that artemisinin can treat malaria and is superior to other herbs.

There was a time when people used quinine to treat malaria, but quinine had certain toxicity and caused significant harm to the human body, so it fell out of use.

Apart from qinghao, Yun Jiao also wrote down some other herbs that she plans to use to create herbal sachets for mosquito eradication.

After mosquitoes suck the blood of people infected with malaria parasite, they carry the parasite, and when they suck the blood of healthy individuals, they transmit the parasite to them.

Mosquitoes play the role of transmitters and intermediate hosts in the spread of malaria. Without mosquitoes, malaria actually lacks transmissibility.

Therefore, mosquitoes must be eradicated; otherwise, it’s difficult to eliminate this infectious disease.

Yun Jiao handed over the written materials to Prefect Wu.

Prefect Wu hurriedly wrote a memorial.

After finishing the memorial, Prefect Wu called his trusted aide, "Deliver this memorial to the Capital City as quickly as possible, day and night, with an eight-hundred-mile express."

The trusted aide solemnly stored the memorial and immediately set off.

Yun Jiao also spoke to Prefect Wu, "The Magistrate must organize a mosquito eradication campaign among households, and the city must also start mosquito eradication quickly. I suspect someone in the city has already been infected but hasn’t reported it yet."

Compared to outside the city, there are fewer trees, weeds, and ponds in the city, so there are also fewer mosquitoes, which might be the reason why the outbreak hasn’t occurred yet.

Prefect Wu nodded and instructed his subordinates to quickly notify the various government offices.

Yun Jiao didn’t wait long at the government office before a pharmacy delivered qinghao.

The qinghao from the pharmacy was sun-dried and cut into small pieces, making it difficult to extract juice.

Yun Jiao didn’t mind, taking several large pieces of gauze and soaking the qinghao in boiled cool water.

After soaking for half an hour, she had the soldiers wash their hands, wrap qinghao in gauze, and squeeze the juice.

Yun Jiao discussed with Prefect Wu, "Those with malaria outside the city should ideally be gathered inside the city, and a place should be reserved for them to live." 𝒇𝒓𝙚𝒆𝔀𝓮𝓫𝒏𝓸𝙫𝓮𝓵.𝓬𝙤𝙢

"Only by managing them well and preventing further mosquito bites can the transmission chain be slowly broken."

Prefect Wu repeatedly shook his head, "That won’t work; no matter what, they can’t be allowed into the city."

He couldn’t completely believe Yun Jiao’s claim that this disease doesn’t transmit from person to person.

As the Magistrate of Yangzhou, he had to be responsible for the people of Yangzhou.

If this Doctor Gu is unreliable, allowing those people into the city would lead to a large-scale infection, what then?

Yun Jiao frowned.

Conditions outside the city were inadequate for isolation.

It’s all shacks which can’t keep out mosquitoes.

Prefect Wu’s distrust also made her somewhat angry.

Suppressing her anger, she thought for a moment, "Then how about this? The Magistrate can organize to recruit large houses or estates in the western and northern parts of the city, gather carpenters to work day and night, and quickly produce screens for windows and doors. Once the screens are installed, transfer the patients to these places for centralized management."

In this weather, it’s impossible to keep all doors and windows closed; people would overheat.
