I practiced medicine in ancient times

Chapter 167 Artemisia annua

Xu Qingyi knew that in order to treat malaria, he must find a drug that can kill the malarial parasite.

However, this is not easy. In ancient times, people's knowledge of diseases was very limited, let alone such an elusive disease as malaria.

"Qingyi, do you have a cure for malaria?" Bai Yan asked.

"Of course there is. Don't forget that artemisinin is specifically used to treat malaria."

"Oh! That's right! How could I forget about artemisinin? Qingyi, can you make artemisinin?" Bai Yan just remembered it then, and she slapped her head and said embarrassedly.

“Without the solvent to extract artemisinin, I have no way to produce artemisinin.

However, oral Artemisia annua can also treat malaria. When combined with other medicinal herbs, the effect is not as good as artemisinin, but it is not much weaker.

It's just a matter of extending the time it takes to take the medicine." Xu Qingyi explained.

“Qingyi, you are good at this, so I will leave it to you. Go and prepare the herbs quickly so that you can cure these people’s malaria as soon as possible, so that they will suffer less.

Also, I believe that there are many people in Youzhou City who are waiting for your prescription to treat malaria.

If we can solve the problem of malaria in Youzhou City, there will be no more deaths from malaria in Youzhou City in the future, which can save a lot of people, and it will be a great merit." Bai Yan urged.

Xu Qingyi quickly wrote out three prescriptions and drew two pictures.

Among these three prescriptions, one is for treating malaria, with Artemisia annua as the main medicine, and other insecticidal and anthelmintic herbs such as Dichroa febrifuga, Amomum villosum, and Honeysuckle. Drinking this prescription can cure malaria in as short as seven to ten days, or as long as half a month.

The other prescription was for those patients who had malaria and were too weak to bear the consequences. Xu Qingyi added a few more nourishing herbs to the original prescription to help the patients recover and prevent them from being too weak to bear the consequences during the treatment of malaria.

The third prescription was one that Xu Qingyi prepared for fumigating mosquitoes.

There are two drawings, one is a drawing of making mosquito coils, and the other is a drawing of making a mosquito coil box.

This mosquito coil box can be used to light mosquito coils, put them inside, and then hang them around the waist. It can be carried by herders to repel mosquitoes and protect them from mosquito bites. This design is both practical and convenient, allowing herders to enjoy peace and comfort while working in the wild.

It can also reduce the chance of being bitten by mosquitoes and subsequently contracting malaria.

Not long after Xu Qingyi wrote the prescription, Lai Fu walked towards Xu Qingyi and the others with a booklet.

"Doctor Xu, this booklet contains records of people in Youzhou who have been infected with this disease. I sorted it out and arranged the patterns you mentioned. Due to the short time, I only had time to sort out a part of it, probably only about a hundred people. I hope it will be useful to you." Lai Fu handed the letter in his hand to Xu Qingyi.

"Let me take a look." Xu Qingyi took the letter, read ten lines at a glance, and finished reading it quickly.

Most of the people found to be sick were herders, and they also had a lot of red spots on their bodies from mosquito bites.

The most important thing is that the fixed time, pulse and other conditions are consistent with my own judgment, which further confirms that I am infected with malaria.

"That's right, malaria.

These three prescriptions... Prepare them as soon as possible, boil them and send them to them for consumption. Prepare the mosquito coil boxes and mosquito coils as soon as possible. "Xu Qingyi handed the prescriptions to Lai Fu and explained them to him.

"Okay, I'll go right away." Lai Fu's face showed great joy when he saw that Xu Qingyi and Bai Yan had found the cause and treatment of the strange disease with a very high mortality rate in Youzhou City in such a short time.

In this corner of Youzhou City, there are still many people suffering from this strange disease. Not only are they in great pain, but they are also in panic.

However, if Xu Qingyi and Bai Yan could find the cause and treatment of this strange disease, it would be like a ray of light, illuminating their hope.

It is a great deed that will bring immeasurable merit and benefit to the people of Youzhou City.

But not long after Lai Fu left, he hurried back and said to Xu Qingyi anxiously, "Doctor Xu, I just took your prescription to the palace doctor and found that the herb Artemisia annua in the prescription is not available in the palace.

Can this herb be replaced by other medicines?"

"No, Artemisia annua is the most important herb for treating this disease.

If this herb is missing, the efficacy of this prescription will be greatly reduced." Xu Qingyi frowned slightly. She naturally knew the importance of Artemisia annua. This herb can clear away heat and detoxify, and is the key to treating malaria.

"But, there is indeed no such herb in the mansion's medicine storehouse." Lai Fu looked embarrassed. He knew that although the mansion had abundant reserves of medicinal herbs, the only herb missing was Artemisia annua.

Artemisia annua contains artemisinin, but in fact, this Artemisia annua is not Artemisia annua.

Although the two have certain similarities, they are different species. The reason for such confusion is that the two are not only similar in appearance, but also in function, which leads to the confusion as above.

Artemisinin can only be extracted from Artemisia annua, but not from Artemisia annua. In the treatment of malaria, if Artemisia annua is lacking, it is like cooking without salt, and the food will not taste good.

“There’s none in the palace, but there should be some outside.

I mean there is fresh Artemisia annua growing on the prairie.

I will draw a picture of Artemisia annua for you. You can take it to the local elders in Youzhou City and ask them, especially those who often go out to graze. They should have seen Artemisia annua. "Xu Qingyi said, and then he picked up a pen and paper and began to draw the appearance of Artemisia annua.

After a while, the painting was finally completed and handed to Lai Fu.

After Lai Fu got the blueprint, he hurriedly found the shepherd and asked where he had seen the plants on Xu Qingyi's blueprint.

"Just these two strange diseases? I thought it was some other strange disease, but it took less than one morning and you, Qingyi, easily solved it. I didn't even have to do anything." Seeing this, Bai Yan said happily and relaxedly.

“Let’s first see the effect of the prescription and see if it can cure the two diseases.

If I want to go back, I’m afraid it won’t be so quick. It will take at least a month.

Also, it won’t be possible to cure the prince’s mania in a short period of time. ” Seeing Bai Yan like this, Xu Qingyi smiled and shook her head.

Before coming to Youzhou City, Xu Qingyi was worried that this strange disease would be very difficult to treat. Unexpectedly, after arriving in Youzhou City, she found that this strange disease was not difficult to treat, at least it was much better than expected.

It's tricky, and it depends on the person.
