"Your Highness, are you sure you want to use Artemisia annua instead of Artemisia annua?" Cui Wei was still a little uncertain and asked again. Just now, Li Su said that he should prepare a medicinal herb, but what he didn't expect was that what Li Su was looking for turned out to be stinky artemisia.

The so-called stinky artemisia is actually a kind of artemisia grass, which belongs to a different species from the kind of mugwort that ignites the smoked mosquito for a hundred days. In fact, there are many artemisia herbs that can be used in medicine, such as mugwort, Artemisia annua, etc., which are commonly used for medicinal purposes, but Artemisia stinkensis is different, because it has a strong odor, so few people use it for medicine.

"Yes, to be exact, a yellow-green stinky artemisia with small yellow huā" and preferably fresh, the stronger the taste, the better! Li Su reminded again. In fact, Artemisia stinkensis is also divided into several types, among which only Artemisia huanghuā has the effect of treating malaria.

Speaking of malaria, Li Su mainly heard from a friend in his previous life, this friend went to Africa for work, talked about his malaria and almost died, and also popularized the relevant knowledge of malaria to Li Su, so Li Su was very impressed, knowing that the artemisinin in Huanghuā Artemisia is the nemesis of malaria, so he is so sure.

"This ......" Cui Wei looked at Li Su's confident look, obviously very sure, and it was not easy to say anything for a while, he carefully recalled the stinky artemisia described by Li Su in his mind, and immediately thought of a plant, nodded and said: "Okay, since His Royal Highness insists, then Xia Guan will do it, according to the form of stinky artemisia that His Highness said, it should be called wine cake grass by the southerners, and there are many places where it grows in Liuqiu, so Xia Guan will send someone to collect it!" ”

Li Su was also overjoyed when he heard that Cui Wei already knew what kind of artemisia grass it was, and immediately asked Cui Wei to hurry up, after all, saving people is like fighting fires, if he hadn't been for Liwei before, he wouldn't have delayed until now to remember.

Cui Wei is worthy of being a person who can do the history of assassination, and his efficiency is really not comparable to ordinary people, and before he left, he had already sent someone to send the first batch of Huanghuā Artemisia, and all of them were freshly cut. In fact, this kind of yellow huā artemisia because of its own peculiar smell, plus a little poison, so no one eats it at all, but some ethnic minorities in the south will use it to make wine, and this is also the origin of the name of the wine cake grass.

Artemisia huanghuā has tenacious vitality, so it is almost everywhere in the mountains and roadsides, and most people just regard it as a weed, and no one has thought that this thing is actually a fairy grass that can treat malaria.

"Your Highness, you don't want to use the stinky artemisia to boil the medicine for those people on the ship, do you?" Looking at the stinky artemisia that had been piled up like a hill in front of her, Cui Mengxue asked speechlessly. After resting for a while, she immediately ran to urge Li Su to save people, but she didn't expect to see such a bunch of stinky artemisia.

Cui Mengxue has studied medicine for so many years, so she naturally knows that some predecessors have proposed to use Artemisia annua to treat malaria, but it is Artemisia annua and not Artemisia stinky. And she also consulted Sun Simiao, but the other party told her that the use of Artemisia annua as a medicine has no effect on malaria at all. As for using stinkwood into medicine, Cui Mengxue felt even more nonsense, because she had never heard that stinkwood could also be used in medicine?

"Of course this thing can't be used to boil medicine!" Li Su smiled mysteriously. And when Cui Mengxue heard it, she immediately put her mind at ease, thinking that her memory was really right, and stinky artemisia really couldn't be used in medicine!

Fa didn't wait for Cui Mengxue to be happy for too long, but he heard Li Su continue very confidently: "But this stinky artemisia is used to squeeze juice for patients to drink, as long as you drink this, you will definitely be able to cure malaria!" ”

"Juicing?" Cui Mengxue was even more surprised when she heard this, she didn't expect that some herbs really can't be boiled with fierce fire, otherwise they will lose their medicinal effect, is this the same for this stinky artemisia? In fact, Cui Mengxue guessed that the artemisinin in stinkwood is the main ingredient in the treatment of malaria, but if it is heated, the artemisinin will be destroyed, and naturally it will not have any effect.

Li Su looked at Cui Mengxue's surprised appearance, and was even more proud in his heart, and commanded people to squeeze all the stinky artemisia sent by Cui Wei into juice, and then use several large barrels to send them to the fleet outside the port in small boats, so that the sick people can drink as much as they can, after all, the effective ingredient in this is only artemisinin, and Li Su doesn't know what the artemisinin content in Stink Artemisia is high, so let them drink more insurance.

However, in Li Su's opinion, it is not enough to let the people on the ship drink the stinky artemisia juice, after all, the weather in Keelung Port is hot, and there are many mosquitoes, and two days is enough time for them to spread the malaria parasite. Therefore, Li Su did not let Cui Wei stop collecting Artemisia annua, but sent more people to assist him and speed up the collection of Artemisia annua.

Early the next morning, Li Su asked Lu Qing to post a post in the whole city, warning the people of the city, asking them to go to the city gates to collect herbs as soon as possible, and even set up a special medicine collection office in the port. Anyway, artemisinin can not only kill the malaria parasite, but also other parasitic diseases, in addition to the cooling and antipyretic effect, so it is not bad to drink as an herbal tea, of course, provided that you get used to the strange taste.

Artemisinin is indeed the nemesis of malaria, and the people on the waiting fleet drank the stinky artemisia juice, and the next day they really felt that their condition was better, and this not only made Li Su and their confidence greatly increased, but also let those patients see a glimmer of hope for survival in despair, so they immediately became active, and every time the vat containing the stinky artemisia juice was sent to the ship, it would cause a scramble, and everyone wanted to drink a little more in order to make themselves better faster.

After three days, the condition of the malaria patients on the ship really improved greatly, and even a few of them recovered faster, almost like ordinary people, but they still had to stay on the ship for safety. Of course, not everyone can be cured, for example, there are several terminally ill crew members on the ship, even if they drink stinky artemisia juice, but their condition does not improve in the slightest, and finally they die in pain.

After all, relying only on the primitive practice of squeezing the juice of artemisia annua, the content of artemisinin is extremely low, and at most it can only have an effect on patients in the early and middle stages, and as for the late stage of malaria, it is estimated that it will not have much effect.

In addition, it is worth mentioning that Li Su did not deliberately keep it a secret that stinky artemisia can treat malaria, after all, it is difficult to escape the eyes of people who care about such a big move as the acquisition of stinky artemisia. In addition, Li Su did not make money with this thing, and it was also related to the lives of countless people, so Li Su simply announced the function of stinky artemisia, and sent people to notify several major ports close to Liuqiu, and asked local officials to report to the imperial court, after all, malaria is a common plague, and if you can prepare earlier, you may be able to save many people's lives.

Of course, Li Su is not such a pedantic person, the weather in the south is hot, and malaria must not be eradicated, so after the efficacy of stinky artemisia is announced, it will definitely double its value, and the wild one alone will definitely not be able to meet the requirements, so he has been discussing artificial planting with Yanbei, Cui Yu, Wang Kuang and others, but this matter is not so easy, at least the habits of stinky artemisia must be understood in advance, so after they discussed it, each of them contributed a part of the funds, and then organized people to conduct trial planting, The resulting technology is shared by everyone.

After solving the malaria matter, Li Su finally had to deal with the mysterious force in Tainan. Of course, with his identity, he naturally wouldn't go to the other party to take risks, Lu Qing had already sent someone to inform the other party, so that they could come to Keelung to meet, and if the days were counted, there would be news in the next two days. However, Li Su did not wait for the other party all the time, he still had one more thing to do before meeting the leader of that mysterious force.

Li Su was accompanied by more than a dozen guards such as Xi Junmai, led by a henchman of Lu Qing's faction, and after passing through several heavily guarded checkpoints, he entered a tall cement building, and from time to time there were teams of patrolling soldiers walking by, and when they saw Li Su and them, they immediately saluted.

The place where Li Sulai is located is the Niu Chou Port when he landed, and it has been explained before, the Niu Chou Port is moored with warships, and the land around the port is also a military stronghold, and the defense is very tight, but it is also the use of this, there is also a building in Niu Chou Port, that is, the prison of Keelung City, and this is the reason why Li Su came to Niu Chou Port today.

The prison keeper's surname is Huang, a middle-aged man in his forties, he has already received the news that Li Su is coming, so he has been waiting in front of the gate, and when he saw Li Su and his party, he immediately greeted him, bowed down and said: "Keelung Prison Cheng Huang You, see the prince!" ”

"Huang Prison doesn't need to be polite, take me to meet those three people!" Li Su raised his hand and said. What he wants to see today is the three assassins who assassinated Lu Qing at the beginning, when the three were captured, Lu Qing admired the strength and character of these people, so not only did he not kill them, but also sent doctors to treat their injuries, but these three people were not ordinary people, Lu Qing was afraid that they would escape, so he sent them to prison for care.

"Please come with Your Highness!" Huang Prison Cheng heard Li Su's order, he didn't dare to slack off at all, immediately opened the gate of the prison, and then led the way in front, Li Su also followed into the gloomy prison, but because this prison is newly built, there are not many prisoners inside, so there is no peculiar smell.

Under the leadership of Huang Jiancheng, Li Su soon came to the deepest part of the prison, where the felons were kept, the iron bars on the cells were obviously thicker than the outside, and there were special guards, which could be described as heavily guarded.

When he arrived at the felony cell, he didn't need to be introduced by Huang Jiancheng, Li Yu couldn't find the three killers he was looking for at a glance, because only the three of them were held here, and each of them had a separate small room, which was very clean, and it seemed that they were treated well here.
