Changshan is a Chinese herbal medicine and poisonous.

Changshan is very toxic and can irritate the mucous membrane of the gastrointestinal tract, causing violent vomiting.

It can also damage the walls of intestinal capillaries, causing congestion or bleeding in the gastrointestinal tract, dilating blood vessels, inhibiting the heart, and lowering blood pressure.

After poisoning, there will be nausea and vomiting, abdominal pain, diarrhea, blood in the stool, bradycardia, arrhythmia, conduction block, blood pressure drop, etc.

In severe cases, the lips turned purple, and finally the circulation paralyzed and died.

Changshan contains Changshan minus, in which Changshan alkali propylene is 150 times more effective in treating malaria than quinine.

When Tu Youyou's research group researched a special drug for the treatment of malaria, Changshan was the first to try, because Changshan is the most common malaria treatment in medical books.

Tu Youyou's team also successfully extracted Changshanine with antimalarial activity, but they found that Changshan is not a good medicine, because although Changshan can treat malaria, patients are more likely to be poisoned by this thing before malaria cures malaria.

Tian Jiajia wanted to find something that could remove Changshan's toxicity, indicating that her experiment should need Changshan without toxicity.

For the method of neutralizing or removing the toxicity of Changshan, Yang Xin naturally does not know, Chinese medicine has discovered Changshan for thousands of years, and no one has found a way to remove the toxicity of Changshan.

However, although Yang Xin didn't know, he could ask the system.

"Xiaowei, does the system have any medicinal materials that can neutralize or remove Changshan's toxicity?" Yang Xin asked Xiaowei.

"Of course there is, but it's expensive, and it costs three hundred points. Xiao Wei said to Yang Xin.

"What?300 points?" Hearing that he wanted 300 points, Yang Xin was immediately not calm.

"Why is it so expensive, a few years ago, I only had a dozen points for a prescription for rheumatism. Yang Xin asked Xiaowei.

"Because you only had that few points at the beginning, the system took into account that you couldn't get more points, and you needed some money to develop yourself in the early stage, so they exchanged them for you at a super low price. ”

Xiao Wei said to Yang Xin: "If you exchange the rheumatism treatment method at the original price now, the price is four thousand points, so you have made a lot of money." ”

"Then if I want to redeem a drug that can completely cure AIDS now, how many points do I need?" Yang Xin asked Xiaowei.

"Five thousand points, you can redeem them. Xiaowei said.

"Well, I can see it, the system just can't see that I have points, I finally saved more than 300 points, and I want to spend them all when I open my mouth. Yang Xin said to Xiaowei.

Yang Xin pondered, do you spend 300 points to exchange for the method value of removing Changshan's toxicity? 300 points, it's too much, and the top ten students have completed a high school task.

"Jiajia, is it very important to remove Changshan's toxic things for your experiment?" Yang Xin sent a message to Tian Jiajia.

"It's very important, if we can find a way to remove the toxicity of Changshan, the biggest problem of the AIDS drug I am researching will be gone. Tian Jiajia replied.

"Then I'll help you find a way to find it, I can't guarantee that I will be able to find it. Yang Xin replied to Tian Jiajia.

"Whether or not I find a way, I have to thank the teacher. Tian Jiajia replied.

After finishing Hetian Jiajia's message, Yang Xin said to Xiaowei: "Xiaowei, help me exchange the method of removing Changshan's toxicity." ”

"Good host. Xiaowei responded.

Soon, Yang Xin's points were deducted by 300 points, leaving only 40 points.

After the points were deducted, in the next moment, two ways to remove and neutralize Changshan's toxicity appeared in Yang Xin's mind.

The method of removing and neutralizing Changshan requires several equally toxic plants, plus more than a dozen other non-toxic plants, which can be completely removed or neutralized by special processing and special steps.

Half of these plants are common Chinese herbal medicines, and several plants are not included in the Chinese medicine spectrum.

For example, it grows at the foot of a snow-capped mountain at an altitude of several thousand meters, a high-altitude poisonous herb, which is never seen by ordinary people, so no one uses it for medicine at all.

There is another plant that is not found in China, and only grows in abundance in Siberia, and perhaps a small amount can be found on the border of Heilongjiang.

Traditional Chinese medicine believes that all things are mutually reinforcing, and any disease has something to restrain him, if not, it means that he has not yet found a way to restrain him.

There are more than 30 million known plant species in the world, and the number is slowly increasing over time.

With so many plants, it is impossible for Chinese medicine to eat them all.

If you can't eat it thoroughly, you can't develop a drug for a certain disease.

And Yang Xin is different, he has a system, as long as he is willing to spend points, the treatment of any disease can be exchanged.

It's just that the points needed will make people's scalp tingle.

After exchanging the method of removing and neutralizing the poison of Changshan, Yang Xin did not send it to Tian Jiajia immediately, but asked someone to help find those medicinal materials.

In this world, as long as you are willing to spend money, there will be many people who are willing to do anything for you.

In less than a week, more than a dozen medicinal materials were sent to Yang Xin.

Yang Xin's teaching laboratory has a lot of test equipment, and Yang Xin doesn't need to go to other places, so soon, he started the experiment according to the method given by the system.

After many experiments, he finally removed some of Changshan's toxicity.

After removing the toxicity, Changshan doesn't have to worry about poisoning even if you eat it as a meal.

Subsequently, Yang Xin asked people to send these Chang Shan to Tian Jiajia to remove the toxicity.

"Teacher, no! Although these Changshan are no longer toxic, some medicinal properties have also been destroyed......

Half a month later, Tian Jiajia called Yang Xin and said.

"Don't worry, maybe my experiment is wrong, you are waiting for me for a while, I'll try it for you." Yang Xin Chaotian Jiajia said.

The first method is to remove the toxicity, but it will destroy the medicinal properties of Changshan.

So Yang Xin chose the second method of neutralizing Changshan's toxicity.

A few days later, Yang Xin once again asked people to send some Changshan to Jiajia in the field.

Just when Yang Xin sent the processed Chang Shan to Tian Jiajia again.

On June 7, the national unified college entrance examination also began.

More than a dozen of Yang Xin's students have returned to their hometowns half a month ahead of schedule.

More than 100 students from Laozhai Village Middle School also went to the county examination room to take the exam.

Because of its remote location, Laozhai Village Middle School has not been classified as a college entrance examination center, and Laozhai Village Middle School does not need to give the college entrance examination room, so other students in Laozhai Village are still in a normal state of class.
