"Between the ages of one year, the elders and young are similar, or when they are infected, they become cold and hot, and they are called epidemic malaria" - "Three Causes and One Disease Syndrome Formula".

Many people have heard of malaria, but don't know where its horror lies.

Academician Tu Youyou was awarded the Nobel Prize in Physiology precisely because of the extraction of artemisinin and the successful suppression of malaria.

It can be said that before the advent of artemisinin, malaria was basically incurable.

The transmission of malaria is also not directional, the ancients believed that malaria was transmitted through the air, but in fact, malaria is mostly transmitted by mosquito bites carrying malaria viruses.

In ancient times, getting malaria was equivalent to death.

The Chinese people talked about whether Alexander the Great would cross the Altai Mountains to come to Great Qin and compete with Qin, but unfortunately, Alexander the Great contracted malaria and died on the way to conquer India.

It was not only the Spartans who suffered from malaria, but also in China's ancient conquests.

When Emperor Wu of the Han Dynasty conquered Minyue, "there were many miasma, and the soldiers died of illness without blood"; The Eastern Han Dynasty led 8,000 Han troops to the south, but "the military officials died through the miasma in the 14th Five-Year Plan"; During the Qianlong period of the Qing Dynasty, several attacks on Burma were frustrated by malaria, and sometimes "before the battle, seven or eight out of ten soldiers died." ”

A large part of the reason for the lack of interest in attacking Indochina in ancient China was that it was easy to break out of malaria when the army marched to the southwest.

In modern times, when the Chinese Expeditionary Force came to Burma's aid, a large number of soldiers also died of malaria.

According to the "Four Humors Theory", the famous Roman physician Galen proposed that malaria is caused by an imbalance of body fluids, and can be cured by bloodletting and laxative therapy. However, malaria itself causes anemia, and simple and brutal bloodletting can only make patients die faster.

This is the reason for the medieval rumor that the West would only treat with bloodletting.

Traditional Chinese medicine (TCM) believes that malaria is the basic principle of malaria treatment. Malaria can be intercepted after malaria is diagnosed.

In the Eastern Han Dynasty, the book "Shennong's Materia Medica" records that the plant Changshan has the effect of treating malaria.

Li Yuan hurried to the isolation camp.

The quarantine camp has been sprinkled with lime powder according to the emperor's orders, and the camp tent has been isolated.

The intermittent groans of soldiers could be heard from time to time, and several doctors in masks walked around the tent door, their faces wistful.

"How's it going? Has the patient stabilized? Li Yuan was a little anxious.

Physician Zhao took off the white mask and asked the Emperor Taishang to take a step to talk, "Your Majesty's golden body, you must not go to the isolation camp, you are contaminated with malaria, which is a terminal disease that is difficult for the gods to treat." ”

"Am I just watching the soldiers die?" Li Yuan took a step to the side and said with emotion.

It suddenly occurred to him that malaria did not seem to be transmitted by air, as if it was a mosquito bite, and how do modern people spend their lives in the south?

There are many mosquitoes in the south, and if you want to get by, you need mosquito nets.

Mosquito nets have always been a must-have for marching.

Prevention is better than cure!

"Doctor Zhao, as far as I know, malaria is not spread by air or evil winds, but by mosquitoes in the south that carry "highly toxic"!

If you think about it, why there are so few people in the north who get malaria, because there are fewer mosquitoes in the north and more in the south, especially in the southwest, where the climate is warm. Li Yuan said.

"Your Majesty has a point." Doctor Zhao nodded and agreed: "During the treatment process, Weichen also found that the incidence of malaria among the soldiers who carried mosquito nets was indeed much less, and almost all of those who did not pull mosquito nets when they slept suffered from malaria.

Thousands of instructions, thousands of instructions, but until the moment of crisis, who will be serious, think that this disease will not come to their heads. “

Li Yuan shook his head with emotion, this is not a lesson that can be bought with money, you need to spend your life to buy it, he has already let the soldiers pay attention to it before the march, but there are not a few soldiers who disobey the yin and yang.

Everyone thinks that they are the protagonists in their lives, how can disasters happen to them.

In fact, part of the reason is that Li Yuan himself is not allowed to pull mosquito nets as the eight guidelines.

"Your Majesty doesn't have to be worried, Weichen has used the "Treatise on Typhoid Fever" recorded in the "Treatise on Typhoid Fever" to order the soldiers to go down and boil, and the Bupleurum Guiging soup needs Bupleurum chinensis, skullcap and reconciling the table, cinnamon branches, dried ginger, licorice, smallpox pollen and other medicinal materials,

However, the scarcity of medicinal materials in the army, which can only be consumed by 500 people, and because it is necessary to ensure the health of His Majesty and the generals, this is ...... Only 200 soldiers can be treated, but now there are at least 3,000 soldiers in the camp......

Others can save their lives for a while by taking miasma medicine first, but the most important thing is the lack of medical treatment. Physician Zhao hesitated.

In ancient times, when marching and fighting in a place where miasma was rampant, they would carry "miasma medicine", but this miasma medicine could not cure malaria, it could only make the body feel better, and the effect was very poor, and it was used with gold sore medicine.

"Then take out my share and treat them first, and then I will issue a holy decree to let the local government transport a batch of medicinal materials to the front line." Li Yuan smiled slightly, very generous, Bupleurum Gui ginger soup can only alleviate malaria, but cannot achieve the effect of radical cure.

In ancient times, it was difficult to treat malaria, and there were no less than 100 methods of traditional Chinese medicine research, but it was not clear why, among them, the Eastern Jin Dynasty hugged Puzi Ge Hong's "Elbow Reserve Emergency Prescription" was the best.

Hold the Artemisia annua, take two liters of water, wring the juice, and serve it.

The artemisinin developed by Tu Youyou is extracted from Artemisia annua.

Artemisia annua is very common, and it grows a lot in Yunnan-Guizhou places, so you only need to use local materials.

However, for the sake of insurance, Li Yuan combined the treatment with malaria powder of traditional Chinese medicine.

After all, there is only one life.

After that, Li Yuan returned to the camp and asked the pro-army to start collecting Artemisia annua in the nearby camp and boiling it into porridge for the sick and soldiers to drink together to prevent malaria.

However, under many measures, there were still soldiers who died suddenly that night, and when they woke up in the morning, hundreds of people died.

Artemisia annua can treat malaria, but the success rate is too low.

Fortunately, the soldiers who did not suffer from malaria survived the dangerous period of the malaria outbreak.

But on the twenty-third day of the siege and occupation of the city, when the city was about to be destroyed, the plague appeared again in the Tang army, and nearly half of the soldiers vomited and diarrhea, and their faces were pale and bloodless.

The whole battalion was wailing, and the entire Tang army even appeared war-weary, negative.

They even fear that they will die in a foreign land.

The pressure on the Emperor Taishang is also increasing, he doesn't want to be Yang Guang's second, and if he doesn't appease the soldiers, it is difficult to guarantee that he will not mutiny.

This war is no longer a victory between the armies, but whether the Tang Army can defeat the military disaster.

All the Central Plains dynasties were invincible in the face of these small southwestern states, but they were all defeated by the plague disease.

"Capture the city and don't unload the sword for three days!" Li Yuan promised coldly.
