The land of South Vietnam has been communicating with the Central Plains culture for thousands of years, why has it not been able to develop?

In the final analysis, the living conditions were not improved, and there were many poisonous insects in the land of South Vietnam, and the weather was prone to plague all year round, which was not solved until the Ming and Qing dynasties.

"Infected?"

Sun Xiangfu said a word in a hurry, but it aroused Feng An's interest.

"Well, it's a pathological feature similar to the invasion of wind evil." Sun Xiangfu couldn't explain the meaning of this word to Feng An, so he casually gave an example.

"Do you still know medicine?"

If there is anything that is most lacking in the land of Nanyue, of course, it is doctors, but how poor are the doctors in this period to get mixed into a wild place like Lingnan?

Therefore, at this time, many of the Lingnan tribes and Yiren tribes believed in witch doctors, and the level of witch doctors, thinking about it, was more to kill than to save lives.

"Although the lower official does not understand the method of healing, he can think of a way with the Yue Gong, and there are some simple prevention methods, if the Yue Gong feels that it should be used, the lower official can organize it into a book and hand it over to the Yue Gong." As a child who grew up in the south, Sun Xiangfu has some common sense that later generations of government propaganda are there.

Feng Ang was overjoyed when he heard this, and immediately asked a few thin farmers with big bellies among the people to step forward.

"This is the most common potbelly disease in Lingnan, what can you do?"

"Potbelly?"

Sun Xiangfu recognized the symptoms of these people at a glance, which is the most common schistosomiasis in the south, in the first decade of the twentieth century, the number of people suffering from schistosomiasis worldwide reached more than 200 million, and then the government promoted a large-scale eradication of schistosomiasis, which was slowly controlled.

Sun Xiangfu is a person born in which era, when he was a child, he loved to play in the water in the summer, often went down to the river to swim, and also suffered from schistosomiasis, he had to eat a lot of pills every day, and he hated those medicine bottles, until now, he still roughly remembered some eye-catching marks on those medicine bottles, the main medicine seems to be Artemisia annua, white myrtle, soft-shelled turtle, salvia, red medicine, etc., but there were also some people with strong bodies at that time, and they could also alleviate the condition directly with croton.

"There may be a cure for this disease, but we need to try it slowly."

Potbelly disease is a terminal illness for people in this period, even if there is a direction of treatment, it is also a blessing in misfortune, of course, in later generations, schistosomiasis to the advanced stage, but also more dead than alive.

The three thin farmers roughly understood Chinese, and knelt on the ground when they heard the rumble, and then their families also knelt on the ground, and finally, the whole farmer knelt on the ground, and Sun Xiangfu was a little blind.

"If Zhengming can cure this disease, you will be the benefactor of hundreds of thousands of people in my Lingnan, no matter what, you must do your best."

Hearing Sun Xiangfu say that it might be cured, Feng An's eyes immediately turned red, this big-bellied disease is the first major harm that restricts the reproduction and growth of the Lingnan population, every year, at least thousands of people are killed by this disease, reaching more than two percent of the total population.

"My lord, my lord, please save my father!" After a while, the little girl with braids running out of the crowd with tears in her eyes, pulled Sun Xiangfu's sleeve and said.

She is a relatively intelligent child among the Yi people, and she usually listens to some Han people in the city to speak Chinese, and after listening to it more, she learns Chinese herself.

"Everyone, please get up, this can't be done, although I am somewhat sure, but I still need to repeat the trial, everyone don't kneel to me, there are leeches on the ground······"

No matter how Sun Xiangfu shouted, many people refused to get up, and finally Feng Ang spoke, and everyone got up one after another.

"Little girl, what's your name, can you tell me who your father is?" Sun Xiangfu touched the little girl's head and said amiably.

"My name is Ah Yue, this is my father, everyone calls him Ah Shan." The little girl pointed to a shriveled man with a big belly.

"What about your mother?" Sun Xiangfu tried to find a woman from the crowd, but found that when he asked this question, the little girl's tears were even more turbulent.

"My mother died of a potbelly disease, and so did my brother, if my father dies again, I will have no relatives, woo woo woo ······" Although the little girl is not very old, she also knows that the person who suffers from the big belly disease will die, and it should not be long before her father will die.

"Okay, I promise you, I'll do my best to heal your father."

Sun Xiangfu touched the little girl's head and comforted her, and then arched his hand to Feng Ang, "Yue Gong, please gather these potbelly patients together as much as possible, and after the prescription is determined, let people start to test the medicine, which may be dangerous, but there should always be some people who can be cured, so whoever tries the medicine first, please also ask for their wishes." ”

Feng Ang agreed without thinking about it, "Okay, leave this matter to the old man, Zhengming have any needs for medicinal materials, just tell the old man, go up the mountain and down to the sea, and the old man will help you find it." ”

"In that case, let's split up!" Sun Xiangfu nodded, and then no longer delayed time, and took his group to the city.

"Amitabha, the poor monk also has a rough understanding of pharmacology, how can there be no poor monk when an adult does this great compassionate thing." Xuanzang followed Sun Xingfu's footsteps and said a Buddha horn.

"Master, in this way, I am afraid that this matter will delay your journey to the west to learn the scriptures." Sun Xiangfu said with a difficult face when he heard this, he had promised Xuanzang before that he would send him to Tianzhu.

"Hehehe, how can the matter of learning scriptures be as important as the Tang Dynasty." Xuanzang smiled with relief.

"The Qi Huang technique of the poor road is not bad, and it can help you." Li Chunfeng, who has been playing with pigeons for the past few days, also appeared on the other side of Sun Xiangfu at this time.

Sun Xiangfu looked at the two people beside him, and said with a smile, "Hehe, at this moment, do you think the religion you believe in is useful?" ”

The two were silent until they returned to the city after walking for an hour, and they were still troubled by the questions raised by Sun Xiangfu.

Sun Xiangfu did not bring many emergency medicines on the ship, but there were pharmacies opened by Han people in Guangzhou, and they opened their shops here, not to sell medicines, but to collect some Lingnan herbs to sell in the Central Plains, so there were not many types, at this time Feng Ang had already sent a team of soldiers to the pharmacies, and here, it was forcibly requisitioned by him.

"Damn, my brother doesn't recognize Chinese medicine."

Seeing the cabinets full of roots, bark, withered grass and the like, Sun Xiangfu almost beat his head, although he is engaged in plant research, but he really doesn't recognize several herbs, and there are no graphic signs on the bottles of the medicines he ate when he was a child.

"That, master, do you know a Chinese medicine called Bai Wei?"

For the edible Artemisia annua, Sun Xiangfu knows, then, the soft-shelled turtle is not to mention, there are at least three kinds of medicinal materials left Sun Xiangfu does not know if he can correspond to the name of this period, because this period due to regional problems, a traditional Chinese medicine, often has many other names, the south and the north are not the same, at this time there is no detailed explanation of the pharmacology of the "Compendium of Materia Medica" for comparison, of course, even if there is, Sun Xiangfu does not understand.

"Bai Wei?" Xuanzang was stunned when he heard this.

"Also, salvia and red medicine." Sun Xiangfu also knew the two kinds of artemisia annua and soft-shelled turtle that could be eaten, the other three flavors, and the medicine that he might have forgotten, so he didn't know.

"Red medicine poor Dao knows, in Chang'an it is called peony." Li Chunfeng interjected.

"This Bai Wei, could it be the Wei Cao mentioned in Shuzhong?" Xuanzang thought about it before guessing.

"Whether it's or not, I'll try it as you say, and do you know about salvia? It's just a kind of red root" Sun Xiangfu suddenly thought of the Danbao Xinxin tea he bought for his mother once, and asked the two of them again.

"My lord, let's see if it's it." The shopkeeper of the pharmacy took out a wooden box, which was full of sun-dried red roots.

"yes, that's it." Sun Xiangfu saw the real thing and said happily.

In fact, salvia is recorded in the Qianjin prescription of the medicine king Sun Simiao, but at this time, Sun Simiao should not have written a Qianjin prescription.

Then, the next question comes, even if the required medicinal materials are collected, how to proportion, and the dosage of the problem, this is only a professional doctor, Sun Xiangfu himself, since he was a child, he has never even decocted Chinese medicine.

However, Xuanzang and Li Chunfeng said that they know pharmacology, Tongqi Huang, that is not blown, the serious monks and Taoist priests of this period all know some medicine, they usually get sick, and they are also their own doctors, so Sun Xiangfu asked them to study the medicinal properties, anyway, as long as they don't eat too much, they should not die.

After making a list for Feng An, looking for these medicinal herbs has become the biggest thing in Lingnan now, Sun Xiangfu thought about it for half the night in his guest room with his memory, and then wrote down all the precautions he knew for the prevention and control of schistosomiasis.

Early the next morning, Sun Xiangfu was taken by Feng Ang to a concentration camp for potbelly patients.

"This, how can there be so many sick people?"

Sun Xiangfu looked at the hundreds of people in the barracks with some surprise.

"This is still the patients that the old man collected in one day, there are at least thousands of patients in the whole Lingnan, and besides, they died this year, and there will be so many more next year." Feng Ang said with a heavy face.

Hearing this, Sun Xiangfu figured out why the population of Lingnan has not risen for so many years, the population base of hundreds of thousands, the maximum number of newborns every year is 10,000, and thousands of deaths of schistosomiasis alone are a year, plus the people who die from other reasons, it is fortunate that the population can barely be maintained.

"The matter of drugs, in addition to collecting, also needs to be slowly tested, before that, I hope that Yue Gong can implement military control over these patients, and in addition, let more patients with potbelly disease come to this concentration camp." Sun Xiangfu said, and handed the things he had written last night to Feng An.

"There is so much attention to being paid to curing this disease?"

Feng Ang saw a few large pieces of paper densely packed with words, suddenly his head was as big as a bucket, if it was according to what was said on the paper, he had a lot of things to do, the simplest light, let everyone drink boiled water, prohibit eating raw food, and bury all the feces deep or burn them in a fire, which can only be completed by the army organization, because in the hot weather in Lingnan, the people do not have the habit of cooking things to eat and drink, and generally eat more raw and cold food.

Of course, Lingnan people themselves have also summarized some safe eating habits, but in Sun Xiangfu's view, those are still unsafe, and then there are clothes, water treatment after the patient's washing, etc., there are also many requirements, Sun Xiangfu added the word "must" after each article, so that Feng Ang had to be cautious.
