Physician of the Song Dynasty: Zhang Kai and Li Qingzhao have a private life-long contract

"Sulfur soap for mite removal!"

Li Qingzhao is a leading high-heeled fashionista in Kaifeng City. He is also the leader of Yizhuang and has great influence.

When he took the initiative to promote sulfur soap and toilet soap, he immediately attracted the attention of many dignitaries and ladies.

"This thing can really get rid of mites?" Many ladies asked in surprise.

"Of course! This is what I specially made by pestering my husband." Li Qingzhao said proudly.

However, the thought of Fan Zheng asking her to do those embarrassing gestures for the sake of soap immediately made her face blush.

"Then let's give it a try!" All the ladies and noble ladies said excitedly.

After all, no one wants to have their face covered with bugs, and mites can also cause acne. Now many people are trying sulfur soap and soap.

However, as soon as everyone used soap, they were immediately conquered by the magical soap. In addition, soap has many wonderful uses. In addition to sulfur soap, soap can remove mites, soap can wash hands and bathe, and soap can do laundry. Once launched, it became popular throughout Kaifeng City.

At the moment, Li Qingzhao took advantage of the situation and asked Kaifeng Yizhuang to prepare for the soap workshop, and worked overtime to start producing soap.

"How could it be such a coincidence! Just when doctors announced the discovery of mites, Yizhuang created sulfur soap to remove mites!" Some people couldn't help but be jealous when they saw Yizhuang making money every day.

However, as a piece of news came back from the south, the doctors were immediately cleared of their grievances. The doctors used a microscope with 800 times magnification to find out the cause of potbelly disease. It turned out to be an invisible insect with an even more terrifying name - —Schistosomiasis.

"Pot-belly disease has been officially renamed schistosomiasis! The host of schistosomiasis has also been identified, and that is the snail, which is very common in the south."

As soon as this news came out, the city of Kaifeng was in an uproar. The discovery of schistosomiasis in potbelly disease in the South further confirmed the theory that the causes of the disease are alive. Nowadays, no one doubts mites anymore.

In the city of Kaifeng, there are also many tourists from the south who know a lot about pot-belly disease, and even talk about it in a negative light.

Once a person is infected with potbelly disease, his limbs will become thinner and his belly will become enlarged. The person will eventually suffer for a lifetime. There are countless people in the south who are infected with the disease, and the harm is great.

Snails are a common food in the south. Many times when there is famine, many people even take the initiative to catch snails and eat them. Who would have thought that they are the main culprit of potbelly disease.

"I would like to inform the officials that according to medical research, snails are the only host of schistosomiasis. We also request the court to order a ban on eating and selling snails. Whenever snails are found in rivers and lakes, warnings must be set up and entry into the water is strictly prohibited," Su Song asked. .

Zhang Dun frowned and said: "This method is certainly feasible, but I'm afraid it won't work. There are many paddy fields in the south, and many paddy fields contain snails. Maybe we need to use corresponding water sources. Do the people have to abandon the fields in order to prevent and control schistosomiasis?"

Zhang Dun is also from the south, so he naturally knows the customs of the south. In addition, the labor service has now spread to the south of the Yangtze River. If it is due to schistosomiasis, it may cause more trouble.

Su Song suddenly frowned. The safety of the people on one side and the livelihood of the people on the other were indeed a dilemma.

Seeing this, Fan Zheng held up his hands and said: "There is no way to solve the problem of schistosomiasis and preserve the paddy fields. That is to mobilize a large amount of manpower and material resources to eradicate the snails in key waters."

“Eradicate the snails!” Many southern officials exclaimed.

You must know that snails are widely distributed in the south and reproduce at an alarming rate. It is very difficult to eradicate snails.

Fan Zheng nodded solemnly. In later generations of China, there were several large-scale artificial eradication operations of snails, which finally curbed schistosomiasis, which has been responsible for thousands of years.

"Although this method is stupid, it is an effective method. Of course, even so, it is impossible to completely eradicate schistosomiasis. At the same time, doctors will also study drugs to treat schistosomiasis to eliminate the disease among the people." Fan Zheng said solemnly.

All the officials couldn't help but sigh, fearing that the South would have to add another heavy task - removing snails.

"allow!"

Zhao Xu waved his hand.

Pot-belly disease is very harmful and is even getting worse. Now that doctors have found the cause of pot-belly disease, the sooner it is eradicated, the better.

As the imperial court passed a plan to prevent and control schistosomiasis, the existence of mites was once again confirmed, which made Yizhuang's soap business boom again.

Since the fat source of soap is mainly lard, it even indirectly drives up the price of pork.

The price of pork has risen many times, which even alarmed Shen Wang Zhao Bi. When he learned the reason, he immediately found Fan Zheng.

"Don't worry, Prince Shen! Soap has just started. Most people in Kaifeng don't like fatty meat. Lard is cheap, so soap workshops give priority to pork as raw material. When the price of pork rises, soap will naturally choose other oils." Fan Zheng explained .

In Kaifeng City, although the custom of pork as cheap meat has changed, there is still a prejudice, which results in the price of pork being low. In addition, Kaifeng City is the land recovered by the Song Dynasty, and there is no shortage of fat and fatty lard. It's not popular, and fat meat is cheaper.

In addition, lard is easy to solidify, and saponified soap is easy to shape. This is why soap workshops use lard as the preferred raw material.

"Fan Taicheng's actions, the king is naturally relieved." Zhao Yan said with a sigh of relief.

The situation in the palace has been turbulent recently. As a prince, he naturally does not want to make a big splash at this moment.

Fan Zheng nodded and said: "In addition to lard, the doctor also has a project that he wants to cooperate with King Shen."

"Is there still cooperation?" Shen Wang Zhaobai raised his eyebrows.

Fan Zheng nodded and said: "Yes, the doctor is planning to buy the pig hair after slaughtering in the pig farm!"

"Pig hair?" Zhao Bai couldn't help but be surprised. Pig hair is discarded from pig farms, and the doctor is actually planning to buy it?

Fan Zheng nodded and said without hesitation: "The doctors are preparing to enter the field of personal care. They found that most people use items such as willow branches to keep their mouths clean, which is extremely inconvenient and cannot be brushed clean at all. After research, the doctors made a toothbrush and found that pig bristles Wool is the best material.”

"Brush your teeth with pig hair?" Zhao Bai couldn't help but twitched his face. Everyone in the world believed that pigs were unclean. Fan Zheng first changed the Song Dynasty's prejudice against pork, making pork widely accepted by people all over the world, and smelted it with lard. Soap, and now toothbrushes are made from pig bristles, and emotions are treasures all over the pig.

Fan Zheng nodded solemnly and said: "Pig hair is moderately soft and hard. It is then sterilized by doctors at high temperatures, cleaned and made into toothbrushes that are cheap and affordable. They will surely enter thousands of households in the Song Dynasty in the future."

After being forced to make soap, Fan Zheng accidentally discovered that Da Song was almost blank in the field of personal care, so he naturally followed suit.

Coupled with the fact that doctors are in urgent need of money for their recent expansion, these personal care products will definitely provide a steady stream of money for the expansion of doctors and become a boost to their prosperity.

And Zhao Bi also couldn't help but smile wryly. He didn't even think about making money when raising pigs, but now he is forced to make a lot of money.
