Doctor of the Great Song Dynasty: In the beginning, Li Qingzhao and Li Qingzhao made a private decis

Chapter 392 Fan’s Disinfection Method

"See Madam!"

In the Fan Mansion, the servants all said respectfully when they saw Ma.

Ever since Mrs. Ma was promoted from concubine to head wife by official decree, everyone understood that the Mrs. Fan of yesterday and the Mrs. Fan of today have completely different meanings.

Before that, the Fan family called Mrs. Ma more of an honorific title. However, everyone knew from the bottom of their hearts that Mrs. Ma was just a concubine of the Fan family, and there was no difference between her status and that of a servant.

Although Ma was appointed by Fan Chunli to take charge of the Fan family's inner house, it was Fan Chunli's order, and he also withdrew it with one word. Later, with the rise of Fan Zheng, Ma was increasingly respected both inside and outside the Fan family.

But now the Ma family can be regarded as the real mistress of the Fan family, both in name and in fact.

"Okay, let's all get busy!" Ma said with a kind face.

Today, Fan's mansion is full of laughter and laughter, and the atmosphere is harmonious.
Even if a servant in the family makes a mistake, although Ma has a good temper, he will still scold him, but now he will just wave his hand and let him go.

What she usually loves most is holding her grandson in her arms, showing off to her good friends’ wives with pride, and smiling from ear to ear. The effect of intergenerational kinship is vividly displayed on her.

However, today, not long after Ma left, he came in with Fan Zhi in his arms, who was crying loudly, and pointed at Fan Zheng and scolded him.

"You bastard!"

"Mother, why did the child offend you again?" Fan Zheng asked in confusion. His mother had just come back in a good mood, so why did she suddenly scold him again.

Ma angrily put Fan Zhi, who was crying, into Fan Zheng's arms, and snorted coldly: "Look at the good things you have done!"

Fan Zheng comforted his crying son and said disapprovingly: "Mom, it's normal for children to cry, and they are not sick!"

With Fan Zheng's medical skills, he easily diagnosed that his son was currently very healthy and had no disease.

However, after Fan Zheng coaxed him for a long time, he found that Fan Zhi was still distressed, which puzzled Fan Zheng greatly.
"You're not sick, you're hungry." Ma said angrily. The child couldn't speak. Once he was hungry, he could only cry.

"Hungry? Then breastfeed!" Fan Zheng said confused.

At that moment, Fan Zheng handed Fan Zhi to Li Qingzhao. In this era, the infant mortality rate was very high. Doctors advocated breastfeeding, and the Fan family naturally followed this practice. Li Qingzhao fed Fan Zhi himself.

Li Qingzhao lowered his head and said with a blushing face: "I have just fed you, and I don't have much milk left."

"You're still hungry after feeding?" Fan Zheng couldn't help but be stunned. His eyes couldn't help but wander back and forth between Li Qingzhao and his son. He didn't know whether his son was able to eat, or whether Li Qingzhao was poor!

"You're still looking around, please be careful in the future." Ma grabbed Fan Zheng's ear and said bitterly.

"what!"

Fan Zheng suddenly realized that it was his mother who suspected that he had stolen his son's food rations.

When Li Qingzhao heard this, his face suddenly turned red with embarrassment. He didn't know how to explain it and could only lower his head helplessly. This further confirmed Ma's suspicion.

"My mother taught me a lesson! The child will not dare to do it next time."

Fan Zheng quickly admitted his mistake and came to Li Qingzhao's rescue.

Ma finally let Fan Zheng go and said bitterly: "Why don't you coax her quickly and find a wet nurse for your mother?"

Although breastfeeding is the best for babies, now Li Qingzhao can't supply Zhao Zhi at all, so he has to find another wet nurse. However, he can't find one for a while, so Fan Zhi can't be left hungry all the time!
"Mom, wait a minute! We can't find this wet nurse," Fan Zheng quickly stopped Ma and persuaded her.

"Why?" Ma frowned.

Fan Zheng explained. "It is best to breastfeed the baby not only because the mother and child are of the same mind, but also because the mother and child are one body and will not be infected by various sources of disease. After all, the wet nurse is an outsider and is not one with the child. In addition, she often goes out to the outside world, and it is easy to Bringing in external sources of disease and causing cross-infection is not good for straight children.”

"Then what should we do? We can't let Zhi'er go hungry! Besides, Zhi'er can't eat complementary food now." Ma said worriedly.

The so-called kiss of another generation, Ma finally had a grandson, so she naturally didn't want her grandson to go hungry. If Fan Zhi was older, he could still eat some complementary food, but now the only way to go is to breastfeed.

Li Qingzhao reminded in a low voice: "Instead of hiring wet nurses, people will drink cow's milk and goat's milk to raise their children."

For the sake of Fan Zhi, Li Qingzhao gained a lot of knowledge about child care, and also had some experience in raising children among the people.

Fan Zheng shook his head and said: "Whether we hire a wet nurse or use cow's milk or goat's milk, we can't escape one difficulty, that is, infection with various sources of disease will cause danger to the babies, and even many babies will die in infancy. There are so many reasons. "

"This is happening!" Ma was suddenly shocked.

It was not easy for the Fan family to have a grandson. If he had been frail and sick since he was young, he might not be able to take care of himself if he had a father who was an evil doctor.

Lian'er on the side suggested: "My uncle is afraid that the source of the disease will harm the young master, so why not use high-temperature sterilization to boil the milk like Lian'er makes ice cream?"

Fan Zheng nodded slightly and said: "This is indeed a method. However, once the milk is boiled, the nutrients inside will be destroyed. Although it can feed the baby, it is not as good as real breast milk."

Li Qingzhao sighed: "It would be great if there is a way. How can we worry so much? Let's feed Zhi'er first. At worst, I can just eat more in the future."

For the sake of the child, Li Qingzhao no longer cared about his figure at this moment and decided to gain weight in order to produce more breast-feeding food.

"No! Maybe there is a way to get the best of both worlds."

Fan Zheng's heart moved, and he thought of the famous pasteurization method for milk in later generations.

This time, he will also perform Fan's disinfection method.

"The best of both worlds? Don't make any mistakes!" Ma's heart tightened when he heard this, and he quickly warned Fan Zheng.

"Don't worry, mother, the child will not harm Zhi'er. Lian'er, go get some fresh milk! I'll be of great use." Fan Zheng immediately ordered.

"Yes! Uncle!" In order to make ice cream, Lian'er raised a lot of cows. Now that ice cream is unsaleable in winter, there is already a large amount of milk left. Soon, Lian'er got a large can of fresh milk.

At this moment, Fan Zheng took the fresh milk, poured it into a glass, closed the lid, and began to heat it over low heat.

At that moment, a faint milky fragrance filled the whole room. Fan Zhi smelled the smell and hurriedly looked around.

Li Qingzhao sighed helplessly upon seeing this, thinking that Fan Zheng still chose the high-temperature sterilization method to make milk.

Although high-temperature sterilized milk loses a lot of nutrients, it is safer and can supply Zhi'er in large quantities to keep him full. This is already the best solution at the moment.

However, Fan Zheng did not increase the intensity of the fire, but kept the milk at a higher temperature without letting it boil.

"Master, why is this happening?" Lian'er asked in confusion. This is completely different from Fan Zheng's usual high-temperature disinfection method. What if the disinfection is not thorough and the young master gets sick?

Even Li Qingzhao and Ma Shi frowned and looked at Fan Zheng in confusion, but they believed that Fan Zheng would definitely not do anything harmful to Zhi'er.

Fan Zheng explained: "All disease sources are also a kind of life. Since they are life, there are two ways to die. One is direct high temperature, which causes the disease sources to die in a short period of time to achieve the purpose of disinfection."

Li Qingzhao nodded. The high-temperature disinfection method that Fan Zheng was most proud of allowed doctors to find a weapon against the plague.

"There is another method, which is to keep the milk at [-]% high temperature without boiling without directly heating it. Such a high temperature is no longer suitable for the survival of pathogens, but it is not boiling at a high temperature, but it can maintain nutrients to the greatest extent. This method is the only one The disadvantage is that disinfection is very slow and requires two sticks of incense to wait." Fan Zheng said solemnly.

"Two sticks of incense." Li Qingzhao nodded slightly. Although Fan Zhi was hungry quickly, even if he couldn't feed him enough, he could still last for half an hour. Two sticks of incense were enough time.

At the moment, Fan Zheng carefully controlled the heat. The time of two sticks of incense passed by in a flash. Soon, the fresh milk was sterilized.

After stopping the heating, the milk needed to be cooled to a suitable temperature quickly. Taking this opportunity, Fan Zheng extracted some milk and observed it under a microscope. Sure enough, he found that the milk at this moment had been completely sterilized.

"Fan's disinfection method is a great success, and we can feed Zhi'er now." Fan Zheng said assuredly.

Now Fan Zheng made a simple baby bottle, sterilized it at high temperature and started feeding Fan Zhi.

Fan Zhi, who was already hungry, swallowed in large gulps. When Fan Zhi drank enough milk, Fan Zheng deftly burped him, and then he fell into a satisfied sleep.

"With this method, Zhi'er no longer has to worry about being hungry." Ma finally felt relieved when she saw that her precious grandson was no longer hungry.

"If this method is spread, all babies in the world will grow up healthily."

Li Qingzhao turned his eyes and immediately understood the significance of this disinfection method. Hiring a wet nurse is not cheap, and there are very few families who can afford a wet nurse. Moreover, according to the doctor's philosophy, breastfeeding is the best, and using a wet nurse to feed babies can cause infections. Risks from various sources of disease.

If the combination of breast milk and cow's milk is used, it is enough for the baby to grow healthily, and there is no need to worry about the risk of infection.

"More than that, ordinary breastfeeding can only last until one year old, and at most two years old, but with cow's milk, it is enough for children to eat until they are six years old, and even older. In this way, children's bodies will be stronger , with stronger resistance, the survival rate of children will be higher." Fan Zheng said solemnly.

"Then our straight son will definitely grow up healthy." Li Qingzhao looked at his sleeping son tenderly, with a look of love on his face.

In this era, not to mention the Fan family, even the royal princes and princesses have an alarmingly high mortality rate. Being able to ensure that his children grow up healthily is Li Qingzhao's greatest wish.

"Uncle, since long-term consumption of milk has such benefits, and Lian'er still has some surplus milk, can we use this method to supply fresh milk to the people of Kaifeng?" Lian'er asked with excitement.

During the hot summer, she could make a lot of money by running an ice cream shop. However, the ice cream business only thrived in the summer and was bleak in the winter. The cows had to be raised all the time, so a lot of milk was wasted. If Fan Zheng was used The unique low-temperature sterilization method not only retains the flavor and nutrition of milk, but also avoids the sources of disease caused by drinking raw milk. This will definitely be a good business.

"Yes, Kaifeng City is the place where the richest man in the world is located. Naturally, he attaches great importance to future generations. And as long as he treats children well, I believe there will be countless families buying fresh milk. This kind of business is far more promising than ice cream." Fan Zhengdian said. Nodding, Lian'er now had a businessman's keen sense of smell and quickly discovered this business opportunity, which surprised him greatly.

"Thank you for the advice!" Lian'er was immediately excited. Kaifeng has a population of one million, and there are more families with children who can afford to consume. Although they can't afford a wet nurse, they can definitely afford milk. If she can supply milk to Kaifeng City , this will be a year-round business, which is better than just the ice cream business in the summer.

"Kaifeng City has a population of one million, and there are many children. The demand is extremely high, but with your dozen or so milk-producing cows, I'm afraid there won't be enough supply." Fan Zheng pointed out.

Lian'er thought for a moment and said: "Farmers raise a lot of livestock inside and outside Kaifeng City. Lian'er now has enough money in her hands to buy a cow. If it's not enough, she can buy milk from surrounding farmers."

Fan Zheng shook his head and said: "No! I suggest you not to cooperate with farmers to purchase milk. Even if you add twice as much water to a glass of milk, there will still be no difference in appearance. Farmers will actively adulterate it for their own benefit. When the time comes, , your reputation is ruined and you are unable to defend yourself."

Lian'er's face suddenly changed. According to her original plan, she wanted to occupy the Kaifeng market in a short time and cooperate with farmers. After Fan Zheng reminded her, she found that this was simply a way to die.

"what!"

Lian'er was immediately discouraged.This is a business that makes a lot of money every day, but unfortunately she is too weak to sustain it.

Li Qingzhao on the side saw this scene and couldn't help but said: "My husband always has ideas, why not help Lian'er."

Li Qingzhao and Lian'er were sisters, so naturally they were particularly concerned about Lian'er's affairs. Besides, her straight son also needed fresh milk, which could kill two birds with one stone.

Fan Zheng nodded and said: "Contact Pang Jizu about this matter. He is in charge of the veterinary line. He will definitely be able to find a large number of cows for you. First, establish a foothold in Kaifeng City, and then cooperate with the veterinary line to cultivate more cows in the future." dairy cow.."

"Thank you, uncle!" Lian'er said with great gratitude.

Fan Zheng said solemnly: "The reason why I help you is to let babies all over the world drink healthy milk and let babies in Song Dynasty grow up healthily. This is also my advice to you."

There have been countless cases of milk accidents in later generations. Fan Zheng now decided to take precautions from the beginning to prevent future generations from poisoning babies.

"Lian'er will follow my uncle's teachings and will not let the young lady down." Lian'er solemnly promised.

Lian'er got the cure and left impatiently.

"My husband is a great talent. Not only has Zhi'er been fed and clothed, but babies all over the world no longer have to worry about hunger." Li Qingzhao looked at Fan Zheng with admiration. With the Fan family's ability, it is easy to feed a baby. What is commendable is that Fan Zheng Just found a way to feed babies all over the world.

"The art of healing the country!"

For the first time, Li Qingzhao personally experienced the magic of Fan Zheng's medical skills.
