Although Lao Zhu was happy in his heart, he still couldn't believe this eldest grandson, who was only eight or nine years old.

In his opinion, his grandson's remarks were simply nonsense and pure whimsy.

Lao Zhu suddenly thought of the conversation Queen Ma had with him last night, saying that the eldest grandson would ask her about smallpox as soon as she woke up.

It's simply incomprehensible.

This eldest grandson really had something to do with that terrible smallpox.

"Kid, you're so whimsical. The day of the flower virus has been ravaging people for years, and so many doctors have not been able to solve it throughout the ages, what can you do?! ”

Zhu Ying is still very calm.

"Grandpa, you didn't even have to eat back then, but you asked your friends around you to call you emperor and promised to take them to eat meat. At the time, they thought you were fanciful, but you didn't do the same!

Now, I just need one chance to prove to you that I'm right!

Otherwise, you call Imperial Physician Chen, and I can discuss this issue with him in depth in front of you.

If we can succeed, then our people of the Ming Dynasty will not be bothered by the smallpox disease in the future! ”

Lao Zhu still didn't want to believe Zhu Ying's words.

However, seeing his confident expression, it doesn't seem like a joke.

This grandson is really stubborn.

Lao Zhu smiled dotingly:

"Good boy, it's not small! I'll call Imperial Physician Chen over right now to cure your kid's problem!" ”

Zhu Ying smiled.

"Then call him quickly!"

Subsequently, Lao Zhu ordered someone to pass on Imperial Doctor Chen.

Although Zhu Ying does not know medical skills, he still understands the basic knowledge of smallpox.

Smallpox is a virulent infectious disease caused by the smallpox virus.

At the time of the onset of the disease, the infected person will be covered with a rash all over the body, then scab, and finally will leave a permanent scar on the face, commonly known as "pockmark", hence the name smallpox.

The smallpox virus is highly contagious and multiply, and can survive for months even after the death of a patient.

So, whether you have money or not, whether you are a man or a woman, old or young, as long as you are a human being, you can get smallpox.

The mortality rate from smallpox is about 30%.

Throughout human history, many nobles and even kings at home and abroad have died of smallpox.

The Kangxi Emperor of the Qing Dynasty was also disfigured by smallpox, leaving pockmarks on his face, from which "Kang Mazi" came from.

In ancient Chinese medicine, there was a basic method for treating smallpox: taking a decoction to detoxify and remove fire internally, and applying a medicine to reduce swelling and remove stasis externally.

However, the effect of the treatment is not very good in terms of the mortality rate of smallpox.

At that time, once people contracted smallpox, they had to resign themselves to fate.

The symptoms are mild and the body's immunity is good, and the pockmarked face is cured.

Those with severe symptoms and poor body immunity can only die with a whimper.

Therefore, in ancient times, people still focused on prevention of smallpox.

The ancients discovered a phenomenon in their long-term experience: those who have been cured of smallpox will never get smallpox again in their lives.

Although the ancients did not know the principle of immunology, its practical value is reflected.

As a result, the ancestors had the idea that if smallpox patients with mild illness could infect normal people, after the disease was cured, it would not cause death, but also give people the ability to live without smallpox.

This idea was put into practice, and a method of preventing smallpox was invented, the human pox inoculation method.

There are four specific operations: pox coating method, pox slurry method, dry seedling method, and water seedling method.

The human pox inoculation method first appeared in the Tang Dynasty, but at that time it was only circulated in a small range of people.

It was first promoted at the official level during the Longqing period of the Ming Dynasty, and it was not until the Kangxi period of the Qing Dynasty that it was fully popularized.

Its widespread use greatly reduced the smallpox mortality rate in the Qing Dynasty, which also became an important factor in the skyrocketing population of the Qing Dynasty.

Later, this method gradually spread overseas, spreading to Europe and the Americas.

The human pox inoculation method originated in China and has made an indelible contribution to the fight against smallpox, saving at least hundreds of millions of lives.

This is enough to prove the power of Chinese medicine!

It's just that later generations have lost the essence of Chinese medicine left by our ancestors.

Unfortunately, vaccination is not completely safe, with a mortality rate of about 2% and often leaves some sequelae such as tinnitus.

Later, a village doctor in the Yin Kingdom accidentally discovered that cowpox could prevent smallpox. After years of research and experimentation, the vaccinia inoculation method was finally invented.

The biggest advantage of the vaccinia inoculation method is that the safety is greatly improved.

Because after being infected with cowpox, in addition to causing mild lymphadenitis, it will not cause acne, let alone fatal.

Later, the vaccinia inoculation method became popular, and gradually, smallpox was completely eliminated.

Following in the footsteps of his ancestors, it was much easier for Zhu Ying to do this in the Ming Dynasty.

Just use the cowpox inoculation method and experiment with death row inmates.

Zhu Ying felt that if he told Lao Zhu about this method, Lao Zhu would definitely think that it was a fantasy.

Therefore, it is necessary to find a professional person to discuss and then implement it.

It didn't take long for Imperial Physician Chen to be taken to the Fengxian Palace.

"Your Majesty! I wonder what Lao Chen can do for you? ”

Lao Zhu gently touched Zhu Ying's head and said jokingly:

"Imperial Doctor Chen came just in time! Take a good look at this eldest grandson of mine. His physical problems seem to be gone, but there are a lot more problems in his head. ”

Imperial Physician Chen could hear that Lao Zhu was joking.

"Hehe, it seems that Your Majesty is in a good mood today!"

"Haha, good grandson! Tell Imperial Doctor Chen yourself! ”

Only then did Imperial Physician Chen react, it turned out that the eldest grandson of the emperor was looking for him.

"Oh, yes! The eldest grandson of the emperor wanted to ask the ministers any questions before, but then the two emperors and grandsons had an accident and walked away. It's because I'm so confused that I forgot about it, and I hope that the emperor's eldest grandson will forgive me! ”

Zhu Ying smiled:

"Imperial Doctor Chen, you're welcome! I'm not going to beat around the bush with you, I'll tell you straight! Regarding the prevention and treatment of smallpox, have you ever used the "human pox inoculation method"? ”

These words made Imperial Physician Chen look confused.

Imperial Physician Chen is over 70 years old this year, and he is in charge of the Imperial Hospital in the palace, and he is an experienced old doctor.

However, when he heard the emperor's eldest grandson blurt out the word "smallpox", he couldn't help but shudder.

He asked with a look of disbelief:

"Smallpox? How to inoculate against human pox? Why did the eldest grandson of the emperor suddenly ask about this?! ”
