I practiced medicine in ancient times

In the next few days, Bai Yan and Xu Qingyi kept an eye on the cows of Village Chief Niu. After a few days of observation and care, the cows gradually recovered and their appetites became better and better. Seeing this, Village Chief Niu was filled with gratitude that he could not express in words.

September passed and October came. The weather was getting colder and we had to put on cotton-padded jackets.

When Village Chief Niu saw that Xu Qingyi and Bai Yan were able to cure his cow's illness, he not only paid them back, but also inquired about their news.

It was known that the two of them were skilled doctors who specialized in treating poor people. They treated patients quickly, effectively, and at low cost, and they were well-known in the town.

When Village Chief Niu sees that a villager is sick, he will ask the villager to go to the town to see Xu Qingyi and Bai Yan for treatment.

As a result, the number of people visiting Xu Qingyi and Bai Yan for treatment has increased recently.

As for where the mother and daughter of the Li family are.

Ever since Mrs. Li drank the medicine prescribed by Xu Qingyi, soaked her feet and had a massage, she felt much more relaxed and energetic. She hadn't felt this good for a long time. She went to see Xu Qingyi every few days. Not only did she trust Xu Qingyi very much, she also stopped seeing anyone else for treatment.

Xu Qingyi and Bai Yan also gradually began to teach the villagers how to prepare a second kind of medicinal ingredient. After the villagers learned how to prepare one kind of medicinal ingredient and made a lot of money, they paid more attention to learning how to prepare the second kind of medicinal ingredient.

This also led to a huge increase in the purchase of medicinal materials in the clinic. While Manager Hou, Master Zhang, and Manager Hou were curious, they inquired and learned that recently there were many new faces who brought prepared medicinal materials to the clinic to exchange for money. They knew that these people were from the same village as Xu Qingyi and Bai Yan.

It was these two who taught the villagers how to collect and prepare medicinal materials, which led to a significant increase in the amount of medicinal materials purchased by their clinic recently, and a more complete variety.

"Are you making penicillin?" At this time, Xu Qingyi asked with a slight look in her eyes after seeing what Bai Yan was tinkering with.

Penicillin has a bactericidal effect and is used for pneumonia, tonsillitis, and anti-inflammatory effects after surgery.

If they had penicillin in ancient times, imagine if they had this powerful bactericidal drug, they would be able to save countless patients who would have lost their lives due to infection.

In ancient times, due to limited medical knowledge and backward medical conditions, many diseases were often fatal due to infection. For example, diseases such as pneumonia and tonsillitis, if not treated promptly and effectively, could easily lead to serious complications and cause death.

The emergence of penicillin made from white smoke will be able to provide patients with a new treatment method, enabling them to fight these diseases more effectively.

Especially in ancient wars, soldiers often faced the risk of infection due to injuries. If there were drugs such as penicillin, the soldiers' wounds would be better cared for and treated, greatly reducing the mortality rate caused by infection.

"Yes, I have been tinkering with this more than ten days ago. I didn't expect that I would finally figure it out." Bai Yan said excitedly at this time.

She also knew the significance of the creation of penicillin in ancient times.

However, Xu Qingyi also witnessed the birth of penicillin in this era.

The mold was removed by the white smoke, and she also used culture medium to cultivate it. She even made the distilled water for washing the charcoal herself, so now she can proceed to the next step.

The room they lived in only had some jars, cups, spoons, stirring sticks and other things on the table.

After everything was ready, Bai Yan first opened the nutrient solution he had prepared.

She then took out a small clay jar and sealed the top with her special sausage casing film, without using a lid. She cut a small hole in the film, took a funnel, put cotton in the funnel, and poured the cultured liquid over the cotton.

This step is used for filtering.

After filtering, pour an appropriate amount of rapeseed oil into the earthen jar and stir it continuously.

When you finish stirring, you will find that the liquid in the jar will be divided into three layers. At this time, you don't need to stir it anymore.

At this time, Xu Qingyi, who was watching Bai Yan making penicillin, was also treated as a tool and was ordered by Bai Yan to pass tools.

After that, Bai Yan used a small spoon to slowly remove the oil and fat on the top, leaving only the water at the bottom.

Then slowly add the carbon powder into the jar, stirring constantly again.

The reason why the charcoal is poured in is that the charcoal powder will absorb the penicillium components and the liquid in the jar will be absorbed. ?

After absorbing the carbon powder, take out the carbon and use distilled water. Do not use other water, otherwise it will be useless and will contaminate the washed carbon.

In order to extract distilled water, Bai Yan not only put in a lot of effort, but also worked for several days in a row.

Not only did he create a set of complicated tools to extract distilled water, he also spent most of the money he had saved to buy silver needles for Qingyi.

When extracting distilled water, ice cubes are also needed to assist in extracting distilled water.

Once the jar is drained of liquid, wash the carbon with a mixture of vinegar and water.

At this time, place a cup with filter cotton at the bottom to reduce the flow rate. Divide into multiple portions of 200cc each.

Use cotton to apply penicillin on a staphylococcal culture dish. If the staphylococci grow only around the penicillin applied after a few days, then the drug is effective.

There is no staphylococcus, but white smoke can also stain cotton with urine.

Afterwards, the grown penicillin is carefully picked out, and the production of penicillin is completed.

Once the white smoke has washed away the charcoal powder and the last step has been completed, it will only take seven days to see whether the penicillin production has been successful.

......

"What happened?" That night, Xu Qingyi and Bai Yan were suddenly shaken awake. Even the table in the room was shaking, and the things on it fell to the ground.

But then peace returned.

Within a few dozen breaths, the same vibration came again.

"The aftermath of an earthquake." Xu Qingyi and Bai Yan in the room looked at each other and immediately understood.

"We felt a strong tremor here. I guess it's not close to us. I don't know which place was unlucky." Xu Qingyi sighed.

"A lot of people will probably die in the earthquake." Bai Yan's eyes showed worry.

In the face of natural disasters and man-made calamities, human life seems so fragile and insignificant.

What's more, in ancient times when transportation and information were underdeveloped and medical conditions were even more backward, I'm afraid that many people were destroyed and killed in this earthquake.

"What happened?" The apprentices living in Courtyard C were also awakened by the aftermath of the earthquake, and they started chattering for no apparent reason.

"You're all free, right? Go back and sleep quickly. You'll be busy again in the future." Manager Hou came over from Yard A and scolded the apprentices and servants to go to sleep quickly.

However, he also knew what happened today, and a look of worry appeared on his face.
