Daming: The system rejected my request for salted fish

For example, if you change the humid, dirty and messy environment, the cockroaches will disappear.

Modern medicine is to use a bottle of DDT to directly poison, but this poisoning method is also limited.

For example, a cold is actually an inflammation, an inflammation of the nasal cavity or throat, commonly known as an upper respiratory tract infection.

For 80 percent of viral colds, humans are actually helpless.

Medicines only relieve physical discomfort, not kill pathogens. They rely on the body's own immune function to heal itself.

The remaining 20 percent are bacterial colds and can be treated with antibiotics.

The human body is strong, but also weak. Sometimes, even with Chinese medicine, it is unable to fight all inflammation.

At this time, some modern medicines are needed to make up for this shortcoming.

The three types mentioned by Wei Wu all have very good effects on inflammation.

However, for these imperial physicians, these three medicines can only be said to be both familiar and unfamiliar.

They know the meaning of garlic, but they don’t understand when the word “vegetarian” is added. They also know the meaning of willow, but they are confused when the word “sour” is added.

Finally, they also understood the Penicillium mold in penicillin. By the same token, adding a vegetable would be enough to stop it.

Just as the imperial physicians were about to continue asking questions, Imperial Physician Xu spoke first.

"Uncle Changle, are the three medicines you mentioned extracted from the substances their names represent?"

"That's right!"

Wei Wu nodded and secretly praised in his heart: No wonder he can be the imperial physician, his ability to grasp the key points is really strong.

After receiving Wei Wu's affirmative answer, Doctor Xu spoke again:

"Could Lord Changle please explain the techniques and skills involved in this in detail?"

"It's impossible."

After giving an affirmative answer, Wei Wu continued:

"Let me start with salicylic acid! Willow tree twigs and bark contain a substance called salicylic acid."

"The simplest way is to boil it in water, then filter it to get a salicylic acid solution, which has analgesic and anti-inflammatory effects."

As soon as Wei Wu finished speaking, Doctor Xu immediately nodded and took over the conversation.

"Yes, according to the Shennong Herbal Classic, the roots, bark, branches, and leaves of willow can all be used as medicine. They have the effects of removing phlegm, improving eyesight, clearing away heat and detoxifying!"

After saying that, Doctor Xu looked at Wei Wu again and asked.

"So, can allicin also be extracted by boiling garlic in water?"

"No."

Wei Wu shook his head in denial, then began to explain.

“Fresh garlic does not contain allicin. It needs to be crushed and left to stand for an incense stick of time before adding water and placing it in a distillation container.”

"Doctor Xu should know something about winemaking! That's right, it's the same method used to extract wine, distillation and condensation."

"But it's important to note that the temperature during distillation can't be too high; it should only be 70% to 75% of boiling water."

"The golden liquid condensed by distillation is allicin. This medicine is best taken internally but can also be applied externally."

Having said that, Wei Wu was about to continue talking about penicillin, but suddenly thought of two very important issues.

"By the way, allicin doesn't last long. If it's stored at room temperature for more than two hours, its effectiveness will disappear."

"However, it can be preserved for a long time in a cold but not frozen environment, but I don't know the exact time."

"By the way, the dosage of allicin needs to be precise. Take it three times a day, and the amount each time should not exceed one centimeter."

(In the Ming Dynasty, weights below one liang were measured in decimal form: one liang was equal to ten qian, one qian was equal to ten qian, and one fen was equal to ten li. One liang = 37.3 grams.)

When the imperial doctors heard the amount Wei Wu mentioned, their scalps went numb. Such a small amount would be difficult to control.

But at this moment, Doctor Xu's words woke them up.

"The dosage is simple. When taking the medicine, just dip your chopsticks in a drop of water, and that should be about the right amount."

After saying that, Doctor Xu looked at Wei Wu again. Although he didn't say anything, Wei Wu understood that he was waiting for the follow-up.

"The production of penicillin is more complicated. It mainly involves extracting mold from moldy food. It has to be Penicillium."

"Then make a pot of beef broth, add the tendons without seasoning, wait for it to cool and solidify into aspic, and then divide it into ceramic bowls."

"And then we use a steamed stick to get some microbial flora from the roof of your mouth and put it on top of the aspic."

"Then collect Penicillium mold from fruit and food, place it on the aspic, and let it sit for about seven days."

Wei Wu paused for a moment here, also to make it easier for the imperial doctors to record it.

When he felt it was almost time, he continued:

"Aspic is a nutrient for cultivating microorganisms. You can also mix rice juice with yam juice."

"Then you need to prepare the filter material. Put hardwood or fruit shells into a metal container with air holes and dry burn it over an open flame."

"When the smoke stops, you get charcoal, which is called activated carbon. Grind it and dry it in the air, and you can use it for filtering."

After another pause of about ten seconds, Wei Wu continued:

"Take some cotton and a clay pot. Use the cotton to filter the culture solution once, then add three times the amount of vegetable oil to the pot."

"Stir until three layers of liquid appear in the jar. Discard the top two layers and keep only the bottom layer of water."

"Use the activated carbon powder you've prepared and stir it, then add a small amount of distilled water, then add acidic water and then alkaline water."

"Acidic water can be made by mixing it with vinegar. You can verify the proportions yourself. As for alkaline water, you can make it by boiling seaweed juice."

"Similarly, the dosage of this medicine is limited, about half a penny is enough. Oh, and all the utensils used must be boiled in water for the time it takes to burn an incense stick."

Finally, after explaining the preparation methods of the three medicines, Wei Wu's throat was almost dry.

Fortunately, he likes time-travel novels and follows a blogger who specializes in these things.

Otherwise, he really wouldn't be able to say so much.

However, just when Wei Wu thought everything was settled and he could ask Doctor Xu for medicine.

The imperial doctors who had just taken notes came over again with papers in their hands.

This time, they were even more detailed than before, not missing any small details.

He dragged Wei Wu to chat for more than an hour, and he was really squeezed out of everything.

After finally getting rid of all these people, Wei Wu finally took the time to pull Doctor Xu aside.

"Old Xu, I've said everything I need to say. The medicine you promised to get for me should be ready by now!"
