Imperial physician Liu Jin was assigned to the military medical camp. The person in charge of receiving him was Tian Bu, the chief officer of the military medical camp. The two met in the camp. After some pleasantries, Tian Bu invited Liu to come into the tent and sit down. Tian Bu

Bu said with some embarrassment, "According to military practice, when entering the military medical camp, you have to pass a medical examination. Please understand." After saying this, he bowed his hand to Liu Jin.

Liu Jin smiled, "That's how it should be."

Afterwards, Tian Bu seriously asked some common sense questions about pharmacology and medical science, and Liu Jin answered fluently. This level was considered passed.

Tian Bu invited Liu Jin to come with him to familiarize himself with the affairs of the camp, and Liu Jin readily agreed.

After leaving the camp, not far away, there were several people in white clothes who were busy around something that looked like an urn but not an urn, but not a pot.

This group of people behaved strangely and dressed strangely. It was not a funeral, so they were all dressed in white, which was a bit strange.

Liu Jin asked curiously.

Tian Bu replied, "This is a military regulation."

"The military advisor has issued regulations requiring military medical officers and other officers to keep their clothes clean at all times and free of any dirt, as they can hide dirt and easily spread diseases.

White clothes cannot withstand dirt, and the slightest contamination will make them stand out, so wear white clothes.”

That's it, Liu Jin nodded.

The two of them walked over together, and when they got close, several busy doctors in white nodded to Tian Bu and said hello, and then continued their work.

Surrounded by doctors in white clothes, there was a huge urn with a lid and a nose. Next to the nose of the urn was a blowpipe. A doctor was squeezing and pressing the urn. Liu Jin saw that the urn was blowing.

The heat blown out of the ladle was blown into a large basin. Liu Jin came closer and took a look. The big basin contained some water that looked like water, was slightly turbid and had some color. He didn't know what it was.

Seeing that Liu Jin was surprised, Tian Bu pointed at the set of tools and asked Liu Jin, "Brother Jin, does he know how to boil medicine?"

Liu Jin asked, "How come you don't know? You can't boil medicine, how can you practice medicine?"

"Yes." Tian Bu nodded. He looked at Liu Jin and asked, "How does Brother Jin prepare the medicine?"

Liu Jin was quite puzzled. He looked at Tian Bu in surprise and replied, "Isn't it just a pound of medicine put in three bowls of water and boiled into one bowl?"

"That's it." Tian Bu nodded and said solemnly, "There is something very wrong with this method of brewing medicine.

I wonder if Brother Jin has ever boiled chicken eggs? Chicken eggs can hatch into chicks if they are not boiled, but if they are heated and boiled, the fetus will be cooked to death.

The same goes for medicine."

"Nine out of ten medicinal properties cannot be boiled. After boiling, nine out of ten medicinal properties will be resolved. Ordinary methods of boiling and decoction will destroy nine out of ten medicinal properties and only one or two of them can be used."

"Therefore, the military advisor taught us the method of quenching the medicine with warm water. The method is to boil the medicine in warm water without boiling the water or overheating the water and damaging the medicine.

In the past, we used a large vat to hold the medicine and a pile of firewood. We tested the water temperature from time to time, brought water to scald our hands, and immediately removed the firewood. When the water cooled slightly, we immediately moved the fire.

On the one hand, this method is cumbersome, and on the other hand, it is better to have more water in the jar. The water will heat up slowly and the cold and heat can be controlled. When the medicine in the jar is boiled until only the bottom of the jar is left, there will be very little water in the jar.

When it gets hot, the medicine will boil, and if it boils, the medicine will be destroyed, making it difficult to control it at this time."

"Therefore, there is also the hot wind method."

Speaking of the hot air method, Tian Bu thought for a long time before he finally understood the principle of the hot air method. He asked Liu Jin, "I wonder if the imperial doctor has ever noticed that the water on the ground dries quickly when there is wind, and dries slowly when there is no wind.

It dries hard when it’s hot, but dries slowly when it’s cold.”

When Liu Jin heard this, he thought, this is what happened, but what does it have to do with boiling medicine?

Later, Tian Bu explained that the hot wind method was like this. The medicine was boiled with fire, and the concoction boiled easily. However, on weekdays, the water marks on the ground were dried by the wind and sun, and there was no boiling water.

Therefore, the hot air blowing method is like this, blowing hot air onto the surface of the medicinal juice, making it pass over the medicinal juice like hot air. In this way, a large pot of medicinal juice will be cool from beginning to end and will not be scalded.

If the water is not scalding, the essence of the medicine will not be damaged. Only when the essence of the medicine is very high can it be quenched to 10%.

Tian Bu also said that in the past, hot air used an iron pipe connected to a bellows. The iron pipe was burned with fire. The iron pipe was heated. Once the air in the bellows passed through the iron pipe, it became hot air.

Later, I thought firewood was useless, so I used hot air, which was much simpler.

Liu Jin was very curious about this unheard of method of obtaining medicine. He went to the big pot of medicine and took a look. More than one-third of the medicine in the pot had been broken off. Liu Jin asked curiously

Tian Bu, "What kind of medicinal materials are boiled in this pot?"

[To be honest, I have been using the Huanyuan app recently to read and catch up on updates. It allows me to switch between sources and read aloud with many sounds. .huanyuanapp is available for Android and Apple.]

Tian Bu didn't know what he was suffering from. He asked several military doctors, and the military doctors replied that it was raw land.

Liu Jin didn't believe it when he heard it. The juice from the raw rehmannia has a color. How could it be so clear and water-like?

When Liu Jin expressed his doubts, Tian Bu smiled and asked Liu Jin to try it himself.

Liu Jin was curious, so he bent down and dipped his fingers into the concoction, then put it in his mouth. The strong and sweet herbal taste filled his entire mouth.

As the imperial physician of the imperial court, Liu Jin was very skilled. He could tell right away that this was really the concoction of raw earth. When he tasted it, Liu Jin had an extremely strange feeling. He had never tasted it in his life.

Such a strong, fresh and pure raw ground taste is as if it is concentrated from hundreds of kilograms of raw ground.

When Liu Jin was asked to give an analogy, Liu Jin remembered the Julu wine he drank during the banquet. The same goes for Julu wine. The wine was extremely strong and the taste was extremely pure. It was pure except for the smell of wine and a few other odors.

All gone.

When Liu Jinza touched his teeth and expressed his feelings, Tian Bu burst out laughing.

Liu Jin guessed it completely. It was really a concoction extracted from hundreds of kilograms of raw rehmannia. All other impurities were eliminated and only the unique medicinal substances of the raw rehmannia were extracted. This only had the most basic taste of the raw rehmannia without any other complicated ingredients.

smell.

The method of quenching medicine was a secret technology of the rebel army. Since Liu Jin was not an outsider, Tian Bu told him all about the method of quenching medicine.

This chapter is not over yet, please click on the next page to continue reading! Tian Buta talked about a truth, and the imperial doctor Liu Jin seemed to understand it. Anyway, he roughly understood that all medicinal substances should be mixed with white vinegar or not.

Wine, oil, water, lime water, either add spirits and nothing else, or add lime water. In this way, the medicinal substances can be quenched out.

Tian Buyan said that it is not difficult to quench the medicine, but it is difficult to know whether to add vinegar, wine or water to find out what is useful in the medicine. During this time, all the doctors in the military medical camp have tried hundreds and thousands of times, and they have spent a lot of time.

How many medicinal materials, wine and vinegar were taken, and after so long, only nine types of medicines were detected, and the raw land in front of me was one of the nine.

Liu Jin asked, what are the nine essential medicines?

"The first one is heat-clearing powder. This medicine is taken from the bark of willow branches. About ten pounds of bark can be boiled into three or two spoons of coarse powder.

This medicine is very effective, it can cure fever and wind-cold, and it also has analgesic effect."

"The second kind, licorice pill."

"The third one is Ginkgo Pill."

"The fourth kind of Jiang Dan..."

Except for the first medicine, the willow bark was extracted by Li Mengxi and others, the rest were tried by military doctors themselves. This can be seen from the naming method. Li Mengxi named the medicine after a certain person.

I'm a fan, but the names given by military doctors are all about this pill or that pill.

Military doctors must have some pursuit of refining elixirs to become immortals.

As the chief officer of the medical camp, Tian Bu took various medicines with him. He untied a small gourd from his waist, pulled out the stopper of the gourd, and poured out a handful of round pills the size of white fruits.

The pills were rolled and shaped, and they were wrapped in a layer of tissue paper with a name written on the paper.

Tian Bu picked them up and gave one of each type of elixir to Imperial Physician Liu Jin.

Traditional Chinese medicine practitioners have a unified method for testing medicines. Whether it is Tian Bu from Julu or Liu Jin from Luoyang, these doctors from all over the world use the same method of testing medicines as Shen Nong. They all eat the medicines themselves to test the properties of the medicines.

Liu Jin picked at the small pills in Ke's hand and chose [Jiang Dan] to give it a try.

I tore open the paper covering outside the elixir, and inside was a pale yellow round pill. I picked up the pill and sniffed it, smelling of the strong spicy smell of old ginger.

Stick out your tongue and lick it, it will feel hot on the tip of your tongue.

Tian Bu smiled and said, "Do you dare to give it a try?"

"Why don't you dare?" Liu Jin replied proudly. Ginger wouldn't kill anyone. Liu Jin put the elixir in his mouth, his throat moved, and he swallowed the medicine with a gulp.

Tian Bu grinned.

Jiang Dan is not fun. Although ginger cannot kill anyone, one ginger pill is equivalent to several kilograms of ginger. When we were testing the medicine...

Tian Bu also invited Liu to visit other places in the camp, and Liu Jin did everything he could.

While wandering around, Tian Bu carefully introduced everything in the camp to Liu Jin.

"We have a wounded barracks here, and there is another medical camp somewhere else.

The wounded soldiers' camp is separated from the ordinary medical clinic. This is because the wounded soldiers have weak Qi and blood and are susceptible to diseases. There are many people in the city and there are many patients coming and going for medical treatment, so they need to be separated."

"Our wounded barracks is located in a remote place, and no outsiders move around frequently on weekdays."

"...The camp is cleaned every day, white ash is spread every three days, and the ground is burned every ten days. This is the end of the epidemic."

"...Horses and poultry are not allowed in the camp. Only boiled water can be used in the camp, not raw water."

"...the cloth used to wrap up the wounds of wounded soldiers cannot be used twice, and will be destroyed after use."

As they were talking, the two of them came across a slaughter scene. It was wrong to call it a slaughter scene, it was a bit weird.

The military doctors tied up a sheep and held it in place. The sheep was also strange. There was a bald spot here and there on the sheep's body, and there were centipede-like marks on the bald areas.

Liu Jin was very surprised. As he was watching, a military doctor took a knife and stabbed the lamb's ribs, causing the sheep to bleat in pain.

If he wanted to kill a sheep, cut his neck, or use a big knife, Liu Jin's heart was pounding when he saw the actions of the military doctors.

Then, something even weirder happened. After making a cut on the lamb's ribs, the military doctors were hurriedly holding basins, scissors, needles and threads, and cloths to wipe the blood.
