Chapter 750: There are more drug combinations than billions of stars(1/2)
February 20th was the day after Li Mengxi handed the willow extract to Tian Bu, and Tian Bu took the powder to test the medicine.
On this day, Tian Bu went to check on the conditions of the patients early in the morning.
In the first tent, there were ten people in the first tent. These ten people took the water extract of willow tree yesterday. As of this morning, half a day has passed.
Tian Bu arrived and saw the patients sitting on the beds in the tent chatting. He walked into the tent and asked politely, "How are you? Do you feel better today?"
The patients returned, "I feel much lighter."
This question and answer are very common.
When Tian Bu used to practice medicine in the countryside, people came to see the doctor and prescribed medicine. Regardless of whether the medicine was useful or not, the people would choose the best one and say it was better. Tian Bu did not take the patients' answers seriously.
, just think that the patients are casually agreeing.
Tian Bu called the patients together and began to check their conditions.
Tian Bu sat on the bedside, put the patient's hand on his knee, and clasped the patient's wrist with his fingers. He frowned slightly, lowered his eyebrows attentively, and concentrated on feeling the pulse.
After checking the pulse for a while, Tian Bu found that the patient's pulse was peaceful and did not look like he was suffering from an illness.
Raising his head, Tian Bu glanced at the patient in surprise and looked at the patient in front of him carefully. Tian Bu saw that the patient's eyes were clear, his face was normal, and he had no cough or runny nose.
It's obvious that this patient is getting better.
The first patient recovered from the cold.
Tian Bu has sufficient experience in practicing medicine. The disease of wind-cold can be serious or minor. Some people are infected with wind-cold and die in the blink of an eye. Some people are infected with wind-cold and can be cured by sleeping under a quilt overnight.
At this point, Tian Bu only thought that the patient was strong and had recovered from his condition.
After that, Tian Bu continued to investigate, and after checking the pulses of five people in succession, Tian Bu found that all five people had recovered.
Tian Bu clearly remembered that just yesterday, after placing the patients, he took the pulses of the patients one by one. He clearly remembered that among the dozens of patients, every one of them had wind-cold pulses that were floating and tight.
After only half a day, I looked again and found that ten people were half better.
At this point, Tian Bu was surprised. He had a vague feeling that it might be due to the effect of the medicine.
There were five people left. Tian Bu hurriedly checked the pulses of the remaining five people. After checking the ten patients, seven of them had recovered. The remaining three were not in good condition and their condition had greatly improved.
In Tian Bu's past medical experience, when he contracted a cold, he could not recover quickly even with medication. The only possibility was that the medicine given by the military advisor was too strong.
Tian Bu couldn't help but ask a group of patients how they felt after taking the medicine yesterday.
The patients couldn't explain why, they just said they felt much better after taking the medicine.
Tian Bu nodded, said goodbye to everyone, and hurried to the next patient settlement site.
When we arrived at the second resettlement site, there were still ten patients in the tent. These ten patients only drank some licorice water yesterday and did not take any medicine.
Tian Bu began to feel the pulse of these patients who drank licorice water. Without waiting for the pulse, Tian Bu also saw that these ten patients had coughs and runny noses, and their condition was worse than yesterday.
After Tian Bu finished examining the second group, he found that among the ten patients, there were still ten patients, and not one of them had recovered.
Tian Bu left in a hurry again and went to the third group.
The third group was ten patients who did not drink medicinal powder, nor drank licorice water, nor drank anything. After investigation, only one of the ten patients was cured. On the other hand, nine of the ten patients were not cured.
.
Tian Bu arrived at the fourth group. In the fourth group, all ten people drank medicinal powder made from willow bark boiled in lime water. Tian Bu did not understand the difference between boiling willow bark in lime water and boiling it in clean water. However, when Tian Bu
After checking the fourth group, he found that five out of ten patients with colds had recovered.
The last group is left, and the last group is three groups of people who took common herbal medicines, a total of thirty people.
Tian Bu went over to check and found that half a day had passed among the thirty patients who had drank the herbal medicine. As a result, only six of the thirty patients had recovered.
Tian Bu did not have the ability to accurately analyze data, but after this verification, Tian Bu also discovered that among the patients who used the medicinal powder given by the military advisor, twelve of the twenty people who used the medicinal powder were cured.
, fully 60% recovered.
And among those who did not take medicine, almost no one recovered.
For people who use ordinary herbal medicine, six out of thirty people are cured, and only 20% are cured.
The contrast was so obvious and the effect of the medicine was so strange that even Tian Bu was shocked.
——
Tian Bu hurried to the city lord's palace to find Li Mengxi. Seeing Li Mengxi, Tian Bu was very excited, "Military advisor! The medicine is useful, it's useful!"
Li Mengxi, who was lying down writing notes, raised his head, glanced at Tian Bu, and extended his hand to invite, "Come on, Tian Bu, come here and explain in detail."
Tian Bu sat down on the opposite side. After sitting down, Tian Bu excitedly told the test results.
Following Tian Bu's narration, Li Mengxi roughly understood it. He frowned slightly and touched his chin to think. (After taking the medicine, in just half a day, the wind and cold were 60% better. This... what is the thing in the willow tree?
The efficacy of the medicine is so damn overbearing!)
The extract of willow bark was so powerful that Li Mengxi was shocked.
Tian Bu expressed his opinion seriously, "Commander, I think it is better to boil willow bark in clean water than boil it in lime water."
Li Mengxi thought for a while, in the clear water group, seven out of ten people were cured, and in the lime water group, five out of ten people were cured.
Judging from the data, there is indeed a difference.
However, it is still uncertain whether this is an individual error or whether the water extract is really different from the lye extract.
There are only ten people in a group, and the data sample is too small. It is possible that none of these ten people will have any effect after taking the medicine, and it is equally possible that all of them will have an effect.
Li Mengxi felt that unless there were a thousand samples for comparison, it would be somewhat convincing. Ten samples would not be convincing enough.
After thinking about it, Li Mengxi looked at Tian Bu and said, "Tian Bu, this is not the water that is useful, this may be an error."
This chapter is not over yet, please click on the next page to continue reading! Tian Bu was confused and didn’t quite understand what the error meant.
Later, Li Mengxi thought that since the willow extract was so useful, he could try to produce more of it. The production method was simple anyway, just break some willow sticks and boil them.
Tian Bu looked at the pensive Li Mengxi, hesitated and hesitated, opened his mouth a few times, and finally couldn't help but said, "Commander, hehe, this...how did you make this medicine?" Tian Bu was very embarrassed.
asked.
Li Mengxi raised his head and looked at Tian Bu who looked embarrassed. He smiled and said, "You want to tell me the prescription? Come on, I'll tell you to write it down carefully."
"The prescription is simple and not difficult.
...In this case, let me teach you how to extract it.
First, what is extraction?
Rather, it is called extraction to sift out the mixed things."
After explaining the concept, Li Mengxi stared at Tian Bu and asked, "Tian Bu, do you know how to boil salt?"
Tian Bu said, "Someone knows."
Li Mengxi then asked, "It's like boiling salt. In the bitter water, there are salt, sand, and water. So how can we remove the sand and water and leave pure salt?"
Tian Bu replied, "Pour the bitter water through a gauze, filter out the sand and soil, put the clear juice in a vat, add fire and simmer it, wait until the water goes away, and what is left is salt."
Li Mengxi nodded, boiling salt is just a common skill, Tian Bu naturally understands it.
Next, Li Mengxi began to teach Tian Bu a versatile method for extracting willow medicinal powder and extracting the active ingredients of various medicines.
Li Mengxi said, "Sifting through gauze and boiling to remove water are just common extraction methods.
I have another special extraction method here. This type of extraction method can be called the dissolution extraction method.
What is dissolution? Some substances are soluble in water but not in vinegar, and some, conversely, are soluble in vinegar but not in water.
Suppose there is an herbal medicine, and there is a substance that cures diseases in the herb. This substance that cures diseases is soluble in vinegar but not in water. Then Tianbu, let me ask you, how do you extract this substance?"
How to "extract" something that can dissolve in vinegar but not in water?
Tian Bu thought about it. After a while, he looked up at Li Mengxi and answered hesitantly, "...but soak this herb in vinegar and boil it?"
Tian Bu's ability to comprehend was still very strong. Li Mengxi smiled, and Tian Bu nodded, "Yes, that's it."
Tian Bu understood the extraction method, but after thinking for a while, Tian Bu couldn't help frowning and asked doubtfully, "But Military Advisor, there are already cures in herbal medicines. Eating herbal medicines can't cure diseases, so why bother?"
Should I bother extracting it?”
Seeing Tian Bu's confused look, Li Mengxi thought for a moment and replied, "This is different.
Your doctors often say that there are three parts of medicines that are poisons. Why is there three parts of medicines that are poisons? Because there are many substances in herbal medicines. In addition to the substances that can cure diseases, there are also many toxins.
Tian Bu, you ask me, since herbs can cure diseases, why bother to extract them? This is the reason.
A single herb has three parts of medicinal value and three parts of poison. Without extraction, the medicine is used directly. The three parts of medicine and the three parts of poison are combined into the body. This not only cures diseases but also damages the body. This is one of them.
Second, dose.
What is dose?
If a drop of snake venom is dropped into a bowl and a person drinks it, he will die immediately.
A drop of snake venom drops into a river, and people drink the river water without any trouble.
Poison is like this, and medicine is like this.
Herbal medicines contain very little medicine. Suppose a few ounces of medicinal substances are needed to treat a disease, and the amount of medicinal substances contained in one herb is only one thousandth of a ounce.
