Chapter 124 Controlled and comparative experiments
In order to win over the heartless Li Xi, he must of course protect his own face.
Gu Jingzhi never imagined that one day he would have to use his looks to win over a woman.
……
Doctor Wu took a piece of paper and pushed it towards Li Xi. "This is what I have earned during this period of time. Come and take a look, young friend."
Li Xi put down the medicine bag and picked up the piece of paper with the names of medicinal materials written on it. After reading the contents clearly, Li Xi raised her eyebrows and looked at Doctor Wu. Yes, the prescription written on this paper is almost the same as the one she used when making the drug.
The difference is that Dr. Wu also used other herbs as a substitute. Although the efficacy may be slightly worse, it is not much worse.
Li Xi said with admiration: "Amazing, I admire you."
"No, no." Doctor Wu stroked his long beard, looking slightly complacent.
“Doctor Wu, there is no need to be too modest. I know the medicine I made myself. The preparation of this drug is different from the previous hemostatic and anti-inflammatory drugs. Not only are there more medicinal materials used, but there are even more unconventional ones.
It is really amazing that Dr. Wu can come up with so many medicinal ingredients based on just a small amount of finished product."
There were no component analyzers in ancient times. It is truly admirable that Dr. Wu could achieve this level with just that little bit of powder.
Under the same conditions, Li Xi couldn't guarantee that he could achieve the same level as him.
"Is there a finished product?" Li Xi asked.
"Yes." Doctor Wu took out a porcelain bottle from the drawer. "There are indeed many rare herbs. Fortunately, I still have some in stock, but not much. I only made a small bottle like this."
Li Xi took the porcelain bottle, opened it and looked inside. The color was a little yellower than the one she made.
As for the effect? Li Xi looked at the two doses of the drug, and asked the most common question in the laboratory, "Have you done a control experiment?"
"Controlled trial?" Doctor Wu looked at Li Xi blankly. What is this?
Seeing the confusion on Doctor Wu's face, Li Xi finally realized that this was not modern times, nor was it a laboratory.
"Uh." Li Xi was stunned for a moment and explained, "A controlled experiment is an experiment conducted on the research subject with the same conditions except for the condition being different, to explore the effect of a certain condition on the research subject."
"I have tested these two drugs on two rabbits before. The one you used is more effective." Doctor Wu looked curious. "I have always called this a drug test. I didn't expect there is such a term."
"It all means the same thing."
"But yours is more interesting. A control experiment?" Doctor Wu looked at Li Xi inquiringly, "Do you have any other experiments?"
Li Xi: ...So that’s how the topic deviates?
"Yes, there is, but shouldn't we take care of it first..." Li Xi glanced at the medicine bag on the table.
Doctor Wu followed her gaze and said, "It's okay. The medicine is there anyway. It won't go away. We can talk about it later."
He already knew the effects of the two drugs, although there were still some things he didn't understand, but it was obvious that the new knowledge from Li Xi attracted him more.
"There is also a comparative experiment. A comparative experiment is to set up two or more experimental groups and explore the relationship between the factors and the experimental objects through comparative analysis of the results." Seeing that he insisted, Li Xi said another one.
This time Doctor Wu was stunned and looked at Li Xi with a bewildered face. What, what did this mean? He didn't understand a word of it.
Seeing Dr. Wu's face full of question marks, Li Xi was not surprised. He had done control experiments before so he could accept it so quickly.
After thinking for a while, he explained, "For example, observe the use of the same prescription on people of different ages."
"Now I know what you mean." Doctor Wu understood. "So that's what you mean."
He had done this kind of experiment before, but he didn't have a specific name like Li Xi's. It's better this way, so people will know what it means once it is mentioned.
Li Xi: "Then continue?"
"According to the drug test, uh, according to the control experiment, the rabbits that were drugged by me took three breaths longer to completely pass out than the rabbits that were drugged by you, and woke up half a quarter of an hour earlier."
Li Xi nodded. "It's already pretty good to have achieved this with just that little bit of powder. It's only three breaths short, or half a quarter of an hour longer."
In fact, for others this is not a problem at all. After all, this is several times better than the existing Ma Fei San. But who can blame Dr. Wu for being a doctor who strives for perfection?
"For those of us who study medicine, a slight mistake can lead to a huge error," said Doctor Wu seriously.
Dr. Wu's words shocked Li Xi's heart, and she suddenly remembered her university motto: Rigorous, innovative, extensive, and dedicated.
rigorous.
The first time she heard this word was from her grandfather. Her grandfather told her that the most important thing for a doctor is to be rigorous and careful. In medicine, one is one and two is two. There can be no ambiguity.
Although she had never realized it, perhaps because of her identity as a time traveler, she subconsciously looked down on others without even realizing it. She subconsciously felt that her knowledge was far beyond that of this era, and unconsciously looked down on others with an air of being out of the loop.
"Doctor Wu is right. A slight mistake can lead to a huge error. You are right and I am wrong."
Li Xi took the paper on the table, placed it in front of herself, ground ink, dipped the pen, and wrote the recipe for the drug on the paper. After writing, she picked up the recipe and shook it gently to speed up the solidification of the ink.
"This is the recipe for the drug." Seeing that the ink was slightly dry, she handed the recipe to Doctor Wu.
During this period, Doctor Wu had been looking at Li Xi silently, with satisfaction in his eyes, as if he was looking at a satisfied and qualified junior.
Seeing her handing over the prescription, Doctor Wu took it and read it carefully. He couldn't help but read it again from the beginning. The more he read, the brighter his eyes became. "Great, great!"
"Datura flower, Achyranthes bidentata, jasmine root, stir-fried Arisaema, Angelica dahurica, raw Aconitum, raw Aconitum?" Doctor Wu suddenly looked up at Li Xi, "How did you come up with the idea of using raw Aconitum instead of processed Aconitum?"
The toxicity of raw Aconitum is stronger than that of processed Aconitum, so when making Ma Fei San, they usually use processed Aconitum.
The toxicity of raw Aconitum after processing will be greatly reduced, making the prepared Ma Fei San safer.
Li Xi: This was not her idea at all. She just made a slight change to the Ma Fei San that has been passed down for five thousand years. It is not original at all. She just leaned on the shoulders of giants.
"Although the toxicity of raw aconite is stronger than that of processed aconite, it is also far more effective than processed aconite in some aspects, such as analgesia."
Doctor Wu suddenly realized: "So that's it, so that's it."
