Chapter 440: Explaining the Origin
"It's not wrong for you to understand that." Su Yayan affirmed his answer, "A large part of you are students of the Department of Pharmacy, and you should know that a large part of the current medicines are composed of chemical components and biological preparations. . And Chinese medicine, as this classmate said, many are plants, but not all are plants."
"Just like bezoar, it is a stone in the gallbladder, bile duct or hepatic duct of cattle or buffalo, but it has the functions of clearing the heart, resolving phlegm, promoting gallbladder, and calming convulsions. Tongue sores, carbuncles, boils and other symptoms also have certain effects."
As soon as Su Yayan said these words, there was another uproar.
"The stones in the cow's stomach are actually Chinese medicinal materials?"
"Shouldn't the stone be condensed from the dirt in the stomach? How can I eat it? Isn't it poisonous?"
The people below were talking about it, but Su Yayan took a deep breath and said, as if she had expected it long ago: "This is the reason why we want to learn this subject now, if I hadn't told you that bezoar is actually an important one, you would have thought that Can the stones in the belly of a cow be used to treat diseases?"
The crowd fell silent for a moment.
"In ancient times, Shennong tasted all kinds of herbs and left the "Shen Nong's Medicine Classic", and later Li Shizhen worked hard to compile the "Compendium of Materia Medica" and spread it to the world. The purpose is to let the world understand the value of these Chinese herbal medicines, so that they can be used to cure diseases and save people. It's a pity that most of these precious books and many precious Chinese medicinal materials were lost during the two migrations of human beings."
"I have a problem." As soon as Su Yayan finished speaking, someone asked another question, "Teacher, ah no, Miss Su, since most of these things are lost, how do you know about them?"
Su Yayan had already expected that someone would ask this question, even if it wasn't the students present today, it would be someone else.
"Because my family happens to be one of the small parts that have been preserved. Just like recipes, some have been preserved in the rush of migration, but a large part is still lost. For this reason, the research institute will develop a nutrient solution, which is convenient for The masses are also able to fill their stomachs at the same time.”
The planet they live in now is still somewhat different from the ancient earth. Just like the animals in this place, including seafood, are larger than those on the ancient earth, and even if some vegetables can be grown, they are smaller than those on the ancient earth. , which is why natural ingredients, especially vegetable ingredients, are extraordinarily expensive.
When humans first set foot on this land, they were unable to determine whether the plants on this planet, or even the plant seeds they brought, would mutate and be poisonous when planted on this land.
Coupled with the loss of recipes, the research institute simply came up with a nutrient solution that can extract animal and plant nutrients.
It's just that this thing is like compressed biscuits. It concentrates and extracts all the nutrients of the food, which can satisfy the stomach and satisfy the various nutrients needed for human survival, but sacrifice the most important taste of the food.
Even knowing that this thing is easy to drink and cheap, many people still want to eat fragrant meals.
"You mean that your family has books related to it? What about those Chinese medicine seeds? Are they also left by your ancestors?"
As soon as this question was asked, many people pricked up their ears. Obviously, it was not only the one who asked the question who was curious, but many people who were curious, but they were just too embarrassed to ask before.
