"You're not wrong to understand that." Su Yayan gave some affirmation to his answer, "A large number of you are students in the Department of Pharmacy, and you should know that a large part of the current medicine is composed of chemical components and biological agents. And traditional Chinese medicine, as this classmate said, many are plants, but not all of them are plants. ”

"For example, the bezoar, it is a stone in the gallbladder, bile duct or liver duct of a cow or buffalo, but it has the effect of clearing the heart, dissolving phlegm, relieving choleretic, and suppressing convulsions, and has a certain effect on children's convulsions, epilepsy, tooth scabies, throat swelling, mouth and tongue sores, carbuncles, boils and other pathologies."

As soon as Su Yayan's words came out, there was an uproar below.

"The stones in the cow's belly turned out to be Chinese medicinal materials?"

"Shouldn't stones be formed by the dirt in your stomach? How do you eat this? Won't it be poisoned? ”

There was a lot of discussion among the people below, but Su Yayan took a deep breath as if he had expected it: "This is the reason why we want to learn this subject now, if I didn't tell you that the bezoar is actually an important one, would you think that the stones in the cow's stomach can also be used to treat diseases?" ”

The crowd was silent for a moment.

"In ancient times, Shennong tasted a hundred herbs and left the "Shennong's Medicine Sutra", and then Li Shizhen worked tirelessly to compile the "Compendium of Materia Medica" and circulated it in the world. In order to let the world understand the value of these Chinese herbal medicines, so that they can be used to treat diseases and save people. It's a pity that most of these precious books, along with many precious Chinese medicinal materials, were lost during the two migrations of human beings. ”

"I have a problem." As soon as Su Yayan's voice fell, someone asked again, "Teacher, ah no, Miss Su, since most of these things are lost, how do you know about them?" ”

Su Yayan had also expected that someone would ask this question, even if it wasn't the students who were here today, it would be someone else.

"Because my house happens to be one of those small parts that have been preserved. Just like recipes, some of them have survived the migration, but a large part of them have been lost. For this reason, the research institute will develop a nutrient solution that is convenient for the public and can also fill everyone's stomach. ”

The planet they live on now is still different from the ancient earth after all, just like the animals in this place, including seafood, are larger than the ancient earth, and even if some vegetables can be grown, they are smaller than those on the ancient earth, which is also the reason why natural ingredients, especially vegetable ingredients, are extremely expensive.

When humans first set foot on this land, they were not sure whether the plants on this planet, or even the plant seeds they brought to this land, would mutate and be poisonous.

Coupled with the loss of the recipe, the institute simply made a nutrient solution that could extract animal and plant nutrition.

It's just that this thing is like a compressed biscuit, which concentrates and extracts all the nutrients of the food, which can fill the stomach and meet the various nutrients needed for human survival, but sacrifices the most important taste of the food.

Even though they know that it is easy and cheap to drink, many people still prefer to eat fragrant meals.

"You mean you have a book about it at home? What about those Chinese medicine seeds? Is it also a legacy of your ancestors? ”

As soon as this question came out, many people pricked up their ears, obviously not only the one who asked the question was curious, but many people were curious, but they were embarrassed to ask before.
