Xiao Zimo carefully observed the wild water chestnut.
“Mom, this wild water chestnut looks very similar to a weed. How can we tell them apart?”
Bei Yutang pulled out a weed from the side and put the wild water chestnut and the weed together. From their appearance, it was almost impossible to tell them apart.
She put the wild water chestnut to his nose and asked, “What’s the smell?”
Xiao Zimo sniffed and replied seriously, “A faint grass fragrance, and… there is also a fragrance like orchids.”
After saying that, he tilted his head back and looked at her.
Bei Yutang did not answer whether he was right or not, but she put the wild grass to his nose, “Smell this again.”
Xiao Zimo also sniffed it carefully and replied cautiously, “It also has the fragrance of grass, but it has a smell of earth, not the fragrance of orchids. Mom, am I right?”
Bei Yutang nodded.
“Yes. In addition to the grass fragrance of the real wild water chestnut, it also has a subtle orchid fragrance, but this fragrance is very faint. If you don’t smell it carefully, you can’t tell it apart. Nowadays, many wild water chestnuts in many medicine shops are made of this kind of wild grass, which has no medicinal effect at all.”
Xiao Zimo thought that when Bei Yutang found the wild water chestnut before, she didn’t smell it at all, but she saw it from a distance and picked it accurately.
“Mother, is there any other way to distinguish it?” Xiao Zimo asked.
Bei Yutang smiled and said, “Smart. After the wild water chestnut is dried, the orchid-like fragrance will dissipate, resulting in many weeds being used as wild water chestnuts on the market. In fact, in addition to smelling its own smell, there is another way to distinguish it.”
This time, Bei Yutang put the two things in front of him and asked him to observe carefully.
Sometimes, what you discover yourself is often more memorable than what you hear from others.
Xiao Zimo carefully compared the two plants and finally found the difference between the two.
“Mom, I found it. The leaves of weeds are rectangular, and the leaves of wild water chestnuts are slightly oval.” Xiao Zimo said excitedly.
“Yes, you are right. But if you don’t look carefully, it is difficult to distinguish between the two. But once you know the difference between the two, you will feel completely different when you look at the two things again.”
This feeling is like being used to seeing and using real things, and once you touch a fake, you will recognize it at a glance.
Xiao Zimo nodded. What his mother said was absolutely right.
Now he was looking at the pile of weeds. As expected, he could tell at a glance that there were a few wild water chestnuts among the weeds.
Every time Bei Yutang saw something, she would teach him step by step.
After Xiao Zimo saw that those seemingly harmless herbs would become highly poisonous when mixed with another herb, his interest was aroused.
Before, he agreed to learn these things to reassure his mother and purely listen to her, but now his interest was aroused by this magical change. The charm of herbs and poisons aroused his strong desire to explore.
Bei Yutang naturally noticed the changes in the little guy. She was very happy to see his changes.
It is said that interest is the best teacher.
As long as he is interested and has the desire to explore and seek knowledge, he will make faster progress than before.
In the next few days, Bei Yutang took Xiao Zimo up the mountain every day.
The little guy learned very quickly. Just like his talent for learning, he memorized all the pharmacological theories after just one reading.
