"Teacher Yun, judging from the pulse and symptoms, it seems that there is a deficiency of both water and fire in the liver and kidneys."
Wang Xuemeng said to Yun Heng.
"Yeah, I think so too."
He Yongfei nodded.
"Why does deficiency of both water and fire in the liver and kidneys lead to blindness?"
Yun Heng asked with a smile.
"Teacher Yun, I don't know."
Wang Xuemeng stuck out her tongue: "Did I make a wrong judgment?"
"Judging from the pulse and symptoms, the patient is indeed suffering from deficiency of both water and fire in the liver and kidneys."
Yun Heng nodded and explained, "The Neijing says that a person's two eyes are like the sun and the moon. The cloud eye receives blood and can see. Those who are blind are like the sun's fire essence is insufficient, and the moon's water essence is weak..."
"Teacher Yun, I understand."
Wang Xuemeng hurriedly said, "The liver is the organ that stores blood, and it opens to the eyes. The reason the eyes glow and can see is because of the pupil. The pupil belongs to the kidney, and the kidney stores water and fire. Liver deficiency means blood deficiency, and kidney deficiency means both water and fire deficiency. Therefore, both blood and essence, water and fire are deficient, so they cannot nourish the eyes."
"right."
Yun Heng smiled and nodded. "Water can reflect things, and fire can emit light. Therefore, ancient sages believed that those who are nearsighted but not farsighted were without fire, and those who can see farsighted but not nearsighted were without water. Those who cannot see at all are a sign of both water and fire deficiency."
"Didn't you understand?"
Yun Heng asked He Yongfei.
"Teacher Yun, I really don't understand what you heard."
He Yongfei nodded: "I know the concepts of water and fire, but I always feel that it is inappropriate to use such concepts to describe the eyes, so I can't figure it out."
"Let's go, let's talk outside."
As he spoke, Yun Heng walked out of the ward, and the others hurriedly followed.
In fact, it was not just He Yongfei and Wang Xuemeng, Han Xiaojun also felt quite confused after hearing it.
The reason why many people now say that traditional Chinese medicine is unscientific is actually because they don’t understand it and feel that some of its explanations and theories are messy.
Most of what Yun Heng said just now came from the "Inner Canon of Medicine", but He Yongfei still didn't quite understand this explanation. It's not that He Yongfei had never read the "Inner Canon of Medicine". Even if he had, most people would not understand some of its concepts.
Another point is that some ancient classics, such as "The Analects of Confucius" and "The Yellow Emperor's Classic of Internal Medicine", do not have punctuation marks. Chinese characters are profound and extensive. The same characters have many interpretations even today, not to mention classical Chinese without punctuation. Different sentence breaks will lead to completely different meanings.
Many people know that the Analects has been studied by many people in later generations. Because the Analects has spawned many schools of thought, many literary masters in later generations have interpreted the Analects in their own way.
The same is true for traditional Chinese medicine. Later generations stand on the shoulders of their predecessors to conduct research. One person understands it this way, another person understands it that way. As long as it makes sense and conforms to the basic concepts of traditional Chinese medicine, any understanding is acceptable. This is also the fundamental reason why many medical schools have emerged in traditional Chinese medicine.
"That's the doctor's intention!"
As Yun Heng walked, he explained to Wang Xuemeng and He Yongfei, "Do you know what this means?"
"Teacher Yun, 'Medicine is intention' is a reflection of objective things and a summary of the mental activities revealed by these things. To be more precise, the 'intention' in 'Medicine is intention' is actually closely related to the mental activities of the heart, will, ambition, thought, consideration, and wisdom."
"Um."
Yun Heng nodded. "Xiao Meng is right. The idea of medicine is also the earliest theory of 'treating specific cases in specific ways'."
The meaning of "medicine is intention" was clearly indicated as early as in the "Inner Canon of Medicine". "Lingshu: Benshen" says: "So what governs things is called the heart, what the heart remembers is called intention, what the intention stores is called will, what changes due to will is called thinking, what aspires to be far away due to thinking is called worry, and what is handled due to worry is called wisdom."
"The phrase 'medicine is about intention' is actually a serious warning to those who do not study medical principles, do not pay attention to practicality, rely on subjective imagination, and treat diseases at will."
Yun Heng glanced at He Yongfei and continued, "Don't take many of the theories in Chinese medicine literally. As I just said, studying people is like the sun and the moon. Are the eyes really the sun and the moon?"
"Of course not."
Wang Xuemeng hurriedly said, "The ancients didn't have a sufficient understanding of things. They didn't understand the true nature of the moon and the sun. So they believed that the sun contained solar fire and the moon contained lunar essence. If the sun's fire was insufficient, the sun would be dim and not hot. If the moon's essence was insufficient, the moon would be dim and not large."
"right!"
Yun Heng nodded and said, "This is the truth. In other words, this truth and cognition are consistent with the relationship between human eyes and the sun and moon."
Yun Heng paused and continued, "Many people dislike myths. In fact, myths are all made up by humans. Myths and legends are not without basis. These bases are actually in line with certain laws and cognitions at the time. We must judge carefully and seek the relationship between man and nature, rather than simply apply them."
"So, in other words, it's not that the eyes are like the sun and the moon, but rather that the sun and the moon are like the eyes?"
He Yongfei was not stupid and understood it quickly.
"Yes, the same meaning, but the meaning is different when it is reversed."
Yun Heng smiled and nodded.
