Listening to Fang Yan's words, the classroom became quite quiet again.

What Fang Yan said is the truth of Chinese medicine now.

In many cases, the reason why patients are reluctant to choose traditional Chinese medicine is that they are afraid of encountering the kind of situation that Fang Yan said, and if they encounter a high level, they may be easily cured, but if they encounter a poor level, they may be treated more seriously.

This situation makes many patients who believe in traditional Chinese medicine daunting.

The classrooms are full of students studying Chinese medicine, and many of them still have dreams when they are students, and most of them have hopes and aspirations for Chinese medicine.

The current situation of Chinese medicine makes many students a little unsure of what to say.

"Therefore, the future of Chinese medicine lies in everyone."

Fang Yan looked at everyone and said slowly: "I hope that all the younger brothers and sisters can study medicine well, strive to be a good Chinese medicine doctor, and change the status quo of Chinese medicine in the future. ”

After that, Fang Yan looked at the male classmate in front of him again: "Today, I will use this case to tell you whether this disease is difficult or not, and whether it is difficult to learn Chinese medicine." ”

Saying that, Fang Yan asked the male classmate: "In addition to itching, are there any other uncomfortable feelings?" ”

"In addition to itching, there is also a fear of wind and cold, and when you encounter cold wind, it will be more serious." The male classmate said.

"Many students should know what this illness is, right?" Fang Yan asked.

"Rubella." Some classmates said loudly.

"Not bad, rubella."

Fang Yan nodded: "Rubella itching meets wind and cold, this is an external infection, and it belongs to the wind chill ......."

In his Treatise on Typhoid Fever, Zhang Zhongjing divided the manifestations of solar wind chill into two categories: solar stroke and solar typhoid fever, and the main characteristic of solar stroke is sweating. The main characteristic of solar typhoid fever is that there is no sweating, and the pulse is tight......"

Saying that, Fang Yan asked the male classmate to stretch out his hand and check the male classmate's pulse.

"The inch pulse is slightly floating, neither floating pulse nor floating tight ......."

After diagnosing the pulse, Fang Yan said slowly: "And the main manifestation of the patient is bad wind and cold, it seems that it is difficult to further judge whether it is a solar stroke or a solar typhoid fever......

Fang Yan paused as he spoke: "But don't forget, in "Treatise on Typhoid Fever", in addition to the two basic symptoms of solar stroke and solar typhoid fever, there is also a special type of symptoms, does anyone know what it is?" ”

Many students below raised their hands.

Fang Yan ordered a female classmate in the front row.

"It's a mild form of sun-episodic depression." The female classmate said.

"Yes, it's a mild illness of sun depression."

Fang Yan nodded, asked the female classmate to sit down, and asked again, "When you get here, does anyone think of something?" ”

There were scattered classmates below who raised their hands, and Fang Yan nodded another male classmate in front.

"Sun disease, learned that eight or nine days, such as abuse, fever and cold, heat and cold, more and less cold, his person does not vomit, clear the stool can be free, two or three times a day. The pulse is slow, and the desire to heal is also. Those who have a weak pulse and are cold, this yin and yang are both weak, and they should not sweat more, go down, or vomit more; If the complexion is hot, and you don't want to solve it, you can't sweat a little, and your body will be itchy, and you should have half a soup of cinnamon and ephedra. The male classmate said.

"You may be seated."

Fang Yan asked the male classmate to sit down and said, "This is the article in the treatise on typhoid fever, which clearly explains the symptoms and treatments.......

"Senior Fang Yan, that's not right."

A classmate said loudly: "It is true that the article says that the sun disease is mild, but now his situation does not match." ”

"Eight or nine days." Other students shouted along.

This article of the treatise on typhoid fever is about a process of typhoid fever, and typhoid fever has not been cured by eight or nine days, such as abuse, and then what kind of situation it is, what kind of medicine is used.

But now the male classmates have been suffering from hives for a year, and they do not meet the rules.

"As I said before, I hope you read more, but not to read dead books, but also to understand, to learn to draw inferences from one example."

Fang Yandao: "In this article, Zhang Zhongjing lists three situations for the later outcome of sun disease.......

"One is the illusion that the pulse is going to tighten and slow down, for the external sensation to go, and the disease is going in the direction of healing, the second is that the evil and the right have been fighting for a long time, the evil has not gone and the positive has been injured, which is manifested as the existence of the good and the evil, and the correct and the table should be corrected, and the third is the stalemate of the evil and the positive and the external depression, the yang qi is depressed (fu), and the qi and blood are unfavorable and the face is red and the body is itchy......."

Saying that, Fang Yan glanced at it: "These three situations are summarized by the ancients in long-term observation, typhoid fever in most cases, even if there is no medicine, in seven or eight days, there is a probability of improvement, that is, the three situations mentioned in the article, either get better, or the evil spirit wins, or stalemate, and the expression is depressed and incomprehensible......"

"Everyone is studying Chinese medicine, and they should know what it means to be depressed."

Saying that, Fang Yan turned around and drew a line on the blackboard: "If this line is skin, then the top is the surface, and the inside is the inside, whether it is from the inside to the outside or from the outside to the inside, there will be a process from the surface to the inside, or from the inside to the surface." ”

"We all know that the human body has a health system, so when good and evil are from the outside in, they will encounter resistance, and when they are discharged from the inside out, the evil qi will also fight, which will cause a process, that is, the evil qi will not move to the extent that it is not counted in the inside, and the surface is not counted in the surface, which is half the surface and half the inside."

"And the evil qi can't come out between half the surface and half the inside, that is, the surface is depressed, because at this time, the good and evil are fighting, the evil spirit doesn't want to go out, the righteous spirit has to resist, and the stalemate, the evil spirit is between half the surface and half the li, so what will happen?"

As he spoke, Fang Yan looked at all the classmates.

In an instant, many students raised their hands.

"You come on." Fang Yan ordered another female classmate.

"At this time, it is easy to develop some skin diseases such as rash, rubella or itchy skin." The female classmate said.

"That's a good answer, please be seated."

Fang Yan nodded and said, "Yes, because half of the surface and half of the inside is right in the position of the skin, and the evil qi belongs to the state of being half out of the skin, so the symptoms are often easy to manifest on the skin, so clinically, most skin diseases can be classified into the category of half surface and half inside, that is, the surface is depressed." ”

"Wori!"

"Now I get it."

Many students suddenly realized.

Fang Yan combined the graphics and explained very straightforwardly, which made many students understand very clearly and intuitively what is the expression depression, why the expression depression is manifested on the skin, rashes, itching and so on.

If the evil spirit wants to go out, it must pass through the skin, and it can't come out halfway, and it is between half the surface and half the inside, isn't it just manifested on the skin?
