Omniscient and Almighty

Chapter 274 On Medicine

After dinner, study.

Zhang Lao gave lectures as usual, Xu Guangling attended lectures as usual, and Chen Zhihe was punished as usual.

Well, in the words of his old father, being able to stand in this study room is already a blessing from eight lifetimes of cultivation.

Yesterday, Zhang Lao said that today he will talk about "medicine".

The old man cherishes time very much, and he never speaks nonsense when he is not gossiping. Of course, it can also be said that this is seriousness and solemnity.

"If you go to the wild to see."

"It will be found that birds eat the ears of wild grains, and animals dig the roots of wild grains to eat, such as monkeys and squirrels, which eat wild fruits."

"Collecting edible plants, trees, and grains to wrap their stomachs and extend their lives is an animal's instinct and something they are born to do. Animals are like this, and humans, as beasts in clothes and clothes, are no exception."

"The difference between a beast in clothes and a beast is that there is an extra layer of clothes."

"This layer of clothing represents civilization, discovery, sophistication, and higher yearning and pursuit."

"That's why, in the genus of vegetation, for humans, there are two types of food, one is food, and the other is medicine."

"Food is daily, medicine is expedient."

"Food is common, medicine is special."

"Food and medicine have the same origin, but have different uses."

"Zhuoyan, this is the first point I'm going to tell you today, that is, 'Food and medicine have the same origin' and 'Food and medicine have different uses'."

Xu Guangling nodded.

Some time ago, he used the Shennong Jue to analyze all the ingredients around him, and he has a personal understanding of this point.For example, lotus root can relieve cough and moisten dryness, and kiwi fruit can reduce fat and blood pressure. These are both "medicinal", but these two are ingredients in themselves.

The medicinal effect of the ingredients will not be that strong.

But at the same time, there will be no such large side effects as medicinal materials.

After nodding, Xu Guangling didn't hide it, but reported his understanding of this aspect to the teacher.

Zhang Lao nodded lightly after hearing this.

This is also the attitude of the old man.

"When you talk about medicine, you have to talk about "Shen Nong's Materia Medica"."

"This is the first treatise on medicine since the beginning of our civilization, and it is also the one with the highest theoretical level even up to now. For thousands of years, no one can surpass it."

"In Shennong's Materia Medica, 'Materia Medica' is divided into three types, or three grades."

"The top grade is nourishing."

"Non-toxic, it won't harm people if taken frequently or for a long time."

"Middle grade is harmony."

"Non-toxic, slightly toxic, use with discretion."

"The lower grade is attack."

"Toxic, even highly toxic, use with caution."

"Zhuoyan, this is also the second point I want to tell you today. Because of their different properties and functions, medicinal herbs are divided into three grades: upper, middle and lower. The division of these three grades can span all medicines, and can also be used in ancient and modern times. China and foreign countries, as well as the future, until eternity."

Xu Guangling nodded.

It's hard to say forever, but at least within the foreseeable 2000 years, this division method cannot be broken.

"Under these three divisions, Shennong's Herbal Classic also proposed the first principle of drug use."

"That's 'junchenzuoshi'."

"Jun is the master, the most important one, corresponding to the 'top grade' in Materia Medica."

"The subject is coordination, the one who cooperates with the monarch and is yin and yang, corresponding to the 'middle grade' in Materia Medica."

"Like milk."

"Some people want to drink milk because of nutrition, but they don't like the taste, so the merchants add probiotics to milk to ferment it into yogurt, which has a better taste."

"This is the cooperation between the king and the minister."

"Jun + minister is also the most common means of drug compatibility."

"Associates and envoys each take on their own missions and functions, such as Yan Zi envoy Chu, Bao Gong to handle cases, etc. This is the case. Such genus does not need to be 'general material', but it is better to be 'biased material', have a unique and significant unilateral effect."

"All the compatibility of drugs is carried out under the framework of 'monarch, subject, assistant and envoy'."

"Whether it is two medicines, twenty medicines, or two hundred medicines in a large formula, this most basic principle must be followed."

"This is my third point."

"And the fourth point I'm going to talk about next is some common and special phenomena that appear during the matchmaking process of monarchs, ministers and assistant envoys."

"A minister, he is very capable, and he is also very appreciated by the monarch."

"There is a counselor beside the monarch, who is also very capable, and is also very appreciated by the monarch."

"However, this minister and this counselor, eating together, are extremely disliked by each other. The minister denounces the counselor as a lucky villain, and the counselor denounces the minister as being narrow-minded and unable to tolerate others."

"So if the monarch lets these two of his highly regarded subordinates conspire in one thing, the result will be quite bad."

"This is a phenomenon in the compatibility of medicines, called 'mutual evil', that is, two medicines are obviously good medicines, but they can't be used together, they will destroy each other and destroy each other."

"The relationship between drugs and drugs is also like the relationship between people."

"Some admire each other, some hate each other, some obey each other, one master and one pair cooperate tacitly, handy, some are like husband and wife, the husband is strong, the wife is weak, but the weak wife can hold the strong Husband, turn it into soft fingers."

"Such relationships are called 'seven emotions' in Shennong's Materia Medica."

"Specifically, it means 'one-way, must, make each other, fear each other, hate each other, kill each other, opposite'."

After saying this, Zhang Lao paused, then stood up, picked up a scroll from the side of the desk, hung it on the front wall of the study, and then slowly unfolded it from left to right, but it turned out to be a huge map of China, the key points in the map It shows the landforms of mountains and water.

Well, there are only mountains and rivers.

In other words, this is the first time Xu Guangling has looked at a map of China seriously.

And through this map, the mountains and water veins on this land are clear at a glance.

"Zhuo Yan, let me briefly tell you about herbs and geography." Standing in front of the map, Zhang Lao pointed to the map and said.

"In the north, the further north you go, the less sunlight you get, and the lower the general temperature throughout the year. Relatively speaking, the growing environment for vegetation is also worse."

"As the saying goes, 'The spring in Wuyuan is old and late, and the weeping poplars are not hanged in February. That is to say, the day when the ice blooms by the river is the time when the flowers fall in Chang'an.'"

"In order to resist the harsh growth environment, plants need to have strong vitality."

"And this kind of vitality is manifested in medicinal herbs, which means that it is more nutritious and more nourishing."

"So, taking the north and the south together, the northern herbs are more nourishing, while the southern herbs are more harmonious. For the same reason, the high mountain herbs are more nourishing, the low mountain herbs are more harmonious, the land herbs are more nourishing, and the water herbs are more harmonious."

"That's the general picture."

……

Next, Zhang Lao revolved around the mountains and water veins on the map, from north to south, from east to west, and talked about them one by one.

After an hour, the class ends.

And through this class.

Xu Guangling knew that food and medicine come from the same source but have different uses.

Xu Guangling knew that there are three grades of medicine.

Xu Guangling understood the relationship between the monarch, his ministers, his assistants and the seven emotions in medicine.

In Xu Guangling's mind, there was an overview map of China's mountains and rivers, and 860 kinds of medicinal herbs generated around this map.
