Chapter 274 On Medicine

  After dinner, study.

  Zhang gave lectures as usual, Xu Guangling attended lectures as usual, and Chen Zhihe routinely punished him.

  Well, in the words of his old father, being able to stand in this study is already a blessing that has been cultivated in eight lifetimes.

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

  The old man cherishes time very much. When he is not gossiping, he never speaks a word of nonsense. Of course, it can also be said that it is serious and solemn.

   "If you go to the wild to see."

   "You will find that birds eat wild grain ears, animals dig up wild grain roots and eat, such as monkeys and squirrels, they eat wild fruits."

   "Collecting edible plants, grains, etc., to wrap the belly and prolong life, this is the instinct of animals, and it is something they are born to do. This is the case with animals, and human beings as beasts are no exception."

   "The difference between beasts and beasts is that they have an extra layer of clothing."

   "This coat represents civilization, discovery, refinement, and higher aspirations and pursuits."

   "Therefore, in the genus of plants, for humans, there are two types of food, one for food and the other for medicine."

   "Food is daily, medicine is expedient."

   "Food is common, medicine is special."

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

   "Humble words, this is the first point I told 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 analyzed all the ingredients around him through Shennong Jue, and he had a personal understanding of this point. For example, lotus root can relieve cough and moisten dryness, and kiwi fruit can reduce lipids and blood pressure. These are all "medicinal uses", but these two are ingredients in themselves.

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

   But at the same time, there will be no major side effects like medicinal herbs.

   After nodding, Xu Guangling did not hide it, but reported his understanding of this aspect to the teacher.

  Old Zhang nodded lightly after hearing this.

   This is also a statement that the old man is used to.

   "Speaking of medicine, we can't help but say "Shen Nong's Materia Medica"."

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

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

   "Top grades are nourishing."

   "Non-toxic, multi-use, long-term use will not hurt people."

   "The middle grade is harmony."

   "Non-toxic, slightly poisonous, use at your discretion."

   "Lower grades are attacking."

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

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

   Xu Guangling nodded.

   It’s hard to say forever, but at least for the next one or two thousand years, this division method cannot be broken.

   "And under these three divisions, Shennong's Materia Medica also proposed the first principle of drug use."

   "That is, 'the monarch, ministers and envoys'."

   "The monarch is the ruler and the most important one, corresponding to the 'top grade' in Materia Medica."

   "The minister is cooperation, the one who cooperates with the ruler and is the yin and yang of each other, 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 the milk to ferment it into yogurt, which has a better taste."

   "This is the cooperation between the monarch and his ministers."

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

"Secondaries and envoys each undertake their own missions and functions, such as Yanzi's envoy to Chu, Baogong handling cases, etc., and so on. These are not required to be 'general materials', but preferably 'partial materials'. It has a unique and significant unilateral effect."

   "All the compatibility of medicines is carried out under the framework of 'monarch, ministers and envoys'."

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

   "This is my third point."

   "And the fourth point I want to talk about next is some common and special phenomena that have occurred in the process of combining monarchs, ministers, assistants and envoys."

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

   "The monarch has a counselor by his side, who is also very capable, and he is also very appreciated by the monarch."

   "But this minister and this advisor are eating each other in the same groove, but they are extremely disliked by each other. The minister rebuked the advisor for being a fortunate villain, and the advisor rebuked the minister for being narrow-minded and intolerant of others."

   "So if the monarch makes these two men whom he valued complicity in one thing, the result will be quite bad."

   "This is a phenomenon in the compatibility of medicines, which is called 'mutual evil', that is, both are good medicinal materials, but they cannot be used together. They will dismantle 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 follow each other, one master and the other cooperate tacitly and are handy, and some are like husband and wife, the husband is very strong, and the wife is very weak, but the weak wife can hold the strong. 's husband, making it soft around his fingers."

   "Shen Nong's Materia Medica calls these relationships the 'seven emotions'."

   "Specifically, it means 'one-way, mutual beard, mutual envoy, mutual fear, mutual evil, mutual killing, opposite'."

After saying this, Zhang Lao paused, then got up, picked up a scroll from the side of the desk, hung it on the main wall of the study, and slowly unfolded it from left to right, but it was a huge map of China, the key point in the map. It shows the landscape of mountains and water.

   Well, there are only landscapes.

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

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

   "Humble words, 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 temperature is in general throughout the year. Relatively speaking, the environment for the growth of plants and trees is also worse."

   "As the saying goes, 'The spring in Wuyuan is old and late, and in February the poplars have not hung silk. That is, the day when the riverside ice is blooming is the time when the flowers in Chang'an are falling.'"

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

   "And this vitality, expressed in the herb, means that it is multi-nutritious and nourishing."

   "So, from the north and the south, 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."

   "This is the general picture."

  …

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

   After an hour, this lesson ends.

   and pass this lesson.

  Xu Guangling knew that food and medicine have the same origin and different uses.

  Xu Guangling learned that medicine is divided into three grades.

  Xu Guangling learned about the relationship between the monarch, ministers and envoys and Qiqing between medicines.

   In Xu Guangling's mind, there was an overview map of Chinese landscapes and 1,862 kinds of medicinal herbs generated around this map.
