How did the ancients know the medicinal properties of a thing?

I think that the ancients understood the properties of medicine in the practice of life, which came from their careful observation and collection.

First of all, in order to survive, they discovered the characteristics of various foods in the process of searching for food, such as preying on sheep and knowing that mutton heat has a tonic effect, people with normal bodies cannot eat more; Prey to pigs and learn that pork is cold, people with diarrhea can not eat, and because people are omnivorous, they will taste the seeds and fruits of plants and learn that millet is warm, wheat is sweet and slightly cold, corn is cold, etc., people will know it as soon as they eat it, and they will remember it and then use the text to record it.

In the process of looking for food, I also found the medicine, because the medicine and food are of the same origin, tasting herbs is the behavior of the people, accumulating over time, and getting the collection and compilation of the book by the people who have a heart, in order to make the book authoritative, so the name Shennong Emperor, so there is "Shennong's Materia Medica".

A book came out. <>

Ming Dynasty pharmacologist Li Shizhen.

It is a perennial extensive collection of folk medicines to become famous, he spent his whole life to visit the people who collect medicines, and search for folk prescriptions, consult information, accumulate into a book, and he carefully analyzed and summarized the "Compendium of Materia Medica".

This huge work of medicine is called the encyclopedia of ancient China by the West, and the "Compendium of Materia Medica" has been translated and used by many countries around the world for many times.

There is also a medicine that was observed and obtained by the ancients, such as the white flower snake tongue grass.

It was a person who saw an injured white snake eat a kind of grass and got better, so people called this grass the white flower snake tongue grass.

There is also a kind of medicine that people associate with analogy, such as comparing the limbs of the human body to the branches, the cinnamon branch can cure the pain of the limbs through the arm, and the same is true for mulberry branches; Chicken inner gold.

It is the stomach of chickens that is used to cure stomach problems.

There are more than 5,000 kinds of 700 species, and now the "Chinese Materia Medica".

Nearly 9,000 species, more and more, more and more abundant.

The ancients wanted to know the medicinal properties of a thing, which they needed to know through practice, and only through countless experiences could they summarize the characteristics of various drugs.

It is up to the doctors, after eating it, to know the effect of the medicine according to the biological characteristics it exhibits.

People continue to try in life, and come to experience, the medicinal properties are the best in the human practice of major Chinese medicine practitioners, and the efficacy is certain.

How does traditional Chinese medicine play its best role? - The basis for the role of traditional Chinese medicine is the Chinese medicine.

Buy the four qi and five flavors that are often said in school.

The so-called four qi refers to the cold, heat, warm and cold of traditional Chinese medicine.

Four different properties (called four qi in Chinese medicine).which is warm.

It is of a different nature from cold. And warm and hot, plugged.

It has commonality with Liang, respectively; Temperature is second to hot and cool.

Yu Han, that is to say, there is a degree in the common nature.

differences. For some drugs, it is usually also marked with a fever.

Words such as big cold, slightly warm, and slightly cold are distinguished. Medications.

Cold, heat, warmth, and coolness are the effects of drugs on the body.

The reaction that occurs is generalized in relation to the disease treated.

Cold and hot properties are relatively speaking. Able to reduce or eliminate heat syndrome.

The drugs are generally cold or cold, such as skullcap and plate.

Blue root has heat clearing and detoxification for fever, thirst, sore throat and other heat syndromes.

effect, indicating that both drugs have cold properties. The opposite is possible.

Drugs that alleviate or eliminate cold syndrome are generally warm, such as:

Aconite and dried ginger are cold symptoms such as cold pain in the abdomen and weak pulse.

It has the effect of dissipating cold in warmth, indicating that these two drugs have heat.

Sex. For cold diseases, it is necessary to use hot medicines, and for fever diseases, it is necessary to use hot medicines.

With cold medicine, here the medicinal nature and the disease nature are reversed, the so-called.

On the contrary, this is a specific manifestation of medicine culture.

If "heat is used to cure fever (heat is cured with heat medicine), cold is increased."

cold (using cold medicine to cure cold diseases)", it will lead to "essence and qi inside."

wounded, not seen (now) outside", this is ** on the serious.

Blunder. Sun Simiao seriously criticized in "The Sincerity of the Great Doctor".

Those who are "cold and cold" ( are cold diseases, but use cold to make diseases.

colder), hot and warm (it is a fever, but it is a fever that makes it sick.

hotter)" doctors, if this treatment will not only aggravate.

Illness, and in severe cases, death. It can be seen from this that transport.

How important it is to use the "four qi" of medicine to cure diseases, many.

Those who have taken Chinese medicine may not know much about it.

When it comes to medicine, take Shennong to taste the herbs, taste it and know what the principle is, unless it is really a fairy, the real fairy may not need to taste it at all.

In life, it comes to discover, it accumulates, and so on.

Thank you, in ancient times when technology was not developed, how did the ancients identify medicinal materials and medicinal properties?

In ancient times, the ancients had a lot of time to find and collect medicinal materials, and through continuous attempts or trials on the patient, the curative rhizomes of flowers and plants were recorded one by one, and remembered the shape and smell of the flowers and leaves of the herbs, and then they would not be picked by mistake when collecting. Herbal medicine has been obtained in China for thousands of years by using the practice of clinical practice, and the medicinal properties may also be recorded by patients after taking medicine.

However, in ancient times, it was mostly wild, and now it is mostly planted, and the medicinal effect is much worse...
