Li Shizhen traveled through 400 years to read the engraved edition of the Compendium of Materia Med

Today, let's talk about Li Shizhen.

How to write a compendium of materia medica.

Li Shizhen was an outstanding medical scientist in the Ming Dynasty of our country, the number is near the lake, the word Dongbi, he wrote the "Compendium of Materia Medica" after 27 years of hard work

He has made great contributions to the development of pharmacology in later generations. <>

Li Shizhen began to write this book when he was 37 years old, he was 61 years old when he finished writing, and it took 27 years, and Li Shizhen wrote the Compendium of Materia Medica, referring to 1,000 kinds of works, Li Shizhen revised the Compendium of Materia Medica three times, and it was finalized in the end, and he interviewed thousands of people to walk tens of thousands of miles in order to finish writing this book.

Li Shizhen decided to write the Compendium of Materia Medica at the age of 34, and she also spent her whole life for this book, because he knew that medicine was related to human life, and he was very cautious when writing, and if he encountered something he didn't understand, he would go to the field to investigate.

Li Shizhen heard that there was a poisonous snake in his hometown, this poisonous tongue is a very valuable medicinal material, and in order to find out what this kind of thing looks like and what he likes to eat, he went to Longfeng Mountain, the origin of this snake, to conduct field investigations. <>

Longfeng Mountain is dangerous and high, Li Shizhen risked his life with the help of snake catchers, climbed to Longfeng Mountain, and came to a cave overgrown with weeds, in the cave, he finally saw this fierce snake with his own eyes, this snake is full of white flowers on a black background, and is eating a wild vine called "heather".

And here, Li Shizhen also saw with his own eyes how snake catchers don't do such things, and then spread out the snake and washed it and made the snake into medicinal materials.

Later, Li Shizhen remembered in detail the shape and origin of this snake, as well as living habits, medicinal value, etc., based on his own personal experience, and also corrected and revised some incorrect statements about this snake in many medical books.

In the past, people also said that pangolins.

It can be made into medicinal materials, but there is very little understanding of pangolins, so Li Shizhen went to the mountain with a few hunters and woodcutters and caught the pangolin. <>

But how do pangolins eat ants? Li Shizhen went to the mountains again to continue to observe, until he saw with his own eyes that the pangolin opened the ant nest, then put his head into it, and licked the ants with his tongue to eat, and later he also recorded these things in detail in his "Compendium of Materia Medica".

Li Shizhen's father was a doctor. He treats poor patients and never cares about the cost of consultations. Under the influence of his father, Li Shizhen was determined to be a good doctor when he was a child and serve the health of the working people.

When he was young, Li Shizhen set up an ambition to rewrite a pharmacological "materia medica" in ancient China. In order to realize his ideals, Li Shizhen fought against the Taoist priests who pretended to be ghosts, the mediocre King of Chu, and the corrupt bureaucrats of the Tai Hospital. He read a large number of ancient books, visited folk earthworks, went to the remote mountains to collect medicines, and finally, compiled a large pile of materials, and spent 27 years before and after, and finally wrote the famous "Compendium of Materia Medica".

This work of more than 1 million words, with 1,892 kinds of medicines, more than 11,000 prescriptions and 1,160 illustrations, can be said to be the culmination of the integration of Chinese medicine in China at that time, which not only brings together the essence of previous pharmaceutical works, but also makes some corrections and criticisms of the erroneous and untrue information and conclusions of some pharmaceutical books in the past.

Li Shizhen used the efforts of his life to personally test the medicine, and then wrote this compendium of materia medica, coupled with his continuous study, and constantly to treat people, and finally wrote such a classic book.

Mainly based on the analysis of what I have seen and seen, and I have also studied some herbs and incurable diseases, and slowly wrote this book, which has a very strong influence on the present.

In fact, it is also based on my own experience and my own subsequent learning that I have judged the medicinal properties of the drug, and I can write it.

The process was quite hard, he read a lot of medical books, and he also tasted a lot of herbs himself, so he was able to compile such a book, which can be seen that the doctor is benevolent and very great.

How did Li Shizhen compile the Compendium of Materia Medica?

Since 1565, Li Shizhen has gone to Wudang Mountain, Lushan, Maoshan Mountain, Niushoukong Mountain, Huguang, Anhui, Henan, Hebei and other places to collect drug specimens and prescriptions, and worship fishermen, woodcutters, farmers, coachmen, pharmacists, snake catchers as teachers, refer to 925 kinds of books on medicine and other aspects of the past dynasties, archaeological evidence, exhaustive study of physics", record tens of millions of words of notes, and figure out many difficult problems in the dismantling of the book. After 27 cold and summer, the manuscript was changed three times, and the 1.92 million word masterpiece "Compendium of Materia Medica" was completed in the eighteenth year of Wanli in the Ming Dynasty (1590).
