Compendium of Materia Medica

The Compendiumof Materia Medica (Chinese: 本草綱目; pinyin: Běncǎo Gāngmù) is a pharmaceutical text written by Li Shizhen(1518-1593AD) during the Ming Dynastyof China.

The text is regarded as the most complete and comprehensive medical books ever written in the history of traditional Chinese medicine. The text lists all the animals, plants and other objects which were believed to contain medicinal properties.

History

Li Shizhen completed the first draft of the text in 1578, after conducting readings of 800 other medical reference books and carrying out 30 years of field study. A famous proverb originated from the field studies of Li: 不耻下问, as he was never ashamed of asking and learning from the less educated people about medicine. For this and many other achievements Li Shizhen is being compared to the Shennong, a mythological God in Chinese myth who taught them about agriculture and herbalmedicine.

Contents

The Compendium of Materia Medica has 52 volumes in total:

1. At the very beginning is the table of contents, containing a list of entries included and 1,160 hand drawn diagrams to serve as illustration.

2. Volume 1 to 4 — an 'index' (序例) and a comprehensive list of herbs that would treat the most common sickness (百病主治药).

3. Volume 5 to 52 — the main content of the text, containing 1,892 distinct herbs, of which 374 was added by Li himself. There are some 11,096 side prescriptionsto treat common illness (8,160 of which is compiled or collected by Li).

The text is written in almost 2 million Chinese characters, classified into 16 divisions and 60 orders. For every herb there are entries on names, detailed description of appearance and odor, nature, medical function, effects and side recipes etc.

Value

With the publication of the Compendium of Materia Medica, not only did it improve the classification of how traditional medicine was compiled and formatted, but it was also a great medium in improving the credibility and scientific values of biology classification of both plants and animals.

The compendium corrected many mistakes and false understandings of the nature of herbs and illness. Li also included many new herbs, added his own discovery in certain drugs, their effectiveness and function, as well as more detailed description according to experiments. It also has notes and records on general medical data and medical history.

Compendium of Materia Medica is also more than a pharmaceutical text, for it contains information so vast that it covered topics in biology, chemistry, geography, geology, history, and even miningand astronomy, which would seem to have little to do with herbal medicine. It has been translated into more than 20 languages and spread all over the world. Even now it is still in print and used as a reference book.
