Ben Cao Gangmu

The ''Bencao gangmu'', known in English as the ''Compendium of Materia Medica'' or ''Great Pharmacopoeia'', is an encyclopedic gathering of medicine, natural history, and Chinese herbology compiled and edited by Li Shizhen and published in the late 16th century, during the Ming dynasty. Its first draft was completed in 1578 and printed in Nanjing in 1596. The ''Compendium'' lists the '' materia medica'' of traditional Chinese medicine known at the time, including plants, animals, and minerals that were believed to have medicinal properties. Over the centuries it was reprinted, translated, and cited widely. In the twentieth century was adopted as a basis for Traditional Chinese Medicine.

Li compiled his entries not only from hundreds of earlier works in the ''bencao'' medical tradition, but from literary and historical texts. He reasoned that a poem might have better value that a medical work and that a tale of the strange could illustrate a drug's effects.

Name

The title, translated as "''Materia Medica'', Arranged according to Drug Descriptions and Technical Aspects", uses two Chinese compounds. ''Bencao'' (''Ban-chao''; "roots and herbs; based on herbs, pharmacopeia, ''materia medica''") combines ''ben'' ( 'origin, basis') and ''cao'' ( 'grass, plant, herb'). ''Gangmu'' (''Kang-mu''; 'detailed outline; table of contents') combines ''gang'' (''kang''; 'main rope, hawser; main threads, essential principles') and ''mu'' ( 'eye, look; category, division').

The characters and were later used as 'class' and 'order', respectively, in biological classification.

History

Li Shizhen travelled widely for field study, combed through more than 800 works of literature, and compiled material from the copious historical ''bencao'' literature. He modelled his work on a Song dynasty compilation, especially its use of non-medical texts. He worked for more than three decades, with the help of his son, Li Jianyuan, who drew the illustrations. He finished a draft of the text in 1578, the printer began to carve the blocks in 1593, but it was not published until 1593, three years after Li died. Li Jianyuan presented a copy to the Ming dynasty emperor, who saw it but did not pay much attention. Further editions were then published in 1603, 1606, 1640, and then in many editions, with increasing numbers of illustrations, down to the 21st century.

Contents

The text consists of 1,892 entries, each entry with its own name called a ''gang''. The ''mu'' in the title refers to the synonyms of each name.

The ''Compendium'' has 53 volumes in total:

#The opening table of contents lists entries, including 1,160 hand drawn diagrams and illustrations.
#Volume 1 to 4 – an index () and a comprehensive list of herbs to treat the most common sicknesses ().
#Volume 5 to 53 – the main text, contains 1,892 distinct herbs, of which 374 were added by Li Shizhen. There are 11,096 side prescriptions to treat common illness (8,160 of which are compiled in the text).

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

Errors

The text contains information that was proven to be wrong due to Li's limited scientific and technical knowledge. For example, it is claimed that lead is not toxic. Li also claimed that otters are only female and that the Moupin langur is tall, has backwards feet and can be caught when it draws its upper lip over its eyes.

Evaluation

The British historian Joseph Needham writes about the Compendium in his Science and Civilisation in China.Needham, Joseph, and Wang Ling (1954), ''Science and Civilisation in China, Volume 1 Introductory Orientations'', Cambridge University Press, p. 47.

The text provided classification of how traditional medicine was compiled and formatted, as well as biology classification of both plants and animals.

The text corrected some mistakes in the knowledge of herbs and diseases at the time. Several new herbs and more details from experiments were also included. It also has notes and records on general medical data and medical history.

The text includes information on pharmaceutics, biology, chemistry, geography, mineralogy, geology, history, and even mining and astronomy.
