Бэньцао ганму: Энциклопедия традиционной китайской медицины

Chinese herbology book

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. 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 than a medical work and that a tale of the strange could illustrate a drug's effects. The Ming dynasty emperors did not pay too much attention to his work, and it was ignored. Li's work contained errors and mistakes due to his limited scientific knowledge at the time. For example, Li claimed that all otters were male

The title, translated as "Materia Medica, Arranged according to Drug Descriptions and Technical Aspects", uses two Chinese compound words. Bencao (Pen ts'ao; "roots and herbs; based on herbs, pharmacopeia, materia medica") combines ben (lang=zh 'origin, basis') and cao (lang=zh 'grass, plant, herb'). Gangmu (Kang mu; 'detailed outline; table of contents') combines gang (kang; lang=zh 'main rope, hawser; main threads, essential principles') and mu (lang=zh 'eye, look; category, division'). The characters lang=zh and lang=zh were later used as 'class' and 'order', respectively, in biological classification.

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 1596, 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.

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 quicksilver (mercury) and lead were not toxic. 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.
