The Ben Cao Medical Book (also known as Compendium of Materia Medica or Ben Cao Gang Mu; Chinese: 本草纲目) is the most famous and comprehensive medical book ever written in the history of traditional Chinese medicine (TCM). Compiled and written by Li Shi-zhen (1518~1593), a medical expert of the Ming Dynasty (1368-1644) over 27 years.
The Ben Cao Medical Book records and describes all the plants, animals, minerals, and other objects that were believed to have medicinal properties in TCM. The book reflects the pharmaceutical achievements and developments of East Asia before the 16th century. On the basis of his predecessors’ achievements in the pharmacological studies, Li contributed further by supplementing and rectifying many past mistakes and misconception in relate to nature of many medicinal substances and causes of various illnesses. Charles Darwin, originator of the biological theory of evolution, regards the book as the “ancient Chinese encyclopedia”.
