The Ben Cao Gang Mu , or Compendium Materia Medica , is an encyclopedic compendium written by the 16th-century Chinese doctor Li Shizhen. This compilation is said to be the most complete and comprehensive medical book ever written in the history of traditional Chinese medicine , bringing together the medical knowledge of East Asia.

The Prince of Pharmacists and the Ben Cao Gang Mu

Although he remains almost entirely unknown in Western culture, Harvard Magazine explains that in China Li Shizhen “is virtually a household name” and a “kind of patron saint of Chinese herbal medicine.” Dubbed the Prince of Pharmacists, this scholar from the Hubei province in central China lived between 1518 and 1593 during the Ming Dynasty (1368 to 1644), investing the last half of his life researching and writing his most important work, the Ben Cao Gang Mu . Unfortunately, he died before it was published, and it was thanks to his sons and grandsons that the famed treatise was published in 1596.

This incredible piece of work, which contains 52 volumes, took 27 years to complete. It’s jam-packed with information taken from a wide range of contemporary sources. It includes descriptions, poems, histories, and recipes and remedies for using everything you can imagine as a medicine, from turtles and ginseng, to shellfish and human body parts. There are descriptions of 1,094 herbs, as well as hundreds of animal and mineral substances. In fact, this fabulous medicinal book includes 1,892 drugs and 11,096 prescriptions. It also contains hundreds of exquisite hand drawn diagrams.

Besides being a book on medicine, the Ben Cao Gang Mu also deals with natural history, giving a classification of mineral, vegetable, and animal products. If this were not enough, it includes chapters on chemical and industrial technology, as well as geographical, historical, dietetic, culinary, cosmological, philosophical, and philological data.

The Importance of the Ben Cao Gang Mu

In 2011, the  Ben Cao Gang Mu  received global recognition when it was included in UNESCO’s Memory of the World Register. A copy of the compendium that was block-printed in 1593 by Hu Cheng-Long in Jinling (modern Nanjin city in Jiansu Province, China), is kept in the Library of the China Academy of Chinese Medical Sciences. But, why is the  Ben Cao Gang Mu  so important?

It has been claimed that this piece of work, and the empirical approach employed by Li in his research and fieldwork have profoundly influenced the development and study of modern natural science. For instance, classification standards and the way  materia medica  should be compiled and formatted were laid down for the first time. This has been crucial in enhancing the credibility, scientific value, and accuracy of the biological classification of both flora and fauna.

Its importance is also evident in the fact that it has been translated into all the languages of the Far East, as well as the principal Western languages. Despite being over 400 years old, the  Ben Cao Gang Mu  is still being used as a monumental reference work. Thus, the longevity of this work and its influence beyond the borders of its land of origin demonstrates that this was an incredible achievement.

Nothing is Perfect: Factual Errors in the Ben Cao Gang Mu

Nevertheless, there are some notable factual errors in the  Ben Cao Gang Mu . For instance, lead was claimed to be non-toxic, otters were apparently “always male,” and the Moupin langur, or golden snub-nosed monkey, were 10 feet (3 m) tall, had backwards feet and could be caught when it drew its upper lip over its eyes.

These errors, however, may be attributed to the limitations of scientific and technical knowledge at the time Li Shizhen wrote his famed medical book. Fortunately, they have been corrected. I suppose this demonstrates the cumulative nature of human knowledge, which one generation builds upon the achievements of its predecessors. It is this process of accumulation that has allowed us to attain the technological progress that we enjoy today.

Taking its name from the original masterpiece, the  Ben Cao Gang Mu  was performed by the popular Taiwanese singer Jay Chow on his album  Still Fantasy . While its lyrics deal with Chinese pride, the aspect of the song I found most amusing was that Jay Chow rapped his way through the references to Chinese herbal medicine ! So, anyone up for rapping Pliny’s Natural History ?
