Thank you for viewing. The "Compendium of Materia Medica" (Honzo Komoku) is a Chinese encyclopedic herbal book[1]. In the history of herbal studies, it is considered a representative work of China, given the scale of items listed and cited references. During the Wanli Emperor's reign in the Ming Dynasty, the herbalist Li Shizhen completed the manuscript by 1578, and after revisions, it was finally published in 1596. It is a pharmaceutical encyclopedia that classifies and compiles medicinal herbs, but it also conveys valuable information as a botanical encyclopedia beyond medicinal herbs. Along with the "Complete Writings on Agriculture" and the "Chongzhen Calendar," it demonstrates the high academic standards of the Ming Dynasty. The author is Li Shizhen (1518-1593) of the Ming Dynasty, who completed the manuscript around 1578 (the 6th year of Wanli), and it was published in Nanjing in 1596 (the 23rd year of Wanli) after his death. Li Shizhen spent 26 years writing this book, investigating over 700 documents, and described about 1900 kinds of drugs, combining his own research. Subsequent herbal books after China's "Shennong Ben Cao Jing" followed a common principle: when supplementing and revising previous herbal books, they did not directly alter the writings of their predecessors, but instead stated differing opinions within new annotations. However, the "Compendium of Materia Medica" has a completely new composition based on its own unique views. In 1951, it was included in the historical record of world cultural figures at the World Peace Conference in Vienna[4]. Furthermore, it was registered in the "Memory of the World" at a UNESCO conference held from May 22 to 25, 2011. It was also brought to Japan, and Kaibara Ekiken of the Edo period researched Japanese medicinal herbs based on the "Compendium of Materia Medica" and wrote the "Yamato Honzo" (1709), developing herbal studies.
