Li Shizhen
Li Shizhen (July 3, 1518  – 1593), courtesy name Dongbi, was a Chinese acupuncturist, herbalist, naturalist, pharmacologist, physician, and writer of the Ming dynasty. He is the author of a 27-year work, found in the "Compendium of Materia Medica" (Bencao Gangmu (). He developed several methods for classifying herb components and medications for treating diseases. The "Compendium" is a materia medica text with 1,892 entries, with details about more than 1,800 drugs (Chinese Medicine), including 1,100 illustrations and 11,000 prescriptions. It also described the type, form, flavor, nature and application in disease treatments of 1,094 herbs. The book has  been translated into several languages. The treatise included various related subjects such as botany, zoology, mineralogy, and metallurgy. Five original editions still exist. Life. In addition to "Compendium of Materia Medica", Li Shizhen wrote eleven other books, including "Binhu Maixue" ("Pin-hu Mai-hsueh"; ; "A Study of the Pulse") and "Qijing Bamai Kao" ("Chi-ching Pa-mai Kao"; ; "An Examination of the Eight Extra Meridians"). He lived during the Ming dynasty and was influenced by the Neo-Confucian beliefs of the time. He was born in what is today Qizhou, Qichun County, Hubei on July 3, 1518 AD and died  75 years later, in 1593. Li Shizhen' grandfather was a doctor who traveled the countryside and was considered relatively low on the social scale of the time. His father was a traditional physician and scholar who had written several influential books. He encouraged his son to seek a government position. Li took the national civil service exam three times, but after failing each one, he turned to medicine. At 78, his father took him on as an apprentice. When he was 38, and a practicing physician, he cured the son of the Prince of Chu and was invited to be  an official there. A few years after, he got a government position as assistant president at the Imperial Medical Institute in Beijing. However, even though he had climbed the social ladder, as his father had originally wanted, he left a year later to return to being a doctor. In his government position, Li was able to read rare medical books. He began correcting some of the mistakes and conflicting information in these medical publications. He soon began the book "Compendium of Materia Medica" to compile correct information with a logical system of organization. A small part was based on another  book which had been written several hundred years earlier, "Jingshi Zhenglei Beiji Bencao" ("Ching-hsih Cheng-lei Pei-chi Pen-tsao"; "Classified Materia Medica for Emergencies") – which, unlike many other books, had formulas and recipes for most of the entries. In the writing of the "Compendium of Materia Medica", he travelled, gaining first-hand experience with many herbs and local remedies and consulted over 800 books. Altogether, the writing of "Compendium of Materia Medica" took 27 years, which included three revisions. Ironically, writing the book allegedly took a toll on his health. It was rumored that he stayed indoors for  ten consecutive years during the writing of the "Compendium of Materia Medica". After he had completed it, a friend “reported that Li was emaciated.” Li died before the book was officially published, and the Ming emperor at the time paid it little regard. The mineral lishizhenite, described in 1990, is named in his honor. A movie about his life and research on medicine was made in 1956 by Shanghai film studio. Section::::"Compendium of Materia Medica". "Compendium of Materia Medica" was a massive literary undertaking. Li's bibliography included nearly 900 books. Because of its size, it was not easy to  use, though it was organized much more clearly than others that had come before, which had classified herbs only according to strength. He broke them down to animal, mineral, and plant and divided those categories by their source. Dr. S. Y. Tan says: “his plants were classified according to the habitat, such as aquatic or rock origins, or by special characteristics, e.g. all sweet-smelling plants were grouped together.” Li had exemplary recording techniques. Seeking to fix the errors of previous works, the medicinal plants and substances in the "Compendium of Materia Medica" were clearly organized and categorized. With every  entry, he included: "Compendium of Materia Medica" contained nearly 1,900 substances, which included 374 that had not appeared in other works. Not only did it list and describe the substances, but it also included prescriptions for use – about 11,000 - 8,000 of which were not well known. The "Compendium of Materia Medica" also had 1160 illustrated drawings to aid the text. In addition to writing "Compendium of Materia Medica", Li wrote about gallstones, using ice to bring down a fever, and using steam and fumigants to prevent the spread of infection. Li also emphasized preventative medicine. He said that “‘To cure  disease is like waiting until one is thirsty before digging a well...’” and listed over 500 treatments to maintain good health and strengthen the body, 50 of which he invented himself. While only six copies of the original edition remain – one in the US Library of Congress, two in China, and three in Japan (a seventh copy in Berlin was destroyed during World War II) – several new editions and numerous translations have been made throughout the centuries, and it was not replaced as "the" pharmaceutical materia medica of China until 1959: over 400 years after its first publication.
