Li Shizhen (1518—1593) is a famous medical scientist. He is mainly known for spending most of his life on a very long book of natural medicine called Bencao Gangmu. The book is highly detailed and organized, and it is the product of several years’ study of many books and medical texts. It summed up the previous medical knowledge and experience, and corrected mistakes, lifting the Chinese medicine science to a new level. He added his own understanding based on his medical practice and his family’s medical knowledge. It is considered as the greatest scientific achievement of the Ming Dynasty.

Both his father and grandfather were doctors and he grew up helping his father in his practice. When he was 38, he cured the son of a Chu prince, and a few years later, he was invited to be an official. During this period, he read many old medical texts. Meanwhile, he found there was some incorrect information. Besides, the naming and categorization(分类) of the herbs were in a mess. So he wanted to survey all the knowledge of his time and write the most correct natural medical text.

________ He collected and referred to(参考) about 800 medical books. He travelled around to get first-hand experience. He also interviewed experts in each area, found people who worked with wild plants and animals and made communications with them. After many years’ efforts, the first draft(手稿) was completed.
