Bonchoyuham Nyoryeong(本草類函要領) shows how Donguibogam(東醫寶鑑) -Mirror of Eastern Medicine- is understood, digested into Korean medicine, and at the same time how it participated in the historical shaping of Korean medicine since the publishing in the early 17th century. The author, Hyeon Jae-deok, internalized the structure, content, and significance of Donguibogam and drew out a novel, concise, but comprehensive type of medical manual, while many other medical books since the 17century in Korea are estimated to have been an abridged edition of the Donguibogam. It may well be estimated as exemplar of the extent to which Donguibogam informed Korean medicine since the 17 century. The book shows as well how Bencao Gangmu(本草綱目) -Compendium of Materia Medica- and Donguibogam are merged and set a new medical stream in the 19th century Korea. Hyeon Jae-deok looked at the Bencao Gangmu from the lens of clinical treatment and prescription such that he focused on sections, elements, or parts of procedures, treatments, and prescriptions, not on the herbal taxonomic knowledge of the book. This perspective was embodied in Bonchoyuham(本草類函), which cited simple remedies, prescriptions, or treatments from Bencao Gangmu.
