Book excerpt: Volume V in the Ben cao gang mu series offers a complete translation of chapters 18 through 25, devoted to creeping herbs, water herbs, herbs growing on stones, mosses, and cereals. The Ben cao gang mu is a sixteenth-century Chinese encyclopedia of medical matter and natural history by Li Shizhen (1518–1593). The culmination of a sixteen-hundred-year history of Chinese medical and pharmaceutical literature, it is considered the most important and comprehensive book ever written in the history of Chinese medicine and remains an invaluable resource for researchers and practitioners. This nine-volume series reveals an almost two-millennia-long panorama of wide-ranging observations and sophisticated interpretations, ingenious manipulations, and practical applications of natural substances for the benefit of human health. Paul U. Unschuld's annotated translation of the Ben cao gang mu, presented here with the original Chinese text, opens a rare window into viewing the people and culture of China's past.
