"There are three precious treasures in Northeastern China, namely ginseng, mink, and Ula grass." Most Chinese, whether in China or overseas, have heard this common proverb. In addition, if we were to frequent a Chinese herbal-medicine pharmacy or supermarket, we could easily purchase ginseng, which has long been prized as a valuable commodity in China. However, we actually know little about the complicated history of this root vegetable, including the production and consumption of ginseng in Chinese history. In The Empire of Ginseng, Chu-Shan Chiang offers a groundbreaking perspective on ginseng research by exploring how Qing China established practices for picking, collecting, and trading ginseng and how people consumed ginseng, specifically in the Lower Yangtze River region.
