A pharmaceutical work in four volumes, written by Zhang Lu of the Qing Dynasty, published in 1695. It categorizes drugs into 32 sections based on the Bencao Gangmu: water, fire, earth, metal, stone, halide stone, mountain herbs, fragrant herbs, marsh herbs, poisonous herbs, vine herbs, aquatic herbs, stone herbs, moss herbs, grains, vegetables, fruits, tropical fruits, flavors, aromatic woods, tall trees, shrubs, parasitic woods, budded woods, hidden tools, insects, dragons and snakes, fish, shellfish, birds, beasts, and humans, collecting approximately 700 types of drugs. Each drug is first described in terms of its nature, flavor, origin, and processing of materia medica, followed by the original text from the Benjing. For drugs not mentioned in the Benjing, their therapeutic effects are directly explained, referred to as "inventions." It also includes various scholars' theories and attached prescriptions. The discussions contain many personal insights and experiential knowledge. Multiple Qing Dynasty editions, Japanese editions, and lithographic editions exist. After 1949, typeset editions were published.
