Contents recorded in "Illustration of Materia Medica":

Materia Medica Illustrated Classic is a masterpiece of pharmacology and the most perfect and scientific medical work in Song Dynasty. The book inherits the ancient medical heritage of the motherland for more than 1000 years, supplements its own research experience and discoveries, draws a large number of drug graphics and explains them in words.

Accurately recorded the origin, shape, nature, use, collection season, refining method, identification method, compatibility, taboo and so on. All kinds of drugs, with illustrations and pictures, are accurate and convenient to use, which is the precedent of Compendium of Materia Medica by Li Shizhen, a famous medical scientist in Ming Dynasty.

Unfortunately, the feudal ruling class did not attach importance to scientific and technological inventions, which made this masterpiece disappear behind Su Song, and its content could only be scattered in the later generations' Materia Medica. Among them, Li Shizhen's Compendium of Materia Medica made many reservations and references, but failed to see the whole picture.
