"Compendium of Materia Medica" is a masterpiece of popular herbal medicine with far-reaching influence. In order to solve the problem that previous works on herbal medicine were "voluminous and difficult to read", Wang Ang cut out the complex and simplified it, and selected more than 400 commonly used clinical medicines to compile this book. Under each medicine, the distribution of nature and taste, functions and indications, and key points of clinical application are all available. The text is simple, the formula is easy to remember, and there are clear diagrams. It perfectly combines practicality and theory, and is like a "Drug Quick Reference Manual" and "Medication Guide" tailor-made for clinicians, which greatly facilitates learning and clinical application. It has been widely circulated since the Qing Dynasty and has become one of the classic reading materials necessary for entry into TCM and clinical practice.
