Chinese Materia Medica, a rich tradition spanning thousands of years, encompasses plant, animal, and mineral sources. Key works like "Shen Nong"s Classic of Materia Medica" and "Compendium of Materia Medica" by Li Shizhen contributed to the development of a comprehensive theory, detailing collection, processing, properties, and usage. Notable milestones include the refinement of processing techniques and the classification of medicines based on their therapeutic effects and properties.
