The stability and controllability of the quality of Chinese medicinal materials are directly related to the sustainable development of Chinese medicine industry. The construction of a traceability system covering the whole life cycle of Chinese medicinal materials has become a key measure for national policy guidance and industry upgrading. This paper expounds the policy background and practical necessity of the construction of the traceability system of Chinese medicinal materials, and systematically analyzes the key nodes covered by the whole life cycle of Chinese medicinal materials, it also systematically analyzes the integrated application of modern information technologies such as blockchain, internet of things, and big data supported for the traceability system. Practice shows that the effective application of the traceability system can significantly improve the transparency and supervision efficiency of the quality of traditional Chinese medicine and enhance consumer trust. However, the current system construction still faces many difficulties, including the lack of standardization of indicators, the lack of technical maturity in some links, and the problems of data reliability and privacy security. The purpose of this study is to provide theoretical reference and practical direction for the further improvement of the traceability system of Chinese medicinal materials. It is suggested that in the future, taking domestic bulk medicinal materials as a breakthrough point, reducing costs through technical integration, improving policies and regulations, and finally realizing the whole variety traceability network of “source can be traced, whereabouts can be traced, and responsibilities can be investigated”, so as to promote the high-quality development of the industry.
