Traditional Chinese medicine(TCM) is a complex system, featured with integrity and characteristics. Structural component TCM is a well-organized integrity of traditional Chinese medicine, reflecting multi-component integration effect of TCM. It gives us a new view on the material basis of TCM. Currently, conventional researching strategies are not enough to deal with the relationship between material basis and efficacy, multi-composition, multi-targets, and multi-section mechanism. Post-genome area gives a birth to bioinformatics, which involves systematic biology, different levels of omics, corresponding mathematics and computer techniques. It increasingly becomes a powerful tool to understand complicated system and life essential laws. Research ideas, methods. and knowledge of data mining technology of bioinformatics combined with the theory of structural components of Chinese medicine bring a new opportunity for developing structural components of Chinese medicine, systematically exploring the essence of TCM and promoting the modernization of TCM.
