To describe the construction and application of clinical evidence database of traditional Chinese medicine (TCM-CED) so as to provide evidence for TCM research. The construction process primarily includes: expert team building, TCM-CED function module design, evidence collection and quality control. The applications of TCM-CED primarily include the following aspects: automatic generation of systematic review/meta-analysis in TCM, automatic generation of evidence reports on dominant diseases of TCM, automatic generation of evidence index of Chinese patent medicine, optimizing the selection of outcomes in TCM research, tracking methodological and reporting quality of TCM research, and promoting international dissemination of TCM evidence. With the rapid development of information technology and artificial intelligence, TCM-CED will be combined with artificial intelligence to achieve the construction of all-dimensional TCM evidence chain and the automation of the whole process.
