Traditional Chinese medicine (TCM) is the treasure of the Chinese nation. The quality of TCM has become an important factor restricting its development, and the modernization of drying technology is an important link in the development of TCM. The freeze-drying technology can keep the original form and the nutrients of the materials, and obtain the high-quality dry matter. This paper introduced the principle and development of freeze-drying technology, and summarized the research progress of freeze-drying technology in field of TCM, including the purpose of freeze-drying technology applied in the processing of TCM, the influencing factors, and the influence of freeze-drying on the tissue composition of TCM, so as to provide new ideas for the systematic research of freeze-drying of TCM.
