Abstract: According to the theory of traditional Chinese medicine, blood stasis is a main pathological mechanism in the development of vascular diseases. Supplementing Qi and activating blood circulation, as the therapeutic principle for the blood stasis, has been adapted. Studies demonstrated that the supplementing Qi and activating blood circulation recipe could regulate the expression of vasoactive peptides in vascular smooth muscle cells (VSMCs). The recipe inhibited the formation of neointima following arterial intimal lesions through down-regulating expression of proliferation-related genes and phenotypic modulation of VSMCs. The recipe also markedly inhibited the adhesion and migration of VSMCs and matrix remodelling by means of a mechanism that balances extracellular matrix turnover rate. The purpose of this review is to summarize the recent advances made in our understanding of new functions for the recipe in regulating VSMCs behaviours and their microenvironment relevant to vascular diseases and maintaining proper homeostasis.
