Dispelling blood stasis

Dispelling blood stasis (known as Huoxue Huayu) is a traditional Chinese medicine (TCM) therapeutic principle rather than a single molecular target such as a specific protein or receptor. This pharmacological category describes agents and strategies used to improve microcirculation, reduce blood viscosity, and resolve pathological hematological obstructions [1]. In a modern biomedical context, the effects of 'stasis-dispelling' agents are mediated through diverse molecular targets including cyclooxygenase-1 (COX-1), thrombin, and various cell adhesion molecules [2]. These agents are primarily utilized in the management of cardiovascular and cerebrovascular diseases, where they help prevent thrombus formation and protect vascular endothelial function [3]. Active compounds found in herbs like Salvia miltiorrhiza and Ligusticum wallichii, such as tanshinones and ferulic acid, demonstrate potent antiplatelet and anti-inflammatory properties [4]. While clinically effective for circulatory disorders, the lack of a single defined target makes drug-drug interactions, particularly with Western anticoagulants, a significant safety consideration [5].
