Wind-heat pathogen toxin dispersion

Wind-heat pathogen toxin dispersion is a therapeutic principle in Traditional Chinese Medicine (TCM) rather than a specific molecular target like a receptor or enzyme. It refers to the pharmacological action of clearing exogenous Wind-heat pathogens, which typically manifest as acute respiratory infections, fever, and inflammation (Yang et al., 2020). This principle is central to the use of herbal formulas such as Lianhua Qingwen and Yin Qiao San, which are employed to treat conditions like influenza and COVID-19 (Hu et al., 2021). From a modern biomedical perspective, this action involves a multi-target approach including the inhibition of viral entry and replication, the suppression of pro-inflammatory cytokines such as IL-6 and TNF-alpha, and the modulation of the host immune system (Runfeng et al., 2020). Because it describes a broad physiological effect achieved through complex mixtures of phytochemicals, it is considered an incorrect entry for a specific molecular target in a drug discovery context. Research indicates that the components of these formulas may interact with various proteins such as the SARS-CoV-2 main protease (3CLpro) or TLR4, but the term itself remains a clinical descriptor of TCM efficacy rather than a single biological entity.
