Pathogenic heat elimination

Pathogenic heat elimination is a therapeutic concept derived from Traditional Chinese Medicine (TCM) rather than a specific molecular target, receptor, or enzyme in the context of modern molecular biology. It refers to the pharmacological strategy of neutralizing 'pathogenic heat' (Re), a pathological state characterized by clinical symptoms such as high fever, inflammation, thirst, and localized redness (Journal of Ethnopharmacology, 2017). In modern pharmacological terms, agents that perform pathogenic heat elimination—primarily phytochemicals from TCM herbs—exert polypharmacological effects by modulating various inflammatory pathways and immune responses. These substances often function by inhibiting the production of pro-inflammatory mediators like tumor necrosis factor-alpha (TNF-α) and interleukins, as well as reducing the synthesis of prostaglandins by targeting enzymes like COX-2 (Biomedicine & Pharmacotherapy, 2019). Because it represents a broad physiological outcome resulting from multi-target interactions, pathogenic heat elimination cannot be localized to a single protein or biological molecule. Consequently, it is categorized as a pharmacological action or therapeutic category rather than a discrete drug target.

Pathogenic heat elimination is achieved through the inhibition of pro-inflammatory cytokines (e.g., TNF-alpha, IL-1 beta, IL-6), reduction of cyclooxygenase-2 (COX-2) activity, and modulation of the hypothalamus-pituitary-adrenal axis to regulate body temperature (PubMed: 28214333; PMC: 5313431).
