Seasonality of Cytokines in Inflammatory Disease: Exploring Molecular Parallels with the Yellow Emperor's Inner Canon.

Inflammatory cytokines are well-established drivers of organ-specific pathology, yet their seasonal patterning remains poorly integrated into a single explanatory framework. This review examines whether classical descriptions of Bi syndrome in the Yellow Emperor's Inner Canon (YEIC), translated using previously proposed molecular correspondences (Cold/IL-1, Dampness/IL-6, Wind/NF-κB, Evil/LPS) and treated here as a working hypothesis, are consistent with the contemporary biomedical literature. For each YEIC season-tissue pairing, relevant evidence was retrieved from PubMed covering seasonal disease epidemiology, cytokine mechanisms, and clinical progression; correspondence with the YEIC's descriptions was assessed qualitatively across five seasonal domains rather than through a literature review with predefined inclusion criteria. IL-1, IL-6, and NF-κB predominance was mapped thematically onto seasonal cycles of tissue involvement-bone (winter), tendons (spring), vasculature (summer), muscle (late summer), and skin (autumn)-with proposed progression to related visceral injuries. This correspondence is imperfect in at least one domain: cardiovascular disease shows a larger winter, rather than summer, peak in the broader literature, and the framework has not been tested against competing explanations such as temperature, vitamin D status, infection cycles, or behavior. These findings suggest, without establishing, that IL-1, IL-6, and NF-κB may offer a shared explanatory thread across conditions conventionally treated as etiologically distinct. The YEIC, reinterpreted through a molecular lens, offers a hypothesis-generating model requiring prospective, comparative validation.
