Plant-derived immunomodulators are increasingly investigated as complementary strategies for managing chronic inflammatory disorders characterized by dysregulated innate and adaptive immune responses. This research evaluates the immunopharmacological effects of a standardized plant-based extract using integrated analyses of inflammatory biomarkers and cellular responses. In vitro assays were conducted in lipopolysaccharide-stimulated macrophages and activated T lymphocytes to assess cytokine modulation, nitric oxide production, and redox balance. Parallel ex vivo analyses examined peripheral blood mononuclear cells to determine effects on cell viability, proliferation, and phenotypic activation. The extract significantly attenuated pro-inflammatory mediators, including tumor necrosis factor-α, interleukin-6, and cyclooxygenase-2, while enhancing anti-inflammatory cytokines and antioxidant defenses. Mechanistic evaluations indicated suppression of nuclear factor-κB signaling, reduced mitogen-activated protein kinase phosphorylation, and modulation of intracellular calcium dynamics. Cellular assays further demonstrated normalization of macrophage polarization and restrained T-cell hyperactivation without cytotoxicity. Biomarker correlations supported dose-dependent immunomodulation with preserved cellular homeostasis. Collectively, these findings provide evidence that the plant-based extract exerts balanced immunopharmacological actions by dampening excessive inflammatory signaling while maintaining immune competence. The results underscore the relevance of biomarker-guided evaluation to elucidate mechanisms of plant-derived therapeutics and to support rational development for inflammatory conditions. This work contributes experimental support for plant-based immunomodulators as candidates for adjunctive management of chronic inflammation and immune-mediated pathologies. Importantly, translational relevance was strengthened by consistency across models, reproducibility across concentrations, and alignment between molecular endpoints and functional outcomes observed during experimentation, supporting robustness. Together, these data emphasize the therapeutic plausibility of standardized botanicals, inform dose selection, and justify future in vivo validation and controlled clinical exploration within integrative immunopharmacology frameworks. Such approaches may facilitate safer adjuncts, reduce reliance on broad immunosuppression, and advance evidence-based incorporation of plant medicines into contemporary inflammatory care paradigms guided by biomarkers and cellular readouts with translational precision and clinical relevance for diverse patient populations globally.
