This study aimed to compare the therapeutic effects of fresh (CMF) and dried (CMD) Centipeda minima against allergic rhinitis (AR), elucidate their underlying molecular mechanisms, and identify the bioactive compounds responsible for their immunomodulatory actions. An ovalbumin-induced AR mouse model was treated with CMF or CMD extracts, followed by evaluation of nasal symptoms, serum biomarkers (IgE, histamine, cytokines), and nasal mucosa histopathology. Transcriptomics and widely targeted metabolomics were integrated with network pharmacology to identify differentially expressed genes and bioactive components, which were further validated in RAW264.7 and RBL-2H3 cells. CMF and CMD exhibited distinct anti-AR mechanisms: CMF predominantly suppressed Th2 responses (reducing IgE, IL-6, and histamine while elevating IL-10), whereas CMD enhanced Th1 activity (increasing IFN-γ). Metabolomic analysis revealed CMF was rich in amino acids while CMD contained higher flavonoids, with neocnidilide and 6-gingerol identified as key bioactive compounds that modulated TNF-α, IL-6, and IL-10 via NF-κB and JAK-STAT pathways. These findings demonstrate that CMF and CMD exert complementary anti-inflammatory effects through Th2 inhibition and Th1 activation, respectively, providing a molecular basis for the traditional use of Centipeda minima and highlighting its bioactive compounds as potential therapeutics for inflammatory diseases.
