From a western clinical standpoint, allergic rhinitis is an IgE‑mediated inflammatory disease of the nasal mucosa driven by allergen exposure and characterized by sneezing, itching, rhinorrhea, and congestion. Standard care prioritizes intranasal corticosteroids, non‑sedating antihistamines, leukotriene modifiers in selected cases, and allergen immunotherapy for persistent or severe disease. Against this background, acupuncture has been evaluated as an adjunctive therapy. Randomized trials—particularly larger seasonal studies—demonstrate that acupuncture can produce small-to-moderate reductions in composite nasal symptom scores and improvements in disease-specific quality of life compared with minimal/sham acupuncture or waitlist controls. Some trials also report less rescue medication use during active treatment blocks. These benefits often emerge within several sessions and may persist throughout a pollen season when treatments are continued, though durability beyond the treated season is less certain. Methodologically, study heterogeneity is substantial: point prescriptions vary, as do treatment frequency and total number of sessions. Sham controls range from superficial needling to nonacupoint insertion, each carrying a risk of physiologic effects that may dilute between‑group differences. As a result, pooled estimates likely represent conservative effect sizes. Expectancy and practitioner‑patient interaction contribute to outcomes, but mechanistic investigations suggest specific biologic actions as well—modest shifts in cytokine profiles (e.g., lower IL‑4/IL‑5, higher IL‑10 or IFN‑γ in some studies), potential effects on total IgE, and autonomic modulation of nasal vasculature and glandular secretion. Safety data are reassuring: most adverse events are minor and transient (bruising, soreness, lightheadedness), with serious events exceedingly rare under trained practitioners. In practice, clinicians may consider acupuncture for patients with persistent symptoms despite medications, those wishing to reduce drug burden, or patients preferring integrative approaches, ensuring it complements guideline‑directed allergy management and that red flags (e.g., uncontrolled asthma, recurrent sinusitis) prompt specialist evaluation.
