Objective To explore the clinical effect of treating allergic rhinitis (AR) with syndrome of Lung Qi Deficiency and Coldness by acupuncture at Dong's extraordinary points based on the theory of "the lung governs the skin and hair". Methods Prospectively, 62 patients with allergic rhinitis (AR) of Lung Qi Deficiency and Cold Syndrome were selected as the research subjects. All patients received treatment in our hospital from June 2023 to March 2025. The research subjects were evenly divided into a control group and a research group by the random number table method. The control group was treated with loratadine+mometasone furoate nasal spray, while the research group was treated with acupuncture at Dong's Extra Points+Yu Ping Feng San on the basis of the treatment for the control group. Both groups were treated for 14 days. The therapeutic effects, clinical symptoms before and after treatment, quality of life, serum inflammatory factors, and recurrence status after 12 months of follow-up were compared between the two groups. Results The total effective rate of treatment in the research group was higher than that in the control group (90.32% vs 64.52%, P<0.05). After 14 days of treatment, the traditional Chinese medicine syndrome scores, total nasal symptom score (TNSS), rhinoconjunctivitis quality of life questionnaire (RQLQ) scores, and C-reactive protein (CRP) levels of both groups decreased, and those in the research group were lower than those in the control group (P<0.05). After the end of the treatment course, the research subjects were followed up for 12 months. The recurrence rate of the research group at 6 months was lower than that of the control group (7.14% vs 30.00%, P<0.05). The cumlative recurrence rates at 6 and 12 month were significantly lower in the observation group than in the control group (P＜0.05). Conclusion Treating AR with syndrome of Lung Qi Deficiency and Coldness by acupuncture at Dong's Extraordinary Points can effectively improve the curative effect, relieve clinical symptoms, enhance the quality of life, and reduce the levels of serum inflammatory factors
