Effect of acupuncture on allergic rhinitis: clinical and laboratory evaluations.

Of 22 subjects with allergic rhinitis who received a series of 6 acupuncture treatments, 11 (50%) were virtually symptom-free by the end of the series, 8 (36%) experienced a moderate reduction in symptoms, and 3 (14%) received no significant relief. Clinical assessment of symptoms was made on a 6-point scale before the first treatment and before each subsequent session. Laboratory tests included absolute blood eosinophils, percentage of nasal eosinophils, and radioimmunoassay of serum IgE, performed before the first treatment, at the end of the series, and 2 months later. A significant decrease in subjective clinical rating of symptoms correlated with a concurrent drop in absolute numbers of blood eosinophils and percentage of nasal eosinophils. IgE levels decreased in 64% of the subjects by completion of treatment and in 76% at 2-month follow-up.
