Acupuncture has been used for centuries to treat allergy symptoms such as nasal congestion, scratchy throat, puffy eyes and more. A multicenter randomized controlled trial conducted by researchers at the University Medical Center in Berlin assessed 422 people over the course of 2 months. The study concluded that acupuncture led to significant improvements in both quality of life and reduction of antihistamine use for allergy sufferers. Another study performed in 2018 concluded that acupuncture significantly reduced the number of days antihistamine was used while improving quality of life and seasonal allergic rhinitis symptoms.
