In allergic rhinitis patients with severe symptoms, control of severe allergic reactions is limited with saline nasal irrigation. Therefore, there have been several attempts to use saline nasal irrigation in combination with other treatments to treat allergic rhinitis. This study tries to explore the effect of nasal irrigation with Chinese herbal medicines on allergic rhinitis.
In this study, patients with allergic rhinitis over 20 years old were collected from the clinics of Otolaryngology and Traditional Chinese Medicine clinics. The subjects were randomly divided into two groups. They used the devices of NeiMed sinus rinse to irrigate the nose with 240 cc of Chinese herbal medicine solution or placebo each morning and evening for 2 months. Subjects in both groups filled questionnaires, and received acoustic rhinometry, rhinomanometry, and eustachian tube function tests before and after nasal irrigation. This study tries to explore the effect of nasal irrigation with Chinese herbal medicines on allergic rhinitis.
