Health care: Can saline nasal washing relieve rhinitis?
On the one hand, physiological saline can moisten and clean the nasal cavity, on the other hand, it can reduce the inhalation of allergens, thus helping to relieve the symptoms of nasal dryness and playing a certain therapeutic role in allergic rhinitis. But it has little effect on hypertrophic rhinitis, atrophic rhinitis and vasomotor rhinitis, and is basically ineffective in treating nasal septum deviation.
