Saline can be used to wash the nose for rhinitis, but it should be used under the guidance of a doctor and should not be used in excess. Rhinitis is a kind of inflammation of the nasal mucosa, which may be caused by long-term nose picking, viral infection, environmental pollution and other factors, and usually results in nasal congestion, runny nose and other uncomfortable symptoms. Patients with rhinitis can use saline to wash their noses in moderation, to flush out the stagnant inflammatory secretions, pathogenic microorganisms and allergens in the nasal cavity, to reduce the inflammatory response of the nasal cavity, to promote the recovery of the cilia function of the nasal mucous membrane, and to assist in the reconstruction of the nasal microenvironment, but generally will not achieve a healing effect. If the use of saline nose wash, the nasal mucosa congestion and other adverse reactions, should be promptly discontinued, and go to the regular hospital.
