Saline nasal rinsing, i.e. physiologic saline nasal rinsing, causes few side effects, is easy to operate, and has a definite therapeutic effect, and is routinely and commonly used as a means of treating rhinitis. Saline nasal wash for rhinitis symptoms can play a role in relieving, but not to achieve the effect of causative treatment, should be identified after the type of rhinitis according to the doctor’s instructions at the same time for causative treatment. 1. For patients with acute rhinitis, using saline to wash the nasal cavity can effectively remove nasal secretions and pathogens, and saline has the effect of promoting the recovery of mucosal cilia; 2. For patients with allergic rhinitis, using saline to clean the nasal cavity can effectively reduce the concentration of allergens in the nasal cavity, reduce the stimulation of allergens on the nasal mucosa and sensitive nerves, thus relieving the symptoms of allergic rhinitis caused by itchy nose, sneezing and runny nose; 3. For patients with dry rhinitis or atrophic rhinitis, the stimulation of disease-causing factors will lead to repeated nasal dryness. Rinsing the nasal cavity with saline can increase the water content of the nasal mucosa, thus helping to relieve the symptoms of nasal dryness. For patients with rhinitis, it is recommended to follow the doctor’s instructions for standardized treatment.
