Nasal inflammation saline. good?

Absolutely: One function of the nose is to trap large particles from getting into the lung. Saline irrigation of the nose restores humidity, helps clear thick secretions and crusting, also removes pollen and other substances that stick to the lining of the nose.

Yes and no: Nasal saline rinses don't address the inflammation in the nose and sinuses directly, but remove the inflammatory gunk (for lack of a better word) that is secreted by the linings of the nose and sinuses in chronic sinusitis, infectious sinusitis, and allergic rhinitis. Most people with chronic or recurrent inflammation in the nose or sinuses find saline rinses to be very helpful to them.
