Gustatory rhinitis is a type of nonallergic rhinitis, which is an inflammation of the nose's mucous membrane, states the American Family Physician. Those with nonallergic rhinitis experience congestion, sneezing and postnasal drip, symptoms normally associated with allergies, according to Mayo Clinic. However, instead of being caused by allergies, nonallergic rhinitis has no known cause and usually manifests in older adults.

Gustatory and nonallergic rhinitis has no known cure, but it is treatable by home remedies or prescription medications, advises Mayo Clinic. Over-the-counter saline nasal sprays, prescription corticosteroid or antihistamine nasal sprays, and decongestants can all help to treat the symptoms. A dripping nose when eating is treatable with anti-drip anticholinergic nasal spray that helps to reduce the running. Rinsing out the nasal passages and blowing the nose can also help to reduce nonallergic rhinitis. Rinsing out the nose requires a long-tipped squeeze bottle and distilled water.
