Rhinitis 19 Sources: https://www.ncbi.nlm.nih.gov/pubmed/26539289	Primary		Approved 8583	Spray-Tish Approved Use Spray-Tish is a nasal decongestant. It works by clearing a stuffy or blocked nose by shrinking the inflamed and swollen blood vessels in the lining of the nose. Spray-Tish relieves a stuffy or blocked nose (nasal congestion) associated with the common cold, hayfever and rhinitis. A runny nose, nasal congestion, itching and sneezing, are typical symptoms of a condition known as rhinitis.
