allergic rhinitis
"I had a very nasty sinus infection and now have a pretty bad cold with Post Nasal Drip/Nasal Congestion . Using this daily as prescribed from my doctor has cut down on the nasal congestion, and the sore throat I'd had continuously because of the post nasal drip. Can't speak to it's effectiveness for allergies, but for cold/infection based congestion it's allowed me to sleep through the night."
