How to get rid of nasal congestion?

I don't have a cold, but my sinuses have always been a little congested. I heard if you eat horseradish often, it will help clear your nasal pages, but i hate the taste. Anything else that could clear my nasal pages? ( I also have a lot of mucus in my throat, anything to break that up and easily cough it up ) I would prefer, not to take medicine or get surgery.
