The best natural nasal decongestant is a long steam inhalation session which lasts for about 20 minutes or so. You can add a few drops of eucalyptus oil to the water, which will help clear out your stuffy nose very quickly. Just make sure that you do not swallow back the mucus that runs down your throat, clear your nose and sniff it out instead. This will help to improve your situation. Another very good solution is to employ 'jal neeti', an ancient Ayurvedic method which basically advises you to rinse out your nose. Hold some warm water in the cup of your palm and inhale water hard. It should come out, along with mucus deposits, into your throat, and you should not swallow this water. Spit it out instead. This may take many attempts before you can actually get it right. It can also be quite a disgusting process to begin with, which may make you feel queasy due to the mucus coming in contact with your taste buds.
Another excellent method is to have a cool mist humidifier running in your home at all times. This will help to keep your sinuses clear and will keep your nose from being stuffy as well. Make it a point to clean the humidifier every other week, so that fungus does not take root there. You should also increase your water intake to about 10 litres a day. This will keep the liquids in your entire body flowing, thus making it easier for you.
