Horseradish - "The Stingnose"!

Horseradish is a natural decongestant.  Hold a spoonful of grated horseradish (the root) away (4 inches atleast) from your nose, take a deep sniff (be careful) and then put a small pinch on your tongue. If you can try this, you will be breathing easier within seconds of the sniff.

Decongestant Tea

Make a standard tea with thyme, ground ivy and hyssop. Drink at the onset of a cold or if you are congested. These herb contain volatile oils that clear nose, throat, and chest. The thyme helps eliminate sticky mucus and combine well with ground ivy and hyssop to relieve congestion.
