Nasal congestion can be caused by many things: Allergies, cold and flu all play a major role. Whatever the underlying cause of nasal congestion, when you're suffering from it, you want quick relief. There are a few home remedies you can use to quickly remove nasal congestion. Unless you get rid of the originating cause, however, your relief will only be temporary. Some of these methods can be used on the go, while others are best suited for when you are at home.
Boil 2 cups of water and place into a glass bows. Add 8 drops of eucalyptus oil. Place your face over the bowl, then drape a towel over your head and the bowl, creating a tent. Inhale the vapours for 5 to 10 minutes. Try to breathe this in only through your nose, as that is the only way it will affect nasal passages. As you feel the congestion loosening, blow your nose to clear it. (Any brand of eucalyptus oil will do.)
Repeat the above process with tea tree oil or oil of oregano if you did not have results with eucalyptus oil. (Any brand of essential oils will do.)
Put 236ml. of warm water in a glass container. Add 1 tbsp of apple cider vinegar and a pinch of salt. Shake the container to mix well. Tilt your head back. Using an eyedropper or the tips of your fingers, drip the mixture into each nostril. Breathe deeply, keeping your head back. When you taste the mixture in the back of your throat, your nose will soon clear. Blow out.
Rub a small amount of vapour rub under the nostrils. This is the type you rub on your chest for chest congestion. Any brand will do, as they all have mentholyptus in them. Rub under the nostrils as needed; this will open nasal passages temporarily.
Peel a garlic clove and slice it thinly. Place a slice in each nostril and sit and relax for 15 minutes. The natural garlic oil will open nasal passages and kill bacteria.
Eat some hot salsa or cayenne pepper. If you don't have the stomach for eating a teaspoon of hot salsa, hot sauce or cayenne pepper straight, sprinkle it on some chicken or cheese, or in soup, or in anything you have to in order to ingest it. Hot peppers like cayenne contain an ingredient called capsaicin, which works like guaifenesin. Guaifenesin is in many over-the-counter cold remedies. Hot peppers, however, work much faster, and have the added benefit of boosting the immune system.
Cough drops with mentholyptus will work quickly also, but many have added sugar; so if you are a diabetic, use with caution. Avoid milk and dairy products when dealing with nasal congestion, as they cause more mucous.
If you suffer from recurrent nasal congestion, see your doctor to determine if you may be suffering from sinus infection and are in need of antibiotics.
