Salt water is the best home remedy for alleviating the irritation that accompanies a runny nose. Salt water will help thin the mucus, making it easier and more comfortable to expel. It will also help clear the nasal passages of irritants.
Mix one-half teaspoon of table salt in two cups of distilled warm water. Using a dropper, put a few drops of the solution into each nostril with your head tilted back. Inhale very gently to draw the solution further into your nasal passages. Then blow your nose to remove excess mucus and solution. Do this a few times at a sitting until you feel relief. Repeat a couple of times each day until your condition improves.
Steam is also an effective home remedy for a runny nose. It helps clear out excess mucus that causes a runny nose and sneezing.
Hold your face over a bowl of hot water, with a towel over your head to trap the steam. Breathe in the steam for about 10 minutes, and then blow your nose. Do this three or four times a day. You can also add a few drops of eucalyptus oil or menthol to the hot water before breathing in the steam. Alternatively, you can take a hot shower or bath.
Mustard oil has antibiotic, antiviral and antihistamine properties that can provide instant relief from various symptoms of a runny nose.
Heat a small amount of mustard oil until it is slightly warm. Using a dropper, put one or two drops of the oil in each nostril. This will help clear up the nasal passages. Do this two or three times a day. Add two to three tablespoons of mustard oil and one tablespoon of caraway seeds to a pot of boiling water. Inhale the steam. The strong aroma of mustard oil will warm up the respiratory system, thus providing instant relief from a runny nose. Do this twice daily.
