One home remedy for nasal discharge involves mixing a cup of warm water, a pinch of baking soda and a teaspoon of salt, and squirting the solution into each nostril with a nasal syringe, states HowStuffWorks. If a syringe is not available, snort the solution from the hand.
After the solution enters the nasal passage, it is important to tilt the head up, down and to each side for 10 seconds each, notes HowStuffWorks. This ensures all four sinus cavities are saturated. After tilting the head each way, blow the nose. Drinking at least 8 ounces of water each day keeps mucus thin and the body hydrated, which helps to stop postnasal drip.
Using a humidifier to add moisture to the air may help with nasal discharge, according to WebMD. Some people may get relief by irrigating the nasal passageway with a neti pot or nasal spray. Nasal discharge is sometimes experienced because of allergies. To reduce allergies, dust and vacuum the home on a regular basis. Washing all sheets and blankets in hot water and covering them with dust mite-proof covers can help. Propping pillows up at night during sleep may prevent mucus from getting backed up in the throat as this can lead to nasal discharge.
