One natural and effective way to get rid of excessive phlegm or mucus at home is through nasal irrigation, according to WebMD. This procedure involves shooting a saltwater solution up a single nostril to loosen and flush mucus, bacteria and allergens out of the other nostril.
A bulb syringe, neti pot or squeeze bottle are suitable for performing nasal irrigation, explains WebMD. It's important to use distilled, previously boiled or sterilized water to make the solution, and the irrigation device should be cleaned after each use. Adults and children can safely use nasal irrigation to flush and moisturize the nasal cavity, as the procedure has no known adverse effects, according to the National Institutes of Health. However, WebMD advises against performing this procedure too often, as it has the potential to wash away protective substances that can prevent illness.
Other methods of treating excessive mucus at home include using a vaporizer and taking a steamy shower, as these solutions increase the amount of moisture in the home and help to soothe the throat, explains MedlinePlus. Drinking plenty of water can also provide relief, since liquids help to thin the throat lining, which makes it easier to cough up phlegm. Individuals should seek medical attention if the mucus buildup leads to shortness of breath and breathing difficulties or if the mucus is thick and has a greenish-yellow color.
