Using a saline solution to rinse the nasal passages can help clear mucus and reduce inflammation. You can use a neti pot or a saline nasal spray. Make sure to use distilled or sterile water for the solution.
Inhaling steam can help moisturize the nasal passages, reduce congestion, and provide relief. Boil water, pour it into a bowl, lean over it, and cover your head with a towel to trap the steam. Breathe in deeply.
Applying a warm compress over your sinus areas (forehead, nose, and cheeks) can help relieve pain and pressure.
Mixing a tablespoon of raw, unfiltered apple cider vinegar in a cup of warm water with honey to taste, and drinking it a few times a day, may help with sinusitis symptoms.
Add a teaspoon of black pepper powder to a bowl of soup and drink it slowly. Do this two-three times a day for a week. Consuming black pepper will reduce sinus inflammation and the mucus will dry up.
