A sinus infection is typically caused by the common cold, allergies or nasal obstruction, according to MedlinePlus. Grapefruit seed extract has been used to treat various conditions because of its antioxidant and anti-inflammatory properties. Talk with you doctor before using grapefruit seed extract to treat sinusitis.


Sinus tissue is lined with mucus membranes that help to keep the nasal passages moist. When the soft tissue becomes irritated, it increases blood flow and mucus production. The swollen sinuses trap mucus in the nasal cavities, creating an environment -- warm, stagnate and moist -- for the growth of viruses, bacteria and fungi. The swollen sinus cavities block the normal drainage of discharge through the nostrils, placing excessive pressure in the head.


Sinus infection symptoms include nasal discharge, ear pain, sore throat, bad breath, fever, fatigue, post-nasal drip and sinus pressure pain, according to MayoClinic.com. Post-nasal drip is the constant dripping of excess mucus in the back of the throat that leads to coughing, throat irritation and bad breath. Sinus pressure pain might be felt in the teeth, behind the eyes, in the ears and in the forehead. Sinus headaches are a dull, throbbing pain that is typically worse when you wake up and improve throughout the day.
