Sinusitis is inflammation of the sinuses. This occurs as a result of a build up of bacteria after a cold or from allergies or some sinus irritant. Sinus infections can last for a short period of time or re-occur and become chronic. (1) If it is a chronic sinus infection you are looking to remedy there are a variety of roads to go down. Not much research has been done in this area, so unfortunately there is little evidence that these options can help, but they are worth a try.
Doing a saline nasal wash is a great way to break up some of the mucus and get some air flowing through your sinuses. It requires the saline wash and a device to get it into your nose. A neti pot, nasal bulb or squeeze bottle will do the trick. I actually use a neti pot and love it, take my advice and do it in the shower, because it does get messy. These devices can be bought at the store and you can either buy the saline wash or mix your own: (1)
Saline wash mixture
3 teaspoons iodine free salt
1 teaspoon baking soda
1 cup warm distilled or boiled water (if you boil it let it cool before using)
Allergens and Anti-Inflammatory Diet
Allergens in your diet could also be contributing to inflammation in your sinuses. Cutting out the foods that are allergens from your diet may yield a reduction in inflammation, the common allergens are: eggs, wheat, dairy, seafood, soy, peanuts and tree nuts. Just because a person may be allergic to one food does not mean they are allergic to others. Many people determine allergens or food sensitivities through an elimination diet; a dietitian can help navigate the process.
Although there is not much research in this area, another option some have claimed to benefit from introducing more anti-inflammatory foods into their diet, such as: green tea, ginger, garlic, thyme, oregano, rosemary and berries. (2) Inflammation is at the root of sinus infections, thus theoretically if these foods are proven to reduce inflammation, you may see some relief.
