The ingredients found in homemade sinus rinse solution recipes are distilled or boiled water, baking soda and salt that does not contain iodine. These rinses are made with typical items found in nearly every home.
One basic recipe entails the combination of about 2 teaspoons of salt, such as pickling salt without iodine, 1/4 teaspoon of baking soda and 1 liter (33.8 ounces) of sterile water stored in a clean container, notes the American Rhinologic Society.
Homemade nasal rinse solutions are natural methods to relieve rhinitis, chronic sinus conditions and infections, as noted by the American Academy of Allergy Asthma & Immunology (AAAAI). The AAAAI also provides another saline rinse recipe that involves the same ingredients, in different amounts. For this recipe, combine 3 teaspoons of salt (no iodine) with 1 teaspoon of baking soda. Store the mixture in a clean container. Then, add 1 teaspoon of this mixture to 8 ounces of distilled or boiled water. Add more sterile water if the rinse is too strong, according to AAAAI. Use a Neti pot, bulb syringe or other nasal rinse product.
Although nasal irrigation with a homemade saline rinse is useful for sinus problems, there are precautions required with nasal irrigation. To avoid any possible infections due to contaminated water, the water must be sterile or distilled, notes the United States Food and Drug Administration. If using tap water, then it is necessary to boil it for at least 5 minutes. Similarly, the boiled water must be kept in a clean and sealed container and used within a 24-hour period.
