Hypotonic saline solution moisturizes the nasal cavity and softens and dissolves thick, crusty mucus, making it easier to remove. hypotonic saline intranasal is available over the counter (OTC) as a mist spray or a gel.
Hypotonic intranasal saline solution contains sodium chloride and potassium chloride salts that moisturize the nasal passage, and propylene glycol and polyethylene glycol, wetting agents that help even distribution of the saline solution.

Allergy (Allergies)
An allergy refers to a misguided reaction by our immune system in response to bodily contact with certain foreign substances. When these allergens come in contact with the body, it causes the immune system to develop an allergic reaction in people who are allergic to it. It is estimated that 50 million North Americans are affected by allergic conditions. The parts of the body that are prone to react to allergies include the eyes, nose, lungs, skin, and stomach. Common allergic disorders include hay fever, asthma, allergic eyes, allergic eczema, hives, and allergic shock.
