Natural Nasal Sprays
Saline sprays are also common and are typically unmedicated. A mist of saline solution is delivered to help moisturize dry or irritated nostrils. See also nasal irrigation. They can also relieve nasal congestion and remove airborne irritants such as pollen, dust etc. thereby providing sinus allergy relief. The solution can be either isotonic or hypertonic. Isotonic solutions have the same salt concentration as the human body whereas hypertonic solutions have a higher salt content. Hypertonic solutions may be more useful at drawing moisture from the mucus membrane and relieving nasal congestion.
Nasal salves have been shown to alleviate respiratory discomfort caused by the increased dryness of air in pressurized air flight and some air conditioned offices (sick building syndrome) They have been shown to reduce susceptibility to various flight related respiratory infections.
Some patients with rhinitis find nasal sprays including plant-derived chemical complexes such as Ginger, capsaicin and tea-tree useful. There is however, no trial-verified evidence that they have a measurable effect on symptoms.

Famous quotes containing the word natural:
“The problem of the novelist who wishes to write about a man’s encounter with God is how he shall make the experience—which is both natural and supernatural—understandable, and credible, to his reader. In any age this would be a problem, but in our own, it is a well- nigh insurmountable one. Today’s audience is one in which religious feeling has become, if not atrophied, at least vaporous and sentimental.”
—Flannery O’Connor (1925–1964)
