## Claims

### Claim 1

A system for rinsing a human nasal passage, the system comprising:
a mixture comprised of water, chlorine dioxide, unsaturated fatty acid, olfactory stimulant, fixative compound, and inorganic salt; and
an apparatus for dispensing 0.3 to 3 milliliters of the mixture into a nasal passage as a mist.

### Claim 2

A method of practicing nasal hygiene comprising the steps of applying to a person's nostril a mist of liquid nasal wash composition consisting essentially of the product of compounding under homogenizing conditions water, an amount of a source of chlorine dioxide sufficient to generate or provide 0.01% to 5% by weight of chlorine dioxide, 0.1 to 1% unsaturated fatty acid, 0.1 to 3% by weight of at least three olfactory stimulants; 0 to 5% by weight of at least one fixative compound; and 0.1 to 2.5% by weight of at least one inorganic salt, massaging the outside of the nostril, and blowing air out of the nostril.
