Nasal Douche

“Douche” is a French word, meaning to wash or soak.  Nasal douches have been around for a long time, allowing people to cleanse the nose of mucus and other debris like air-borne pollutants.  

The douche solution is made up of pharmaceutical grade salt and pure water and warmed to about body temperature (37˚C). The wash is then rinsed through the nasal cavity whilst the head is tilted to one side.

Rinsing the nasal cavity treats sinus symptoms and helps to keep the nasal passages moist.
The solution used in nasal douches must be sterile to avoid sinus infections. In more recent times, nasal douching with unboiled or unsterilized water infected with Naegleria fowleri, a microbial protist, has resulted in several cases of fatal brain infections (1).

In the Iglodine nasal douche, the nasal rinse would have been poured into the ceramic cup. The bulb would have then been placed inside the nostril and the rinse administered up through the central tube. “Iglodine” is an antiseptic from earlier times, which may have been used in this style of nasal douche.
