How does Vicks inhaler work?

 *How it works* ⁉

Vicks inhaler contains menthol, camphor and pine needle oil, which have traditionally been used for many years as inhalations for their decongestant effect.
They give off vapours that have a cooling and decongestant effect in the lining of the nose when you breathe them in.

It opens the air passage of the nose and helps to breath smoothly.
