Hot vapour inhalation can give effective relief from coughs and colds, sinusitis, bronchitis and respiratory inflammation.
Inhalation of the hot, moist water vapour carries the aromatic and anti-inflammatory ingredients added to the preparations for inhalation.
The water vapour particle is sufficiently small to arrive directly in the inflamed alveolus and help liquefy the mucus, which is then expelled by coughing.
Water vapour, mixed with perfumed essences and aromatic oils, has been used since ancient times as an effective remedy to unblock the upper airways.
