This technique involves inhaling thermal waters, and is based on the same principles as spray, although in this case the size of the mineral-medicinal water droplets is much smaller, and the water is administered in a state immediately prior to vaporisation. The diminutive droplets of thermal water settle and bathe the upper respiratory passages, acting specifically on complaints of the throat, tonsils and pharynx.

Its use is particularly recommended in ailments of the upper respiratory passages, although they may also work satisfactorily in the middle and lower passages.
