Spraying: history 

Since ancient times it was observed that the inhalation of air in which they were dispersed substances had a beneficial therapeutic effect for respiratory ailments. The doctors had noted that the breaking of waves on the rocks, in thousands of microscopic droplets, spread into the surrounding air, has therapeutic qualities. They did not know that was the active iodine content in marine and vaporized, but could see the benefits of the effects of inhalation on patients. 

Spraying, giving the opportunity to heal in a natural way, was then widely adopted by the ancient medicine. They then tried to use any natural sources of spraying and still is practiced inhaling sulphurous salsoiodica or at the spa. Indeed the history of inhalation therapy is closely related to the exploitation of spas where were spread the inhalation of balsamic vapors to breathe better. The archaeological and literary evidences have taught us that the use of thermal water was widespread in the Mediterranean since ancient times. The Greeks were among the first people to exploit and enjoy the hot springs which they attributed a supernatural significance for their beneficial effects. 

By virtue of the many benefits, in the following centuries the man tried to reproduce artificially the process of spraying:  a simple and effective technique is the suffimigi or fumenti . This is of inhalation of medicinal substances, pour in hot water, then breathing the steam with the head covered with a towel, or using pots with cover to funnel, or by applying on a lid of a pot made of cardboard funnel. The use of "suffumigi" was for centuries the technique more natural and more wise to inhale substances beneficial spread to every house and every social class. These rudimentary methods have resisted the time and are still in use.

In the twentieth century the German physicist Siegl produces the first steam inhaler: born aerosol spray or aerosol using rudimentary equipment in which air or oxygen is forced with a blower in a solution for Medicinally fragmented into small particles. 

But it is only in the second half of the twentieth century with the spread of electrical devices, it is put into marketing the first device for aerosol therapy for use at home. Since then, technological development has produced ever more efficient nebulisers, which sprays tiny particles that can penetrate to the bottom of the respiratory system also reaching the pulmonary alveoli. Today, the aerosol is the most simple and natural to treat diseases of the airways: the action is fast, intense, localized sull'organo ill and with reduced side effects.
