Hydrological indications in the therapy of pharyngitis

Pharyngitis is an inflammatory disease of the mucosal and submucosal structures of the throat. Infection may or may not be a component of the disease. Pharyngitis is one of the common illness for which patients visit primary care physicians. Most of them are diagnosed by clinical evaluation and usually respond to treatment with antibiotics, but exceptions occur when pharyngitis is caused by non bacterial inflammatory processes like virus, mycoses, reflux of gastric juices, tobacco or alcohol abuse. In these cases, as alternative and preventive, could be indicated the thermal therapy. For many centuries thermal waters have been used in the treatment of chronic inflammations of the upper respiratory airway, such as pharyngitis, with good results. Different thermal waters are currently used, in particular sulphurous or sulphurous- salty- bromic-iodic or sulphurous-sulfate-bicarbonate-carbonate alkaline or sulphurous-arsenical-ferruginous, normally utilized by inhalation or irrigation or aerosoltherapy. The principal pharmacological activity of these waters is connected to the concentrations of H2S, halogenates (Iodine e Bromine), sulfates, arsenic and the level of radioactivity, concerning their antimicrobial power and the mucolitic effect of sulphur.
