The Rhinotherm, a new, very expensive device being hyped for relief from common colds, failed in a recent study to either inhibit or kill the rhinoviruses responsible for common colds, researchers at the University of Virginia Health Sciences Center and the Cleveland Clinic Foundation have reported.
The Rhinotherm costs about $1,000 and is available by prescription only. Like other devices new on the market, the Rhino-therm claims to offer a "breakthrough" treatment that outsmarts cold viruses by shooting hot, humid and sometimes medicated air at or up your nose.These are hand-held devices rather than humidifiers.
After using the Rhinotherm, 68 cold sufferers who volunteered for the Cleveland study reported no relief at all from the most basic symptoms of stuffiness and congestion.
Less expensive variations of this product include the Viralizer and Bernhard Steam, which cost about $50.
