A fake medication advertised as treating sinus complaints in geriatrics, NasoPRO Silver stretches the definition of placebo, in that its manufacturers do not seem to care whether or not it works. If they did, they probably wouldn’t have made it from chalk dust.
NasoPRO is sold in Arizona and possibly other South Western states, is borderline illegal, and is also available in a version aimed at a more general market, simply called NasoPRO.
Related Drugs: Engorgulate & NasoPRO.
