A double-blind, randomized, placebo-controlled clinical study on Sinus Buster nasal spray was recently completed by leading researcher Dr. Jonathan Bernstein, a professor and immunology/allergy research specialist at the University of Cincinnati's College of Medicine, department of internal medicine, division of immunology/allergy. The study measured the improvement in nasal congestion, sinus pressure, and pain. It also evaluated speed of action and key safety parameters.
