PURICA Prevail is effective because it halts viral replication and increases the activity of immune cells that actively fight cold viruses. PURICA Prevail Cold & Fever has also been shown highly effective against Respiratory Synctial Virus (RSV)—a severe type of respiratory condition that affects the lungs and breathing passages.
Since the herbal ingredients contained in PURICA Prevail are antibacterial, they also help prevent bacterially-induced infections and complications often associated with viruses.
The research and methodology behind PURICA Prevail has been peer reviewed and accepted for publication in the prestigious Journal of Pharmaceutical and Biomedical Analysis.
Since PREVAIL Cold & Fever should be taken immediately on experiencing symptoms of the common cold, fever, cough or sore throat, for maximum efficacy, we recommend that you have the product on hand during cold & flu season.
