Project period

2006 – 2011

An unexpected result of an earlier randomized controlled trial was that patients receiving Echinacea had fewer subsequent upper respiratory infections (URIs) during the four-month study period than children who received placebo for treatment of acute symptoms. This study is designed to further delineate the potential efficacy of Echinacea in preventing URIs in children.
