A collaboration with the University of Washington.

Purpose of Research
The proposed study is a randomized, double blind, placebo-controlled trial of echinacea for the treatment of upper respiratory infections (URIs) in children between the ages of two and 11. The aims of the project are to determine the following:

  1. Does echinacea shorten the duration and/or lessen the severity of URIs?
  2. Do children receiving echinacea for treatment of URIs have a reduced rate of secondary bacterial infections?
  3. Is the use of echinacea in patients between the ages of two and 11 associated with any significant side effects?

Research Objectives
A two-year-study of 600 children is planned. Not only will the results of this study determine if echinacea, the most popular medicinal herb sold in the United States, is an effective therapy for URIs in children, but the study will also provide a design framework for future assessments on the efficacy of complementary and alternative medicines in children.
