ABSTRACT
Evidence on the efficacy of standardised phytoterapic extracts for the prevention of recurrent respiratory tract infections (RRTIs) in children is reviewed. Echinacea extracts are widely used in European countries and in the United States as immune-stimulating agents. However, further prospective, appropriately powered clinical studies are required to confirm their benefits in reducing duration and severity of RRTIs.
