Abstract
CLINICAL QUESTION: Are Echinacea products associated with a reduced incidence and a shorter duration of common colds compared with placebo? BOTTOM LINE: Individual prophylaxis trials show no association with prevention of the common cold, but exploratory meta-analysis suggests that Echinacea products may be associated with a small reduction in cold incidence. In treatment trials, there was no association of Echinacea products with a shorter duration of colds.Entities:
