The article focuses on a randomized, double-blind, placebo-controlled clinical trial, that was conducted to evaluate the ability of Echinacea purpurea to prevent infection with rhinovirus type 39 (RV-39). The results of the study suggested that echinacea was not effective for preventing rhinovirus infection as defined by laboratory criteria. Among those who were infected and receiving echinacea, there was a trend toward reduction in the number of clinical colds, compared with those who were infected and received placebo.
