"Despite a large body of information concerning the use of Echinacea, the clinical efficacy of various preparations of Echinacea has not been proven in rigorous randomized blinded trials. We found that during 8 weeks of follow-up, treatment with fluid extract of Echinacea purpurea did not decrease the incidence or severity of colds and respiratory infections as compared to placebo. Although side effects were usually mild and transient in our study, life-threatening allergic reactions have been observed in rare cases even after oral administration of Echinacea extracts (35). Therefore, the drug commission of the German physicians recommend against the use of Echinacea extracts as immunostimulating agents until their clinical efficacy is demonstrated in appropriate designed trials (35)."
