I review studies in my Galen's Watch Report but only report on human ones. I thought this study was of interest but, as it is not human, I could not review for Galen's Watch. This study examined Echinaforce by A. Vogel Bioforce and strains of avian and swine-origin (H1N1) influenza.

The data presented in this work have shown that a standardized preparation of Echinacae has the potential to impair influenza virus propagation, including seasonal strains and strains of highly pathogenic avian influenza viruses as well as the new pandemic strain of swine origin at concentrations recommended for oral use and below. Furthermore the preparation does not induce emergence of resistant virus variants and is still active against strains that have become resistant to treatment with neuraminidase inhibitors. This potential, the availability and the lack of toxicity make this preparation an interesting option in the control and treatment of influenza virus infections
Echinaforce® (obtained from A. Vogel Bioforce AG, Roggwil, Switzerland) is a standardized preparation derived by ethanol extraction of freshly harvestedEchinacea purpurea herb and roots (95:5).
