Double-blind placebo controlled trial of the anxiolyticeffects of a standardized Echinacea extract. József Haller,| Laszlo Krecsak| János Zámbori. Phytotherapy Research.2019;1–9.
Conclusion: “These findings suggest that particular Echinacea preparations have significant beneficial effects on anxiety in humans.”
Conflict of interest statement: JH is one of the authors of a US patent on the anxiolytic effects Echinacea preparations.
Comment: I don’t usually bother to write about supplements because so little evidence supports their benefits over placebos. This study finds small better-than-placebo benefits for this particular Echinacea supplement, presumably the one covered by the first author’s patent. I’d be happier with independently funded research. In the meantime, the European Food Safety Authority continues to have doubts. Will this study make that agency change its collective mind? We shall see.
