Quick review of Echinacea
As part of the Charms & Harms series in the Journal of Primary Care, Dr. Joanne Barnes, from the University of Auckland, in New Zealand distilled the evidence.
Highlights
- The results of studies of echinacea to prevent and treat upper respiratory infections are conflicting.
- There’s insufficient evidence to recommend a particular preparation or dosage regimen.
- The limited data indicate that echinacea preparations are well-tolerated, although allergic reactions may occur.
- Echinacea products differ in their pharmaceutical quality
- The implications of this for efficacy and safety should be considered.
The bottom line?
The article is a good 1-page review.
