Some forms of Echinacea help prevent colds and cold-symptoms, but with so many different types Echinacea marketed, how do you know which one to choose? In this report, ConsumerLab.com explains which types of Echinacea have the most clinical evidence, what to look for on labels, how to use Echinacea, and, based on ConsumerLab.com's laboratory testing, which supplements are of best quality.
During our testing, we discovered one Echinacea product which was contaminated with lead and two products which don't seem to provide the amounts of Echinacea expected from their labels. We also reveal that one product doesn't even disclose how much Echinacea it contains — a violation of FDA rules.
Fortunately, we identified a number of quality products which provide the type and dose of Echinacea most likely to work.
In this comprehensive report about Echinacea, you'll get test results and quality ratings for 14 Echinacea supplements (including four that passed testing in our voluntary Quality Certification Program) and information about two additional Echinacea supplements similar to another which passed testing. You'll learn:
- Which Echinacea supplements passed or failed testing
- What to look for on labels: Echinacea species (such as E. purpurea and E. angustifolia), plant parts (such as aerial and root), forms (extracts and herb powders) and dosage
- Cost comparisons and which products offer the best value
- The evidence for other ingredients, like goldenseal, elderberry and zinc, which are often combined with Echinacea
- Concerns, cautions and side effects with echinacea
