White Plains, New York, March 1, 2016 —
Echinacea supplements are a popular choice for preventing colds and treating cold symptoms, but do they really work? And, with so many different types of Echinacea marketed, how do you know which one to choose? To answer these questions, ConsumerLab.com recently reviewed the clinical evidence and purchased Echinacea supplements, testing them to see whether they contained their expected amounts of phenolic compounds expected from Echinacea. It also tested for contamination with the heavy metals lead, cadmium and arsenic, and microbes such as Salmonella
and E. coli
if the product was made with whole parts of plants (as opposed to extracts).
ConsumerLab.com's tests found that one product was contaminated with lead and two other products did not seem to provide the amounts of Echinacea expected from their labels, as determined by chemical testing. It also identified a product which failed to disclose the amount of Echinacea it actually contains — a violation of FDA rules. Among the products which were Approved for Quality by ConsumerLab.com (including four products tested through CL's voluntary Quality Certification Program
), those which were closest to what has been shown to work clinically were identified.

. The report summarizes the clinical evidence regarding the use of Echinacea, including differences between species (such as E. purpurea
and E. angustifolia
), plant parts (such as aerial and root) and forms (extracts and herb powders). It also discusses dosage, what to look for on labels, how to use Echinacea, and potential side-effects.
