The Claim
Some individuals take echinacea at the first sign of a cold, believing it will reduce the duration and severity of symptoms. The idea is that echinacea can stimulate the immune system to fight off the virus more effectively.
Origin
This myth is propagated by anecdotal reports and early studies with positive outcomes, often highlighted in marketing campaigns by supplement manufacturers.
What Science Says
A 2015 systematic review in the Journal of Antimicrobial Chemotherapy assessed several trials and found no strong evidence that echinacea significantly shortens the duration of colds compared to placebo. While some studies report a mild reduction in symptom duration, the overall effect size is small and not clinically significant.
Verdict
Mostly False
