The Claim
Proponents claim that regular echinacea supplementation enhances the immune system, making it more efficient in fighting off various pathogens.
Origin
This belief has been fueled by in vitro studies showing enhanced immune activity and is frequently mentioned in health and wellness publications.
What Science Says
Clinical evidence supporting overall immune enhancement is limited. A 2016 meta-analysis in Advances in Therapy analyzed randomized controlled trials and found inconsistent results regarding immune markers such as cytokine levels. Effects vary depending on the formulation and study design, leading to no consensus on its efficacy for general immune support.
Verdict
Partially True
