Echinacea

Echinacea, a renowned herbal remedy, has been celebrated for its potential benefits in supporting immune health and managing symptoms of upper respiratory infections (URIs) such as the common cold. With active compounds like alkylamides, polysaccharides, and cichoric acid, echinacea is believed to enhance immune function by modulating cytokine activity and stimulating white blood cell response. However, the scientific community remains divided on its efficacy due to varying study quality and product formulations.
