Scientific Effect
Echinacea, known as the Coneflower, is a plant native to North America. It has demonstrated effects on immune function, especially against the common cold.
Clinical Study
Echinacea purpurea-derived alkylamides exhibit potent anti-inflammatory effects and alleviate clinical symptoms of atopic eczema.
Results
"...Echinacea purpurea-derived alkylamides shows great potential in alleviating cutaneous symptoms of Atopic eczema..."
