What is echinacea and how does it support immunity?
Echinacea is a plant native to North America that has been used for centuries to strengthen the immune system and alleviate common cold symptoms. It contains polysaccharides, alkylamides, and cichoric acid derivatives that activate immune cells and increase the body's resistance to infections. As a supplement, echinacea is available in capsule, tincture, and tea forms.
