The leaves, flower buds, and roots of this perennial native to the North American prairie have been traditionally used to support optimal immune function. Echinacea has been trusted far and wide by many to keep us at our healthiest and is a must-have when it comes to natural wellness. The liquid extract, taken in spray form or diluted with a little water, can also be used as a throat spray or mouth rinse to moisten tissue (it has a unique, refreshing flavor). To encourage healthy immunity, the extract is taken at doses of 1 teaspoon up to 5 times a day. At these dose ranges, Echinacea is a safe herb for short-term use.
