Botanical Overview
Echinacea (Echinacea purpurea) belongs to the Asteraceae family. Limited but reliable traditional records indicate this plant has recognized medicinal applications in one or more healing traditions. The daisy family (Asteraceae) is one of the largest plant families, characterized by composite flower heads (capitula) that contain many small florets surrounded by bracts. Plants range from tiny alpine herbs to large tropical trees. The family includes many medicinally important species with bitter compounds and essential oils.
General Description
It is native to parts of eastern North America and present to some extent in the wild in much of the eastern, southeastern and midwestern United States, as well as in the Canadian Province of Ontario. It is most common in the Ozarks, the Mississippi Valley, and the Ohio Valley. Its habitats include dry open woods, prairies, and barrens.
