Echinacea can be found in health supplements and herbal teas, especially those indicated for immune support.

Echinacea extract is made using either one or a blend of extracts from the roots, seeds, flowers and leaves. Echinacea extract is usually made by steeping the plant materials in distilled water.

Researchers, using advanced genetic testing and a variety of other techniques, have determined that Echinacea angustifolia, and Echinacea pallida are in fact not distinct species but rather varieties. Echinacea purpurea is however, still considered a distinct species. There is much discussion about which type of Echinacea is the best but safe and effective supplements can be made from both E. angustifolia and E. purpurea
