Elecampane (Inula), a genus of Composite, allied to Aster. The only important species is the common Elecampane (I. Helenium), a native of damp meadows in the middle and south of Europe, rather rare in Britain, but not uncommon in the long-settled parts of North America. This plant was formerly much cultivated for its medicinal root, but is now comparatively neglected. The flowers are sometimes used to adulterate arnica.
