Heath, or Erica, L. a genus of plants comprising 100 species, five of which are natives of Britain. The principal of these is the vulgaris, Common Heath or Ling. It grows on heaths and in woods ; flowers from June to August.

In the island of Islay, in the west of Scotland, a wholesome ale is prepared, by brewing one part of malt, and two parts of the young tops of heath, to which hops are occasionally added.

In England, the common heath is employed in making brooms and faggots, which last are used either as fuel in ovens, or for filling up drains before they are covered.— Horses, sheep, and goats, eat the tender shoots of heath. - The stalks and tops are of considerable service in tanning leather, especially for soles ; end, if woollen cloth be boiled in alum-water, and after-wards in a strong decoction of the tops, it will acquire a fine orange colour. - Bees are very partial to the flowers of this species; but, where heath abounds, the honey acquires 3 reddish tint.
