DESCRIPTION

Medicinal Parts: The medicinal parts are the herb collected

during the flowering season and dried, the fresh aerial parts

collected during the flowering season, and the whole plant.

Flower and Fruit: The flowers are in 2- to 6-blossomed false

whorls in the axils of the foliage leaves. The individual

flowers are 1 to 2 cm long with distinct pedicles and

bracteoles that are 1 to 1.5 mm long. The calyx is bilabiate

and tubular, with 5 tips. The bilabiate corolla is 15 to 22 mm

long, usually blue-violet but occasionally red-violet or white.

The fruit is a nut of about 2 mm.

Leaves, Stem and Root: This perennial herb grows 15 to 60

cm high and has a creeping main stem, which roots at the

lower nodes and keeps its leaves in winter. The quadrangular

stem is up to 2 mm thick and often tinged with blue-violet, as

are the petioles. The leaves are crossed opposite, long-

petioled, reniform to broadly cordate, crenate; dark green

above and paler green beneath.

Characteristics: The plant has a mild unpleasant smell; the

taste is hot and bitter.

Habitat: Ground Ivy is a common wild plant in Europe.
