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.
