Germander
Teucrium chamaedrys
DESCRIPTION
Medicinal Parts: The medicinal part is the herb collected
during the flowering season.
Flower and Fruit: The flowers are 10 to 12 mm long and are
erect. They are arranged on long pedicles in l-to-6 blos-
somed, false racemes inclined to one side. The calyx is
tubular-campanulate, often tinged with red-violet and is
pubescent. The corolla is usually carmine red, occasionally
white. The stamens and styles are exserted. The nutlet is
ovoid, 1.5 to 2 cm long, smooth, finely reticulate and has a
large, circular, attaching surface.
Leaves, Stem.and Root: The plant is a subshrub with a short-
lived main root from which grow long-reaching, branched,
jm, thin woody roots and a stem-producing runner. The stems
are usually erect and branched. The older branches are
decumbent; the younger ones erect, tough, round and lanate.
The branches are occasionally covered in glandular hairs,
which are often red-violet. The leaves are in close pairs and
are always covered in teeth. They are summer-green and
have distinctly protruding pinnatifid ribs.
Habitat: The plant is indigenous to the Mediterranean region
as far as Anatolia and the Urals.


Production: Germander is the aerial part of Teucrium
chamaedrys.

EFFECTS
The drug, which contains strong amaroids, is said to have a
cholagogic effect, but this has not been scientifically proven.
The toxic principle is therefore unknown. Higher doses or
poisoning results in hepatitis-like symptoms, which may
include liver cell necrosis.

INDICATIONS AND USAGE
Unproven Uses: Germander is used as a digestive aid, as a
rinse for gout, as weight-loss aid and for fever.
CONTRAINDICATIONS
The drug is highly toxic and should not be used (see
PRECAUTIONS).
PRECAUTIONS AND ADVERSE REACTIONS
Liver cell necrosis has been observed following intake of the
drug. Symptoms include jaundice and an elevated level of
aminotransferase in the blood. One case of death has been
recorded. For that reason, the drug is not to be administered.
DOSAGE
Mode of Administration: Germander is occasionally used in
tea mixtures (see PRECAUTIONS).
Daily Dosage: Dosages of more than 600 mg daily can cause
toxic effects.
