| | | | Couch Grass | | | Gardeners hate it - herbalists love it! Couch grass is a pernicious weed
that spreads rapidly by way of underground roots and rhizomes strangling
everything in its path. This aggressive perennial grass is found in all
parts of the world and has been used in medicine since the first century.
Couch grass had many uses in traditional medicine in many cultures,
especially for kidney ailments, and the roots are still used by
traditional peasants in South China and Hong Kong to make a herbal tonic
tea. Couch grass is recognized by the German E Commission for kidney and
urinary tract disorders, and its benefits are supported by in vitro
and animal studies. | |

Browse Sections | View Couch Grass products | | | Description | | | Found in Europe, the Americas, Northern Asia, and Australia, couch grass
is considered by many to be an invasive weed. This vigorous perennial can
grow to 32 in (80 cm) in height and is harvested throughout the year.
Couch grass spreads by way of its long, creeping rhizome, and it is
identified by its slender leaves, and erect spikes bearing green flowers
aligned in two rows. The part of the plant with the greatest concentration
of active ingredients is its fleshy underground stem, collected in spring
or autumn.
Browse Sections | View Couch Grass products | | | Traditional Internal Uses | | | Couch grass roots have been used as a medicine since the time of
Dioscorides in the first century, and even sick dogs eat the leaves to
produce a healing vomit. In Europe, it is still used as a tisane. Gerard
wrote of couch grass, "...it openeth the stoppings of the liver and
reins without any manifest heat...", and Nicholas Culpeper, one of
the formost figures in the history of herbal medicine, also praised its
virtues for diseases of the kidneys.
During the early twentieth
century, Couch Grass was used in France as a home remedy to soothe sore
throats and to help "sweat out" illnesses.
Couch grass is
stated to possess diuretic properties. It has been used for cystitis,
urethritis, prostatitis, benign prostatic hypertrophy, renal calculus,
lithuria, and specifically for cystitis with irritation or inflammation of
the urinary tract.
Couch grass has been taken to ensure that
adequate levels of friendly bacteria are kept in check. Couch grass has a
high mannitol and mucilage content making it useful as supplement offering
upper respiratory support and maintenance.
Couch Grass is widely
considered effective for building resistance to infections and urinary
tract infections, and it may provide relief in conditions such as
bronchitis, colds, coughs, fever, and sore throats. Other traditional folk
uses of this herb include bladder infections, urinary stones, gout, pain
from rheumatism, chronic skin problems, and constipation.
The
German E Commission endorses the use of couch grass for irrigation
therapy, for inflammatory diseases of the urinary tract, and for the
prevention of kidney gravel.

Browse Sections | View Couch Grass products | | | Pharmacological Summary | | | Limited chemical data are available for couch grass and little scientific
evidence was located to justify the traditional herbal uses. Agropyrene is
regarded as the main active principle in couch grass on account of its
antibiotic effect, although the presence of agropyrene in the volatile oil
has been disputed.(1)
The sugar, mannitol, is present in large
quantities in this herb, and is known as a standard 'osmotic diuretic',
that is, it is absorbed whole from the gut and excreted largely by the
kidney tubules. Its presence in the tubules means that extra water has to
be retained in order to maintain osmotic pressure. The saponins and
vanillin, also have diuretic properties. Silica, present as 30% of the
inorganic residue, justifies this herb's use in the treatment of
slow-healing wounds and to strengthen the lungs and other tissues. The
antibiotic substance help to limit infections in the urinary tubules and
elsewhere.

Couch grass is stated to
exhibit diuretic and sedative activities in rats and mice, respectively.
Broad antibiotic activity has been documented for agropyrene and its
oxidation product. An ethanolic extract was found to exhibit only weak
inhibition (14%) of carrageenan-induced inflammation in the rat
paw.(2)
Couch grass has been reported to be phytotoxic with
flavonoid components implicated as the active constituents.(3)
