Agropyron repens (Graminae)
COUCHGRASS, TWITCHGRASS, DOGSGRASS
A notorious garden weed throughout the world, it is native to Europe but travelled with early explorers and settlers.
The roots have been used as a medicine since Dioscorides in AD77, and even sick dogs eat the leaves to produce a healing vomit. In Europe, it is still used as a tisane.
Long white rhizomes spread as a dense mat in the soil and produce clumps of grass blades. In midsummer,
a flowering spike appears with two rows of closely packed small flowers that look like rye.
Rhizome, collected in the spring.
A polysaccharide, triticin, and other carbohydrates such as inositol, mannitol, and mucilage;
volatile oil containing agropyrene.
Soothing; increases urine production.
Used for painful urinary tract problems, including inflammatory urinary tract conditions such as cystitis, kidney stones,
and prostatitis (inflammation of the prostate gland).
