Couch grass, scientifically known as Agropyron repens, originates from Europe and Central Asia.

Traditionally used for promoting UT health, including normal bladder and kidney function, the rhizomes, roots and seeds of couch grass are used by traditional herbalists around the world today1.*

The phytochemical profile of the plant reveals an abundant variety of chemical constituents that contribute to its beneficial effect. Couch grass contains flavonoids, saponins, glycosides phenol compounds, triticin, mucilaginous substances, volatile oils, carbohydrates, iron and other minerals. Its extract is rich in mucous substances (different carbohydrates, produced by plants to store water for their growth). Triticin, a key component of the mucilage, is a polysaccharide molecule and major constituent of couch grass (3% to 8%). When excreted in the urine, it forms a thin layer on the epithelium of the urinary tract1.*

Saponins and vanillin are major constituents that support the cleansing function of UT, and many studies have documented the beneficial effect of couch grass on kidneys and bladder health2,3.*
