Couch Grass

Couch grass is the dried rhizome of Elymus repens (also listed as Agropyron repens), a perennial grass widespread across Europe, Asia and North America, whose creeping underground stems are used in herbal preparations. Nustras supplies it as dried cut rhizome, milled powder and extract powder. The rhizome contains the polysaccharide triticin, mucilage, sugar alcohols including mannitol, and a small amount of essential oil.

Couch grass is formulated into botanical supplements in capsule, tablet and liquid form, into herbal tea blends of the urinary-tract category alongside nettle and birch leaf, and into tinctures and fluid extracts.

Supplied as pale yellow to straw-coloured cut rhizome or a light beige powder with a faint odour and a slightly sweet taste. Botanical identity is confirmed by macroscopic examination and thin-layer chromatography; cut size, moisture and ash are standardised to specification. Heavy-metal, pesticide and microbial limits are supplied to specification and confirmed on each lot's certificate of analysis.

Nustras supplies couch grass in bulk commercial quantities, in food-grade bags and fibre drums, to manufacturers and formulators internationally, with a certificate of analysis, specification sheet and country-of-origin documentation on every lot. Couch grass rhizome is an accepted botanical ingredient in major supplement markets; buyers confirm the plant part, preparation and permitted claim for their application.
