Couch Grass (Elytrigia repens (syn. Elymus repens))
Couch grass is a widespread grass whose rhizomes have been used traditionally to support urinary comfort and gentle fluid balance. Folk preparations most often use the dried rhizome as a tea or decoction.
What it is
Couch grass is a perennial grass found across Europe, North Africa, and parts of Asia and North America. The medicinally used part is typically the rhizome (underground stem), which is long and creeping.
Traditional uses
Traditional sources describe couch grass rhizome as a mild diuretic and soothing herb for the urinary tract. It has also been used in folk practice for supportive care in gout, rheumatic discomfort, and skin-related complaints.
Traditional preparations
Rhizome decoction (folk): Simmer a small amount of dried rhizome in water for 10 minutes, strain, and take in divided servings.
Soaking infusion (folk): Some traditional approaches steep the rhizome for many hours, strain, and drink in portions.
Baths (folk): Herbal baths using couch grass (sometimes combined with burdock root) are described in folk traditions for general skin comfort.
Practical guidance
For any diuretic herb, hydration and electrolyte balance matter. If you have persistent urinary symptoms, fever, or flank pain, seek medical care promptly.
Safety and precautions
- If you have kidney disease, heart failure, or take diuretics, consult a clinician before using diuretic herbs.
- Avoid use if you have fluid or electrolyte restrictions prescribed by your clinician.
- Stop use and seek advice if urinary symptoms worsen or persist.
