Despite its usefulness this herb is not well-loved, especially not by gardeners or farmers, as it loves to invade their well-tilled land. Its long, fragile rhizomes make hard work of trying to control it since every time one pulls one out more will sprout from any bits that might have broken off in the process. It loves loose soil and will take advantage of it given half a chance. Yet, we should not hate it, for it has many beneficial properties. It is one of those protective herbs that bind the soil, protecting the earth's top soil against the wear and tear by the weather and other adverse factors, thus being an excellent ally in the fight against erosion. Its sweet rhizomes and roots are also quite nourishing and have been a welcome source of nutrients in times of scarcity. Many animals will instinctively seek out this humble weed to cure themselves when they are sick, which is why Couchgrass is also sometimes known as Dog's Grass.
Couchgrass is a soothing diuretic that will increase the flow of urine without putting extra strain on the kidneys. It is used for all manner of urinary infections, cystitis, urethritis and the like. It soothes the irritation of gravel and may help to dissolve it. It is also indicated for enlarged prostate and prostatitis. Along with other diuretic herbs it can be a supportive remedy for cases of arthritis, rheumatism and gout. It is a safe and effective herb, which can be taken over extended periods of time.
Not much has been written about the magical associations of this herb, although one of its alternate names is witch grass. It persistent nature suggests it may be useful to strengthen endurance, not in the sense of sheer power, but in the sense of trying, and trying again, no matter how many times ones efforts are blocked or undermined. It also lends itself to helping to dissolve hindrances and blockages of flow.
