Couch Grass
a grass (Triticum repens) sometimes called in books creeping wheat-grass. It has long spikes, the spikelets with four to eight flowers. It is very common in fields and waste places. When occurring as a weed in cornfields, its long, creeping root renders it difficult of extirpation. Couch grass is a diuretic and aperient, and is useful in cases where the mucous membrane of the urinary tract is irritated or inflamed, as in irritation of the bladder, gonorrhea, etc.
