Couch grass has been used in herbal medicine since classical Greek times where it was recommended by Dioscorides for “stone in the bladder”. One of the common names is dog grass which comes from the fact that sick dogs will dig up the root and eat it. Culpepper said “…watch the dogs when they are sick and they will quickly lead you to it [1].
