“Stray sod” is a general term used here to refer to any plant that, if trodden upon, causes travelers to lose their way. Stray sods have been reported primarily from France and Ireland, and come about in a number of ways. Usually they are specific herbs with magical properties that grow along footpaths. At other times they form over the graves of unbaptised children, or are patches of grass enchanted by fairies. They themselves may be fairies or inhabited by fairies.
No matter the origin, the result is always the same. A solitary traveler at night will inadvertently step on a stray sod, and no matter how good their sense of direction, they immediately lose their path. All landmarks seem to vanish, all roads are dead ends. The unfortunate victim is compelled to wander aimlessly through the night, trudging through hedges and thorns, crossing rivers, slogging through marshes, and feeling their way through thickets. The spell is broken at daybreak, when they find themselves with their clothes torn and stained, their hands and feet bleeding, and miles away from home.
When this happens it is advised to turn one’s coat inside out to counteract the spell. Other remedies include the usage of metal as abhorrent to fairies, or finding certain plants or benevolent spirits to regain one’s bearings.
The stray sod is known as the herbe à adirer (“herb of misplacement”) in Anjou, the herbe à la recule (“herb of turning back”) in Besançon, the herbe d’oubli (“herb of forgetfulness”) in Brittany and Lorraine, the egaire in Normandy, and the herbe maudite (“damned herb”) or herbe des tournes (“herb of turning”) in Saintonge. The ar iotan (“golden herb”) of Brittany is inhabited by a spirit that shines like a glowworm; touching a piece of wood or metal breaks its spell, as does changing horseshoes on one side. The lezeuen eur (“golden herb”) and the lezuenn er seudann (“herb of dizziness”) of the Morbihan cause their victims to walk in circles until daybreak. The herbe royale (“royal herb”) of Saint-Mayeux causes even horses to lose their way. The herbe d’engaire of the Berry grows in vast plains, and causes those who step on it to lose sight of the path entirely. The tourmentine (Potentilla erecta, formerly Potentilla tormentilla) of Forez, which causes disorientation for 12 hours, can be countered by the parisette (Paris quadrifolia), a plant whose fallen seeds guide travelers by pointing in the right direction.
The faud shaughran of Ireland induces a sensation of flying, of being incapable of stopping until one is over twenty or thirty miles from home. There is a herb that counteracts its effects, but it is known only to the initiated. The similar fair-gortha causes unnatural hunger and craving for food if stepped on. One man in County Leitrim turned his coat and hat inside out but was unable to find his way home, ending up miles away from his destination.
