In Europe, "Cicuta" was not distinguished from the similar genus "Conium" before the year 1500. She was nominated for the Pushcart Prize by The Conium Review. It is easily confused with the highly toxic water hemlock ("Conium maculatum"). Poison hemlock ("Conium maculatum") contains highly toxic amounts of coniine. The poison hemlock moth can be found wherever its host plant ("Conium maculatum") occurs. It should not be confused with "Conium maculatum", which is highly poisonous. "Conium maculatum" is the plant that killed Theramenes, Socrates and Phocion.
