Rue (Ruta graveolens) is a genus of strongly scented evergreen subshrubs 2060 cm tall, in the family Rutaceae, native to the Mediterranean region, Macaronesia and southwest Asia. Rue is indigenous to Europe, but has now acclimatized to the conditions in the United States and is widely cultivated there.

While the terrible scent of the plant keeps insects away, the herb is also used to treat insect bites. Dehydrated leaves of the rue herb have reduced aroma owing to the evaporation of the volatile oil enclosed in them.
