Ruda plant, also known as rue, common rue, or herb-of-grace, is a species of Ruta graveolens grown as an ornamental plant and herb. It is native to the Balkan Peninsula and is grown throughout the world in gardens, especially for its bluish leaves, and sometimes for its tolerance of hot and dry soil conditions. Ruda plant is also cultivated as a culinary herb and to a lesser extent as an insect repellent and incense. It is traditionally used in Central Asia as an insect repellent and room deodorizer. Ruda plant is believed to have the power to cleanse and purify spaces and is one of the more popular plants used in purification rituals. It is also used in purifying baths to rid the bather of evil spirits or negative influences. Ruda plant has a long history of use in traditional medicine, especially in Maya culture and Central American medicine. Modern research has provided evidence for some of its beneficial properties. However, it is important to note that rue can be toxic and should be used with caution.
