|Common rue in flower|
Ruta graveolens, commonly known as rue, common rue or herb-of-grace, is a species of Ruta grown as an ornamental plant and as an herb. It is native to the Balkan Peninsula. It is now grown throughout the world in gardens, especially for of its bluish leaves.and also sometimes for its tolerance of hot and dry soil conditions. It is also cultivated as a medicinal herb, as a condiment and, to a lesser extent, as an insect repellent.
The Tacuinum Sanitatis, a medieval handbook on wellness, lists these properties of rue:
- Nature: Warm and dry in the third degree.
- Optimum: That which is grown near a fig tree.
- Usefulness: It sharpens the eyesight and dissipates flatulence.
- Dangers: It augments the sperm and dampens the desire for coitus.
- Neutralization of the Dangers: With foods that multiply the sperm.
In Kashmiri house, Rue seeds (local Kashmiri name "Izband" ) are roasted and fumes from seeds are spread across all rooms of house to keep evil away on special occasions like birthday, marriages etc.Also helps as insect repellent.
Rue does have a culinary use if used sparingly, but it is bitter and gastric discomfort may be experienced by some individuals. Although used more extensively in former times, it is not an herb that is typically found in modern cuisine, and is today largely unknown to the general public and most chefs, and unavailable in grocery stores. It is a component of berbere, the characteristic Ethiopian spice mixture, and as such is encountered in Ethiopian cuisine.
- It was used extensively in ancient Near Eastern and Roman cuisine (according to Ibn Sayyar al-Warraq and Apicius).
- Rue leaves and berries are an important part of the cuisine of Ethiopia.
- Rue is used as a traditional flavouring in Greece and other Mediterranean countries.
- In Istria (a region in Croatia), and in Northern Italy, it is used to give a special flavour to grappa/raki and most of the time a little branch of the plant can be found in the bottle. This is called grappa alla ruta.
- Seeds can be used for porridge.
- The bitter leaf can be added to eggs, cheese, fish, or mixed with damson plums and wine to produce a meat sauce.
- In Italy in Friuli Venezia-Giulia, the young branches of the plant are dipped in a batter, deep-fried in oil, and consumed with salt or sugar. They are also used on their own to aromatise a specific type of omelette.
- Used in Old World beers as flavouring ingredient.
Most cats dislike the smell of it, and it can therefore be used as a deterrent to them (see also Plectranthus caninus).
In South India, rue is recommended for home gardens to repel snakes (however the effectiveness is unknown).
Cell cultures produce the coumarins umbelliferone, scopoletin, psoralen, xanthotoxin, isopimpinellin, rutamarin and rutacultin, and the alkaloids skimmianine, kokusaginine, 6-methoxydictamnine and edulinine.
The bitter taste of its leaves led to rue being associated with the (etymologically unrelated) verb rue "to regret". Rue is well known for its symbolic meaning of regret and it has sometimes been called "herb-of-grace" in literary works. It is one of the flowers distributed by the mad Ophelia in William Shakespeare's Hamlet (IV.5):
- "There's fennel for you, and columbines:
- there's rue for you; and here's some for me:
- we may call it herb-grace o' Sundays:
- O you must wear your rue with a difference..."
It was planted by the gardener in Richard II to mark the spot where the Queen wept upon hearing news of Richard's capture (III.4.104–105):
- "Here did she fall a tear, here in this place
- I'll set a bank of rue, sour herb of grace."
It is also given by the rusticated Perdita to her disguised royal father-in-law on the occasion of a sheep-shearing (Winter's Tale, IV.4):
- "For you there's rosemary and rue; these keep
- Seeming and savour all the winter long."
It is used by Michael in Milton's Paradise Lost to give Adam clear sight (11.414):
- "Then purg'd with euphrasy and rue
- The visual nerve, for he had much to see."
Rue is used by Gulliver in "Gulliver's Travels" (by Jonathan Swift) when he returns to England after living among the "Houyhnhnms". Gulliver can no longer stand the smell of the English Yahoos (people), so he stuffs rue or tobacco in his nose to block out the smell. "I was at last bold enough to walk the street in his (Don Pedro's) company, but kept my nose well with rue, or sometimes with tobacco".
Rue is mentioned in the Bible, Luke 11.42: "But woe unto you, Pharisees! For ye tithe mint and rue and all manner of herbs".
In mythology,[clarification needed] the basilisk, whose breath could cause plants to wilt and stones to crack, had no effect on rue. Weasels who were bitten by the basilisk would retreat and eat rue in order to recover and return to fight.
Rue is considered a national herb of Lithuania and it is the most frequently referred herb in Lithuanian folk songs, as an attribute of young girls, associated with virginity and maidenhood. It was common in traditional Lithuanian weddings for only virgins to wear a rue (ruta) at their wedding, a symbol to show their purity. Likewise, rue is prominent in the Ukrainian folklore, songs and culture.
In the Ukrainian folk song "Oi poli ruta, ruta" (O, rue, rue in the field), the girl regrets losing her virginity, reproaching the lover for "breaking the green hazel tree". "Una Matica de Ruda" is a traditional Sephardic wedding song.
"Chervona Ruta" (Червона Рута—"Red Rue")—a song, written by Volodymyr Ivasyuk, a popular Ukrainian poet and composer. Pop singer Sofia Rotaru performed the song in 1971. More recently Rotaru performed in a rap arrangement.
