Rute Flowers

Ruta (commonly known as rue) is a genus of strongly scented evergreen subshrubs, 20–60 cm tall, in the family Rutaceae, native to the Mediterranean region, Macaronesia and southwest Asia. There are perhaps 8 to 40 species in the genus. The most well-known species is Ruta graveolens (rue or common rue).

The leaves are bipinnate or tripinnate, with a feathery appearance, and green to strongly glaucous blue-green in colour. The flowers are yellow, with 4–5 petals, about 1 cm diameter, and borne in cymes. The fruit is a 4–5-lobed capsule, containing numerous seeds.

Extracts from rue have been used to treateyestrain, sore eyes, and as insect repellent.
Rue has been used internally as an antispasmodic, as a treatment for menstrual problems, as an abortifacient, and as a sedative.
The refined oil of rue is an emmenagogue and was cited by the Roman historian Pliny the Elder and the gynecologist Soranus as a potent abortifacient (inducing abortion).

Caution should be taken with using rue topically. Applied to the skin with sun exposure, the oil and leaves can cause blistering.
Some people are much more sensitive than others.

Rue has a culinary use, but since it is bitter and gastric discomfort may be experienced by some individuals, it is used sparingly. Although used more extensively in former times, it is not an herb that is typically found in modern cuisine. Today it is 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 has a variety of other culinary uses:

It was used extensively in ancient Near Eastern and Roman cuisine (according to Ibn Sayyar al-Warraq and Apicius).
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 flavouringingredient.

Rue is also grown as an ornamental plant, both as a low hedge and so the leaves can be used in nosegays.

Most cats dislike the smell of it, and it can, therefore, be used as a deterrent to them (see also Plectranthus caninus).

Caterpillars of some subspecies of the butterfly Papilio machaon feed on rue, as well as other plants. The caterpillars of Papilio xuthus also feed readily on it.

In South India, rue is recommended for home gardens to repel snakes (however the effectiveness is unknown).

Rue is also a common ingredient in witchcraft and spell making. During the Middle Ages it was a symbol of recognition between witches. The Catholic Church also used a branch of rue to sprinkle holy water on its followers during this time known as the "herb of grace."
