Fragrant rue is a perennial plant with a distinct aroma. The stem is erect, 10-30 cm high. Inflorescence glabrous. The leaves are simple, arranged alternately, without leaflets, pliform-triangular, doubly or triply divided with elongated-inverted ovoid, dull lobes. Flowers bisexual, regular, yellow, arranged at the top of the plant, in liquid shield-shaped inflorescences. Petals four. Fruit - a round, four-socket box. Fragrant rue flowers in June-July. The fruits ripen in September.
The flowers of the fragrant rue are proto-androus and are pollinated by insects (most often tiny flower flies). During flowering, the rue is able to move parts of the flower, which increases its pollination capabilities. At the beginning of flowering, it does not allow the plant to self-pollinate, but towards the end of flowering, on the contrary, it is also able to self-pollinate.
Fresh or dried plant is used for medicinal purposes. The fragrant rue is harvested during its flowering period. Collect the above-ground part of the plant with leaves, and as a rule do it with rubber gloves, because the juice of the plant can cause serious skin burns and swelling. The plant can be dried spread on sieves or tied in bundles, in a well-ventilated and shaded place. The finished drug is green in color and is stored in tightly sealed glass or metal containers, protected from sunlight, as the plant fades in the sun and loses its value. The drug can be stored for two years.
