Its leaves are used in many dishes in India, Sri Lanka, and neighbouring countries. Often used in curries, the leaves are generally called by the name 'curry leaves', although they are also literally 'sweet neem leaves' in most Indian languages (as opposed to ordinary neem leaves which are very bitter and in the family Meliaceae, not Rutaceae).
It is a small tree, growing 4–6 m (13–20 feet) tall, with a trunk up to 40 cm (16 in) diameter. The aromatic leaves are pinnate, with 11–21 leaflets, each leaflet 2–4 cm (0.79–1.57 in) long and 1–2 cm (0.39–0.79 in) broad. The plant produces small white flowers which can self-pollinate to produce small shiny-black berries containing a single, large viable seed. Though the berry pulp is edible—with a sweet but medicinal flavour—in general, neither the pulp nor seed is used for culinary purposes.
The leaves are valued as seasoning in southern and west-coast Indian cooking, and Sri Lankan cooking, usually fried along with the chopped onion in the first stage of the preparation. They are also used to make thoran, vada, rasam and kadhi. They are also available dried, though the aroma is largely inferior.
The leaves of Murraya koenigii are also used as an herb in Ayurvedic medicine in which they are believed to possess anti-diabetic properties, but there is no high-quality scientific evidence for such effects. In the absence of tulsi leaves, curry leaves are used for rituals, such as pujas.
Seeds must be ripe and fresh to plant; dried or shriveled fruits are not viable. One can plant the whole fruit, but it is best to remove the pulp before planting in potting mix that is kept moist but not wet.
Stem cuttings can be also used for propagation.
