Murraya koenigii, curry tree sometimes known as Bergera koenigii, is a tropical to subtropical tree native to Asia that belongs to the Rutaceae family (which includes rue, citrus, and satinwood). M. koenigii is also known as sweet neem, despite the fact that it belongs to a different family than neem, Azadirachta indica, which is in the Meliaceae family. It is a little tree that grows 4-6 meters (13-20 feet) tall and has a trunk diameter of up to 40 cm (16 inches). The aromatic leaves are pinnate, with 11-21 leaflets, each measuring 2-4 cm (3/4-1 in) long and ½-3/4 in) wide. Small white flowers bloom on the plant, which can self-pollinate to yield small shiny-black drupes with a single huge viable seed. The berry pulp has a pleasant flavor and is edible. The tree is indigenous to the subcontinent of India. In India and, more recently, Australia, commercial plantations have been built. It thrives in well-drained, moisture-retentive soil in full sun or light shade, preferably away from the wind. When temperatures are at least 18 °C (64 °F), growth is more strong. Cinnamaldehyde and many carbazole alkaloids, such as mahanimbine, girinimbine and mahanine, are all present in the leaves, stems, bark, and seeds of the curry tree. In terms of nutrition, the leaves are high in vitamins B and C, carotenoids, beta-carotene, calcium, and iron. Fresh leaves are a necessary component of Indian cuisine and traditional healing. They're most commonly seen in southern and western Indian cuisine, where they're fried with vegetable oil, mustard seeds and chopped onions in the first stage of preparation. Thoran, vada, rasam and kadhi are also made with them. Fresh leaves are used as spice in South and Southeast Asian cuisines. The leaves are roasted and used in a soup called maju krueng in Cambodia, where they are known as sloek kontroap. The leaves are frequently cooked in Java to flavor gulai. Although dried versions are available, the aroma and flavor are very bad. It is possible to extract the oil and utilize it to manufacture fragrant soaps. Murraya koenigii leaves are also employed as a herb in Ayurvedic and Siddha medicine, where they are said to have anti-disease characteristics, but there is no high-quality clinical evidence for these effects. Humans may be poisoned by the seeds.
