Brassicaceae, formerly Cruciferae, the mustard family of flowering plants (order Brassicales), composed of 338 genera and some 3,700 species. The family includes many plants of economic importance that have been extensively altered and domesticated by humans, especially those of the genus Brassica, which includes cabbage, broccoli, Brussels sprouts, kale, kohlrabi, napa cabbage, turnip, and rutabaga. Other important agricultural crops in the family include horseradish, radish, and white mustard. A number of species—such as basket-of-gold, candytuft, and honesty—are grown as ornamentals, and some members of the family are considered invasive species in regions outside their native range.

Several regions in western and central Asia have been assumed to be the centre of origin of Brassica juncea. Brown mustard has been cultivated in Asia and Europe for thousands of years for its leaves and seeds. Presently, vegetable types of Brassica juncea are cultivated throughout southern and eastern Asia. Variation is greatest in China. 

In Asia, Europe and America, Brassica juncea is grown mainly for its seed used in the fabrication of brown mustard or for the extraction of vegetable oil. It has been introduced for this purpose locally in Africa, e.g. in the Mascarene Islands. In much of Europe Brassica juncea has replaced Brassica nigra as the main source of commercial mustard seed. Its mustard is spicier than the yellow type made from Brassica nigra. Mustard oil is one of the major edible oils in Bangladesh, India and Pakistan, appreciated for its special taste and pungency. In adjacent parts of the former Soviet Union it is used as a substitute for olive oil. In Western countries its use as edible oil is restricted because of the high erucic acid content. The oil is also used as hair oil and as lubricant. The oil of cultivars bred for extra high erucic acid content is used for industrial purposes. A peculiar use of mustard oil is to retard the fermentation process when making cider from apples. The seeds are also used in birdseed mixtures. The remaining seed meal is high in protein, but the high glucosinolate content makes it unacceptable for human or for monogastric-animal consumption.

Brown mustard is reported to have anodyne, aperient, diuretic, emetic and rubefacient properties. It is a folk remedy for arthritis, foot ache, lumbago and rheumatism. In China the seed is used as medicine against tumours. Ingestion may impart a body odour repellent to mosquitoes. Leaves applied to the forehead are said to relieve headache
