Subvarieties include southern giant curled mustard, which resembles a headless cabbage such as kale, but with a distinct horseradish-mustard flavor. It is also known as green mustard cabbage.
The leaves, seeds, and stems of this mustard variety are edible. The plant appears in some form in African, Pakistani, Bangladeshi, Italian, Indian, Chinese, Japanese, Korean, and African-American (soul food) cuisine. Cultivars of B. juncea are grown as greens, and for the production of oilseed. In Russia, this is the main variety grown for production of mustard oil. It is widely used in canning, baking and margarine production in Russia, and the majority of table mustard there is also made from this species of mustard plant.
The leaves are used in African cooking, and all plant components are used in Indian cuisine, particularly in mountain regions of Nepal, as well as in the Punjab cuisine of India and Pakistan, where a dish called sarson da saag (mustard greens) is prepared. B. juncea subsp. tatsai, which has a particularly thick stem, is used to make the Indian pickle called achar, and the Chinese pickle zha cai.
The mustard condiment made from the seeds of the B. juncea is called brown mustard and is considered to be spicier than yellow mustard. The Gorkhas of Darjeeling and Sikkim prepare pork with mustard greens (also called rayo in Nepali). It is usually eaten with relish with steamed rice, but could also be eaten with chapati (griddle breads). Brassica juncea (especially the seeds) is more pungent than the closely related Brassica oleracea greens (kale, broccoli, collard greens, as common examples), and is frequently mixed with these milder greens in a dish of "mixed greens".
Chinese and Japanese cuisines also make use of mustard greens. In Japanese cuisine, it is known as takana and often pickled for use as filling in onigiri or as a condiment. A large variety of B. juncea cultivars are used, including zha cai, mizuna, takana (var. integrifolia), juk gai choy, and xuelihong. Asian mustard greens are most often stir-fried or pickled. A Southeast Asian dish called asam gai choy or kiam chai boey is often made with leftovers from a large meal. It involves stewing mustard greens with tamarind, dried chillies and leftover meat on the bone.
Brassica juncea is also known as gai choi, siu gai choi, xaio jie cai, baby mustard, Chinese leaf mustard or mostaza.

Vegetable growers sometimes grow mustard as a green manure. Its main purpose is to act as a mulch, covering the soil to suppress weeds between crops. If grown as a green manure, the mustard plants are cut down at the base when sufficiently grown, and left to wither on the surface, continuing to act as a mulch until the next crop is due for sowing, when the mustard is dug in. In the UK, summer and autumn-sown mustard is cut down from October. April sowings can be cut down in June, keeping the ground clear for summer-sown crops. One of the disadvantages of mustard as a green manure is its propensity to harbor club root.
This plant is used in phytoremediation to remove heavy metals, such as lead, from the soil in hazardous waste sites because it has a higher tolerance for these substances and stores the heavy metals in its cells. In particular, Schneider et al. found that Brassica juncea was particularly effective at removing cadmium from soil. Removal of heavy metals concludes with the plant being harvested and properly discarded. Phytoremediation has been shown to be cheaper and easier than traditional methods for heavy metal reduction in soils. In addition, it has the added benefit of reducing soil erosion, reducing cross-site contamination.
