Medicinal uses(Warning!)

The seed is used in the treatment of tumours in China[16]. In Korea, the seeds are used in the treatment of abscesses, colds, lumbago, rheumatism, and stomach disorders[16]. Ingestion may impart a body odour repellent to mosquitoes[16]. In Java the plant is used as an antisyphilitic emmenagogue[16]. Leaves applied to the forehead are said to relieve headache[16]. The Chinese eat the leaves in soups for bladder inflammation or haemorrhage[16].

Ecological Functions

Green manure, Repellant

There is some evidence that if this plant is grown as a green manure it is effective in reducing soil-borne root rots in pea crops[10]. This is attributed to chemicals that are given off as the plants decay[10].

Forage

Shelter

Nothing listed.

Propagation

Seed

Sow in situ from early spring to early autumn in order to obtain a succession of edible leaves. Plants may respond to lengthening days and dry, hot weather by bolting to flower[10]. There are about 5,660 - 6,000 per 0.01 kg (1/3 oz)[16].


Cultivation

Succeeds in full sun in most well-drained moisture-retentive fertile soils[17][18][10]. Prefers a heavy soil and some shade[17]. Dislikes very hot weather[7]. Plants tolerate high rainfall and, although fairly deep rooted, are not very drought resistant[10]. Tolerates a pH in the range 4.3 to 8.3.

Brown mustards is widely cultivated for its edible seed which is used to make the condiment 'brown mustard' and is also sprouted as the mustard of mustard and cress[19][18]. It has only 70% of the pungency of black mustard (B. nigra) but can be harvested mechanically so is more viable commercially[3]. This species has also been cultivated in the Orient for many hundreds of years and a wide diversity of forms has been developed with edible leaves, stems, roots and seeds. These forms have been classified by the botanists as follows and separate entries have been made for each of them.

    B. juncea crispifolia. The curled or cutleaf mustards, this group has attractively curled edible leaves.
    B. juncea foliosa. The leaf mustards have quite large smooth-edged edible leaves.
    B. juncea japonica. Rather similar to B. juncea crispifolia and combined with that group by some botanists.
    B. juncea multiceps. The multishoot mustard group.
    B. juncea napiformis. A form with a swollen edible root.
    B. juncea rugosa. Large somewhat cabbage-like edible leaves.
    B. juncea strumata. A form with large edible leaf stalks.
    B. juncea tumida. A form with swollen edible stems.

Plants take from 2 - 5 months from sowing to maturity, depending on the season and the cultivar[10]. They prefer a fairly high stable temperature and are well adapted to short day length[18]. Many are best grown in warmer climates than Britain but there are several cultivars that grow well in this country[10]. Plants have a rooting depth of between 90 - 120 cm[16].

A good bee plant[15].
