Summary

Jew’s Mallow or Corchorus olitorius is a tropical, annual herb that is upright, branching, and slightly woody. The leaves are shiny and have leaf stalks. The flowers are yellow and small and form into clusters in the axils of the leaves. The fruit are rigged capsules. The seeds are dull grey and with four faces and one long point. The leaves are used in the treatment of cystitis, gonorrhoea, and dysuria. The seeds are purgative. The stem is the main source of jute used in sack cloth, paper etc. The wood is very light and soft and is used in making sulphur matches. The leaves and young fruits are used as a vegetable. The leaves are dried and used for tea and as a soup thickener. The seeds are edible as well.

Edible Uses

Edible Parts: Leaves  Seed  Shoots
Edible Uses: Tea

Leaves - raw or cooked[1, 27, 46, 61]. Young leaves are added to salads whilst older leaves are cooked as a pot-herb[2, 183, 269]. The young leaves and stem tops are eaten cooked and are slimy unless fried. The leaves quickly become mucilaginous when cooked[298]. High in protein[183]. The dried leaves can be used as a thickener in soups[183]. Leaves and young shoots are normally harvested when about 20 - 30cm long[300]. Leaves can be sun dried, pounded to flour, then stored for a significant time.

Medicinal Uses

Plants For A Future can not take any responsibility for any adverse effects from the use of plants. Always seek advice from a professional before using a plant medicinally.
Demulcent  Diuretic  Febrifuge  Tonic

The leaves are demulcent, diuretic, febrifuge and tonic[ 240 ]. They are used in the treatment of chronic cystitis, gonorrhoea and dysuria[ 240 ]. A cold infusion is said to restore the appetite and strength[ 269 ]. The seeds are purgative[ 240 ]. Injections of olitoriside, an extract from the plant, markedly improve cardiac insufficiencies and have no cumulative attributes; hence, it can serve as a substitute for strophanthin[ 269 ].

Our new book Edible Shrubs is now available.

Edible Shrubs provides detailed information, attractively presented, on over 70 shrub species. They have been selected to provide a mix of different plant sizes and growing conditions. Most provide delicious and nutritious fruit, but many also have edible leaves, seeds, flowers, stems or roots, or they yield edible or useful oil.

Other Uses

Fibre  Wood

Other Uses: A fibre is obtained from the stems, it is the main source of jute[ 46 , 61 , 200 ] but is considered to be inferior to the fibre obtained from C. capsularis[ 61 ]. The fibre is somewhat coarse and is used mainly for sackcloth etc[ 57 ]. The stems are harvested when the plant is in flower and are then retted (allowed to begin to rot) so that the fibre can be extracted[ 171 ]. This species tends to branch making fibre extraction more difficult[ 114 ]. Growing the plants very close together will prevent some of the branching. If used in making paper, the fibres are cooked for 2 hours with lye and then ball milled for 4½ hours. The paper is grey/buff[ 189 ]. The very light and soft wood is used in making sulphur matches[ 158 ].

Cultivation details

Plants grow well in the lowland tropics, up to an elevation of around 700 metres[ 300 ]. They are reported to tolerate an annual precipitation between 400 and 4290mm, an annual average temperature range of 16.8 to 27.5°c[ 269 ]. Prefers a very fertile, humus-rich, well-drained alluvial soil, though it is extremely tolerant of soil conditions[ 169 , 300 ]. It grows best in a hot humid climate[ 169 ]. Tolerates very wet conditions according to one report[ 57 ] whilst another says that it does not tolerate waterlogged soils[ 169 ]. Some cultivars are sensitive to excess water in the soil, especially when they are young[ 300 ]. Tolerates a pH in the range of 4.5 to 8.2[ 269 ]. There are two important cultivar-groups:- Olitorius Group. These are the forms mainly grown for their edible leaves. They are characterized by a plant height lower than 2 metres, often not more than 1 metre, and a more or less heavily branched plant habit. There are many named forms within this group[ 299 ]. Textilis Group. These are the forms mainly grown for their fibre. The plants are usually larger, up to 4 metres, perhaps even 5 metres tall, and only slightly branched at the top[ 299 ]. The first harvest, by cutting shoots 20 - 30cm long, may take place 4 - 6 weeks after transplanting, at a height of 10 - 20cm above the ground. This cutting stimulates the development of side shoots. Subsequently, every 2 - 3 weeks, a cutting may take place, with a total of 2 - 8 cuttings possible[ 299 ]. For a once-over harvest from a direct sown crop, the plants are uprooted or cut at ground level when they are 30 - 40cm tall, 3 - 5 weeks after emergence and before the development of fruits[ 299 ]. In Nigeria, a yield of 20 - 25kg from a 10 square metre bed (25 tonnes per hectare) may be expected from 3 - 9 cuttings of 'Amugbadu' during a period of 3 - 4 months. A yield of 38 tonnes per hectare was obtained from a well-fertilized field of cultivar 'Ewondo' in the Cameroon. Farmers however, usually obtain average yields of 5 - 15 tonnes[ 299 ]. The world average jute yield is about 1.9 tonnes of raw fibre per hectare, but yields of 5 tonnes have been obtained in Bangladesh with improved cultivars grown under optimal agronomic conditions[ 299 ]. Intercropped with Vigna, jute has yielded 3,270 kilos compared to 2290 kilos when monocropped[ 269 ]. A commercially cultivated vegetable and an important vegetable in arid areas. Part of the national dish of Egypt.

Propagation

Seed - pre-soak for 24 hours in warm water and then sow in situ[ 300 ]. Seeds are often broadcast into fine seed beds at the beginning of the wet season. Mixing the small seeds with sand makes it easier to sow them evenly. Often seeds are slow to start growing. This can be overcome by soaking them in hot water. A spacing of 20-30 cm between plants is suitable.

As a vegetable, Chorchorus olitorius was eaten by the African & Middle-eastern population from ancient period. They used it in a soup or pot-herb called Molokhiya. The material that they used to make Molokhiya, was called Nalita. Nalita is the powder of the dried Corchorus olitoirus leaf. Therefore, in African & Middle-Eastern region, COrchorus olitorius is also called Nalita or Nalta Jute. Some researches have been done in Bangladesh and India that states that its leaves can work as anti-oxidents and can reduce Arsenic Contamination. The fascinating fact about Jute is that, it is the second vegetable fiber after cotton. As it can not be used in manufacturing clothing items, the fiber is also a cheap fiber. However, its fiber is recently being used as Clothing fiber in China. But, Jute fiber has some properties of wood also, because of large amount of Lignin. Therefore, Jute fiber is the finest raw material for composite industries.
