Capsules 3-6.5 cm long, linear, cylindric erect, beaked, glabrous, 10-ribbed, 5-valved; valves with transverse partitions between the seeds. Seeds trigonous, black
Habit / Habitat
The habitat range of the Nalta jute is very wide ranging from warm temperate thorn through tropical desert to wet forest life zones. For cultivation purposes it prefers a very fertile soil and a hot humid climate. It is reported to tolerate an annual precipitation between 40 and 429mm, annual average temperature range of 16.8 to 27.5°C and a pH in the range of 4.5 to 8.2 .
1) Availability of the plant species in India: Native to Indian subcontinent
2) Global distribution: It is being cultivated in warm regions such as Egypt, southern United States, West Africa, Sudan, Turkey, Iran, Thailand, Java, Paraguay, Brazil, Argentina, Mexico and so on.
World wide use: Leaves, young fruits
Used by tribal community in Jawhar: Leaves
Method of consumption
Young leaves are boiled and cooked as vegetable.
- Young leaves are added to salads whilst older leaves are cooked as a pot-herb .
- The dried leaves can be used as a thickener in soups or as tea .

- As per a study, ethanolic extract of C. olitorius have gastroprotective property (i.e. it protects the gastric mucosa of aggressive or irritating agents) against ethanol-induced gastric ulcers in adult Sprague Dawley rats .
- Leaves of Corchorus olitorius L. possess six phenolic anti-oxidative compounds. Out of the six, 5-caffeoylquinic acid was a predominant phenolic antioxidant in C. olitorius leaves . Phenolic anti-oxidants have valuable anti-ageing and anti-inflammatory benefits. This property supports its consumption as green tea or soup.
- Aqueous extracts of stems and leaves of C. olitorius have some toxic potentialities on the blood chemistry of albino rats.
- Seeds have been reported to possess estrogenic activity as well as high content of hydrogen cyanide and several cardiac glycosides.
