This is another species of Corchorus which is extensively cultivated in most tropical countries especially Indian Bengal and Bangla Desh for the commercial jute fibres obtained from the sclerenchymatous lignified secondary phloem elements. The fibre and pith are used for the same purpose as Corchorus capsularis Linn. The plant is used in West Africa and Sudan as a pot herb. The leaves are useful in chronic cystitis, gonorrhoea and dysuria and their infusion is given as tonic and febrifuge. The seeds have purgative properties and the fruit contains ascorbic acid. (Vit. C.).
