Cultivation Details

Succeeds in tropical and subtropical zones at elevations up to 1,800 metres. Grows best in areas where the mean annual temperature falls within the range 32 - 40°c, but can tolerate 8 - 47°c[]. Plants are killed at temperatures below -2.5°c[]. Prefers a mean annual rainfall of 1,200 - 2,000mm, tolerating 600 - 3,800mm[].
Grows best in a sunny position[]. Succeeds in most soils of moderate fertility, tolerating poor soils[]. Prefers a pH in the range 5 - 6.5, but tolerates 4.5 - 8[].
In its more common, dry woodland environment, the tree is usually small and somewhat ungainly - in moister conditions, however, it can become a handsome, spreading tree[]. The valuable heartwood is generally only formed in sufficient quantity from trees grown in moister conditions[].
The tree is resistant to fire[].
A dioecious species, both male and female forms need to be grown if seed is required.

Edible Uses

Young leaves and sprouts - raw or cooked[]. Eaten as a vegetable[, ]. Eaten as a lalab (a vegetable salad served with sambal) with rice[].

The gum obtained from the trunk is often used in confectionery[].

The powdered bark is used as a flavouring[].

Medicinal

Agroforestry Uses:

The plant can be grown as a hedge[]. It is easily propagated by cuttings and so can be grown as a living fence[].

Other Uses

The bark contains tannins[, , ]. It is used for the impregnation of fishnets[].

A soluble resin, called 'Jingan gum' is obtained from the stems[]. It is used for calico printing; as a size for paper; for mixing with lime when whitewashing; protecting nets etc[, ]. It is obtained by making shallow, short cuts all over the bark[]. Especially after injuries of the bark and trimmings, masses of glassy-white exudate of hardening gum appear - which may give leafless trees an eerie appearance[]. A good quality gum[]. The gum is of inferior quality[].

The bark yields a coarse cordage fibre[].

The heartwood is light red when freshly cut, turning reddish-brown on exposure[]. The wood is moderately hard, close-grained[]. It is used for spear shafts, scabbards, wheel-spokes, oil presses, grain pounders etc[].
The wood is used for fuel[].

Propagation

Seed - it only has a short viability and so needs to be sown as soon as possible[].
Cuttings - very easy, even large branches usually root[].
