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.

In traditional medicine a bark decoction is used to treat liver complaints, diabetes, hernia, skin diseases, constipation, fever and rheumatism. The bark is also applied as an expectorant, emetic and vermifuge, as well as to treat epilepsy, smallpox, oedema, sores and abscesses[299 ]. Several isoflavones have been isolated from the heartwood, and several alkaloids, including guanidine alkaloids, from bark and seeds[299 ].

Other Uses

Fencing  Furniture  Insecticide  Pioneer  Wood

Agroforestry Uses: Flowering trees provide nectar to honey bees[299 ]. Stem cuttings are planted as a live fence[299 ]. The tree is used as a pioneer, being planted for the reforestation of formerly cultivated land[299 ]. Other Uses The bark has insecticidal properties[299 ]. The seeds contain about 35% oil, though no uses are mentioned[299 ]. The heartwood is yellow when freshly sawn but darkens on exposure to dark brown or black-brown, with black streaks; it is sharply demarcated from the 2 - 5cm wide band of pale yellow sapwood. The grain is straight, texture medium to coarse. The wood is heavy, hard, elastic and very durable, being resistant to fungal, dry-wood borer and termite attacks and moderately resistant to marine borers, but the sapwood is susceptible to attack by powder-post beetles. It has a tendency to split. It saws and works well, but force is required and sawteeth and cutting tools may blunt rapidly; stellite-tipped sawteeth and tungsten-carbide tipped cutting tools are recommended; it is difficult to polish and the use of a finishing wax is recommended; pre-boring before nailing and screwing is needed; it slices well and can also be rotary cut, but intensive steaming is then needed. The gluing and varnishing properties are poor due to the presence of resin cells, but the use of a filler improves the results considerably. The wood is commonly used for heavy flooring, interior and exterior joinery, interior and exterior panelling, cabinet work, furniture, carving, turnery and sliced veneer. It is also suitable for heavy construction, mine props, vehicle bodies, implements, sporting goods, toys, novelties, boxes, crates and railway sleepers. It is in high demand for decorative furniture and parquet flooring. It is also used for high-quality musical instruments, especially guitars; it is said to give a good and strong tone. It is popular for the production of sculptures, masks and drums[299 , 316 ].

Cultivation details

The wood does not float and therefore cannot be transported by river[299 ]. This species has a symbiotic relationship with certain soil bacteria; these bacteria form nodules on the roots and fix atmospheric nitrogen. Some of this nitrogen is utilized by the growing plant but some can also be used by other plants growing nearby[755 ].
