In particular, its bark, including the resin it produces, are used against various pulmonary conditions, kidney problems, stomach ulcers, haemoptysis, uterine bleeding, colitis, and for post-natal vaginal washes. Recent studies have shown that Urunday have potential as treatment of nerve-degenerative diseases like Parkinson?s disease. The wood is very heavy, durable, and strong. It is a source of muiracatiara timber. Portuguese common names: aroeira-do-sert?o, urunde?va, aroeira preta, urinde?va, arinde?va.

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.

The bark, and the resin obtained from it, are balsamic and haemostatic. They are used in the treatment of pulmonary complaints, kidney problems, haemoptysis, metrorrhagia, for post-natal vaginal washes, stomach ulcers and colitis[ 739 ]. The resin is also tonic[ 739 ]. Research has shown that both aqueous and alcohol extracts of the bark strongly inhibit gastric ulceration[ 739 ]. Extracts of the bark have been shown to exert a neuro-protective effect and could provide benefits, along with other therapies, in neurodegenerative injuries, such as Parkinson?s disease[ 744 ].
Other Uses
Other uses rating: Medium (3/5). Other Uses The cherry-red to dark-brownish red wood is very heavy, very durable and strong[ 46 , 419 ]. It is an excellent timber for external work, being used for railroad ties, telegraph posts, bridge timbers, posts and piles[ 46 , 419 ]. The wood is a source of muiracatiara timber. We have no more specific information, but a general description of muiracatiara timber is as follows:- The heartwood is pinkish-brown to yellow-brown, becoming red-brown to dark brown with very irregularly spaced black-brown veins; it is clearly demarcated from the 4 - 10cm wide band of sapwood. The texture is fine; the grain straight or interlocked. The wood is heavy, hard and very durable, being resistant to fungi, dry wood borers and termites. It seasons normally with little risk of checking or distortion; once dry it is poorly stable in service. It has a fairly high blunting effect upon toold, stellite-tipped and tungsten carbide tools are recommended; nailing and screwing are good, but pre-boring is necessary; gluing is poor. The wood has a wide range of applications, being used in cabinet making for high class furniture, for flooring, turnery, interior and exterior joinery, heavy carpentry, tool handles, musical instruments, carving etc[ 848 ].
Cultivation details
A plant of the warm temperate zone to the tropics, where it can succeed in semi-arid to moist regions with 2,000mm of rain per year[ 419 ]. Prefers a sunny position in a well-drained soil. In different silvicultural trials, trees of 3 years have attained a height of 1.7 metres; trees of 5 years have attained a height of 5.11 metres; and trees of 9 years have attained a height of 9.6 metres with a bole diameter of 97mm[ 402 ].
Seed - it does not need pre-treatment and is best sown as soon as it is ripe in a semi-shaded nursery bed. A germination rate of more than 80% is normally achieved within 8 - 18 days[ 419 ]. The seedlings grow away quickly.
