Medicinal Uses:
Pieces of branches are rubbed on stones with water to produce a paste which is applied to the face as a medicine against various ailments. Dichloromethane and methanolic extracts of Dalbergia greveana bark showed activity against gram-positive bacteria.

Other Uses:
The wood is one of the so-called rosewoods (‘Madagascar rosewood’, ‘palisander’), which are much in demand for cabinet making, furniture, marquetry and parquet flooring. It is one of the favoured woods for musical instruments, not only because of its beautiful colour and venation, but also because of its clearness of tone. It is also suitable for interior trim, joinery, ship and boat building, vehicle bodies, poles and piles, precision equipment, carvings, toys and novelties, sporting goods, handles, ladders, turnery, pattern making, veneer and plywood. The wood is used locally in Madagascar, e.g. for construction and paddles and as firewood. The Mikea people of south-western Madagascar rub pieces of branches on stones with water to produce a paste which is applied to the face as a medicine against various ailments; Dalbergia greveana is a sacred tree for these people.
