Scientific classification
Kingdom: Plantae
Clade: Tracheophytes
Clade: Angiosperms
Clade: Eudicots
Clade: Rosids
Order: Fabales
Family: Fabaceae
Genus: Dalbergia
Species:
D. lanceolaria
Binomial name
Dalbergia lanceolaria
Synonyms[1]
  • Amerimnon lanceolarium (L.f.) Kuntze
  • Dalbergia arborea B.Heyne
  • Dalbergia frondosa DC.

The bark of the tree is traditionally used as an analgesic and anti-diarrhoeal.[5] The apiose isoflavone compound lanceolarin is found in its root bark.[6]

Because it produces new stems (ramets), it is recommended for reforestation projects on degraded land where seeds are unlikely to grow successfully.[7]
