Question 1

What is Dalbergia lanceolaria used for in ayurvedic medicine?

Accepted Answer

In Sri Lanka's ayurvedic tradition, the bark and heartwood of Dalbergia lanceolaria are associated with treatments for skin disorders, fever, and inflammatory conditions. The tree's astringent properties also lend it uses in wound-care preparations. It appears in classical compound formulations rather than typically as a stand-alone remedy.

Question 2

Where does Dalbergia lanceolaria grow in Sri Lanka?

Accepted Answer

The species is most often found in dry lowland forests and scrub habitats across Sri Lanka's north-central and north-western regions. It tolerates poor, well-drained soils and seasonal drought. Protected areas such as Wilpattu National Park harbour some of the more intact populations.

Question 3

Is Dalbergia lanceolaria a threatened species?

Accepted Answer

The broader Dalbergia genus contains several threatened species due to over-exploitation for rosewood timber. Dalbergia lanceolaria is not among the most critically assessed members, but dry-zone habitat loss in Sri Lanka and South Asia generally poses a long-term risk to the species. International CITES regulations cover the genus at a broad level.

Question 4

What part of the Dalbergia lanceolaria tree is used medicinally?

Accepted Answer

The bark and heartwood are the primary parts used in traditional preparations. Leaves may also be employed in some folk remedies. Harvesting is ideally done sustainably to avoid damaging the tree permanently, particularly given pressures on wild populations.

Question 5

What does a Dalbergia lanceolaria tree look like?

Accepted Answer

It is a medium to large deciduous tree, typically 15–25 metres tall, with rough greyish-brown bark that develops longitudinal cracks with age. The leaves are pinnately compound and the flowers are small, pale pink to white, appearing in loose clusters. The fruit is a flat pod containing one to three seeds.

Question 6

How is Dalbergia lanceolaria catalogued in Sri Lanka?

Accepted Answer

The species is formally listed in Sri Lanka's national catalogue of ayurvedic medicinal plants under the reference number LK94006401. The Department of Ayurveda maintains this catalogue as part of the government's effort to document indigenous botanical knowledge.

Question 7

Are there research studies on Dalbergia lanceolaria's medicinal properties?

Accepted Answer

Scientific research has focused more extensively on closely related Dalbergia species, identifying flavonoids, isoflavones, and stilbenes with antioxidant and anti-inflammatory activity. Whether Dalbergia lanceolaria shares an identical phytochemical profile remains an active area of inquiry, though its traditional use provides a basis for ongoing investigation.
