Chukrasia tabularis, commonly known as Chickrassy or Indian Mahogany, is a large deciduous timber tree that holds a recognised place in Sri Lanka's catalogue of ayurvedic medicinal plants. Found across tropical and subtropical Asia — including Sri Lanka's lowland and mid-elevation forests — the tree is valued both for the medicinal properties attributed to its bark, leaves, and seeds, and for its dense, durable timber.
What does Chukrasia tabularis look like?
Chukrasia tabularis belongs to the family Meliaceae — the same family as mahogany and neem. It grows into a tall, straight tree that can reach 30 metres or more in maturity. The bark is rough and dark brown, exfoliating in irregular scales on older specimens. Leaves are alternate, pinnately compound, and often show a faint bronze tinge when young. Small, yellowish-white flowers appear in panicles, followed by woody capsule fruits that split open at maturity to release winged seeds adapted for wind dispersal.
Where does Chukrasia tabularis grow in Sri Lanka?
In Sri Lanka, the species occurs naturally in mixed forests across the wet and intermediate zones, typically at elevations below around 900 metres. It is associated with lowland tropical rainforest remnants and riverine forest edges. Plantations have also been established in areas where timber production is managed. Ecologically, it tends to favour well-drained soils and areas with a pronounced dry season that triggers partial leaf shedding.
The species shares its forest habitat with other native trees of medicinal and ecological importance. Sinharaja Forest Reserve, Sri Lanka's UNESCO-listed lowland rainforest, shelters a range of Meliaceae-family trees alongside a rich understorey of endemics — making it a useful reference point for understanding the ecological context in which Chukrasia tabularis thrives.
What are the traditional ayurvedic uses of Chukrasia tabularis?
In Sri Lanka's ayurvedic tradition, Chukrasia tabularis is documented primarily for the properties of its bark. The bark is considered to have astringent, antipyretic, and anti-inflammatory qualities. Traditional practitioners have used bark preparations externally for skin conditions and wound care, and internally in formulations aimed at managing fevers and gastrointestinal complaints.
The seeds, which are rich in oil, have also attracted attention in ethnobotanical literature. Leaf extracts have been explored in preliminary research for antimicrobial activity, though clinical evidence remains limited and this plant should not be used medicinally without guidance from a qualified ayurvedic physician.
- Part used: Bark, seeds, leaves
- Traditional actions: Astringent, antipyretic, anti-inflammatory (per classical texts)
- Common preparations: Decoctions, powders, topical poultices
- Family: Meliaceae
How does Chukrasia tabularis fit into Sri Lanka's broader plant medicine tradition?
Sri Lanka has one of the longest continuous records of documented plant-based medicine in Asia, with ayurvedic practice stretching back more than two millennia. The country's unique biogeographic position — a small island with high endemism and climatic diversity — has produced a particularly rich pharmacopoeia. The Sri Lanka Ayurvedic Drugs Corporation and various traditional institutions maintain catalogues of indigenous medicinal plants, of which Chukrasia tabularis is one recognised entry.
Other trees from the same island ecosystems also appear in classical ayurvedic references. Pongamia pinnata, for instance, is another native tree whose oil-rich seeds feature in traditional skin and wound treatments, illustrating the breadth of Sri Lanka's living herbal tradition.
This tradition is closely tied to the island's forest cover. Conserving patches of native forest — whether in protected reserves or on private land — directly supports the availability of wild-harvested medicinal species like Chukrasia tabularis for generations of practitioners to come.
Is Chukrasia tabularis also used as a timber tree?
Yes. Beyond its medicinal applications, the wood of Chukrasia tabularis is commercially significant. It is reddish-brown, moderately hard, and works well under tools, giving it value for furniture, cabinetry, and interior joinery. In parts of South and Southeast Asia it is traded under the name Chickrassy or White Chuglam. In Sri Lanka, native timber trees such as this are subject to forestry regulations, and harvesting from natural forest is controlled under national law.
Is scientific research being done on Chukrasia tabularis?
The species has attracted a modest but growing body of phytochemical research. Studies have isolated limonoid compounds from the bark and seeds — a class of secondary metabolites known across the Meliaceae family for biological activity. Preliminary laboratory studies have examined potential antimicrobial, antitumour, and insecticidal properties of various extracts. As with many traditional medicinal plants, peer-reviewed clinical trials in humans remain limited, and findings from laboratory or animal studies do not automatically translate into safe or effective treatments.
Researchers interested in Sri Lanka's medicinal plant biodiversity often work alongside botanical institutions such as the Royal Botanic Gardens, Peradeniya, which maintains reference collections of native and cultivated species including members of the Meliaceae family.
Can travellers encounter Chukrasia tabularis in Sri Lanka?
Visitors with an interest in ethnobotany or traditional medicine can encounter Chukrasia tabularis in several contexts. Guided forest walks in lowland wet-zone reserves occasionally include identification of medicinal trees. Ayurvedic resort programmes — particularly those in the hill country and wet zone — sometimes incorporate plant walks or herbal garden tours where species like this are pointed out by trained staff. The tree is not a spectacle in the way that a flowering species might be, but for those curious about the intersection of ecology and healing, it is a rewarding find.
If you are exploring the cultural and botanical richness of Sri Lanka's interior, combining a visit to a heritage ayurvedic garden with a stop at a site such as Horton Plains National Park gives a sense of the ecological range that underpins the island's plant traditions — from cloud-forest endemics at high elevation down to lowland medicinal trees in the wet zone.
