Safety Overview
1.Red Sandalwood — Overview
Pterocarpus santalinus, widely recognized as Red Sandalwood or Red Sanders, is a distinctive medium-sized deciduous tree belonging to the Fabaceae family. It typically attains a height of 10 to 15 meters, characterized by a straight trunk and a dense, rounded canopy. The foliage comprises alternately arranged, compound leaves, each bearing 5-7 ovate to obovate leaflets that measure approximately 5-10 cm in length.
These leaflets exhibit a lustrous dark green on their upper surface and a noticeably paler underside. The bark of Pterocarpus santalinus is rough and textured, ranging in color from dark brown to grayish-black, often deeply fissured vertically, revealing a reddish inner layer. Its small, yellowish to pinkish flowers are borne in axillary racemes or panicles, typically blooming during the summer months and adding a delicate beauty to the tree.
Following flowering, the tree produces flat, orbicular to broadly ovate pods, usually 5-10 cm long, which are distinctive for their single-seeded, winged structure, facilitating wind and water dispersal. Native to the dry deciduous forest ecosystems of South Asia, particularly endemic to the Eastern Ghats region of southern India, Pterocarpus santalinus thrives in arid to semi-arid climates, preferring well-drained, sandy-loam soils and abundant full sunlight. This species is highly valued for its dense, rich red heartwood, which is not only prized for its timber but also for its profound chemical composition that underpins its extensive traditional and modern medicinal applications.
