Description

The Sal tree, also sarai and other names, is a species of tree in the family Dipterocarpaceae. This tree is native to the Indian subcontinent, ranging south of the Himalaya, from Myanmar in the east to Nepal, India and Bangladesh. In India, it extends from Assam, Bengal, Odisha and Jharkhand west to the Shivalik Hills in Haryana, east of the Yamuna. The range also extends through the Eastern Ghats and to the eastern Vindhya and Satpura ranges of central India. It is often the dominant tree in the forests where it occurs.

Characteristics:

Sal is moderate to slow growing tree, which can grow up to 30-35 m tall, with a trunk diameter of up to 2-2.5 m. The bark of the young tree is smooth with a few long deep and vertical furrows. The leaves are ovate-oblong, 10-25 cm long and 5-15 cm broad. In wetter areas, it is evergreen; in drier areas, it is dry-season deciduous, shedding most of the leaves in between February to April, leafing out again in April and May. The sal flowers, whitish in color, appear in early summer. These are borne in raceme-like panicles in leaf axils, covered with white pubescence. In Buddhist tradition, it is said that Guatama Buddha was born under the branches of this tree while his mother was en route to birth him in his grandfather's kingdom. Sal is one of the most important sources of hardwood timber in India, with hard, coarse-grained wood that is light in colour when freshly cut, and becoming dark brown with exposure. The wood is resinous and durable, and is sought after for construction, although not well suited to planing and polishing. Sal trees are found from Burma in the East, to Assam, Bengal, Nepal, the Deccan Plateau, going up to the foothills of the Shivaliks on the left bank of the Yamuna river. Flowering: April-May.

Medicinal Uses:

Sal is one of the most important sources of hardwood timber in India, with hard, coarse-grained wood that is light in colour when freshly cut, but becomes dark brown with exposure. The wood is resinous and durable, and is sought-after for construction, although not well suited to planing and polishing. The wood is especially suitable for constructing frames for doors and windows. The dry leaves of sal are a major source for the production of leaf plates called as patravali and leaf bowls in northern and eastern India, also used as leaf plates to serve food in Karnataka Canara (Dakshina Kannada, Gokarna) regions of India. The leaves are also used fresh to serve ready made paan(betelnut preparations) and small snacks such as boiled black grams, gol gappa, etc. The used leaves/plates are readily eaten by goats and cattle. The tree has therefore protected northern India from a flood of styrofoam and plastic plates that would have caused tremendous pollution. In Nepal, its leaves are used to make local plates and vessels called "tapari", "doona" and "bogata" in which rice and curry is served. However, the use of such "natural" tools have sharply declined during last decade.
