About

Pongamia pinnata is a species of tree in the pea family Fabaceae, native to eastern and tropical Asia, Australia, and the Pacific islands. It is often known by the synonym Millettia pinnata. Its common names include Indian beech, Karanja, and Pongame oiltree.

Where it grows

The species is naturally distributed in tropical and temperate Asia, from Pakistan to Japan to Thailand and Malesia, including Sri Lanka, as well as northern and northeastern Australia and some Pacific islands;

Uses

Pongamia pinnata is well-adapted to arid zones, and has many traditional uses. It is often used for landscaping as a windbreak or for shade due to the large canopy and showy, fragrant flowers. The flowers are used by gardeners as compost for plants. The bark may be used to make twine or rope, and it also yields a black gum that has historically been used to treat wounds caused by poisonous fish. The wood is said to be beautifully grained, but splits easily when sawn, thus relegating it to firewood, posts, and tool handles. The tree's deep taproot and drought tolerance makes this tree ideal for controlling soil erosion and binding sand dunes. Rumphius writes the Malaparius (from Moluccan malapari) bark can be used to neutralise eeltail catfish venom, Seram Timur and Banda peoples infuse it with garlic, massoy and clover to treat beri-beri.
