  • Calophyllum inophyllum also known as Sultan Champa is a beautiful large evergreen tree native to southern coastal India, East Africa, Malaysia and Australia. It is a low-branching and slow-growing tree with a broad and irregular crown. It usually reaches 8 to 20 m in height. The tree supports a dense canopy of glossy, elliptical leaves. The very fragrant white flowers are 25 mm across and occur in racemose or paniculate inflorescences consisting of 4 to 15 flowers. The flowers have snow-white petals with a thick center of yellow stamens. The fragrant flowers have been prized as an adornment and as a perfume. The fruit (the ballnut) is a round, green drupe reaching 2 to 4 cm in diameter and having a single large seed. When ripe, the fruit is wrinkled and its color varies from yellow to brownish-red. This tree often grows in coastal regions as well as nearby lowland forests. However it has also been cultivated successfully in inland areas at moderate altitudes.
    Besides being a popular ornamental plant, its wood is hard and strong and has been used in construction or boatbuilding. Traditional Pacific Islanders used Calophyllum wood to construct the keel of their canoes while the boat sides were made from breadfruit (Artocarpus altilis) wood.
    The seeds yield a thick, dark green tamanu oil for medicinal use or hair grease. Active ingredients in the oil are believed to regenerate tissue, so is sought after by cosmetics manufacturers as an ingredient in skin cremes. The nuts should be well dried before cracking, after which the oil-laden kernel should be further dried. The first neoflavone isolated in 1951 from natural sources was calophyllolide from Calophyllum inophyllum seeds.
    The leaves are also used for skin care in Papua New Guinea, New Caledonia, and Samoa. In Fiji and Lingua the leaves are also soaked in water and used for eye inflammations.
    In Cambodia, the leaves are inhaled as a treatment for migraines and vertigo.
    The bark can be used as a treatment for disease-affected plants. The Mavilan, a Tulu-speaking tribe in north Kerala in India, use the Calophyllum inophyllum bark to make a powder that they mix with water and apply it on plants affected by a type of plant disease caused by water that they call neeru vembu.
    The sap of the tree is poisonous and is used to make poison arrows in Samoa. The mature fruit is poisonous enough to use as rat bait.
