INDIAN CORAL TREE: HISTORY, USES AND HEALTH BENEFITS OF THE INDIAN CORAL TREE
The Indian coral tree is as its name suggests native to the Indian subcontinent, and its range extends throughout
South-east Asia to . It was introduced in ancient times to the Pacific islands and to parts of Malaysia Africa. The Indian coral tree is a member of the Leguminoseae or Fabaceae family of plants making it a relative of dhak, the pongam tree, ashoka (Saraca indica),the monkey pod tree, jhand, lentils, indigo, the butterfly pea, chickpeas, soya beans and lupins to name but a few.
The tree is useful as a nitrogen fixer and helps poor soil increase its fertility. It is panted as an ornamental and a shade tree, and used for this last purpose in coffee and cacao plantations. It is also used as a trellis for vines and climbing plants and is used to support the betel nut (paan) vine, black pepper plants, as well as vanilla and yams.
The bark of this tree is paper-thin and can be yellow through to brown, and the seed pods contain between five and twelve seeds. The tree can grow to around sixty feet although they rarely grow to heights of more than fifty feet (fifteen metres). Some people in
use the seeds, a kidney-shaped bean that looks rather like a red kidney bean, as food, but mostly they are not eaten. The seeds contain oil and it has been suggested that this could be a source of biofuel in the future. The pods grow to between six inches and a foot. The trees have thorns on their branches, but nonetheless the pods are used for fodder. However this means that they make useful living fences to demarcate boundaries and deter animals. Bangladesh
The bark and leaves of this tree are mainly the parts used in Ayurvedic medicine in the Indian subcontinent, with the juice from the leaves being put into ears to stop earache. The paste made from the tree parts is used for rheumatism and joint pains, applied to the affected areas, and it is also used for wounds as it has antiseptic properties, and for inflammation, including for eye problems. A powder is made to aid digestion, as an aphrodisiac and for erectile dysfunctions. It is also used to get rid of intestinal worms, for blood purification, to regulate menstruation, for infections of the urinary tract such as cystitis, obesity, fevers and externally for skin problems.
In a 2002 study conducted by Tanaka H. et al. the isoflavonoids were found to have antibacterial properties. More studies are underway to discover whether the traditional medicinal uses of this tree have scientific bases.
