The Erythrina Indica tree outside my house is currently in bloom and looks glorious. Erythrina Indica (Indian Coral Tree; Tamil = Kalyana Murungai) is a species of the genus Erythrina which contains approximately a hundred trees and shrubs. Erythrina is from the Greek word erythros, meaning red in allusion to the colour of the bloom and Indica to its country of origin. This tree which is commonly found throughout Tiruvannamalai District, is cultivated as a support for various climbing plants (particularly the betel leaf). As it is also an excellent nitrogen fixer, the Erythrina Indica is often planted in fields to improve yield.

The leaves of this tree fall once a year and is followed by the blooming of beautiful scarlet blossoms. This tree will now attract a multitude of bird visitors to its wonderful coloured leaves. Salim Ali in his, “the Book of Indian Birds,” positively identifies the Erythrina Indica as a tree with its seeds and brightly coloured leaves, that is strongly favoured by birds. When in bloom, the tree's scarlet red flowers attracts; crows, mynas, babblers, starlings and green parrots to feed upon the nectar inside the flower and thereby pollinate the tree.

This highly valued ornamental tree has been described as one of the gems of the floral world. It grows along the coastal and inland districts in deciduous forests. The Indian Coral Tree can reach sixty feet height and spread twenty feet. It has stout branches armed with black tiger's claw spine and curved prickles on its long leaf stalks. Though the timber of the tree is light and soft, it is durable when heavy woods are deemed unsuitable.

All Erythrina species contain 'Erythrina alkaloids', which include erythrane, erythroidine and coralline. These alkaloids are found in the whole plant, but especially in the seeds. In small doses the seeds cause sedation, relaxation (especially of the muscles) and if taken before bedtime a long and deep sleep. In higher doses (more than a quarter seed) the effects become exponentially stronger and unpredictable. The seeds are usually too potent for accurate dosing, but dried flowers or dried leaves are suitable for teas or smoking mixes.

The leaves are laxative, diuretic, anthelmintic and are able to induce milk secretion in a new mother. The trees’ leaves are also employed in the treatment of inflammatory swellings of lymph nodes, especially in the groins and armpits. The bark of the Erythrina Indica is used for fever, hepatosis, malaria, rheumatism, toothache, the treatment of epilepsy, and boils and fractures. One can also eat new leaves in curries and the adult leaves can make very useful cattle fodder.
A strong scented dye can be obtained from the flowers of this tree. Mythology reports that the God, Lord Krishna stole the flowers of the Coral Tree from Lord Indra’s garden.
