Medicinal Uses of Ervatamia Heyneana
In southern India, the species of Ervatamia heyneana is used medicinally as a substitute for 'Tabernaemontana divaricata' which is a closely related and more widely distributed species. The acrid, bitter root is used as a local anodyne and chewed to relieve toothache. Rubbed into a thin paste of Ervatamia heyneana with water is often taken internally as a vermicide. This paste of the plant is also applied with limejuice to clear opacity of the cornea. Charcoal is prepared from the root and the milky juice of the leaves and this is vastly used to treat opthalmia. The juice of the flowers, mixed with oil, is applied externally to relieve the burning sensation in sore eyes. The mixture of the juice of the flowers and oil is rapidly used for relief of some skin diseases. The milky juice of the leaves is used as a cooling application for wounds and it also reduce inflammation.
