Rosy Trumpet Tree is highly regarded as an ornamental tree mainly due to its spectacular rose blossoms during the spring. As a result, the tree is nominated as the national tree of El Salvador, vernacularly known as Maquilíshuat. The tree is versatile in America for multiple uses. In the Northern Coast of Colombia, people often use its bark extract for tackling the skin diseases induced by fungi and yeast. In addition, some studies reveal that the methanolic extracts of Rosy Trumpet Tree are anti-ulcerogenic, antimycobacterial and hepatoprotective; they are potential for drug development. In Mesoamerica, the wood is demanded for making furniture, ships and other constructions . |
