• The Royal Poinciana is usually grown as an ornamental tree and is widely regarded as one of the most beautiful planted tropical trees in the world.  It is often planted in streets and parks (4). This tree is fast growing and develops an umbrella-shaped crown, making it a valuable as a shade tree (4).  The wood itself is not of much value, but has been used for making fence posts, because of its resistance to water and its durability (4). The seeds are sometimes used as beads.  Research shows gum made from the dried seeds. It is used as a binder in the manufacturing of tables such as the paracetamol (4).  Tropical and subtropical locations, such as the small island of Anguilla, use the Royal Poinciana on postage stamps (4).

Its plant extract has been reported to possess anti-bacterial, anti-malarial and anti-fungal properties (6). Folk medicinal practitioners in Bangladesh use the leaves for controlling sugar level in diabetic patients (6).  This plant may possess some anti-diabetic activities (6). When tested on mice, the maximum anti-hyperglycemic activity was showed at 400 mg/kg, which was comparable to that of a standard drug, glibenclamide (10 mg/kg). The methanolic extract of leaf of Delonix regia had beneficial effects in reducing the elevated blood glucose level of hyperglycemic mice (6).
