Costus spicatus, also known as spiked spiralflag ginger or Indian head ginger, is a species of herbaceous plant in the Costaceae family (also sometimes placed in Zingiberaceae).[1]
Distribution
Costus spicatus is native to the Caribbean (including Dominica, Guadeloupe, Hispaniola, Martinique, and Puerto Rico).[1][2][3]
Description
Costus spicatus leaves grow to a length of approximately 1 ft (30 cm) and a width of approximately 4 in (10 cm). It produces a short red cone, from which red-orange flowers emerge one at a time.[4] In botanical literature, Costus woodsonii has often been misidentified as Costus spicatus.[5]
Cultivation
Costus spicatus will grow in full sun if it is kept moist. It reaches a maximum height of about 6 to 7 feet (1.8 to 2.1 m).[4]
Ecology
Costus spicatus can develop a symbiotic partnership with certain species of ants (often only a single species of ant will be compatible). The ants are provided with a food source (nectar in C. spicatus flowers) as well as a place to construct a nest. In turn, the ants protect developing seeds from herbivorous insects.[4]
Medicinal use
In Dominican folk medicine, an herbal tea made from the leaves of C. spicatus is used for diabetes (hyperglycemia). However, a 2009 study concluded that C. spicatus tea "...had no efficacy in the treatment of obesity-induced hyperglycemia."[6]
