Costus is a genus of herbaceous perennial plants in the family Costaceae, erected by Linnaeus in 1753. [2] [3] It is widespread through tropical and subtropical regions of Asia, Africa, and the Americas. [1] [4] [5]
Costus is often characterized and distinguished from relatives such as Zingiber (true ginger) by its spiraling stems. The genus as a whole is thus often called spiral gingers, but this can also refer to C. barbatus specifically.[ citation needed ]
Costus spectabilis is the floral emblem of Nigeria; its flowers are represented (erroneously in red instead of yellow color) on its coat of arms.[ citation needed ] It is important not to confuse Costus scaber, C. spectabilis etc. with the herb known by the common name "costus".
In Trinidad and Tobago, a mix of Costus scaber juice and crushed Renealmia alpinia berries is used to treat dogs bitten by snakes. [6] [ failed verification ]
