Folk medicinal uses
D. supinum is said to be an excellent haemostatic and was used in Cuban hospitals during the wars of independence: its root decoction is considered to be of some value in the treatment of dysentery. Wright recorded its use among poor people as a diaphoretic in cases of colds and slight fever: he considered it of no value.
