This species has been known generally as C. eynophallophora L.^ The root has 

 a flavor resembling that of horse-radish. In the West Indies an infusion of it 

 has been used for dropsy and as an emmenagogue and a decoction of the leaves 

 for cutaneous diseases. Sedative and antispasmodic properties are attributed 

 to the fruit, and diuretic and emmenagogue properties to the bark. For an illus- 

 tration of a fruiting branch see Contr. U. S. Nat. Herb. 8: pi. 23.
