The hairs of the stems penetrate the skin readily and cause irritation. 

 The crushed leaves have been applied in the West Indies to the skin for the 

 purpose of removing chiggers ("niguas"), and are said to be effective. The 

 decoction of tlie plant is sometimes used as a wash to cure cutaneous diseases 

 and ulcers of the mouth. The roots are reported to have diuretic properties.
