This plant is well known in Mexico and nearly throughout Central America. 

 The leaves are placed in hot water, which at first assumes a dingy blackish color 

 but later becomes dark blue. This solution is employed by laundresses for 

 whitening clothes, in the same manner as indigo. The plant was employed for- 

 merly in Mexico also as a dye. It is used as a remedy for dysentery, fevers, 

 gonorrhoea, and other affections.
