IRIDACEAE 
Sisyrinchium anceps Cav. Diss. 6 (1788) 345, t.190, fig. 2. 
S. Ocsapurga nom. nud. 
(palma—palma; pajapurgante) 
A decoction of the roots is laxative. A slight tasting of these 
roots leaves a pungency and acrimony in the mouth for more 
than six hours and may cause much discomfort. “I judge from 
this that its purgative properties are too drastic and ought to be 
used more cautiously than the Indians are wont to do.” 
Sisyrinchium luteum Bert. ex Steud. Nom., Ed. 2 (1841) 596.

Sisyrinchium purgans nom. nud. 
(ossapurga; pajapurgante) 
The natives employ the roots as a purgative, controlling the 
strong laxative effects with draughts of cold water. Since it is a 
potent laxative, it must be used with caution.
