| There are 
        many plants/tubers called yuca or yucca - some are safe to eat, some aren't 
        (see chart below). The following information was 
        culled from a number of sources, including:  Plants 
        for a FutureThe

     UsesPeople in Hispanic countries 
        use cassavas (also called manioc, mandioca, yucca, yuca, yucca root, yuca 
        root, Brazilian arrowroot) much like those of us in the U.S. use potatoes. 
        Some of the tubers are sweet even when eaten raw; others are bitter. In 
        the case of the Agavaceae, most times the bitterness seems to be in the 
        skin, so peeling the tuber before using or cooking should greatly reduce 
        the bitterness (which is due to its prussic acid content). Fresh tubers 
        can be hard to peel; nuking it for a minute or so may make it easier, 
        just as it does with winter squash. The fresh tubers don't have a long 
        shelf life, so use within a couple of days of purchase.
  The flowers, 
        especially the young ones of must Yucca species are tender and sweet when 
        eaten raw. You can even stuff them with a savory vegetable/bread crumb 
        stuffing and steam or bake them.    Yucca

             |   Saponins:The roots contain saponins which are quite toxic to people. However, they 
        are poorly absorbed by the body, and so tend to pass straight through, 
        and they are destroyed by prolonged heat, such as slow baking in an oven. 
        Saponins are much more toxic to some creatures, such as fish, and hunting 
        tribes have traditionally put large quantities of them in streams, lakes, 
        etc., in order to stupefy or kill the fish.
