Cassava tubers can not stand save even placed in the refrigerator. Symptoms of damage is marked by the release of a dark blue color due to formation of cyanide which is poisonous to humans.

Cassava tuber is the source of energy-rich carbohydrates but very poor in protein. A good source of protein actually present in cassava leaves because they contain the amino acid methionine.

Modern forms of which have been cultivated species can be found growing wild in southern Brazil. Although the wild Manihot species there are many, all varieties of M. esculenta can be cultivated.
