Is cassava leaf safe to eat?

Opinion only: Cassava leaves should never be eaten uncooked. Boiling breaks down all (or most) of the toxins (cyanogenic glucosides which become cyanide when digested) into harmless compounds. It's worth noting that only the younger, smaller cassava leaves are harvested from the plant and eaten. Cook or boil cassava leaves thoroughly, until completely tender and fragmented. Cassava isn't food one should worry about overcooking or over boiling.
