From Africa to Asia, these vibrant green leaves have been used for centuries in daily meals and traditional healing practices. If you’re curious about what makes cassava leaves so special, you’re in the right place.
What Are Cassava Leaves?
Cassava leaves come from the cassava plant, a hardy tropical shrub widely grown for its starchy roots.
