Known as Amaranth or Pigweed and is a cosmopolitan genus. Several species are raised for grain in Asia and the Americas, it is of moderate importance in the Himalaya.
The seed and leaves was staple foodstuff of the Incas’s known as Kiwicha in the Andes today. Ancient Aztecs prepared ritual drinks and foods from it. The seeds are toasted much like popcorn and mixed with honey or molasses to make a treat called Alegría (“happiness” in Spanish) to this day in Latin America.
In West Africa Amaranth leaves are used exactly as spinach is used elsewhere.
