Ginger is in the family Zingiberaceae, which also includes turmericcardamom and galangal. Ginger originated in Island Southeast Asia and was likely domesticated first by the Austronesian peoples. It was transported with them throughout the Indo-Pacific during the Austronesian expansion reaching as far as Hawaii. Ginger is one of the first spices to have been exported from Asia, arriving in Europe with the spice trade, and was used by ancient Greeks and Romans. The distantly related dicots in the genus Asarum are commonly called wild ginger because of their similar taste. In 2018, world production of ginger was 2.8 million tonnes, led by India with 32% of the world total.
