Ginger originated from Maritime Southeast Asia. It is a true cultigen and does not exist in its wild state. The most ancient evidence of its domestication is among the Austronesian peoples where it was among several species of ginger cultivated and exploited since ancient times. They cultivated other gingers including turmeric (Curcuma longa), white turmeric (Curcuma zedoaria), and bitter ginger (Zingiber zerumbet). The rhizomes and the leaves were used to flavour food or eaten directly. The leaves were also used to weave mats. Aside from these uses, ginger had religious significance among Austronesians, being used in rituals for healing and for asking protection from spirits. It was also used in the blessing of Austronesian ships.
