It belongs to the ginger family, but does not taste as hot as ginger, but rather mildly spicy and slightly bitter. It grows in Southeast Asia and India and grows to about one meter high. Like ginger, curcuma forms tuber-like parts called rhizomes. Curcuma contains the plant substance curcumin, which gives the plant its yellow-orange colour.
