Curculigo is a flowering plant genus in the family Hypoxidaceae, first described in 1788. It is widespread across tropical regions of Asia, Africa, Australia, and the Americas.

Curculin is a sweet protein that was discovered and isolated in 1990 from the fruit of Curculigo latifolia, a plant from Malaysia. Like miraculin, curculin exhibits taste-modifying activity; however, unlike miraculin, it also exhibits a sweet taste by itself. After consumption of curculin, water and sour solutions taste sweet. The plant is referred to locally as lembah or lumbah; English: 'weevil-wort'.
