[2]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.

[3][4] Curculin is a sweet protein that was discovered and isolated in 1990 from the fruit of Curculigo latifolia,[5] a plant from Malaysia.

After consumption of curculin, water and sour solutions taste sweet.

The plant is referred to locally as lembah or lumbah; English: 'weevil-wort'.
