Morinda citrifolia is a fruit-bearing tree in the coffee family, Rubiaceae, native to Southeast Asia and Australasia, which was spread across the Pacific by Polynesian sailors.

They are initially green, transitioning through pale yellow to white or grey, and when ripe they emit a pungent odour similar to blue cheese.

[10][12]: 182 [13] Morinda citrifolia grows in shady forests and on open rocky or sandy shores.

It can be found in various environments including volcanic terrains and clearings or limestone outcrops, as well as in coral atolls.

[14] It can grow up to 9 m (30 ft) tall and has large, simple, dark green, shiny, and deeply veined leaves.

Morinda citrifolia is attractive to weaver ants, which make their nests by using the leaves of this tree.

[17] Southeast Asians and Aboriginal Australians consume fresh fruit with salt or cook it with curry.

[13] Although Morinda is considered to have biological properties in traditional medicine, there is no confirmed evidence of clinical efficacy for any intended use.

[20] In 2018, a Hawaiian manufacturer of food and skincare products based on this fruit was issued an FDA warning letter for marketing unapproved drugs and making false health claims in violation of the US Food, Drug, and Cosmetic Act.

[11][13] Yolngu artists at Bula'Bula Arts in Ramingining, in central Arnhem Land in the Northern Territory, Australia, use the roots and bark of djundom, as it is known to them, to dye the fibres of pandanus to create a wide variety of artifacts.

[26] Sodium levels in M. citrifolia juice (about 3% of Dietary Reference Intake, DRI)[24] are high compared to an orange, while potassium content is moderate.
