Southeast Asia and Australasia, and the species is now cultivated throughout the tropics and widely naturalized.[1]
Among some 100 names for the fruit across different regions are the more common English names, great morinda, Indian mulberry, noni, beach mulberry, and cheese fruit.[2]

Growing habitats[edit]
Morinda citrifolia grows in shady forests, as well as on open rocky or sandy shores.[3] It reaches maturity in about 18 months, then yields between 4 and 8 kg (8.8 and 17.6 lb) of fruit every month throughout the year. It is tolerant of saline soils, drought conditions, and secondary soils. It is therefore found in a wide variety of habitats: volcanic terrains, lava-strewn coasts, and clearings or limestone outcrops, as well as in coralline atolls.[3] It can grow up to 9 m (30 ft) tall, and has large, simple, dark green, shiny and deeply veined leaves.
The plant bears flowers and fruits all year round. The fruit is a multiple fruit that has a pungent odour when ripening, and is hence also known as cheese fruit or even vomit fruit. It is oval in shape and reaches 10 18 centimetres (3.9 7.1 in) size. At first green, the fruit turns yellow then almost white as it ripens. It contains many seeds.[3]
Morinda citrifolia is especially attractive to weaver ants, which make nests from the leaves of the tree.[3] These ants protect the plant from some plant-parasitic insects. The smell of the fruit also attracts fruit bats, which aid in dispersing the seeds. A type of fruit fly, Drosophila sechellia, feeds exclusively on these fruits.[4]
Food[edit]
A variety of beverages (juice drinks), powders (from dried ripe or unripe fruits), cosmetic products (lotions, soaps), oil (from seeds), leaf powders (for encapsulation or pills) have been introduced into the consumer market.[5]
Noni is sometimes called starvation fruit.[5] Despite its strong smell and bitter taste, the fruit is nevertheless eaten as a famine food[6] and, in some Pacific islands, even a staple food, either raw or cooked.[7] Southeast Asians and Australian Aborigines consume the fruit raw with salt or cook it with curry.[8] The seeds are edible when roasted.
In Thai cuisine, the leaves (known as bai-yo) are used as a green vegetable and are the main ingredient of kaeng bai yo in which the leaves are cooked with coconut milk. The fruit (luk-yo) is added as a salad ingredient to some versions of somtam.
Traditional medicine[edit]
Green fruit, leaves, and root/rhizomes might have been used in Polynesian cultures as a general tonic, in addition to its traditional place in Polynesian culture as a famine food.[5]
In traditional Chinese medicine, the roots, known as ba ji tian, have been used for abdominal pain, impotence, and menstrual disorders.[9]Although Morinda is considered to have biological properties in traditional medicine, there is no confirmed evidence of clinical efficacy for any intended use.[10]
Dyes[edit]
Morinda bark produces a brownish-purplish dye that may be used for making batik. In Hawaii, yellowish dye is extracted from its roots to dye cloth.[11]
Nutrients and phytochemicals[edit]
Morinda citrifolia fruit powder contains carbohydrates and dietary fibre in moderate amounts.[12] These macronutrients evidently reside in the fruit pulp, as M. citrifolia juice has sparse nutrient content.[13] The main micronutrients of M. citrifolia pulp powder include vitamin C, niacin(vitamin B3), iron and potassium.[12] Vitamin A, calcium and sodium are present in moderate amounts. When M. citrifolia juice alone is analyzed and compared to pulp powder, only vitamin C is retained[13] in an amount (34 mg per 100 gram juice) that is 64% of the content of a raw navel orange (53 mg per 100 g or 89% of the Daily Value).[14] Sodium levels in M. citrifolia juice (about 3% of Dietary Reference Intake, DRI)[12] are high compared to an orange, and potassium content is moderate.[14]
Morinda citrifolia fruit contains a number of phytochemicals, including lignans, oligo- and polysaccharides, flavonoids, iridoids, fatty acids, scopoletin, catechin, beta-sitosterol, damnacanthal, and alkaloids.[15] Although these substances have been studied for bioactivity, current research is insufficient to conclude anything about their effects on human health.[1] These phytochemicals are not unique to M. citrifolia, as they exist in various plants.[11]
