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. [2] The species is now cultivated throughout the tropics and widely naturalised. [3] There are over 100 names for this fruit across different regions, including great morinda, Indian mulberry, noni, beach mulberry, vomit fruit, awl tree, and rotten cheese fruit. [4]
The pungent odour of the fresh fruit has made it a famine food in most regions, but it remains a staple food among some cultures and is used in traditional medicine. In the consumer market, dietary supplements are sold in various formats, such as capsules and juices.
Morinda citrifolia is a shrub or small tree up to 6 m tall, with grey-brown bark. The twigs are more or less square in cross-section and often fleshy. Stipules are present, very broad and obtuse at the apex, measuring up to 2 cm wide and long. The large glabrous leaves are arranged in opposite pairs on the twigs, reaching up to 25 cm long by 13 cm wide. They are elliptic to ovate in shape and have 6–9 pairs of lateral veins. Domatia are usually present as dense tufts of hairs in the junctions of the lateral veins with the midrib. [8] [9] [10] [11] : 182
The inflorescences are dense heads of flowers produced at the apex of the branch. They are leaf-opposed, replacing one leaf in the pair. There may be up to 90–100 flowers in the head, but only a few open at a time. The flowers are white and tubular with five lobes, measuring about 15 cm long and across. [8] [9] [10] [11] : 182
The fruit is a multiple fruit consisting of fused drupes, each containing four seeds. They are initially green, transitioning through pale yellow to white or grey, and when ripe they emit a pungent odour similar to blue cheese. They are irregularly ellipsoid or ovoid, and may reach up to 9x6 cm. [8] [9] [10] [11] : 182
The plants flower and fruit throughout the year. It is common to see flowers and fruit in varying stages of development on a plant at any given time. [9] [11] : 182 [12]
Morinda citrifolia grows in shady forests and on open rocky or sandy shores. [13] It takes 18 months for the plant to mature, and yields 4 and 8 kg (8.8 and 17.6 lb) of fruit per month throughout the year. It is tolerant of saline soils, drought conditions, and secondary soils. It can be found in various environments including volcanic terrains and clearings or limestone outcrops, as well as in coral atolls. [13] 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. [13] 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. Drosophila sechellia , a type of fruit fly endemic to the Seychelles, feeds exclusively on these fruits. [14]
A variety of beverages (juice drinks), powders (from dried ripe or unripe fruits), cosmetic products (lotions, soaps), oil (from seeds), and leaf powders (for encapsulation or pills) have been introduced into the consumer market. [12]
Indigenous peoples used the fruit as emergency food during famines. [12] Therefore, it is also called "starvation fruit". Despite its strong smell and bitter taste, the fruit was nevertheless eaten as a famine food, [15] and, in some Pacific Islands, even as a staple food, either raw or cooked. [16] Southeast Asians and Aboriginal Australians consume fresh fruit with salt or cook it with curry. [17] The seeds are edible when roasted. In Thai cuisine, the leaves known as bai-yo are used as a leaf vegetable and are the main ingredient of Kaeng bai-yo, cooked with coconut milk. The fruit luk-yo is added as a salad ingredient to some versions of green papaya salad.
In Cambodia, the leaves are an essential part of the national dish fish amok. [18]
Green fruit, leaves, and root or 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. [12] Although Morinda is considered to have biological properties in traditional medicine, there is no confirmed evidence of clinical efficacy for any intended use. [19] 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. [20]
The fruit has traditionally been used by Austronesian peoples mainly for producing dyes. It was carried into the Pacific Islands as canoe plants by Austronesian voyagers. 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. [10] [12] 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. [21]
Applying a mordant to the fabric before dyeing is necessary when using extracts of this plant as a dye. This process can be labor-intensive if the goal is to achieve shades and hues with the morinda dye. [22]
Morinda citrifolia fruit powder contains carbohydrates and dietary fibre in moderate amounts. [23] These macronutrients reside in the fruit pulp, as M. citrifolia juice has sparse nutrient content. [24] The main micronutrients of M. citrifolia pulp powder include vitamin C, vitamin B3), iron, and potassium. [23] Vitamin A, calcium, and sodium are present in moderate amounts. Compared to powdered pulp, only vitamin C is retained in the analysis of M. citrifolia juice. [24] The juice contains 34 mg of vitamin C per 100 g, which is 64% of the amount found in a raw navel orange (53 mg per 100 g of orange, or 89% of the Daily Value). [25] Sodium levels in M. citrifolia juice (about 3% of Dietary Reference Intake, DRI) [23] are high compared to an orange, while potassium content is moderate. [25]
Morinda citrifolia fruit contains several phytochemicals, including lignans, oligo- and polysaccharides, flavonoids, iridoids such as deacetylasperulosidic acid, [26] fatty acids, scopoletin, catechin, beta-sitosterol, damnacanthal, and alkaloids. [27]
Rubiaceae is a family of flowering plants, commonly known as the coffee, madder, or bedstraw family. It consists of terrestrial trees, shrubs, lianas, or herbs that are recognizable by simple, opposite leaves with interpetiolar stipules and sympetalous actinomorphic flowers. The family contains about 14,100 species in about 580 genera, which makes it the fourth-largest angiosperm family. Rubiaceae has a cosmopolitan distribution; however, the largest species diversity is concentrated in the tropics and subtropics. Economically important genera include Coffea, the source of coffee; Cinchona, the source of the antimalarial alkaloid quinine; ornamental cultivars ; and historically some dye plants.
Breadfruit is a species of flowering tree in the mulberry and jackfruit family (Moraceae) believed to be a domesticated descendant of Artocarpus camansi originating in New Guinea, the Maluku Islands, and the Philippines. It was initially spread to Oceania via the Austronesian expansion. It was further spread to other tropical regions of the world during the Colonial Era. British and French navigators introduced a few Polynesian seedless varieties to Caribbean islands during the late 18th century. Today it is grown in some 90 countries throughout South and Southeast Asia, the Pacific Ocean, the Caribbean, Central America and Africa. Its name is derived from the texture of the moderately ripe fruit when cooked, similar to freshly baked bread and having a potato-like flavor.
Rambutan is a medium-sized tropical tree in the family Sapindaceae. The name also refers to the edible fruit produced by this tree. The rambutan is native to Southeast Asia. It is closely related to several other edible tropical fruits, including the lychee, longan, pulasan, and quenepa.
Carambola, also known as star fruit, is the fruit of Averrhoa carambola, a species of tree native to tropical Southeast Asia. The edible fruit has distinctive ridges running down its sides. When cut in cross-section, it resembles a star, giving it the name of star fruit. The entire fruit is edible, usually raw, and may be cooked or made into relishes, preserves, garnish, and juices. It is commonly consumed in Southeast Asia, South Asia, the South Pacific, Micronesia, parts of East Asia, the United States, parts of Latin America, and the Caribbean. The tree is cultivated throughout tropical areas of the world.
Morus, a genus of flowering plants in the family Moraceae, consists of 19 species of deciduous trees commonly known as mulberries, growing wild and under cultivation in many temperate world regions. Generally, the genus has 64 subordinate taxa, three of which are well-known and are ostensibly named for the fruit color of the best-known cultivar: white, red, and black mulberry, with numerous cultivars and some taxa currently unchecked and awaiting taxonomic scrutiny. M. alba is native to South Asia, but is widely distributed across Europe, Southern Africa, South America, and North America. M. alba is also the species most preferred by the silkworm, and is regarded as an invasive species in Brazil and the United States.
Sambucus is a genus of flowering plants in the family Adoxaceae. The various species are commonly referred to as elder, elderflower or elderberry.

The jackfruit is a species of tree in the fig, mulberry, and breadfruit family (Moraceae). The jackfruit is the largest tree fruit, reaching as much as 55 kg in weight, 90 cm in length, and 50 cm in diameter. A mature jackfruit tree produces some 200 fruits per year, with older trees bearing up to 500 fruits in a year. The jackfruit is a multiple fruit composed of hundreds to thousands of individual flowers, and the fleshy petals of the unripe fruit are eaten.
Aleurites moluccanus, the candlenut, is a flowering tree in the spurge family, Euphorbiaceae, also known as candleberry, Indian walnut, kemiri, varnish tree, nuez de la India, buah keras, godou, kukui nut tree, and rata kekuna.
Noni juice is derived from the fruit of the Morinda citrifolia tree indigenous to Southeast Asia and Australasia. It has been promoted, illegally in several cases, as a cure for a number of human diseases. However, there is no evidence to support any claims of therapeutic benefit.
Averrhoa bilimbi is a fruit-bearing tree of the genus Averrhoa, family Oxalidaceae. It is believed to be originally native to the Maluku Islands of Indonesia but has naturalized and is common throughout Southeast Asia. It is cultivated in parts of tropical South Asia and the Americas. It bears edible but extremely sour fruits. It is a close relative of the carambola tree.
Morinda is a genus of flowering plants in the madder family, Rubiaceae. The generic name is derived from the Latin words morus "mulberry", from the appearance of the fruits, and indica, meaning "of India".
Multi-fruits, also called collective fruits, are fruiting bodies formed from a cluster of flowers, the inflorescence. Each flower in the inflorescence produces a fruit, but these mature into a single mass. After flowering, the mass is called an infructescence. Examples are the fig, pineapple, mulberry, osage orange, and jackfruit.
