Vernacular names
The name "okra", most often used in the United States and the Philippines, is of West African origin and is cognate with "ọ́kụ̀rụ̀" in Igbo, a language spoken in Nigeria.[2] Okra is often known as "Lady's Fingers" outside of the United States.[3] In various Bantu languages, okra is called "kingombo" or a variant thereof, and this is the origin of its name in Portuguese ("quiabo"), Spanish, Dutch and French, and also of the name "gumbo", used in parts of the United States and English-speaking Caribbean for either the vegetable, or a stew based on it[4]. In the United Kingdom it is often called as "bhindi", from its Hindi name "bhindi" or "bhendi". In South and South East Europe it is known as bamya (bamija).It is called "Molondrón" in the Dominican Republic, a Caribbean Spanish-speaking country.
Structure and physiology
The species is an annual or perennial, growing to 2 m tall. It is related to such species as cotton, cocoa, and hibiscus. The leaves are 10–20 cm long and broad, palmately lobed with 5–7 lobes. The flowers are 4–8 cm diameter, with five white to yellow petals, often with a red or purple spot at the base of each petal. The fruit is a capsule up to 18 cm long, containing numerous seeds.Abelmoschus esculentus is cultivated throughout the tropical and warm temperate regions of the world for its fibrous fruits or pods containing round, white seeds. It is among the most heat- and drought-tolerant vegetable species in the world—but severe frost can damage the pods[citation needed]—and will tolerate poor soils with heavy clay and intermittent moisture.
In cultivation, the seeds are soaked overnight prior to planting to a depth of 1–2 cm. Germination occurs between six days (soaked seeds) and three weeks. Seedlings require ample water.[citation needed] The seed pods rapidly become fibrous and woody and must be harvested within a week of the fruit being pollinated to be edible.[4] The fruits are harvested when immature and eaten as a vegetable.
Origin and distribution
Okra is an allopolyploid of uncertain parentage (proposed parents include Abelmoschus ficulneus, Abelmoschus tuberculatus and a reported "diploid" form of okra). Truly wild, as opposed to naturalised, populations, are not definitely known, and the species may be a cultigen.The geographical origin of okra is disputed, with supporters of South Asian, Ethiopian and West African origins. Supporters of a South Asian origin point to the presence of its proposed parents in that region. Opposed to this is the lack of a word[citation needed] for okra in the ancient languages of India, suggesting that it arrived there in the Common Era. Supporters of a West African origin point to the greater diversity of okra in that region; however confusion between Okra and Abelmoschus caillei (West African okra) casts doubt on those analyses.
The Egyptians and Moors of the 12th and 13th centuries used the Arabic word for the plant, suggesting that it had come from the east. The plant may have entered south west Asia across the Red Sea or the Bab-el-Mandeb strait to the Arabian Peninsula, rather than north across the Sahara, or from India. One of the earliest accounts is by a Spanish Moor who visited Egypt in 1216, who described the plant under cultivation by the locals who ate the tender, young pods with meal.[4].
From Arabia, the plant spread around the shores of the Mediterranean Sea and eastward. The plant was introduced to the Americas by ships plying the Atlantic slave trade[5] by 1658, when its presence was recorded in Brazil. It was further documented in Suriname in 1686.
Okra may have been introduced to southeastern North America in the early 18th century. It was being grown as far north as Philadelphia by 1748. Thomas Jefferson noted that it was well established in Virginia by 1781. It was commonplace throughout the Southern United States by 1800 and the first mention of different cultivars was in 1806.[4]

In Syria, Tunisia, Egypt, Greece, Iran, Iraq, Jordan, Lebanon, Turkey, and Yemen,[6] and other parts of the eastern Mediterranean, including Cyprus and Israel, okra is widely used in a thick stew made with vegetables and meat. It is one of the most popular vegetables among West Asians, North Indians and Pakistanis alike. In most of West Asia, okra is known as bamia or bamya. West Asian cuisine usually uses young okra pods and they are usually cooked whole. In India, the harvesting is done at a later stage, when the pods and seeds are larger.
It is popular in India and Pakistan, where chopped pieces are stir fried with spices, pickled, salted or added to gravy-based preparations like Bhindi Ghosht or sambar. In western parts of India (Gujarat, Maharashtra), okra is often stir-fried with some sugar. Okra is also used in Kadhi. The ladies finger is used to make sambar (kodel ) in Udupi cuisine.
In Singapore, okra is commonly a part of yong tau foo cuisine. As a part of the cuisine, it is stuffed with processed fish paste (Surimi) and boiled with a selection of vegetables and tofu. It is then served in a soup with noodles.
Okra forms part of several regional "signature" dishes. Frango com quiabo (chicken with okra) is a Brazilian dish that is especially famous in the region of Minas Gerais. Gumbo, a hearty stew whose key ingredient is okra, is found throughout the Gulf Coast of the United States and in the South Carolina Lowcountry. Breaded, deep fried okra is eaten in the southern United States. Okra is also an ingredient expected in callaloo, a Caribbean dish and the national dish of Trinidad and Tobago. It is also a part of the national dish of Barbados coucou (turned cornmeal). Okra is also eaten in Nigeria, where draw soup is a popular dish, often eaten with garri or cassava. In Vietnam, okra is the important ingredient in the dish canh chua. Okra slices can also be added to ratatouille, combining very well with the other ingredients of this French popular dish.[7]
Okra leaves may be cooked in a similar way to the greens of beets or dandelions.[8] The leaves are also eaten raw in salads.[citation needed] Okra seeds may be roasted and ground to form a caffeinate-free substitute for coffee.[4] When importation of coffee was disrupted by the American Civil War in 1861, the Austin State Gazette noted, "An acre of okra will produce seed enough to furnish a plantation of fifty negroes with coffee in every way equal to that imported from Rio."[9]
Okra oil is a pressed seed oil, extracted from the seeds of the okra. The greenish-yellow edible oil has a pleasant taste and odor, and is high in unsaturated fats such as oleic acid and linoleic acid.[10] The oil content of the seed can be quite high at about 40%. Oil yields from okra crops are also high. At 794 kg/ha, the yield was exceeded only by that of sunflower oil in one trial.[11] Common Okra seed is reported to contain only 15% oil [12]
