Tamarind ( Tamarindus indica) is a Legume tree bearing edible fruit that is indigenous to tropical Africa and naturalized in Asia. The genus Tamarindus is monotypic taxon, meaning that it contains only this species. It belongs to the family Fabaceae.
The tamarind tree produces brown, pod-like that contain a sweet, tangy pulp, which is used in cuisines around the world. The pulp is also used in traditional medicine and as a dye. The wood can be used for woodworking, and tamarind seed oil can be extracted from the seeds. Its young leaves are used in Indian cuisine and Filipino cuisine. Because tamarind has multiple uses, it is cultivated worldwide in Tropical zone and Subtropics.
The evergreen leaves are alternately arranged and paripinnately compound. The leaflets are bright green, elliptic-ovular, Pinnation veined, and less than in length. The branches droop from a single, central trunk as the tree matures, and are often pruned in agriculture to optimize tree density and ease of fruit harvest.
As a tropical species, it is frost-sensitive. The pinnate leaves with opposite leaflets give a billowing effect in the wind. Tamarind timber consists of hard, dark red heartwood and softer, yellowish sapwood.
The tamarind flowers bloom (although inconspicuously), with red and yellow elongated flowers. Flowers are 2.5 cm (1 in) wide, five-petalled, borne in small , and yellow with orange or red streaks. are pink as the four are pink and are lost when the flower Blossom.
The fruit has a fleshy, acidic pulp, becoming mature when the flesh is colored brown or reddish brown. The tamarinds of Asia have longer pods (containing six to 12 seeds), whereas African and West Indian varieties have shorter pods (containing one to six seeds). The seeds are somewhat flattened, and a glossy brown. The fruit is sweet and sour in taste. A mature tree may produce up to of fruit each year.
In Colombia, Nicaragua, Costa Rica, Ecuador, Cuba, the Dominican Republic, Guatemala, El Salvador, Honduras, Mexico, Peru, Puerto Rico, Venezuela, Italy, Spain, and throughout the Lusophone, it is called tamarindo. In those countries it is often used to make the beverage of the same name (or agua de tamarindo). In the Caribbean, tamarind is sometimes called tamón.
Countries in Southeast Asia like Indonesia call it asam jawa (Java island sour fruit) or simply asam, and sukaer in Timor. While in the Philippines, it is called sampalok or sampaloc in Filipino, and sambag in Cebuano language. Tamarind ( Tamarindus indica) is sometimes confused with "Manila tamarind" ( Pithecellobium dulce). While in the same taxonomic family Fabaceae, Manila tamarind is a different plant native to Mexico and known locally as Pithecellobium.
In the 16th century, it was introduced to Mexico and Central America, and to a lesser degree to South America, by Spanish and Portuguese colonists, to the degree that it became a staple ingredient in the region's cuisine.
Tamarind pulp is the most common part of the tamarind plant used in , curries, and sauces, such as Worcestershire sauce, HP Sauce, some brands of barbecue sauce, and the traditional sharbat syrup drink.

Across the Middle East, from the Levant to Iran, tamarind is used in savory dishes, notably meat-based stews, and often combined with dried fruits to achieve a sweet-sour tang. "Tamarind is the 'sour secret of Syrian cooking'". PRI. July 2014 During Ramadan, tamarind is used to prepare a traditional beverage known as "Tamr hindi," which is particularly popular in the Levant region.

Tamarind has been integrated into kosher and Jewish cuisine across several diasporas, beginning with its introduction to the Middle East via Jewish merchants on the Silk Road in the 7th century. Syrian Jews prepare tamarind syrup, known as ou or ouc, by soaking, straining, and boiling the fruit pulp with sugar and lemon, using it in dishes such as yebra (stuffed grape leaves), bazargan (bulgur salad), keftes (sweet-sour meatballs), and laham b'ajeen (meat flatbread). In India, Baghdadi, Cochin, and Bene Israel Jews use tamarind in regional recipes like bamia khutta, mahmoora, tamarind rice, and lamb with red chilies. Syrian Jewish communities in Mexico have adapted tamarind-based dishes with local ingredients, exemplified by chicken with tamarind, apricots, and chipotle. In contemporary Israel, tamarind juice has gained popularity beyond traditional communities, aided by commercial offerings like Prigat's seasonal releases during Ramadan.
In the Philippines, the whole fruit is used as one of the souring agents of the sour soup sinigang (which can also use other sour fruits), as well as another type of soup called sinampalukan (which uses tamarind leaves).
In Sri Lanka, tamarind pulp has been used as a lime alternative, and in Senegal, the pulp is mixed with sugar to produce sweet meats known as 'bengal'. In India, tamarind pulp is made into a juice used in the preservation of fish, and in many countries of East Africa, the pulp is used in the making of a dish called ugali (a type of maize flour porridge).
Tamarind seeds need to be soaked and boiled in water before they are edible. The seeds are commonly used in jellies, marmalades and jams because they contain pectin which gives them jelly-forming properties, and have been used as a stabilizer to make cheese, ice cream and mayonnaise. In Indonesia, after the seeds have been roasted, they are consumed as a snack accompanied with salt and grated coconut and in Thailand tamarind seeds are used as a coffee alternative.
The leaves and bark are also edible, and the seeds can be cooked to make safe for consumption. Blanched, tender tamarind leaves are used in a Burmese salads called magyi ywet thoke (), a salad from Upper Myanmar that features tender blanched tamarind leaves, garlic, onions, roasted peanuts, and pounded dried shrimp. Tamarind seeds contain high levels of protein (26.9 grams per 100 grams) and oil (10.9 grams per 100 grams) and in some countries, tamarind seeds are used as an emergency food because of their high protein levels. The leaves of the tamarind plant are high in calcium and protein and have been consumed by domestic animals and wild animals, including elephants, as a fodder.
Tamarind kernel powder is used as sizing material for textile and jute processing, and in the manufacture of industrial gums and adhesives.
Tamarind seeds are used in the production of tamarind kernel powder which is used as a sizing agent in the textile industry because of its ability to absorb water and swell up, in India, tamarind kernel powder has also been used as a sizing agent in the production of cotton. In Bengal, tamarind seeds are used in the production of an oil used in varnishes. leaves and flowers are used as a setting agent for dyes.
Different parts of the tamarind plant have been used globally for other purposes in folk medicine. In the northern parts of Nigeria, the roots of the tamarind plant are thought to be useful for treating leprosy, and in America, tamarind pulp is considered in folk medicine to be a laxative and used for alleviating sunstroke and sore throats. In Thailand, the pulp has been transformed into a tablet in the belief it can reduce excess weight, and in Brazil, the pulp is used for its supposed hydrating effects. Tamarind seeds have been used in powdered form to possibly aid dysentery in India and Cambodia, and in Ethiopia, softened tamarind seeds are used as a possible treatment for parasitic worms.
Tamarind is a traditional food plant in Africa. Although not grown on a large-scale commercial basis, it has the potential to improve nutrition, boost food security, foster rural development, and support sustainable land care.
The tree is widely cultivated across India, especially in Maharashtra, Chhattisgarh, Karnataka, Telangana, Andhra Pradesh, and Tamil Nadu. Extensive tamarind orchards in India produced annually in the late 20th century. It has long been naturalized in Indonesia, Malaysia, Sri Lanka, the Philippines, the Caribbean, and Pacific Islands. Thailand has the largest plantations of the ASEAN nations, followed by Indonesia, Myanmar, and the Philippines. In parts of Southeast Asia, tamarind is called asam.
In the United States, it is a large-scale crop introduced for commercial use (second in net production quantity only to India), mainly in southern states, notably south Florida, and as a shade tree, along roadsides, in dooryards and in parks.

Distribution
Tamarindus indica is indigenous to tropical Africa, but has been cultivated for so long on the Indian subcontinent that it is sometimes reported to be indigenous there. It grows wild in Africa. In Arabia, it is found growing wild in Oman, especially Dhofar, where it grows on the sea-facing slopes of mountains. It reached South Asia likely through human transportation and cultivation several thousand years ago. It is widely distributed throughout the tropics, from Africa to South Asia. In Madagascar, its fruit and leaves are a well-known favorite of the ring-tailed lemur, providing as much as 50 percent of their food resources during the year if available.

Tamarind heartwood is reddish brown, sometimes with a purplish hue. The heartwood in tamarind tends to be narrow and is usually only present in older and larger trees. The pale yellow sapwood is sharply demarcated from the heartwood. Heartwood is said to be durable to very durable in decay resistance, and is also resistant to insects. Its sapwood is not durable and is prone to attack by insects and fungi as well as spalting. Due to its density and interlocked grain, tamarind is considered difficult to work. Heartwood has a pronounced blunting effect on cutting edges. Tamarind turns, glues, and finishes well. The heartwood is able to take a high natural polish.
