Durian

 The Durian is the fruit of several tree spices belonging to the genus Durio and the Malvaceaefamily(although some taxonomists place Durio in a distinct family, Durionaceae). Widely known and revered in southeast Asia as the "king of fruits", the durian is distinctive for its large size, unique odor, and formidable thorn-covered husk. The fruit can grow as large as 30 centimetres (12 in) long and 15 centimetres (6 in) in diameter, and it typically weighs one to three kilograms (2 to 7 lb). Its shape ranges from oblong to round, the colour of its husk green to brown, and its flesh pale yellow to red, depending on the species.

The edible flesh emits a distinctive odor, strong and penetrating even when the husk is intact. Some people regard the durian as fragrant; others find the aroma overpowering and offensive. The smell evokes reactions from deep appreciation to intense disgust, and has been described variously as almonds, rotten onions, turpentine and gym socks. The odour has led to the fruit's banishment from certain hotels and public transportation in southeast Asia.

The durian, native to Brunei, Indonesia and Malaysia, has been known to the Western world for about 600 years. The 19th-century British naturalist Alfred Russel Wallace famously described its flesh as "a rich custard highly flavoured with almonds". The flesh can be consumed at various stages of ripeness, and it is used to flavour a wide variety of savoury and sweet edibles in Southeast Asian cuisines. The seeds can also be eaten when cooked.

There are 30 recognised Durio species, at least nine of which produce edible fruit. Durio zibethinus is the only species available in the international market: other species are sold in their local regions. There are hundreds of durian cultivars; many consumers express preferences for specific cultivars, which fetch higher prices in the market.

Durian fruit contains a high amount of sugar, vitamin C, potassium, and the serotonergic amino acid tryptophan,and is a good source ofcarbohydrates, proteins, and fats. It is recommended as a good source of raw fats by several raw food advocates, while others classify it as a high-glycemic food, recommending to minimize its consumption.

In Malaysia, a decoction of the leaves and roots used to be prescribed as an antipyretic. The leaf juice is applied on the head of a fever patient. The most complete description of the medicinal use of the durian as remedies for fevers is a Malay prescription, collected by Burkill and Haniff in 1930. It instructs the reader to boil the roots of Hibiscus rosa-sinensis with the roots of Durio zibethinusNephelium longanNephelium mutabile and Artocarpus integrifolia, and drink the decoction or use it as a poultice.

In the 1920s, Durian Fruit Products, Inc., of New York City launched a product called "Dur-India" as a health food supplement, selling atUS$9 for a dozen bottles, each containing 63 tablets. The tablets allegedly contained durian and a species of the genus Allium from India and vitamin E. The company promoted the supplement saying that it provides "more concentrated healthful energy in food form than any other product the world affords".
