The calabash, bottle gourd,^[1] or white-flowered gourd,^[2] Lagenaria siceraria (synonym Lagenaria vulgaris Ser.), also known by many other names that include: opo squash (from Tagalog: upo), long melon, suzza melon, New Guinea bean and Tasmania bean^[3] is a vine grown for its fruit, which can either be harvested young and used as a vegetable, or harvested mature, dried, and used as a bottle, utensil, or pipe. The fresh fruit has a light-green smooth skin and a white flesh. Rounder varieties are called calabash gourds. They grow in a variety of shapes: they can be huge and rounded, small and bottle shaped, or slim and serpentine, more than a metre long. Because bottle gourds are also called "calabashes", they are sometimes confused with the hard, hollow fruits of the unrelated calabash tree, Crescentia cujete, whose fruits are also used to make utensils, containers, and musical instruments.^[4] The gourd was one of the first cultivated plants in the world, grown not primarily for food, but for use as water containers. The bottle gourd may have been carried from Africa to Asia, Europe, and the Americas in the course of human migration,^[5] or by seeds floating across the oceans inside the gourd. It has been proven to be in the New World prior to the arrival of Christopher Columbus.^[6]

Origin and dispersal

The bottle gourd is a commonly cultivated plant in tropical and subtropical areas of the world, now believed by some to have spread or originated from wild populations in southern Africa. Stands of L. siceraria, which may be source plants, and not merely domesticated stands, were reported in Zimbabwe in 2004.^[7] This apparent domestication source plant produces thinner-walled fruit that, when dried, would not endure the rigors of use on long journeys as a water container. Today's gourd may owe its tough, waterproof wall to selection pressures over its long history of domestication.^[8]

Cultivation

Gourds were cultivated in Africa, Asia, Europe, and the Americas for thousands of years before Columbus' discovery of America. Historically, in Europe,^[9] Walahfrid Strabo (808–849), abbot and poet from Reichenau and advisor to the Carolingian kings, discussed it in his Hortulus as one of the 23 plants of an ideal garden.^[10][11]

Recent research indicates some gourds have an African origin and that there were at least two unrelated domestications: one that occurred 8,000-9,000 years ago, based on the analysis of archeological samples found in Asia, and a second domestication, which occurred 4,000 years ago, traced from archeological discoveries in Egypt.

The mystery of the bottle gourd – namely that this African or Eurasian species was being grown in America over 8,000 years ago^[12] – came about from the difficulty in understanding how it came to be in the Americas. The bottle gourd was originally thought to have drifted across the Atlantic Ocean from Africa to North and South America, but genetic research on archeological samples published by the National Academy of Sciences in December 2005 suggested that it may have been domesticated earlier than food crops and livestock and, like dogs, was brought into the New World at the end of the ice age to the native Paleo-Indians. This study showed that gourds found in American archaeological finds appeared closer to Asian variants than to African ones.^[13]

In February 2014, the original hypothesis was revived based on a more thorough genetic study. Researchers examined the entire genome, including the plasmid genome, and concluded that American specimens were most closely related to wild African variants and could have drifted over the ocean several or many times as long as 10,000 years ago.^[14]

Nowadays, bottle gourds are grown by direct sowing of seeds or transplanting 15- to 20-day-old seedlings. It prefers well-drained, moist, rich soil. It requires plenty of moisture in the growing season and a warm sunny position sheltered from the wind. It is cultivated in small places such as in a pot, spread on a trellis or roof. In rural areas, many houses with thatched roofs are found covered with the gourd vines. Bottle gourds grow very rapidly and their stems can reach a length of 9 m in the summer, so they need a solid support to climb by the pole or trellis along the stem. If planted under a tall tree, the vine can grow up to the top of the tree. To get more fruit, sometimes farmers cut off the tip of the vine when it has grown to 6–8 feet long. This forces the plant to produce side branches that produce fruit much sooner and more flowers and more fruit. The plant produces white flowers. The male flowers have long peduncles and the females have short ones with an ovary of the shape of the fruit. Sometimes, the female flowers drop off without growing into a gourd due to the failure of pollination if no bee activity occurs in the garden area. To solve the problem, hand pollination can be used.

Crops are ready for harvest within two months; yield ranges from 35–40 m tons/ha.

Occasional toxicity

Like other members of the Cucurbitaceae family, gourds contain cucurbitacins that are known to be cytotoxic at a high concentration. The tetracyclic triterpenoid cucurbitacins present in fruits and vegetables of the cucumber family are responsible for the bitter taste, and could cause ulcers in the stomach. In extreme cases, people have died from drinking the juice of gourds.^[15][16][17] The toxic cases are usually due to the gourd being used to make juice, which the drinkers attested to being unusually bitter.^[18] And in the three lethal cases, the victims were all diabetics in their 50s and 60s.^[18]

However, the plant is not normally toxic when eaten and is safe to consume. The excessively bitter (and toxic) gourds are due to improper storage (temperature swings or high temperature) and over-ripening.^[19]

To avoid poisoning, it is advised to:^[18]

1. Taste a small piece of the gourd to make sure it is not unusually bitter, before making juice
2. Discard all excessively bitter gourd or juice
3. Do not mix the juice of gourds with other juices, such as that of bitter gourd, so as not to mask the taste if it has gone bad

Culinary uses

Central America

In Central America, the seeds of the bottle gourd are toasted and ground with other ingredients (including rice, cinnamon, and allspice) to make the drink horchata. (The calabash tree, Crescentia cujete, is known locally as morro or jícaro; that is another "calabash"). In Colombia and Venezuela, the calabash tree is known as a taparo or totumo (it is another "calabash" plant).

East Asia

China

It is frequently used in southern Chinese cuisine in either a stir-fry or a soup. The Mandarin name for calabash is hulu (simplified Chinese: 葫芦; traditional Chinese: 葫蘆; pinyin: húlu) or huzi (Chinese: 葫子; pinyin: húzi). Two common kinds of calabash are sold in Chinese stores: the opo kind, which is elongated but still plump, and mao gua which translates to "hairy squash". It is very similar to opo, but it has hairs, as its Chinese name references. The hairs, although small, can become embedded in the skin, but it is usually safe for adults to handle.

Japan

In Japan, the species is known as hyōtan (瓢箪, 瓢簞) or yūgao (夕顔), with the former word referring particularly to the larger-fruiting variety whose fruits are used mostly for making containers or other handicrafts, and the latter referring to the smaller-fruiting variety whose fruits are more edible. Names used to refer particularly to the fruit of one or another variety of this species include fukube (瓠, 瓢, ふくべ) and hisago (瓠, 匏, 瓢, ひさご). It is most commonly sold in the form of dried, marinated strips known as kanpyō and is commonly used as an ingredient for making makizushi (rolled sushi).

Korea

In Korea, both the plant and its fruit are known as bak (박). Traditionally, the inside has been eaten as pot-herbs and the outside cut in half to make bowls.

In Korean cuisine, fresh or dried flesh of bak is used as namul vegetable. Dried flesh of bak, called bakgoji, makes a good addition to japchae^[20] and gimbap.^[21]

Ingredients

• bakgoji – dried calabash, prepared by scraping out the flesh of a calabash and sun-drying it
• baksok – calabash flesh, prepared by scraping out the flesh of a calabash, adding salt to draw moisture out and squeezing them, then removing the seeds

Dishes

• baknamul – a type of namul, made by slicing an unripe calabash thinly and stir-frying the slices with soy sauce and ground beef or peeled shrimp, then seasoning it with chopped spring onions, toasted sesame seeds, and ground black pepper
• bakgojinamul – a type of namul, made by stir-frying soaked bakgoji (dried calabash) in oil, and later adding deulkkaemul (perilla water), soup soy sauce, chopped spring onions, chopped garlic, and toasted sesame seeds, then boiling until liquid is reduced
• baksoknamul – a type of namul, made by slicing the baksok (calabash flesh) of a young calabash thinly, stir-frying the slices in oil with songi mushrooms, chopped spring onions, and toasted sesame seeds, then adding water and boiling until liquid is reduced, before finally adding sesame oil
• baksoksaengchae – a type of namul, made by seasoning well-salted and squeezed raw baksok (calabash flesh) with gochujang, toasted sesame seeds, and chopped garlic

Europe

In Italian cuisine, it is known as cucuzza (plural cucuzze).

Middle East

In Arabic, it is called qara. In Aramaic, it is called kura. In the Talmudic period, the young fruits were boiled, whilst the mature fruits were eaten as dessert. The tender young gourd is cooked as a summer squash. It is believed that this plant was consumed by Prophet Jonah when he was spitted out by the Whale.

South Asia

Bangladesh

In Bangladesh, it is called laau (লাউ) or kaddu (কদু).

India

In India, it is known as lauki (लौकी / લૌકી), laau (लाऊ,), dudhi (दूदी / દૂદી) or ghiya (घीया / ઘીયા) in Hindi/Urdu/Gujarati/Bengali/Marathi; Laau (লাউ) (ଲାଉ) in Odia; aal (आल) in Marwari; churakka (ചുരക്ക) in Malayalam; jatilao in Assamese; sorakaaya (సొర కాయ) or anapakaya in Telugu; dudhi-Bhopala (दुधी भोपळा) in Marathi; sorekayi (ಸೋರೆಕಾಯಿ) in Kannada; sajmain in Maithili and Labu (ලබු) in Sinhalese and suraikkaai (சுரைக்காய் colloquilly sorakkay) in Tamil. A popular north indian dish is lauki channa, (channa dal and diced gourd in a semidry gravy). In the state of Maharashtra in India, a preparation similar to lauki channa is popular. However, the skin is removed prior to making the dish. The skin is used in making a dry spicy chutney preparation. In Kashmiri, it is called an al, or more often a Kaesher al or Zeeth (long) al.

Nepal

In Nepal, it is called lauka (लौका).

Pakistan

In Pakistan, the calabash is known as kaddu or lauki in Urdu, and kaddu in Punjabi and Pashto.

Sri Lanka

In Sri Lanka, it is used in combination with rice to make a variety of milk rice (labu Kiribath, ලබු කිරිබත්), which is one of the popular native dishes among Sri Lankans.

Southeast Asia

Burma

In Burma, it is known as ဗူးသီး boo thee, a popular fruit; young leaves are also boiled and eaten with spicy hot, fermented fish sauce called nga peet. It can also be cut up, coated in batter and deep fried to make fritters, which are eaten with Burmese mohinga.

Philippines

In the Philippines, it is known as upo (ᜂᜉᜓ).

Vietnam

In Vietnam, bầu (opo squash), bầu canh, or bầu nậm is a very popular vegetable, commonly cooked in soup with shrimp, meatballs, clams, various fish like freshwater catfish or snakehead fish, or crab. Opo squash is also commonly stir-fried with meat or seafood, or incorporated in hotpot. It is also as a medicine.

The shoots, tendrils, and leaves of the plant may also be eaten as greens.

Cultural uses

Africa

Hollowed-out and dried calabashes are a very typical utensil in households across West Africa. They are used to clean rice, carry water, and as food containers. Smaller sizes are used as bowls to drink palm wine.

Calabashes are used in making the West African kora (a harp-lute), xalam/ngoni (a lute) and the goje (a traditional fiddle). They also serve as resonators underneath the balafon (West African marimba). The calabash is also used in making the shegureh (a Sierra Leonean women's rattle)^[22] and balangi (a Sierra Leonean type of balafon) musical instruments. Sometimes, large calabashes are simply hollowed, dried, and used as percussion instruments, especially by Fulani, Songhai, Gur-speaking and Hausa peoples. In Nigeria, the calabash has been used to avoid a law requiring the wearing of a helmet on a motorcycle.^[23] In South Africa, it is commonly used as a drinking vessel by tribes such as the Zulus. Erbore tribe children in Ethiopia wear hats made from the calabash to protect them from the sun. Recently, the Soccer City stadium which hosted the FIFA World Cup has been completed and its shape takes inspiration from the calabash.

Caribbean

Calabash is primarily used for utensils, such as cups, bowls, and basins in rural areas. It can be used for carrying water or can be made for carrying items, such as fish, when fishing. In some Caribbean countries, it is worked, painted, and decorated as shoulder bags or other items by artisans, and sold to tourists.

In Jamaica, it is also a reference to the natural lifestyle of Rastafarians. As a cup, bowl, or even water-pipe or "bong", the calabash is considered consistent with the "Ital" or vital lifestyle of not using refined products such as table salt, or using modern cooking methods, such as microwaves. In Haiti, the plant is called kalbas kouran, literally, "running calabash", and is used to make the sacred rattle emblematic of the Vodou priesthood, called an asson. As such, the plant is highly respected. It is also the national tree of St. Lucia.

China

The hulu is an ancient symbol for health. In the old days, doctors would carry medicine inside it, so it has fabled properties for healing. The hulu is believed to absorb negative earth-based ki (energy) that would otherwise affect health, and is a traditional Chinese medicine cure. Dried calabash is also used as containers of liquids, often liquors or medicines. Calabash gourds were also grown in earthen molds to form different shapes with imprinted floral or arabesque design and dried to house pet crickets, which were kept for their song and fighting abilities. The texture of the gourd lends itself nicely to the sound of the insect, much like a musical instrument. The musical instrument, hulusi, is a kind of flute. The bottle gourd is a symbol of the Xian immortals.

Costa Rica

Note that "guacal" in Costa Rica refers to C. cujete tree calabash.

The Costa Rican town of Santa Bárbara de Santa Cruz holds a traditional annual dance of the calabashes (baile de los guacales). Since 2000, the activity has been considered of cultural interest to the community, and all participants receive a hand-painted calabash vessel to thank them for their economic contribution (which they paid in the form of an entrance ticket).^[24]

Aboriginals throughout the country traditionally serve chicha in calabash vessels to the participants of special events such as the baile de los diablitos (dance of the little fiends).^[25]

Hawaii

In Hawaii, a calabash is a large serving bowl, usually made from a hardwood rather than from the calabash gourd as in Maroon cultures. It is used on a buffet table or in the middle of the dining table. The use of the calabash in Hawaii has led to terms like "calabash family" or "calabash cousins", indicating an extended family grown up around shared meals and close friendships.

This gourd is often dried when ripe and used as a percussion instrument called an ipu heke in contemporary and ancient hula.

India

Calabash is used in many string instruments in India as a resonator. Instruments that look like guitars are made of wood, but they can have a calabash resonator at the end of the strings table called toomba. The sitar, the surbahar, the tanpura (south of India, tambura north of India), may have a toomba. In some cases, the toomba may not be functional, but, if the instrument is large, it keeps its place because of its balance function; that is the case of the Saraswati veena. Other instruments like rudra veena and vichitra veena have two large calabash resonators at both ends of the strings table. The Baul singers of Bengal have their musical instruments made out of calabash. The practice is also common among Buddhist and Jain sages.^[26]

These toombas are made of dried calabash gourds, using special cultivars that were originally imported from Africa and Madagascar. They are mostly grown in Bengal and near Miraj, Maharashtra. These gourds are valuable items and they are carefully tended; for example, sometimes they are given injections to stop worms and insects from making holes while they are drying, etc.

Hindu ascetics (sadhu) traditionally use a dried gourd vessel called the kamandalu. The juice of bottle gourd is considered to have medicinal properties and to be very good for health.

In parts of India, the dried, unpunctured gourd is used as a float (called surai-kuduvai in Tamil) to learn swimming in rural areas.

Mexico

Note that "jícara" refers to the Crescentia cujete calabash

In many rural parts of Mexico, the calabash is dried and carved hollow to create a bule or a guaje, a gourd used to carry water around like a canteen. The gourd cut in half, called jícara, gave the parallel name to a clay cup jícara.

South America

In Brazil, Chile, Argentina, Uruguay, and Paraguay, calabash gourds are dried and carved into mates (Quichua word, adopted in Spanish language), the traditional container for mate, the popular caffeinated, tea-like drink brewed from the yerba mate plant (the container is called cuia, porongo, or cabaça in Brazil). In the same region, it is called mate as is also the calabash from which the drinking vessels are made, and, in Peru, (where the practice of drinking mate is not adopted,) it is used in a popular practice for the making of mate burilado; "burilado" is the technique adopted for decorating the mate calabashes. In Brazil, gourds also commonly used as the resonator for the berimbau, the signature instrument of capoeira, a martial art/dance developed in Brazilian plantations by African slaves. The calabash gourd is possibly mankind's oldest instrument resonator.

In the region where Incas lived (Peru, Bolivia, Ecuador), calabash gourds are known to have been used for medicinal purposes for over a thousand years by Andean cultures. The Inca culture applied folklore symbology to gourds to pass down from one generation to another, and this practice is still familiar and valued.

Bowls made of calabash were used by indigenous Brazilians as utensils made to serve food, and the practice is still retained in some remote areas of Brazil (originally by populations of various ethnicities, origins and regions, but nowadays mainly the indigenes themselves).

Venezuela

Note that "totuma" refers to the vessel made of C. cujete calabash.

Former president Hugo Chávez of Venezuela suggested Venezuelans avoid showers longer than three minutes.^[31][32] Critics of Chavez ridiculed this by reductio ad absurdum, ironically suggesting the use of a totuma to bathe (although Chavez himself did not suggest this),^[33][34] inferring that people have to bathe with "a totuma of water", the quantity of water that only one totuma can hold. It is a joke because it exaggerates the original words, because a totuma is a device that carries very little quantity of water, not enough for bathing (not even to get wet).

Other uses

Additionally, the gourd can be dried and used to smoke pipe tobacco, usually constructed with a meerschaum lining holding the lit tobacco within the gourd. A typical design yielded by this squash is recognized (theatrically) as the pipe of Sherlock Holmes, but Doyle never mentioned Holmes using a calabash pipe. It was the preferred pipe for stage actors portraying Holmes, because they could balance this pipe better than other styles while delivering their lines. See, Smoking pipe (tobacco)#Calabash.
