Synonyms[1]

Allium sativum, commonly known as garlic, is a species in the onion genus, Allium.

Its close relatives include the onion, shallot, leek, chive,[2] and rakkyo.[3] With a history of over 7,000 years of human consumption and use, garlic is native to central Asia,[4] and has long been a staple in the Mediterranean region, as well as a frequent seasoning in Asia, Africa, and Europe. It was known to Ancient Egyptians, and has been used both as a food flavoring and as a traditional medicine.[5][6]

Description[edit]

Allium sativum is a bulbous plant. It grows up to 1.2 m (4 ft) in height. Its hardiness is USDA Zone 8. It produces hermaphrodite flowers. It is pollinated by bees and other insects.[7]

Origin and major types[edit]

Allium sativum grows in the wild in areas where it has become naturalized. The "wild garlic", "crow garlic", and "field garlic" of Britain are members of the species Allium ursinum, Allium vineale, and Allium oleraceum, respectively. Identification of the wild progenitor of common garlic is difficult, due to the sterility of its many cultivars which may all be descended from the species Allium longicuspis, which grows wild in central and southwestern Asia.[8][9][10]

In North America, Allium vineale (known as "wild garlic" or "crow garlic") and Allium canadense, known as "meadow garlic" or "wild garlic" and "wild onion", are common weeds in fields.[11] So-called elephant garlic is actually a wild leek (Allium ampeloprasum), and not a true garlic. Single clove garlic (also called pearl or solo garlic) originated in the Yunnan province of China.

Subspecies and varieties[edit]

There are two subspecies of A. sativum,[14] ten major groups of varieties, and hundreds of varieties or cultivars.

  • A. sativum var. ophioscorodon (Link) Döll, called Ophioscorodon, or hard-necked garlic, includes porcelain garlics, rocambole garlic, and purple stripe garlics. It is sometimes considered to be a separate species, Allium ophioscorodon G.Don.
  • A. sativum var. sativum, or soft-necked garlic, includes artichoke garlic, silverskin garlic, and creole garlic.

Cultivation[edit]

Garlic is easy to grow and can be grown year-round in mild climates. While sexual propagation of garlic is possible, nearly all of the garlic in cultivation is propagated asexually, by planting individual cloves in the ground.[9] In colder climates, cloves are planted in the autumn, about six weeks before the soil freezes, and harvested in late spring or early summer. The cloves must be planted deep enough to prevent freeze/thaw, which causes mold or white rot.[15] Garlic plants are usually very hardy, and are not attacked by many pests or diseases. Garlic plants are said to repel rabbits and moles.[3] However, two of the major pathogens that attack garlic are nematodes and white rot disease, which remain in the soil indefinitely after the ground has become infected.[9] Garlic can also suffer from pink root, a typically nonfatal disease that stunts the roots and turns them pink or red.[16]

Garlic plants can be grown closely together, leaving enough space for the bulbs to mature, and are easily grown in containers of sufficient depth. Garlic does well in loose, dry, well-drained soils in sunny locations, and is hardy throughout USDA climate zones 4–9. When selecting garlic for planting, it is important to pick large bulbs from which to separate cloves. Large cloves, along with proper spacing in the planting bed, will also improve bulb size. Garlic plants prefer to grow in a soil with a high organic material content, but are capable of growing in a wide range of soil conditions and pH levels.[9]

There are different varieties or subspecies of garlic, most notably hardneck garlic and softneck garlic. The latitude where the garlic is grown affects the choice of type, as garlic can be day-length sensitive. Hardneck garlic is generally grown in cooler climates; softneck garlic is generally grown closer to the equator.[17][18]

Garlic scapes are removed to focus all the garlic's energy into bulb growth. The scapes can be eaten raw or cooked.[15][19]

Production trends[edit]

Garlic is grown globally, but China is by far the largest producer of garlic, with around 19 million tonnes (42 billion pounds) grown annually, accounting for over 79% of world output. India (5.2%) and South Korea (1.7%) follow, with Egypt (0.9%) in fourth place and the United States (where garlic is grown in every state except for Alaska) in tenth place (0.7%).[20] This leaves 11% of global garlic production in countries that each produce less than 2% of global output. Much of the garlic production in the United States is centered in Gilroy, California, which calls itself the "garlic capital of the world".[21]

Uses[edit]

Culinary uses[edit]

Garlic is widely used around the world for its pungent flavor as a seasoning or condiment.

The garlic plant's bulb is the most commonly used part of the plant. With the exception of the single clove types, garlic bulbs are normally divided into numerous fleshy sections called cloves. Garlic cloves are used for consumption (raw or cooked) or for medicinal purposes. They have a characteristic pungent, spicy flavor that mellows and sweetens considerably with cooking.[23]

Other parts of the garlic plant are also edible. The leaves and flowers (bulbils) on the head (spathe) are sometimes eaten. They are milder in flavor than the bulbs,[3] and are most often consumed while immature and still tender. Immature garlic is sometimes pulled, rather like a scallion, and sold as "green garlic".[24] When green garlic is allowed to grow past the "scallion" stage, but not permitted to fully mature, it may produce a garlic "round", a bulb like a boiling onion, but not separated into cloves like a mature bulb.[25] It imparts a garlic flavor and aroma in food, minus the spiciness. Green garlic is often chopped and stir-fried or cooked in soup or hotpot in Southeast Asian (i.e. Vietnamese, Thai, Lao, Cambodian, Singaporean) and Chinese cookery, and is very abundant and low-priced. Additionally, the immature flower stalks (scapes) of the hardneck and elephant types are sometimes marketed for uses similar to asparagus in stir-fries.[9]

Inedible or rarely eaten parts of the garlic plant include the "skin" covering each clove and root cluster. The papery, protective layers of "skin" over various parts of the plant are generally discarded during preparation for most culinary uses, though in Korea immature whole heads are sometimes prepared with the tender skins intact.[26] The root cluster attached to the basal plate of the bulb is the only part not typically considered palatable in any form.

Garlic is a fundamental component in many or most dishes of various regions, including eastern Asia, South Asia, Southeast Asia, the Middle East, northern Africa, southern Europe, and parts of South and Central America. The flavor varies in intensity and aroma with the different cooking methods. It is often paired with onion, tomato, or ginger. The parchment-like skin is much like the skin of an onion, and is typically removed before using in raw or cooked form. An alternative is to cut the top off the bulb, coat the cloves by dribbling olive oil (or other oil-based seasoning) over them, and roast them in an oven. Garlic softens and can be extracted from the cloves by squeezing the (root) end of the bulb, or individually by squeezing one end of the clove. In Korea, heads of garlic are heated over the course of several weeks; the resulting product, called black garlic, is sweet and syrupy, and is now being sold in the United States, United Kingdom and Australia.

Garlic may be applied to different kinds of bread, usually in a medium of butter or oil, to create a variety of classic dishes, such as garlic bread, garlic toast, bruschetta, crostini and canapé.

Green garlic
Garlic cloves pickled by simply storing them in vinegar in a refrigerator. This also yields garlic-infused vinegar to use in recipes or as a condiment.[27]

Oils can be flavored with garlic cloves. These infused oils are used to season all categories of vegetables, meats, breads and pasta. Garlic, along with fish sauce, chopped fresh chilis, lime juice, sugar and water, is a basic essential item in dipping fish sauce, a highly used dipping sauce condiment used in Indochina. In East and Southeast Asia, chili oil with garlic is a popular dipping sauce, especially for meat and seafood. Tuong ot toi Viet Nam (Vietnam Chili Garlic Sauce) is a highly popular condiment and dip across North America and Asia.

In some cuisines, the young bulbs are pickled for three to six weeks in a mixture of sugar, salt, and spices. In eastern Europe, the shoots are pickled and eaten as an appetizer. Laba garlic, prepared by soaking garlic in vinegar, is a type of pickled garlic served with dumplings in northern China to celebrate the Chinese New Year.[2]

Lightly smoked garlic is becoming increasingly popular in British and European cuisine. It is particularly prized for stuffing poultry and game, and in soups and stews. In both these cases it is important to utilize the undiscarded skin, as much of the smoke flavor is situated there, rather than in the cloves themselves.

Immature scapes are tender and edible. They are also known as "garlic spears", "stems", or "tops". Scapes generally have a milder taste than the cloves. They are often used in stir frying or braised like asparagus.[19] Garlic leaves are a popular vegetable in many parts of Asia. The leaves are cut, cleaned, and then stir-fried with eggs, meat, or vegetables.

Mixing garlic with egg yolks and olive oil produces aioli. Garlic, oil, and a chunky base produce skordalia. Blending garlic, almond, oil, and soaked bread produces ajoblanco. Tzatziki, yogurt mixed with garlic and salt is a common sauce in Eastern Mediterranean cuisines.

Garlic powder has a different taste from fresh garlic. If used as a substitute for fresh garlic, 1/8 teaspoon of garlic powder is equivalent to one clove of garlic.

Storage[edit]

Domestically, garlic is stored warm [above 18 °C (64 °F)] and dry to keep it dormant (lest it sprout). It is traditionally hung; softneck varieties are often braided in strands called plaits or grappes. Peeled cloves may be stored in wine or vinegar in the refrigerator.[28] Commercially, garlic is stored at 0 °C (32 °F), in a dry, low-humidity environment. Garlic will keep longer if the tops remain attached.[9]

Garlic is often kept in oil to produce flavored oil; however, the practice requires measures to be taken to prevent the garlic from spoiling which may include rancidity and growth of Clostridium botulinum.[29] Acidification with a mild solution of vinegar minimizes bacterial growth.[29] Refrigeration does not assure the safety of garlic kept in oil, requiring use within one month to avoid bacterial spoilage.[29]

Historical use[edit]

Harvesting garlic, from Tacuinum sanitatis, 15th century (Bibliothèque nationale)

The use of garlic in China dates back to 2000 BC.[2] It was consumed by ancient Greek and Roman soldiers, sailors, and rural classes (Virgil, Ecologues ii. 11), and, according to Pliny the Elder (Natural History xix. 32), by the African peasantry. Galen eulogized it as the "rustic's theriac" (cure-all) (see F. Adams' Paulus Aegineta, p. 99), and Alexander Neckam, a writer of the 12th century (see Wright's edition of his works, p. 473, 1863), discussed it as a palliative for the heat of the sun in field labor. Garlic was placed by the ancient Greeks on the piles of stones at crossroads, as a supper for Hecate (Theophrastus, Characters, The Superstitious Man). According to Pliny, garlic and onions were invoked as deities by the Egyptians at the taking of oaths.

In his Natural History, Pliny gives a list of scenarios in which garlic was considered beneficial (N.H. xx. 23). Dr. T. Sydenham valued it as an application in confluent smallpox, and, says Cullen (Mat. Med. ii. p. 174, 1789), found some dropsies cured by it alone.

Garlic was rare in traditional English cuisine (though it is said to have been grown in England before 1548) and has been a much more common ingredient in Mediterranean Europe.[30] When the English came to America, they brought their antigarlic attitude with them, and it took almost three hundred years - likely because of continuing puritanism influence - for this viewpoint to diminish, though it was used in medicine.[30] Translations of the c. 1300 Assize of Weights and Measures indicate a passage as dealing with standardized units of garlic production, sale, and taxation—the hundred of 15 ropes of 15 heads each[31]—but the Latin version of the text refers to herring rather than garlic.[32]

Garlic was used as an antiseptic to prevent gangrene during World Wars I and II.[33]

In the typical serving size of 1–3 cloves (3–9 g), garlic provides no significant nutritional value with the content of all essential nutrients below 10% of the Daily Value (DV) (right table).[34] When expressed per 100 grams, garlic contains several nutrients in rich amounts (> 20% DV), including vitamins B6 and C, and the dietary minerals, manganese and phosphorus. Per 100 gram serving, garlic is also a good source (10–19% DV) of certain B vitamins including thiamine (Vitamin B1), and pantothenic acid (Vitamin B5), as well as certain dietary minerals including calcium, iron, and zinc (right table).

Research[edit]

Cardiovascular[edit]

A 2013 meta-analysis concluded that garlic preparations may effectively lower total cholesterol by 11–23 mg/dL and LDL cholesterol by 3–15 mg/dL in adults with high cholesterol if taken for longer than two months. The same analysis found that garlic had a marginally positive effect on HDL cholesterol and no significant effect on blood triglyceride levels, and that garlic preparations were generally well tolerated with very few side effects.[35]

A 2012 Cochrane review of two randomized controlled trials found that the effect of garlic supplementation on blood pressure is unclear and that there is insufficient evidence to determine if garlic lowers cardiovascular death and disease rates in people with hypertension.[36]

As garlic may reduce platelet aggregation,[37][38] patients taking anticoagulant medication are cautioned about consuming garlic.[39]

Cancer[edit]

A 2014 meta-analysis of observational epidemiological studies found that garlic consumption is associated with a lower risk of stomach cancer in the Korean population.[40] Similarly, a 2013 meta-analysis of case-control studies and cohort studies found limited evidence suggesting an association between higher garlic consumption and a lower risk of prostate cancer. However, the association was only significant in the case-control studies and the authors noted there was evidence of publication bias.[41]

Common cold[edit]

A 2014 report in the Cochrane Database of Systematic Reviews found no useful clinical trials on the common cold had been conducted with garlic, allowing no conclusions about whether an effect exists.[42] It did reference one trial of the garlic extract, allicin, but found that trial to be too poor in design to state any effect of allicin had occurred.[42] Other reviews concluded a similar absence of high-quality evidence for garlic having any significant effect on the common cold.[39][43]

Other uses[edit]

The sticky juice within the bulb cloves is used as an adhesive in mending glass and porcelain.[3] An environmentally benign garlic-derived polysulfide product is approved for use in the European Union (under Annex 1 of 91/414) and the UK as a nematicide and insecticide, including for use for control of cabbage root fly and red mite in poultry.[44]

Garlic along with cinnamon is used as a fish and meat preservative, and displays antimicrobial property at temperatures as high as 120 degree Celsius; the combination can also be used to preserve fried and deep fried foods, and in the future might be used in an inner layer of plastic.[45][46][47][48]

Adverse effects and toxicology[edit]

Garlic is known to cause bad breath (halitosis) and body odor, described as a pungent "garlicky" smell to sweat. This is caused by allyl methyl sulfide (AMS). AMS is a volatile liquid which is absorbed into the blood during the metabolism of garlic-derived sulfur compounds; from the blood it travels to the lungs[2] (and from there to the mouth, causing bad breath; see garlic breath) and skin, where it is exuded through skin pores. Washing the skin with soap is only a partial and imperfect solution to the smell. Studies have shown sipping milk at the same time as consuming garlic can significantly neutralize bad breath.[49] Mixing garlic with milk in the mouth before swallowing reduced the odor better than drinking milk afterward.[49] Plain water, mushrooms and basil may also reduce the odor; the mix of fat and water found in milk, however, was the most effective.[49]

The green, dry "folds" in the center of the garlic clove are especially pungent. The sulfur compound allicin, produced by crushing or chewing fresh garlic, produces other sulfur compounds: ajoene, allyl polysulfides, and vinyldithiins.[2] Aged garlic lacks allicin, but may have some activity due to the presence of S-allylcysteine.

Some people suffer from allergies to garlic and other species of Allium.[2] Symptoms can include irritable bowel, diarrhea, mouth and throat ulcerations, nausea, breathing difficulties, and, in rare cases, anaphylaxis. Garlic-sensitive patients show positive tests to diallyl disulfide, allylpropyldisulfide, allylmercaptan and allicin, all of which are present in garlic. People who suffer from garlic allergies are often sensitive to many other plants, including onions, chives, leeks, shallots, garden lilies, ginger, and bananas.

Several reports of serious burns resulting from garlic being applied topically for various purposes, including naturopathic uses and acne treatment, indicate care must be taken for these uses, usually testing a small area of skin using a very low concentration of garlic.[50] On the basis of numerous reports of such burns, including burns to children, topical use of raw garlic, as well as insertion of raw garlic into body cavities, is discouraged. In particular, topical application of raw garlic to young children is not advisable.[51] The side effects of long-term garlic supplementation are largely unknown, and no FDA-approved study has been performed. Possible side effects include gastrointestinal discomfort, sweating, dizziness, allergic reactions, bleeding, and menstrual irregularities.[6]

Some breastfeeding mothers have found, after consuming garlic, that their babies can be slow to feed, and have noted a garlic odor coming from them.[52][53]

If higher-than-recommended doses of garlic are taken with anticoagulant medications, this can lead to a higher risk of bleeding.[54] Garlic may interact with warfarin, antiplatelets, saquinavir, antihypertensives, calcium channel blockers, quinolone family of antibiotics such as ciprofloxacin, and hypoglycemic drugs, as well as other medications.[52] Alliums might be toxic to cats or dogs.[55]

Spiritual and religious uses[edit]

Garlic has been regarded as a force for both good and evil. In Europe, many cultures have used garlic for protection or white magic, perhaps owing to its reputation as a potent preventative medicine. Central European folk beliefs considered garlic a powerful ward against demons, werewolves, and vampires. To ward off vampires, garlic could be worn, hung in windows, or rubbed on chimneys and keyholes.[56][57]

In Iranian countries which celebrate Nowruz (Persian calendar New Year) such as Iran, the Caucasus countries, Afghanistan, and Central Asian countries such as Tajikistan and Uzbekistan, garlic is one of the items in a Seven-Seen table, a traditional New Year's display.

In Islam, it is generally recommended not to eat raw garlic prior to going to the mosque, since the odor could distract other Muslims during their prayer.[58] Muhammad himself disliked eating garlic.[59]

In both Hinduism and Jainism, garlic is thought to stimulate and warm the body and to increase one's desires. Some devout Hindus generally avoid using garlic and the related onion in the preparation of foods, while less devout followers may only observe this for religious festivities and events. Followers of the Jain religion avoid eating garlic and onion on a daily basis.

In some Buddhist traditions, garlic – along with the other five "pungent spices" – is understood to stimulate sexual and aggressive drives to the detriment of meditation practice. In Mahayana Buddhism, monks and nuns are not allowed to consume garlic or other pungent spices such as chili, which are deemed as being "earthly pleasures" and are viewed as promoting aggression due to their spiciness and pungency.

Properties[edit]

Alliin, a sulfur-containing compound found in garlic.

Fresh or crushed garlic yields the sulfur-containing compounds alliin, ajoene, diallyl polysulfides, vinyldithiins, S-allylcysteine, and enzymes, saponins, flavonoids, and Maillard reaction products, which are not sulfur-containing compounds.

The composition of the bulbs is approximately 84.09% water, 13.38% organic matter, and 1.53% inorganic matter, while the leaves are 87.14% water, 11.27% organic matter, and 1.59% inorganic matter.[60]

The phytochemicals responsible for the sharp flavor of garlic are produced when the plant's cells are damaged. When a cell is broken by chopping, chewing, or crushing, enzymes stored in cell vacuoles trigger the breakdown of several sulfur-containing compounds stored in the cell fluids (cytosol).[citation needed] The resultant compounds are responsible for the sharp or hot taste and strong smell of garlic. Some of the compounds are unstable and continue to react over time. Among the members of the onion family, garlic has by far the highest concentrations of initial reaction products, making garlic much more potent than onion, shallot, or leeks.[61] Although many humans enjoy the taste of garlic, these compounds are believed to have evolved as a defensive mechanism, deterring animals such as birds, insects, and worms from eating the plant.[62] Because of this, people throughout history have used garlic to keep away insects such as mosquitoes and slugs.[citation needed]

A large number of sulfur compounds contribute to the smell and taste of garlic. Allicin has been found to be the compound most responsible for the "hot" sensation of raw garlic. This chemical opens thermo-transient receptor potential channels that are responsible for the burning sense of heat in foods. The process of cooking garlic removes allicin, thus mellowing its spiciness.[62] Allicin, along with its decomposition products diallyl disulfide and diallyl trisulfide, are major contributors to the characteristic odor of garlic, with other allicin-derived compounds, such as vinyldithiins and ajoene.[2] Because of its strong odor, garlic is sometimes called the "stinking rose". When eaten in quantity, garlic may be strongly evident in the diner's sweat and garlic breath the following day. This is because garlic's strong-smelling sulfur compounds are metabolized, forming allyl methyl sulfide. Allyl methyl sulfide (AMS) cannot be digested and is passed into the blood. It is carried to the lungs and the skin, where it is excreted. Since digestion takes several hours, and release of AMS several hours more, the effect of eating garlic may be present for a long time.[2]

The well-known phenomenon of "garlic breath" is allegedly alleviated by eating fresh parsley.[63] The herb is, therefore, included in many garlic recipes, such as pistou, persillade, and the garlic butter spread used in garlic bread.

Because of the AMS in the bloodstream, it is believed by some to act as a mosquito repellent, but no clinically reported evidence suggests it is actually effective.[64]

Abundant sulfur compounds in garlic are also responsible for turning garlic green or blue during pickling and cooking. Under these conditions (i.e. acidity, heat) the sulfur-containing compound alliinase react with common amino acids to make pyrroles, clusters of carbon-nitrogen rings.[65][66] These rings can be linked together into polypyrrole molecules. Ring structures absorb particular wavelengths of light and thus appear colored. The two-pyrrole molecule looks red, the three-pyrrole molecule looks blue and the four-pyrrole molecule looks green (like chlorophyll, a tetrapyrrole). Like chlorophyll, the pyrrole pigments are safe to eat.[67]

Upon cutting, similar to a color change in onion caused by reactions of amino acids with sulfur compounds,[68] garlic can turn green.[69][70][71]
