Overview

Brief Summary

Allium sativum, (cultivated) garlic, is a species of monocot, bulb-forming perennial. Relatives include onions and shallots (A. cepa), and leeks (A. ampeloprasum). Garlic is not found in the wild—“sativum” means “cultivated”—but appears to have originated in mountainous regions in Central Asia (Brewster 2008).

Garlic has been cultivated for over 5000 years. Diverse representations in Mesopotamian writings from ~3000 B.C. and Egyptian art dating to 2700 B.C suggest that garlic was already widely used (Block 2010, Fritsch and Friesen 2002). Hippocrates, Galen, Pliny the Elder, and Dioscorides recommend garlic for conditions including parasites, respiratory problems, poor digestion, and low energy. It is described in Chinese writings from A.D. 510 (Hahn 1996), and is mentioned in the Bible and the Koran (Block 2010).

Garlic bulbs contain separate fleshy sections (cloves), each covered with a papery skin (tunic). The plants produce a leafless flower stem (a scape), but the flowers are sterile and produce bulbils (small cloves) rather than seeds; the species is propagated clonally from cloves and bulbils (Block 2010). Hundreds of cultivars are divided into two subspecies: 1) Hardneck garlic (A sativum ssp. ophioscorodon); and 2) Softneck garlic (A. sativum ssp. sativum, Block 2010).

Garlic has historically been grown for both culinary and medicinal purposes. Bulbs are most commonly used, but leaves, scapes, and bulbils are also eaten. Garlic is frequent in the cuisines of Asia, the Middle East, the Mediterranean, and South and Central America. It has traditionally been used to treat pulmonary problems, coughs, and tuberculosis. Recent works describe numerous traditional medicinal and ritual uses and literary depictions (Wikipedia 2011, Block 2010, Hahn 1996), including the Central European practice of using garlic to fend off evil spirits and vampires (Koch 1996).

Garlic produces various sulfur compounds that, together with their breakdown products, yield a characteristic pungent taste and odor, which may persist on the breath and body for up to 30 hours as garlic is metabolized (Block 2010). These compounds have documented antimicrobial and antifungal effects. Allicin, derived from garlic, combats fungal infections and parasites, lowers blood cholesterol, treats arterosclerosis, and promotes circulatory function (Block 2010, Reuter et al. 1996). Garlic preparations are used to treat insect stings and improve scar healing (Block 2010). Epidemiological studies suggest that dietary garlic consumption lowers the risk of various cancers (Reuter et al. 1996).

Global garlic production in 2008 topped 22 million metric tons, harvested from nearly 1.4 million hectares (FAOSTAT 2011). China produces over ¾ of the yield, followed by India, South Korea, Russia, Egypt, and the U.S, where California leads production. The town of Gilroy, California, bills itself “Garlic Capital of the World” and celebrates annual garlic festivals (Boriss and Geissler 2011, USDA/ERS 2000).

Garlic has escaped from cultivation in many U.S. states and Canadian provinces (USDA PLANTS 2011), but generally remains localized. Several related “garlic” species— “wild-,” “crow-” “field-” and “meadow garlic” and “garlic chives” (A. ursinum, A. vineale, A. oleraceum, A. canadense, and A. tuberosum, respectively)—are, however, weedy or invasive in Europe and North America.

Garlic plants are closely related to and similar to onions and they have a similar, but stronger odor. The leaves of garlic plants are neither inflated like onion leaves nor tubular like those of bunching onions. Instead, they are flat, with a crease down the middle and are held erect in two opposite ranks. Most varieties stand about 1-2 ft (0.3-0.6 m) tall at maturity. Garlic plants produce an underground bulb that usually is divisible into 6-20 segments, called cloves. Hardneck garlic (a.k.a. rocambole, top-setting garlic, and serpent garlic) is Allium sativum var. ophioscorodon. It produces a flower stalk that coils like a snake, then straightens out and bears clusters of pea-sized bulblets or "bulbils" that are like miniature garlic bulbs. Garlic is not known from the wild but probably was derived from Allium longicuspis, which is native to central Asia. Garlic has been cultivated for more than 5,000 years.
Some authorities place the onions, garlics, leeks and their relatives in a family of their own, the Alliaceae, and others put them in the lily family, the Liliaceae. There are about 400 species in the genus Allium, including some magnificent ornamentals. Well known members of the genus include: onions (A. cepa), bunching or green onions (A. fistulosum), chives (A. schoenoprasum), garlic chives (A. tuberosum), and A. ampeloprasum, which is divided into three horticultural groups: The Porrum Group, which includes leeks, grown for their stems; the Ampeloprasum Group, which includes elephant garlic, grown for its large, mild garlic-like bulb; and the Kurrat Group, which includes kurrat, a small plant grown for its leaves and rarely seen outside Egypt and the Middle East.

General Ecology

Culture

Light: Garlic will do best in full sun but can be grown with satisfactory results in partial shade.

Moisture: Garlic can tolerate periods without rain, but best results come from plants that receive regular watering.

Hardiness: Garlic is grown as an annual, started from cloves broken out of the bulb. Garlic is best planted in the fall and allowed to overwinter in the ground, to be harvested the following summer. In mild climates garlic will grow all winter; in cold climates areas, it will go dormant in the winter, and should be mulched.

Propagation: Garlic almost never produces fertile seeds. It must be propagated vegetatively. Divide garlic bulbs into individual cloves and plant them, flattened end down, about 2-3 in (5-7.6 cm) deep and 3-4 in (7.6-10 cm) apart. Rocambole can be started from cloves or from the little bulblets that are produced on the top of the looping stem, but the cloves grow faster.

Usage

Garlic is the strongest flavored member of the onion family. Until quite recently, most civilizations used it medicinally and only their poor people ate it, while the priests and upper class citizens scorned its strong odor.

Harvest garlic and rocambole when the tops fall over and turn brown. Dry the bulbs (but not in direct sun) for a week, then store in a dark, dry area, or braid the still-attached stems for a decorative and edible wreath. Bulbs to be saved for later planting can be stored in a plastic bag in the refrigerator for up to 8 months.

Rocambole bulbils as well as the bulbs are used in the same was as garlic. In addition, the immature flower shoots, called garlic spears, are a delicacy in the Far East, and the young leaves can be used like chives. Many consider rocambole to be more flavorful than regular garlic, but it is harder to grow, and usually the bulbs are smaller, and they have a shorter storage life.

For a real taste sensation, try baking or roasting whole garlic bulbs until soft and creamy.

Garlic contains compounds that are antibacterial, antifungal and reduce blood clotting. In order for the active ingredient that gives garlic its characteristic odor and its therapeutic effects to be released, the garlic clove must be cut or crushed. This releases an enzyme that causes the formation of allicin, the component responsible for garlic's odor and medicinal activity.

Wikipedia

Garlic

Allium sativum, commonly known as garlic, is a species in the onion genus, Allium. Its close relatives include the onion, shallot, leek, chive,[1] and rakkyo.[2] Garlic has been used throughout history for both culinary and medicinal purposes. The garlic plant's bulb is the most commonly used part of the plant. With the exception of the single clove types, the bulb is divided into numerous fleshy sections called cloves. The cloves are used for consumption (raw or cooked), or for medicinal purposes, and have a characteristic pungent, spicy flavor that mellows and sweetens considerably with cooking.[3] The leaves and flowers (bulbils) on the head (spathe) are also edible, and being milder in flavor than the bulbs,[2] they are most often consumed while immature and still tender. Additionally, the immature flower stalks (scapes) of the hardneck and elephant types are sometimes marketed for uses similar to asparagus in stir-fries.[4] 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.[5] The root cluster attached to the basal plate of the bulb is the only part not typically considered palatable in any form. The sticky juice within the bulb cloves is used as an adhesive in mending glass and porcelain in China.[2] Dating back over 6,000 years, it is native to central Asia, and has long been a staple in the Mediterranean region, as well as a frequent seasoning in Asia, Africa, and Europe. The irrational fear of garlic is alliumphobia.[6]

Origin and major types

Bulbils

The ancestry of cultivated garlic is not definitively established. According to Zohary and Hopf,[7] "A difficulty in the identification of its wild progenitor is the sterility of the cultivars", though it is thought to be descendent from the species Allium longicuspis, which grows wild in central and southwestern Asia.[4][8] Allium sativum grows in the wild in areas where it has become naturalised. The "wild garlic", "crow garlic", and "field garlic" of Britain are members of the species Allium ursinum, Allium vineale, and Allium oleraceum, respectively. 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.[9] One of the best-known "garlics", the 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.

There are a number of garlics with Protected Geographical Status in Europe; these include:

Varieties

Garlic can come in many varieties, including fresh, frozen, dried, fermented (black garlic) and shelf stable products (in tubes or jars). While botanist classify garlic under the umbrella of the species, Allium sativum, there are also two main subspecies.

  • Ophioscorodon, or hard necked garlic, includes porcelain garlics, rocambole garlic, and purple stripe garlics.
  • Sativum, or soft necked garlic, includes artichoke garlic, silverskin garlic, and creole garlic.

[10]

Cultivation

Garlic is easy to grow and can be grown year-round in mild climates. While sexual propagation of garlic is indeed possible, nearly all of the garlic in cultivation is done so asexually, by planting individual cloves in the ground.[4] In cold climates, cloves are planted in the ground in the fall, about six weeks before the soil freezes, and harvested in late spring.[11] Garlic plants are usually very hardy, and are not attacked by many pests or diseases. Garlic plants are said to repel rabbits and moles.[2] Two of the major pathogens that attack garlic are nematodes and white rot disease, which remain in the soil indefinitely once the ground has become infected.[4] Garlic also can suffer from pink root, a typically nonfatal disease that stunts the roots and turns them pink or red.[12] Garlic plants can be grown close together, leaving enough room for the bulbs to mature, and are easily grown in containers of sufficient depth. When selecting garlic for planting, it is important to pick large heads from which to separate cloves. Large cloves, along with proper spacing in the planting bed, will also improve head 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.[4]

There are different types 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.[13][14]

Garlic scapes are removed to focus all the garlic's energy into bulb growth. The scapes are sold separately for cooking.[11][15]

Production trends

Garlic output in 2005

Garlic is grown globally, but China is by far the largest producer of garlic, with approximately 10.5 million tonnes (23 billion pounds) grown annually, accounting for over 77% of world output. India (4.1%) and South Korea (2%) follow, with Egypt and Russia (1.6%) tied in fourth place and the United States (where garlic is grown in every state except for Alaska) in sixth place (1.4%).[16] This leaves 16% 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".[citation needed]

Uses

Culinary uses

Garlic being crushed using a garlic press

Garlic is widely used around the world for its pungent flavor as a seasoning or condiment. It 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 flavour 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 fermented at high temperature; 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 breads to create a variety of classic dishes, such as garlic bread, garlic toast, bruschetta, crostini and canapé.

Garlic being rubbed onto a slice of bread

Oils can be flavored with garlic cloves. These infused oils are used to season all categories of vegetables, meats, breads and pasta.

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.

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.[15] 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.

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

Ready peeled garlic cloves sold in a plastic container

Domestically, garlic is stored warm [above 18°C (64°F)] and dry to keep it dormant (so it does not sprout). It is traditionally hung; softneck varieties are often braided in strands called plaits or grappes. Garlic is often kept in oil to produce flavoured oil; however, the practice requires measures to be taken to prevent the garlic from spoiling. Untreated garlic kept in oil can support the growth of deadly Clostridium botulinum. Refrigeration will not assure the safety of garlic kept in oil. Peeled cloves may be stored in wine or vinegar in the refrigerator.[17]

Commercially prepared oils are widely available, but when preparing and storing garlic-infused oil at home, there is a risk of botulism if the product is not stored properly. To reduce this risk, the oil should be refrigerated and used within one week. Manufacturers add acids and/or other chemicals to eliminate the risk of botulism in their products.[18] Two outbreaks of botulism related to garlic stored in oil have been reported.[19][20]

Commercially, garlic is stored at 0°C (32°F), in a dry, low-humidity environment.[21] Garlic will keep longer if the tops remain attached.[4]

Historical use

Garlic has been used as both food and medicine in many cultures for thousands of years, dating at least as far back as when the Giza pyramids were built. Garlic is still grown in Egypt, but the Syrian variety is the kind most esteemed now (see Rawlinson's Herodotus, 2.125).

Garlic is mentioned in the Bible and the Talmud. Hippocrates, Galen, Pliny the Elder, and Dioscorides all mention the use of garlic for many conditions, including parasites, respiratory problems, poor digestion, and low energy. Its use in China was first mentioned in A.D. 510.

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 eulogizes it as the "rustic's theriac" (cure-all) (see F. Adams' PAegineta, p. 99), and Alexander Neckam, a writer of the 12th century (see Wright's edition of his works, p. 473, 1863), recommends it as a palliative for the heat of the sun in field labor.

In the account of Korea's establishment as a nation, gods were said to have given mortal women with bear and tiger temperaments an immortal's black garlic before mating with them.[citation needed][vague] This is a genetically unique, six-clove garlic that was to have given the women supernatural powers and immortality. This garlic is still cultivated in a few mountain areas today.

In his Natural History, Pliny gives an exceedingly long list of scenarios in which it 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. Early in the 20th century, it was sometimes used in the treatment of pulmonary tuberculosis or phthisis.

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

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. Garlic was placed by the ancient Greeks on the piles of stones at crossroads, as a supper for Hecate (Theophrastus, Characters, The Superstitious Man). A similar practice of hanging garlic, lemon and red chilli at the door or in a shop to ward off potential evil, is still very common in India.[22] According to Pliny, garlic and onions were invoked as deities by the Egyptians at the taking of oaths. (Pliny also stated garlic demagnetizes lodestones, which is not factual.)[23] The inhabitants of Pelusium, in lower Egypt (who worshiped the onion), are said to have had an aversion to both onions and garlic as food.

To prevent the plant from running to leaf, Pliny (N.H. xix. 34) advised bending the stalk downward and covering with earth; seeding, he observes, may be prevented by twisting the stalk (by "seeding", he most likely meant the development of small, less potent bulbs).

In in vitro studies, garlic has been found to have antibacterial, antiviral, and antifungal activity. However, these actions are less clear in vivo. Garlic is also claimed to help prevent heart disease (including atherosclerosis, high cholesterol, and high blood pressure) and cancer.[24] Garlic is used to prevent certain types of cancer, including stomach and colon cancers. In fact, countries where garlic is consumed in higher amounts, because of traditional cuisine, have been found to have a lower prevalence of cancer.[25] Animal studies, and some early investigational studies in humans, have suggested possible cardiovascular benefits of garlic. A Czech study found garlic supplementation reduced accumulation of cholesterol on the vascular walls of animals.[26] Another study had similar results, with garlic supplementation significantly reducing aortic plaque deposits of cholesterol-fed rabbits.[27] Another study showed supplementation with garlic extract inhibited vascular calcification in human patients with high blood cholesterol.[28] The known vasodilative effect of garlic is possibly caused by catabolism of garlic-derived polysulfides to hydrogen sulfide in red blood cells (RBCs), a reaction that is dependent on reduced thiols in or on the RBC membrane. Hydrogen sulfide is an endogenous cardioprotective vascular cell-signaling molecule.[29]

Although these studies showed protective vascular changes in garlic-fed subjects, a randomized clinical trial funded by the National Institutes of Health (NIH) in the United States and published in the Archives of Internal Medicine in 2007 found the consumption of garlic in any form did not reduce blood cholesterol levels in patients with moderately high baseline cholesterol levels.[30][31]

According to the Heart.org, "despite decades of research suggesting that garlic can improve cholesterol profiles, a new NIH-funded trial found absolutely no effects of raw garlic or garlic supplements on LDL, HDL, or triglycerides... The findings underscore the hazards of meta-analyses made up of small, flawed studies and the value of rigorously studying popular herbal remedies". In an editorial regarding the initial report's findings, two physicians from Weill Cornell Medical College of Cornell University, pointed out that there may "be effects of garlic on atherosclerosis specifically that were not picked up in the study".[32]

Allium sativum has been found to reduce platelet aggregation[33][34][35][36] and hyperlipidemia.[36][37][38]

In 2007, the BBC reported Allium sativum may have other beneficial properties, such as preventing and fighting the common cold.[39] This assertion has the backing of long tradition in herbal medicine, which has used garlic for hoarseness and coughs.[40] The Cherokee also used it as an expectorant for coughs and croup.[41]

Garlic is also alleged to help regulate blood sugar levels. Regular and prolonged use of therapeutic amounts of aged garlic extracts lower blood homocysteine levels and has been shown to prevent some complications of diabetes mellitus.[42][43] People taking insulin should not consume medicinal amounts of garlic without consulting a physician.

In 1858, Louis Pasteur observed garlic's antibacterial activity, and it was used as an antiseptic to prevent gangrene during World War I and World War II.[44] More recently, it has been found from a clinical trial that a mouthwash containing 2.5% fresh garlic shows good antimicrobial activity, although the majority of the participants reported an unpleasant taste and halitosis.[45]

Garlic cloves are used as a remedy for infections (especially chest problems), digestive disorders, and fungal infections such as thrush.[46][47]

Garlic has been found to enhance thiamin absorption, and therefore reduces the likelihood for developing the thiamin deficiency beriberi.[48]

In 1924, it was found to be an effective way to prevent scurvy, because of its high vitamin C content.[48]

Garlic has been used reasonably successfully in AIDS patients to treat Cryptosporidium in an uncontrolled study in China.[49] It has also been used by at least one AIDS patient to treat toxoplasmosis, another protozoal disease.[50]

Garlic supplementation in rats, along with a high protein diet, has been shown to boost testosterone levels.[51]

A 2010 double-blind, parallel, randomised, placebo-controlled trial, involving 50 patients whose routine clinical records in general practice documented treated but uncontrolled hypertension, concluded, "Our trial suggests that aged garlic extract is superior to placebo in lowering systolic blood pressure similarly to current first line medications in patients with treated but uncontrolled hypertension."[52]

Adverse effects and toxicology

Garlic is known for causing halitosis, as well as causing sweat to have a pungent 'garlicky' smell, which is caused by allyl methyl sulfide (AMS). AMS is a gas which is absorbed into the blood during the metabolism of garlic; from the blood it travels to the lungs[citation needed] (and from there to the mouth, causing bad 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.[53] Mixing garlic with milk in the mouth before swallowing reduced the odor better than drinking milk afterward.[53] Plain water, mushrooms and basil may also reduce the odor; the mix of fat and water found in milk, however, was the most effective.[53]

Raw garlic is more potent; cooking garlic reduces the effect.[citation needed] 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 sulfides, and vinyldithiins. Aged garlic lacks allicin, but may have some activity due to the presence of S-allylcysteine.

In a rat study, allicin, was found to be an activator of TRPA1. The neurons released neurotransmitters in the spinal cord to generate pain signals and released neuropeptides at the site of sensory nerve activation, resulting in vasodilation, as well as inflammation.[54] Allicin is released only by cruching or chewing raw garlic and cannot be formed from cooked garlic.

Some people suffer from allergies to garlic and other plants in the allium family. 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 will often be sensitive to many plants in the lily family (Liliaceae), including onions, garlic, chives, leeks, shallots, garden lilies, ginger, and bananas.

Garlic can also cause indigestion, nausea, vomiting, and diarrhea.[55] It thins the blood (as does aspirin);[56] this had caused very high quantities of garlic and garlic supplements to be linked with an increased risk of bleeding, particularly during pregnancy and after surgery and childbirth,[55][57] although culinary quantities are safe for consumption. 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.[58] 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.[59] The side effects of long-term garlic supplementation, if any exist, are largely unknown, and no FDA-approved study has been performed. However, garlic has been consumed for several thousand years without any adverse long-term effects, suggesting modest quantities of garlic pose, at worst, minimal risks to normal individuals. Possible side effects include gastrointestinal discomfort, sweating, dizziness, allergic reactions, bleeding, and menstrual irregularities.[57] The safety of garlic supplements had not been determined for children.;[60] some breastfeeding mothers have found their babies slow to feed and have noted a garlic odour coming from their baby when they have consumed garlic.[55][60]

Garlic may interact with warfarin, antiplatelets, saquinavir, antihypertensives, calcium channel blockers, and hypoglycemic drugs, as well as other medications.[55] Members of the alium family might be toxic to cats or dogs.[61] Some degree of liver toxicity has been demonstrated in rats, particularly in extremely large quantities exceeding those that a rat would consume under normal situations.[62]

Properties

When crushed, Allium sativum yields allicin, an antibiotic[63] and antifungal compound (phytoncide). It has been claimed that it can be used as a home remedy to help speed recovery from strep throat or other minor ailments because of its antibiotic properties[citation needed]. It also contains the sulfur-containing compounds alliin, ajoene, diallylsulfide, dithiin, S-allylcysteine, and enzymes, B vitamins, proteins, minerals, saponins, flavonoids, and Maillard reaction products, which are not sulfur-containing compounds. Furthermore, a phytoalexin (allixin) was found, a nonsulfur compound with a γ-pyrone skeleton structure with antioxidant effects, antimicrobial effects,[64] antitumor promoting effects,[65] inhibition of aflatoxin B2 DNA binding,[65] and neurotrophic effects. Allixin showed an antitumor promoting effect in vivo, inhibiting skin tumor formation by TPA and DMBA initiated mice.[65] Analogs of this compound have exhibited antitumor promoting effects in in vitro experimental conditions. Herein, allixin and/or its analogs may be expected useful compounds for cancer prevention or chemotherapy agents for other diseases.

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.[66][67]

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. 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 onions, shallots, or leeks.[68] 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.[69]

A large number of sulfur compounds contribute to the smell and taste of garlic. Diallyl disulfide is believed to be an important odor component. Allicin has been found to be the compound most responsible for the "hot" sensation of raw garlic. This chemical opens thermotransient 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.[70]

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 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.

This well-known phenomenon of "garlic breath" is alleged to be alleviated by eating fresh parsley.[71] The herb is, therefore, included in many garlic recipes, such as [[pistou]], persillade, and the garlic butter spread used in garlic bread. However, since the odour results mainly from digestive processes placing compounds such as AMS in the blood, and AMS is then released through the lungs over the course of many hours, eating parsley provides only a temporary masking. One way of accelerating the release of AMS from the body is the use of a sauna.[citation needed]

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.[72]

Spiritual and religious perceptions

Garlic has been regarded as a force for both good and evil. According to Cassell's Dictionary of Superstitions, there is an Islamic myth that considers that after Satan left the Garden of Eden, garlic arose in his left footprint and onion in the right.[73] In Europe, many cultures have used garlic for protection or white magic, perhaps owing to its reputation as a potent preventative medicine.[74] Central European folk beliefs considered garlic a powerful ward against demons, werewolves, and vampires.[74] To ward off vampires, garlic could be worn, hung in windows, or rubbed on chimneys and keyholes.[75]

In both Hinduism and Jainism, garlic is considered 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 for religious festivities and events. Followers of the Jain religion avoid eating garlic and onion on a daily basis.

In connection with the odor associated with garlic, Islam views eating garlic and subsequently going to the mosque as inappropriate[76] because the smell from the mouth will irritate the fellow worshippers.
