'''Cinnamon''' is the aromatic, inner [[bark]] of certain bushy, [[tree#evergreen versus deciduous|evergreen]] [[shrub]]s or [[small tree]]s of the ''Cinnamomum'' genus of the laurel family ([[Lauraceae]]), especially ''C. verum'' (or ''C. zeylanicum''), ''C. aromaticum'' (or ''C. cassia''), and ''C. loureirii''), that is dried, ground, and used as a spice. The term is also used for the plants yielding this bark and for the spice itself.

'''Cinnamon''' is the aromatic, inner [[bark]] of certain bushy, tropical, [[tree#evergreen versus deciduous|evergreen]] [[shrub]]s or [[small tree]]s of the ''Cinnamomum'' genus of the laurel family ([[Lauraceae]]), especially ''C. verum'' (or ''C. zeylanicum''), ''C. aromaticum'' (or ''C. cassia''), and ''C. loureirii''), that is dried, ground, and used as a spice. The term is also used for the culinary name of the spice and for the [[plant]]s yielding this bark, and in particular for ''C. verum'', which is known as "true cinnamon" or ''Ceylon cinnamon''.

Most of the spice sold as cinnamon in the United States and Canada (where true cinnamon is still generally unknown) is actually cassia from ''C. aromaticum''. In some cases, cassia is labeled "Chinese cinnamon" to distinguish it from the more expensive true cinnamon, which is the preferred form of the spice used in [[Mexico]] and [[Europe]].

The name cinnamon comes from Greek ''kinnámōmon'', from Phoenician and akin to Hebrew ''qinnâmôn'', itself ultimately from a Malaysian language (cf. Malay and Indonesian ''kayu manis'', which means sweet wood).

==Cinnamonum==
 +
'''''Cinnamomum''''' is a [[genus]] of evergreen trees and shrubs belonging to the Laurel family, [[Lauraceae]]. The species of ''Cinnamomum'' have aromatic oils in their [[Leaf|leaves]] and bark. The genus contains over 300 species, distributed in tropical and subtropical regions of [[North America]], [[Central America]], [[South America]], [[Asia]], [[Oceania ecozone|Oceania]], and [[Australasia ecozone|Australasia]].
 +
 +
Notable ''Cinnamomum'' species include Cinnamon (''Cinnamomum verum'' or ''C. zeylanicum'', also known as "true cinnamon" or Ceylon Cinnamon), [[Cassia]] (''C. aromaticum'' or ''C. cassia''), [[Camphor Laurel]] (''C. camphora''), [[Saigon Cinnamon]] (''C. loureiroi'', also known as Vietnamese cinnamon, Vietnamese cassia, or Saigon cassia), [[Malabathrum]] (''C. tamala'', also known as ''C. tejpata''; ''tejpat'' or ''tej pat'' in [[Hindi]]; or, inaccurately, "[[Bay leaf|Indian bay leaf]]").

===''Cinnamomum verum''===
(''Cinnamomum verum'', synonym ''C. zeylanicum'') is a small [[evergreen]] [[tree]] 10-15 meters (32.8-49.2 feet) tall, belonging to the family [[Lauraceae]], native to [[Sri Lanka]] and Southern [[India]]. The bark is widely used as a [[spice]].

Popularly labelled simply as cinnamon  or as Ceylon cinnamon, ''Cinnamomum verum'' (synonym ''C. zeylanicum'') is a small [[tree#evergreen versus deciduous|evergreen]] [[tree]] 10-15 meters (32.8-49.2 feet) tall, which is native to [[Sri Lanka]] and Southern [[India]]. The bark is widely used as a spice.

The [[leaf|leaves]] are [[ovate]]-oblong in shape, 7-18 cm (2.75-7.1 inches) long. The [[flower]]s, which are arranged in [[panicle]]s, have a greenish color, and have a rather disagreeable odor. The [[fruit]] is a purple one-centimetre [[berry]] containing a single [[seed]].

Its flavor is due to an aromatic [[essential oil]] that makes up 0.5 to 1% of its composition. This oil is prepared by roughly pounding the bark, [[macerating]] it in sea-water, and then quickly [[distillation|distilling]] the whole. It is of a golden-yellow color, with the characteristic odor of cinnamon and a very hot aromatic taste. The pungent [[taste]] and [[scent]] come from cinnamic [[aldehyde]] or [[cinnamaldehyde]] and, by the absorption of [[oxygen]] as it ages, it darkens in color and develops resinous compounds. Chemical components of the essential oil include [[ethyl cinnamate]], [[eugenol]], [[cinnamaldehyde]], beta-[[caryophyllene]], [[linalool]], and [[methyl chavicol]].

Cinnamon is harvested by growing the tree for two years and then [[coppice|coppicing]] it. The next year a dozen or so shoots will form from the roots. These shoots are then stripped of their [[bark]], which is left to dry. Only the thin (0.5 mm) inner bark is used; the outer woody portion is removed, leaving meter long cinnamon strips that curl into rolls ("quills") on drying; each dried quill comprises strips from numerous shoots packed together. These quills are then cut to 5-10 cm long pieces for sale.

Cinnamon comes from [[Sri Lanka]], and the tree also is grown commercially at [[Tellicherry]] in southern [[India]], [[Java island|Java]], [[Sumatra]], the [[West Indies]], [[Brazil]], [[Vietnam]], [[Madagascar]], [[Zanzibar]], and [[Egypt]]. Sri Lanka cinnamon is a very thin smooth bark, with a light-yellowish brown color, a highly fragrant aroma.

===Cassia or ''Cinnamonum aromaticum''===
 +
'''Cassia''' (''Cinnamomum aromaticum'', synonym ''C. cassia''), is an evergreen tree native to southern [[China]] and [[Indochina|mainland Southeast Asia]] west to [[Myanmar]]. Like its close relative, ''Cinnamomum zeylanicum'', also known as "true cinnamon" or "Ceylon cinnamon," it is used primarily for its aromatic bark, which is used as a [[spice]], often under the [[culinary name]] of "cinnamon." Cassia's flavor, however, is less delicate than that of true cinnamon; for this reason the less expensive cassia is sometimes called "bastard cinnamon." The buds are also used as a spice, especially in India and in Ancient Rome.
  
The name cinnamon comes from Greek ''kinnámōmon'', from Phoenician and akin to Hebrew ''qinnâmôn'', itself ultimately from a Malaysian language, cf. Malay and Indonesian ''kayu manis'' which means sweet wood.
+
The Cassia tree grows to 10-15 m tall, with grayish bark, and hard elongated [[leaf|leaves]] 10-15 cm long, that have a decidedly reddish color when young.  
  
==Cinnamonum==
+
Whole branches and small trees are harvested for cassia bark, unlike the small shoots used in the production of true cinnamon; this gives cassia bark a much thicker and rougher texture than that of true cinnamon.
'''''Cinnamomum''''' is a genus of evergreen trees and shrubs belonging to the Laurel family, [[Lauraceae]]. The species of ''Cinnamomum'' have aromatic oils in their [[Leaf|leaves]] and bark. The genus contains over 300 species, distributed in tropical and subtropical regions of [[North America]], [[Central America]], [[South America]], [[Asia]], [[Oceania ecozone|Oceania]] and [[Australasia ecozone|Australasia]].
 
  
Notable ''Cinnamomum'' species include [[Cinnamon]] (''Cinnamomum verum'' or ''C. zeylanicum'', also known as "true cinnamon" or Ceylon Cinnamon), [[Cassia]] (''C. aromaticum'' or ''C. cassia''), [[Camphor Laurel]] (''C. camphora''), [[Saigon Cinnamon]] (''C. loureiroi'', also known as Vietnamese cinnamon, Vietnamese cassia, or Saigon cassia), [[Malabathrum]] (''C. tamala'', also known as ''C. tejpata''; ''tejpat'' or ''tej pat'' in [[Hindi]]; or, inaccurately, "[[Bay leaf|Indian bay leaf]]").
+
Cassia is produced in both mainland and island [[Southeast Asia]]. Up to the 1960s, [[Vietnam]] was the world's most important producer of Saigon Cinnamon, a species so closely related to cassia that it was often marketed as cassia (or, in North America, "cinnamon"). Because of the disruption caused by the [[Vietnam War]], however, production of cassia in the highlands of the [[Indonesia]]n island of [[Sumatra]] was increased to meet demand, and Indonesia remains one of the main exporters of cassia today. Saigon Cinnamon, only having become available again in the United States since the early 21st century, has an intense flavor and aroma and a higher percentage of essential oils than Indonesian cassia. Tung Hing, a rarer form of cassia produced in [[China]], is said to be sweeter and more peppery than Indonesian cassia.
  
==Cassia or ''Cinnamonum aromaticum''==
+
Cassia bark (both powdered and in whole, or "stick" form) is used as a flavoring agent, for candies, desserts, baked goods, and meat; it is specified in many [[curry]] recipes, where cinnamon is less suitable. Cassia is sometimes added to true cinnamon but is a much thicker, coarser product. Cassia is sold as pieces of bark or as neat quills or sticks.

===Cinnamon and cassia===
  
===Production and uses===
+
The name ''cinnamon'' is correctly used to refer to Ceylon Cinnamon, also known as "true cinnamon" (from the botanical name ''C. verum'').  However, the related species ''Cinnamomum aromaticum'' (Cassia or bastard cinnamon) and [[Cinnamomum burmannii]] (Indonesia cinnamon) are sometimes sold labeled as cinnamon. Ceylon cinnamon, using only the thin inner bark, has a finer, less dense and more crumbly texture, and is considered to be less strong than cassia. Cassia is generally a medium to light reddish brown, is hard and woody in texture, and is thicker (2-3 mm thick), as all of the layers of bark are used.
[[Image:zimtbaum.jpg|left|thumb|Young Cassia tree, Indonesia]]
 
Cassia is a close relative to the [[cinnamon]] (''Cinnamomum zeylanicum'', or "true cinnamon"), [[Saigon Cinnamon]] (''Cinnamomum loureiroi'', also known as "Vietnamese Cinnamon"), Camphor laurel (''[[Cinnamomum camphora]]''), [[Malabathrum]] (''Cinnamomum tamala'') and [[Cinnamomum burmannii]] trees. As with these species, the dried bark of cassia is used as a spice. Cassia's flavour, however, is less delicate than that of true cinnamon; for this reason the less expensive cassia is sometimes called "bastard cinnamon".  
 
  
Whole branches and small trees are harvested for cassia bark, unlike the small shoots used in the production of [[cinnamon]]; this gives cassia bark a much thicker and rougher texture than that of true cinnamon.

Most of the cinnamon sold in supermarkets in the [[United States]] is actually cassia.
  
Most of the spice sold as [[cinnamon]] in the United States and Canada (where true cinnamon is still generally unknown) is actually cassia.  In some cases, cassia is labeled "Chinese cinnamon" to distinguish it from the more expensive [[cinnamon|true cinnamon]] (''Cinnamomum zeylanicum''), which is the preferred form of the spice used in [[Mexico]] and [[Europe]] [http://64.233.187.104/search?q=cache:3JiMVHVu2msJ:www.detnews.com/2002/food/0201/14/e06-377804.htm+%22there%27s+true+cinnamon,%22&hl=en].
+
The two barks when whole are easily distinguished, and their microscopic characteristics are also quite distinct. Cinnamon sticks (or quills) have many thin layers and can easily be made into powder using a coffee or spice grinder, whereas cassia sticks are much harder, usually are made up of one thick layer, and are capable of damaging a spice or coffee grinder if one attempts to grind them without first breaking them into very small pieces.  
"Indonesian cinnamon" can also refer to [[Cinnamomum burmannii]], which is also
 
commonly sold in the United States, labeled only as cinnamon.

+
It is a bit harder to tell powdered cinnamon from powdered cassia. When powdered bark is treated with [[tincture of iodine]] (a test for [[Starch#Tests|starch]]), little effect is visible in the case of pure cinnamon of good quality, but when [[cassia]] is present a deep-blue tint is produced, the intensity of the coloration depending on the proportion of cassia.
  
Cassia bark (both powdered and in whole, or "stick" form) is used as a flavouring agent, for candies, desserts, baked goods, and meat; it is specified in many [[curry]] recipes, where cinnamon is less suitable. Cassia is sometimes added to true cinnamon but is a much thicker, coarser product. Cassia is sold as pieces of bark (as pictured below) or as neat quills or sticks. Cassia sticks can be distinguished from true Cinnamon sticks in the following manner: Cinnamon sticks have many thin layers and can easily be made into powder using a coffee or spice grinder, whereas Cassia sticks are extremely hard, are usually made up of one thick layer and can break an electric spice or coffee grinder if one attempts to grind them without first breaking them into very small pieces.
+
True cinnamon is also sometimes confused with [[Malabathrum]] (''Cinnamomum tamala'') and [[Saigon Cinnamon]] (''Cinnamomum loureiroi'').
  
Cassia buds, although rare, are also occasionally used as a spice. They resemble cloves in appearance and flavor.[http://www.theepicentre.com/Spices/cassia.html]<sup>[http://www.uni-graz.at/~katzer/pictures/cinn_06.jpg photo]</sup>

[[Image:2005cinnamon_%28canella%29.PNG|thumb|right|Cinnamon ([[canella]]) output in 2005]]
 +
Cinnamon has been known from remote antiquity, and it was so highly prized among ancient nations that it was regarded as a gift fit for monarchs and other great potentates. It was imported to [[Egypt]] from [[China]] as early as 2000 B.C.E., and is mentioned in the [[Bible]] in [[Exodus]] 30:23, where [[Moses]] is commanded to use both sweet cinnamon ([[Hebrew language|Hebrew]] קִנָּמוֹן, qinnāmôn) and [[cassia]], and in [[Book of Proverbs|Proverbs]] 7:17-18, where the lover's bed is perfumed with [[myrrh]], [[aloe]] and cinnamon. It is also alluded to by [[Herodotus]] and other classical writers. It was commonly used on funeral pyres in [[Rome]], and the Emperor [[Nero]] is said to have burned a year's supply of cinnamon at the funeral for his wife [[Poppaea Sabina]], in 65 C.E..
  
====Health benefits and risks====
+
In the [[Middle Ages]], the source of cinnamon was a mystery to the Western world. Arab traders brought the spice via overland trade routes to [[Alexandria]] in Egypt, where it was bought by [[Venice|Venetian]] traders from Italy who held a [[monopoly]] on the spice trade in Europe.  The disruption of this trade by the rise of other Mediterranean powers such as the [[Mameluk dynasty|Mameluks Sultans]] and the [[Ottoman Empire]] was one of many factors that led Europeans to search more widely for other routes to Asia.

Cassia (called ròu gùi; [[wiktionary:肉|]][[wiktionary:桂|桂]] in Chinese) is used in [[traditional Chinese medicine]], where it is considered one of the [[Chinese herbology#50 fundamental herbs|50 fundamental herbs]].
 
  
A 2003 study published in the DiabetesCare journal<ref>[http://care.diabetesjournals.org/cgi/content/full/26/12/3215 Cinnamon Improves Glucose and Lipids of People With Type 2 Diabetes]</ref> followed Type 2 diabetics ingesting 1, 3 or 6 grams of cassia daily. Those taking 6 grams shows changes after 20 days, and those taking lesser doses showed changes after 40 days. Regardless of the amount of cassia taken, they reduced their mean fasting serum glucose levels 18–29%, their triglyceride levels 23–30%, their LDL cholesterol 7–27%, and their total cholesterol 12–26%, over others taking placebos.  
+
Portuguese traders finally discovered Ceylon ([[Sri Lanka]]) at the end of the fifteenth century, and restructured the traditional production of cinnamon by the ''[[salagama]]'' caste. The Portuguese established a fort on the island in 1518, and protected their own monopoly for over a hundred years.
  
The effects, which may even be produced by brewing a tea from cassia bark, may also be beneficial for non-diabetics to prevent and control elevated glucose and blood lipid levels.  Cassia's effects on enhancing [[insulin sensitivity]] appear to be mediated by [[polyphenol]]s [http://www.ars.usda.gov/research/publications/publications.htm?seq_no_115=176887].  Despite these findings, cassia should not be used in place of [[anti-diabetic drug]]s, unless blood glucose levels are closely monitored and its use is combined with a strictly controlled diet and exercise program.
+
Dutch traders finally dislodged the Portuguese by allying with the inland Ceylon kingdom of [[Kandy]].  They established a trading post in 1638, took control of the factories by 1640, and expelled all remaining Portuguese by 1658. "The shores of the island are full of it", a Dutch captain reported, "and it is the best in all the Orient: when one is downwind of the island, one can still smell cinnamon eight [[league (unit)|leagues]] out to sea" (Braudel 1984, p. 215).
  
There is also much anecdotal evidence that consumption of cassia has a strong effect in lowering blood pressure, making it potentially useful to those suffering from [[hypertension]]. The USDA has three ongoing studies that are monitoring the blood pressure effect.
+
The [[Dutch East India Company]] continued to overhaul the methods of harvesting in the wild, and eventually began to cultivate its own trees.
  
Though the spice has been used for thousands of years, there is concern that there is as yet no knowledge about the potential for toxic buildup of the [[fat-soluble]] components in cassia, as anything fat-soluble could potentially be subject to toxic buildup. There are no concluded long term clinical studies on the use of cassia for health reasons.
+
The British took control of the island from the Dutch in 1796.  However, the importance of the monopoly of Ceylon was already declining, as cultivation of the cinnamon tree spread to other areas, the more common cassia bark became more acceptable to consumers, and [[coffee]], [[tea]], [[sugar]] and [[chocolate]] began to outstrip the popularity of traditional spices.
  
European health agencies have warned against consuming high amounts of cassia, due to a toxic component called [[coumarin]].<ref>http://www.npr.org/templates/story/story.php?storyId=6672644</ref>

Cinnamon is the aromatic, inner bark of certain bushy, tropical, evergreen shrubs or small trees of the Cinnamomum genus of the laurel family (Lauraceae), especially C. verum (or C. zeylanicum), C. aromaticum (or C. cassia), and C. loureirii), that is dried, ground, and used as a spice. The term is also used for the culinary name of the spice and for the plants yielding this bark, and in particular for C. verum, which is known as "true cinnamon" or Ceylon cinnamon.

Most of the spice sold as cinnamon in the United States and Canada (where true cinnamon is still generally unknown) is actually cassia from C. aromaticum. In some cases, cassia is labeled "Chinese cinnamon" to distinguish it from the more expensive true cinnamon, which is the preferred form of the spice used in Mexico and Europe.

The name cinnamon comes from Greek kinnámōmon, from Phoenician and akin to Hebrew qinnâmôn, itself ultimately from a Malaysian language (cf. Malay and Indonesian kayu manis, which means sweet wood).

Cinnamonum

Cinnamomum is a genus of evergreen trees and shrubs belonging to the Laurel family, Lauraceae. The species of Cinnamomum have aromatic oils in their leaves and bark. The genus contains over 300 species, distributed in tropical and subtropical regions of North America, Central America, South America, Asia, Oceania, and Australasia.

Notable Cinnamomum species include Cinnamon (Cinnamomum verum or C. zeylanicum, also known as "true cinnamon" or Ceylon Cinnamon), Cassia (C. aromaticum or C. cassia), Camphor Laurel (C. camphora), Saigon Cinnamon (C. loureiroi, also known as Vietnamese cinnamon, Vietnamese cassia, or Saigon cassia), Malabathrum (C. tamala, also known as C. tejpata; tejpat or tej pat in Hindi; or, inaccurately, "Indian bay leaf").

Cinnamomum verum

Popularly labelled simply as cinnamon or as Ceylon cinnamon, Cinnamomum verum (synonym C. zeylanicum) is a small evergreen tree 10-15 meters (32.8-49.2 feet) tall, which is native to Sri Lanka and Southern India. The bark is widely used as a spice. The leaves are ovate-oblong in shape, 7-18 cm (2.75-7.1 inches) long. The flowers, which are arranged in panicles, have a greenish color, and have a rather disagreeable odor. The fruit is a purple one-centimeter berry containing a single seed.

Its flavor is due to an aromatic essential oil that makes up 0.5 to 1% of its composition. This oil is prepared by roughly pounding the bark, macerating it in sea-water, and then quickly distilling the whole. It is of a golden-yellow color, with the characteristic odor of cinnamon and a very hot aromatic taste. The pungent taste and scent come from cinnamic aldehyde or cinnamaldehyde and, by the absorption of oxygen as it ages, it darkens in color and develops resinous compounds. Chemical components of the essential oil include ethyl cinnamate, eugenol, cinnamaldehyde, beta-caryophyllene, linalool, and methyl chavicol.

Cinnamomum verum, from Koehler's Medicinal-Plants (1887)

Cinnamon is harvested by growing the tree for two years and then coppicing it. The next year a dozen or so shoots will form from the roots. These shoots are then stripped of their bark, which is left to dry. Only the thin (0.5 mm) inner bark is used; the outer woody portion is removed, leaving meter long cinnamon strips that curl into rolls ("quills") on drying; each dried quill comprises strips from numerous shoots packed together. These quills are then cut to 5-10 cm long pieces for sale.

Cinnamon comes from Sri Lanka, and the tree also is grown commercially at Tellicherry in southern India, Java, Sumatra, the West Indies, Brazil, Vietnam, Madagascar, Zanzibar, and Egypt. Sri Lanka cinnamon is a very thin smooth bark, with a light-yellowish brown color, a highly fragrant aroma.

Cassia or Cinnamonum aromaticum

Cassia (Cinnamomum aromaticum, synonym C. cassia), is an evergreen tree native to southern China and mainland Southeast Asia west to Myanmar. Like its close relative, Cinnamomum zeylanicum, also known as "true cinnamon" or "Ceylon cinnamon," it is used primarily for its aromatic bark, which is used as a spice, often under the culinary name of "cinnamon." Cassia's flavor, however, is less delicate than that of true cinnamon; for this reason the less expensive cassia is sometimes called "bastard cinnamon." The buds are also used as a spice, especially in India and in Ancient Rome.

The Cassia tree grows to 10-15 m tall, with grayish bark, and hard elongated leaves 10-15 cm long, that have a decidedly reddish color when young.

Whole branches and small trees are harvested for cassia bark, unlike the small shoots used in the production of true cinnamon; this gives cassia bark a much thicker and rougher texture than that of true cinnamon.

Cassia is produced in both mainland and island Southeast Asia. Up to the 1960s, Vietnam was the world's most important producer of Saigon Cinnamon, a species so closely related to cassia that it was often marketed as cassia (or, in North America, "cinnamon"). Because of the disruption caused by the Vietnam War, however, production of cassia in the highlands of the Indonesian island of Sumatra was increased to meet demand, and Indonesia remains one of the main exporters of cassia today. Saigon Cinnamon, only having become available again in the United States since the early 21st century, has an intense flavor and aroma and a higher percentage of essential oils than Indonesian cassia. Tung Hing, a rarer form of cassia produced in China, is said to be sweeter and more peppery than Indonesian cassia.

Cassia bark (both powdered and in whole, or "stick" form) is used as a flavoring agent, for candies, desserts, baked goods, and meat; it is specified in many curry recipes, where cinnamon is less suitable. Cassia is sometimes added to true cinnamon but is a much thicker, coarser product. Cassia is sold as pieces of bark or as neat quills or sticks.

Cinnamon and cassia

The name cinnamon is correctly used to refer to Ceylon Cinnamon, also known as "true cinnamon" (from the botanical name C. verum). However, the related species Cinnamomum aromaticum (Cassia or bastard cinnamon) and Cinnamomum burmannii (Indonesia cinnamon) are sometimes sold labeled as cinnamon. Ceylon cinnamon, using only the thin inner bark, has a finer, less dense and more crumbly texture, and is considered to be less strong than cassia. Cassia is generally a medium to light reddish brown, is hard and woody in texture, and is thicker (2-3 mm thick), as all of the layers of bark are used.

Most of the cinnamon sold in supermarkets in the United States is actually cassia.

The two barks when whole are easily distinguished, and their microscopic characteristics are also quite distinct. Cinnamon sticks (or quills) have many thin layers and can easily be made into powder using a coffee or spice grinder, whereas cassia sticks are much harder, usually are made up of one thick layer, and are capable of damaging a spice or coffee grinder if one attempts to grind them without first breaking them into very small pieces.

It is a bit harder to tell powdered cinnamon from powdered cassia. When powdered bark is treated with tincture of iodine (a test for starch), little effect is visible in the case of pure cinnamon of good quality, but when cassia is present a deep-blue tint is produced, the intensity of the coloration depending on the proportion of cassia.

True cinnamon is also sometimes confused with Malabathrum (Cinnamomum tamala) and Saigon Cinnamon (Cinnamomum loureiroi).

History

Cinnamon (canella) output in 2005

Cinnamon has been known from remote antiquity, and it was so highly prized among ancient nations that it was regarded as a gift fit for monarchs and other great potentates. It was imported to Egypt from China as early as 2000 B.C.E., and is mentioned in the Bible in Exodus 30:23, where Moses is commanded to use both sweet cinnamon (Hebrew קִנָּמוֹן, qinnāmôn) and cassia, and in Proverbs 7:17-18, where the lover's bed is perfumed with myrrh, aloe and cinnamon. It is also alluded to by Herodotus and other classical writers. It was commonly used on funeral pyres in Rome, and the Emperor Nero is said to have burned a year's supply of cinnamon at the funeral for his wife Poppaea Sabina, in 65 C.E.

In the Middle Ages, the source of cinnamon was a mystery to the Western world. Arab traders brought the spice via overland trade routes to Alexandria in Egypt, where it was bought by Venetian traders from Italy who held a monopoly on the spice trade in Europe. The disruption of this trade by the rise of other Mediterranean powers such as the Mameluks Sultans and the Ottoman Empire was one of many factors that led Europeans to search more widely for other routes to Asia.

Portuguese traders finally discovered Ceylon (Sri Lanka) at the end of the fifteenth century, and restructured the traditional production of cinnamon by the salagama caste. The Portuguese established a fort on the island in 1518, and protected their own monopoly for over a hundred years.

Dutch traders finally dislodged the Portuguese by allying with the inland Ceylon kingdom of Kandy. They established a trading post in 1638, took control of the factories by 1640, and expelled all remaining Portuguese by 1658. "The shores of the island are full of it", a Dutch captain reported, "and it is the best in all the Orient: when one is downwind of the island, one can still smell cinnamon eight leagues out to sea" (Braudel 1984, p. 215).

The Dutch East India Company continued to overhaul the methods of harvesting in the wild, and eventually began to cultivate its own trees.

The British took control of the island from the Dutch in 1796. However, the importance of the monopoly of Ceylon was already declining, as cultivation of the cinnamon tree spread to other areas, the more common cassia bark became more acceptable to consumers, and coffee, tea, sugar and chocolate began to outstrip the popularity of traditional spices.

According to FAO, Indonesia produced almost 40% of the world cinnamon (canella) output in 2005 followed by China, India and Vietnam.

History

In classical times, four types of cinnamon were distinguished (and often confused):

  • Cassia (Hebrew qəṣi`â), the bark of Cinnamomum iners from Arabia and Ethiopia
  • Cinnamon proper (Hebrew qinnamon), the bark of Cinnamomum zeylanicum from Sri Lanka
  • Malabathrum or Malobathrum (from Sanskrit तमालपत्त्रम्, tamālapattram, literally "dark-tree leaves"), Cinnamomum malabathrum from the North of India
  • Serichatum, Cinnamomum aromaticum from Seres, that is, China.

In Exodus 30:23-4, Moses is ordered to use both sweet cinnamon (Kinnamon) and cassia (qəṣî`â) together with myrrh, sweet calamus (qənê-bosem, literally cane of fragrance) and olive oil to produce a holy oil to anoint the Ark of the Covenant. Psalm 45, 8, mentions the garments of Torah scholars that smell of myrrh, aloes and cassia.

The first Greek reference to kasia is found in a poem by Sappho in the 7th century B.C.E.

According to Herodotus, both cinnamon and cassia grow in Arabia, together with incense, myrrh, and ladanum, and are guarded by winged serpents. The phoenix builds its nest from cinnamon and cassia. But Herodotus mentions other writers that see the home of Dionysos, e.g. India, as the source of cassia. While Theophrastus gives a rather good account of the plants, but a curious method for harvesting (worms eat away the wood and leave the bark behind), Dioscorides seems to confuse the plant with some kind of water-lily.

Pliny (nat. 12, 86-87) gives a fascinating account of the early spice trade across the Red Sea in "rafts without sails or oars", obviously using the trade winds, that costs Rome 100 million sesterces each year. According to Pliny, a pound (the Roman pound, 327 g) of cassia, cinnamon or serichatum cost up to 300 denars, the wage of ten month's labour. Diocletian's Edict on Maximum Prices from 301 C.E. gives a price of 125 denars for a pound of cassia, while an agricultural labourer earned 25 denars per day.

The Greeks used kásia or malabathron to flavour wine, together with absinth (Artemisia absinthia). Pliny mentions cassia as a flavouring agent for wine as well (Plin. nat. 14, 107f.). Malabathrum leaves (folia) were used in cooking and for distilling an oil used in a caraway-sauce for oysters by the Roman gourmet Gaius Gavius Apicius (de re coquinaria I, 29, 30; IX, 7). Malabathrum is among the spices that, according to Apicius, any good kitchen should contain.

Egyptian recipes for kyphi, an aromatic used for burning, included cinnamon and cassia from Hellenistic times onwards. The gifts of Hellenistic rulers to temples sometimes included cassia and cinnamon as well as incense, myrrh, and Indian incense (kostos), so we can conclude that the Greeks used it in this way too.

The famous Commagenum, an unguent produced in Commagene in present-day eastern Turkey was made from goose-fat and aromatised with cinnamon oil and spikenard (Nardostachys jatamansi). Malobrathum from Egypt (Dioscorides I, 63) was based on cattle-fat and contained cinnamon as well; one pound cost 300 denars. The Roman poet Martial (VI, 55) makes fun of Romans who drip unguents, smell of cassia and cinnamon taken from a bird's nest and look down on him who does not smell at all.

Cinnamon, as a warm and dry substance, was believed by doctors in ancient times to cure snakebites, freckles, the common cold, and kidney troubles, among other ailments.


Health benefits and risks

Dried cassia bark

Cassia (called ròu gùi; in Chinese) is used in traditional Chinese medicine, where it is considered one of the 50 fundamental herbs.

A 2003 study published in the DiabetesCare journal[1] followed Type 2 diabetics ingesting 1, 3 or 6 grams of cassia daily. Those taking 6 grams shows changes after 20 days, and those taking lesser doses showed changes after 40 days. Regardless of the amount of cassia taken, they reduced their mean fasting serum glucose levels 18–29%, their triglyceride levels 23–30%, their LDL cholesterol 7–27%, and their total cholesterol 12–26%, over others taking placebos.

The effects, which may even be produced by brewing a tea from cassia bark, may also be beneficial for non-diabetics to prevent and control elevated glucose and blood lipid levels. Cassia's effects on enhancing insulin sensitivity appear to be mediated by polyphenols [1]. Despite these findings, cassia should not be used in place of anti-diabetic drugs, unless blood glucose levels are closely monitored and its use is combined with a strictly controlled diet and exercise program.

There is also much anecdotal evidence that consumption of cassia has a strong effect in lowering blood pressure, making it potentially useful to those suffering from hypertension. The USDA has three ongoing studies that are monitoring the blood pressure effect.

Though the spice has been used for thousands of years, there is concern that there is as yet no knowledge about the potential for toxic buildup of the fat-soluble components in cassia, as anything fat-soluble could potentially be subject to toxic buildup. There are no concluded long term clinical studies on the use of cassia for health reasons.

European health agencies have warned against consuming high amounts of cassia, due to a toxic component called coumarin.[2]

European health agencies recently have warned against consuming high amounts of cassia, due to a toxic component called coumarin (Harris 2007). This is contained in much lower dosages in Ceylon cinnamon and in Cinnamomum burmannii. Coumarin is known to cause liver and kidney damage in high concentrations.


Uses

Quills of true cinnamon bark

Cinnamon bark is widely used as a spice. It is principally employed in cookery as a condiment and flavouring material, being largely used in the preparation of some kinds of desserts, chocolate, spicy candies, tea, hot cocoa and liqueurs. In the Middle East, it is often used in savoury dishes of chicken and lamb. In the United States, cinnamon and sugar are often used to flavour cereals, bread-based dishes, and fruits, especially apples; a cinnamon-sugar mixture is even sold separately for such purposes. Cinnamon can also be used in pickling. Cinnamon bark is one of the few spices which can be consumed directly.

In medicine it acts like other volatile oils and once had a reputation as a cure for colds. It has also been used to treat diarrhea and other problems of the digestive system.[3] Cinnamon is high in antioxidant activity (PMID 16190627, PMID 10077878). The essential oil of cinnamon also has antimicrobial properties (PMID 16104824), which aid in the preservation of certain foods.[4]

In the media, "cinnamon" has been reported to have remarkable pharmacological effects in the treatment of type II diabetes. However, the plant material used in the study (PMID 14633804) was actually cassia, as opposed to true cinnamon. Please refer to cassia's medicinal uses for more information about its health benefits. Cinnamon has traditionally been used to treat toothache and fight bad breath and its regular use is believed to stave off common cold and aid digestion.[5]

Cinnamon is used in the system of Thelemic Magick for the invocation of Apollo, according to the correspondences listed in Aleister Crowley's work Liber 777.

Cinnamon is also used as an insect repellent.[6]
