The '''chili pepper''', or more simply just "chili", is the fruit of species of the plant ''[[Capsicum]]'' from the nightshade family, ''[[Solanaceae]]''.
The name, which is spelled differently in many regions ('''chili, chile or chilli'''), comes from [[Nahuatl language|Nahuatl]] via the [[Spanish language|Spanish]] word ''chile''. The term chili in most of the world refers exclusively to the smaller, hot types of capsicum.
The mild larger types are called ''[[bell pepper]]'' in the USA, simply ''[[capsicum|pepper]]'' in [[Britain]] and [[Ireland]], ''[[capsicum|capsicum]]'' in [[Australasia]] and ''[[paprika|paprika]]'' in many European countries.

Chili peppers and their various [[cultivar]]s originate in the [[Americas]]; they are now grown around the world because they are widely used as [[spice]]s or [[vegetable]]s in [[cuisine]], and as [[medicine]].
==History==
Chili peppers have been a part of the human diet in the Americas since at least 7500 BC and perhaps earlier. There is [[archaeological]] evidence at sites located in southwestern [[Ecuador]] that chili peppers were already well [[domesticated]] more than 6000 years ago <ref>Perry, L. ''et al''. 2007. Starch fossils and the domestication and dispersal of chili peppers (Capsicum spp. L.) in the Americas. ''Science'' 315: 986-988.</ref><ref>BBC News Online. 2007. Chillies heated ancient cuisine. Friday, 16 February. Available from: http://news.bbc.co.uk/2/hi/americas/6367299.stm. Accessed 16 February 2007.</ref>, and is one of the first cultivated crops in the Americas. Chili peppers are thought to have been domesticated at least five times by prehistoric peoples in different parts of South, Central and North America, from [[Peru]] in the south to [[Mexico]] in the north and parts of Colorado and New Mexico ([[Ancient Pueblo Peoples]]).<ref>[http://www.hort.purdue.edu/newcrop/proceedings1996/V3-479.html Bosland, P.W. 1996.

In the publication [[Svensk Botanisk Tidskrift]] (1995), Professor [[Hakon Hjelmqvist]] published an article on pre-Columbian chili peppers in Europe. In a archaeological dig in the block of St. Botulf in [[Lund]], [[archaeologists]] found a ''Capsicum frutechens'' in a layer dating to the 13th century. Hjelmqvist also claims that ''Capsicum'' was described by the Greek [[Therophrasteus]] (370-286 BC). He also mentions other antique sources. The Roman poet [[Martialis]] (around the 1st century) described "Pipervee crudum" (raw pepper) to be long and containing seeds. The description of the plants does not fit pepper, which does also not grow well in European climates. <ref>{{cite news|title=Cayennepeppar från Lunds medeltid||first=Hakon|last=Hjelmqvist|author=Hakon Hjelmqvist|work=Svensk Botanisk Tidskrift, vol 89|pages=193-}}</ref>
[[Christopher Columbus]] was one of the first Europeans to encounter them (in the [[Caribbean]]), and called them "peppers" because of their similarity in taste (though not in appearance) with the Old World [[Black pepper|peppers]] of the ''[[Piper (genus)|Piper]]'' genus. Columbus was keen to prove (incorrectly) that he had in fact opened a new direct nautical route to Asia, contrary to reality and the expert consensus of the time, and it has been speculated that he was therefore inclined to denote these new substances as "pepper" in order to associate them with the known Asian spice{{Fact|date=February 2007}}.
Chilis were cultivated around the globe after Columbus' time.<ref>Heiser Jr., C.B. 1976. Pp. 265-268 in N.W. Simmonds (ed.). ''Evolution of Crop Plants''. London: Longman.</ref> <ref>Eshbaugh, W.H. 1993. Pp. 132-139 in J. Janick and J.E. Simon (eds.). ''New Crops''. New York: Wiley.</ref> [[Diego Álvarez Chanca]], a physician on Columbus' second voyage to the West Indies in 1493, brought the first chili peppers to [[Spain]], and first wrote about their medicinal effects in 1494.
From [[Mexico]], at the time the Spanish colony that controlled commerce with Asia, chili peppers spread rapidly into the [[Philippines]] and then to [[India]], [[China]], [[Korea]] and [[Japan]] with the aid of [[Europe|European]] sailors. The new spice was quickly incorporated into the local cuisines.
An alternate sequence for chili pepper's spread has the Portuguese picking up the pepper from Spain, and thence to India, as described by [[Lizzie Collingham]] in her book ''Curry''.<ref>{{cite book | last = Collingham| first = Elizabeth | title = Curry | publisher = Oxford University Press | date = 2006 | month = February | id = ISBN 0-09-943786-4 }}</ref> The evidence provided is that the chili pepper figures heavily in the cuisine of the Goan region of India, which was the site of a Portuguese colony (e.g. [[Vindaloo]], an Indian interpretation of a Portuguese dish). Collingham also describes the journey of chili peppers from India, through Central Asia and [[Turkey]], to [[Hungary]], where it became the national spice in the form of [[paprika]].
==Species and cultivars==
[[Image:Large_Cayenne.jpg|right|thumb|220px|Cayenne chili pepper]]
{{Seealso|List of capsicum cultivars}}
The most common species of chili peppers are:
* ''[[Capsicum annuum]]'', which includes many common varieties such as [[bell pepper]]s, [[paprika]], [[jalapeño]]s, and the [[chiltepin]]
* ''[[Capsicum frutescens]]'', which includes the [[cayenne pepper|cayenne]] and [[tabasco pepper|tabasco]] peppers
* ''[[Capsicum chinense]]'', which includes the hottest peppers such as the [[naga jolokia|naga]], [[habanero]] and [[Scotch bonnet]]
* ''[[Capsicum pubescens]]'', which includes the South American [[rocoto]] peppers
* ''[[Capsicum baccatum]]'', which includes the South American [[aji pepper]]s
[[Image:Capsicum1.jpg|200px|right|thumb|Assorted [[bell pepper]] fruits from Mexico]]
Though there are only a few commonly used species, there are many [[cultivar]]s and methods of preparing chili peppers that have different common names for culinary use. [[Bell pepper]]s, for example, are the same cultivar of ''C. annuum''; immature peppers being green and mature peppers being red. In the same species are the [[jalapeño]], the [[poblano]] (when dried is referred to as ancho), [[New Mexico pepper|New Mexico]] (which is also known as chile colorado), [[Anaheim pepper|Anaheim]], [[Serrano pepper|Serrano]], and other cultivars.
[[Jamaican pepper|Jamaican]]s, [[Scotch bonnet]]s, and [[habanero]]s are common varieties of ''C. chinense''.
The species ''C. frutescens'' appears as [[chile de arbol|chiles de árbol]], aji, [[pequin]], [[tabasco pepper|tabasco]], [[cayenne pepper|cayenne]], [[cherry pepper]]s, [[malagueta]] and others.
Peppers are commonly broken down into three groupings; bell peppers, sweet peppers, and hot peppers. Most popular pepper varieties are seen as falling into one of these categories or as a cross between them.
==Intensity==
{{further|[[Capsaicin]]}}
The substances that gives chili peppers their intensity when ingested or applied topically is [[capsaicin]] (8-methyl-''N''-vanillyl-6-nonenamide) and several related chemicals, collectively called ''capsaicinoids''. Capsaicin is the primary ingredient in [[pepper spray]]. The "heat" of chili peppers is measured in [[Scoville scale|Scoville unit]]s (SHU). [[Bell pepper]]s rank at 0 (SHU), New Mexico green chilis at about 1,500 SHU, jalapeños at 3,000–6,000 SHU, and habaneros at 300,000 SHU. The former record for the hottest chili pepper was assigned by the [[Guinness Book of Records]] to the [[Red Savina pepper|Red Savina Habanero]], measuring 577,000 SHU.
[[Guinness World Records]] recently confirmed that Paul Bosland, a regents professor at New Mexico State University, had discovered the world's hottest chili pepper, the Bhut Jolokia. Bhut Jolokia (also known as Naga Jolokia, Nagahari, Bih Jolokia or Borbih Jolokia, Dorset Naga , Naga Morich amongst other names) measured 1,001,304 Scoville Heat Units. The same measurement was also seen in testing done by the Chile Pepper Institute at New Mexico State University. Originating in Assam in North Eastern India, where it was also tested by Assam based Commercial Chilli Growers Frontal Agritech at 1,041,427 Scoville Heat Units. After extensive field tests it seems that the Bhut/Bih Jolokia chili is definitely the hottest there is in the world. It must be said that close on its heels is the Naga Morich/Dorset Naga measured at 923,000 SHU. The DorFresh and dried Jolokia Podsset Naga, Naga Morich, Bhut Jolokia, Bih Jolokia are all from the same family with slight shape and flavour differences and are all extremely hot.
However, a recent report was made of a pepper from India called the [[Naga Jolokia pepper|Naga Jolokia]], measuring at 855,000 SHU. Both the Red Savina and the Naga Jolokia claims are disputed as to their validity, and lack independent verification.<ref>{{cite web | title=Red Savina and the Naga Jolokia claims | url=http://www.fiery-foods.com/dave/assam_chile2.asp}}</ref> [[as of 2006|In April 2006]], it was reported that the [[Dorset Naga pepper]], a variety of the Naga Jolokia pepper cultivated exclusively by the Peppers by Post company in Dorset, England, had been measured at 923,000 SHU by a lab used by the American Spice Trade Association.<ref>{{cite news | first=Simon | last=de Bruxelles | title=The chile so hot you need gloves | date=[[1 April]] [[2006]] | publisher=Times| url=http://www.timesonline.co.uk/article/0,,2-2113507,00.html}}</ref> For reference, pure capsaicin rates at 15,000,000-16,000,000 SHU. Subsequently BBC “Gardeners’ World” has recorded an even higher level for the Dorset Naga. As part of its 2006 programming, it ran a chili trial looking at several varieties. Heat levels were tested in a British laboratory and the Dorset Naga came in at almost 1.6 million SHU. The growers are currently waiting for details of the testing before being confident with this result.
In 2001, the Institute received seed of a chili named 'Bhut Jolokia' from a member who had collected it while visiting India. Because of poor fruit and seed set, it took Dr. Bosland several years to have sufficient seed on hand for an extensive field trial. 'Bhut Jolokia' was grown under insect-proof net cages to produce the bulk seed, and by 2004, enough seed was available for the test. Now Dr. Bosland and his colleagues were ready for a large-scale experiment. An extensive study was undertaken, with three goals:
#Compare the heat level of 'Red Savina,' 'Bhut Jolokia,' and regular habanero in a replicated field trial
#Find out whether 'Bhut Jolokia' truly had a higher heat level than 'Red Savina'
#Determine the species designation of the 'Bhut Jolokia.'
The comparison experiment was conducted in 2005 at a plant science research facility close to [[Las Cruces, New Mexico]].
==Culinary use==
[[Image:Thai peppers.jpg|left|thumb|[[Thai pepper]]]]
The chili has a long association with [[Mexican cuisine]] as later adapted into [[Tex-Mex cuisine]]. Although unknown in Asia until Europeans introduced it there, chili has also become a part of the [[Korean cuisine|Korean]], [[India]]n, [[Indonesia]]n, [[Szechuan cuisine|Szechuan]], [[Thailand|Thai]] and other cooking traditions. Its popularity has seen it adopted into many cuisines of the World.
====Chili fruit====
The fruit is eaten cooked or raw for its fiery hot flavour which is concentrated along the top of the pod. The stem end of the pod has glands which produce the capsaicin, which then flows down through the pod. The white pith, that surrounds the seeds, contains the highest concentrations of capsaicin. Removing the seeds and inner membranes is thus effective at reducing the heat of a pod.
Chili is often sold worldwide as a [[spice]] in dried and powered form. In the [[United States]], it is often made from the Mexican ''chile ancho'' variety, but with small amounts of cayenne added for heat. In the [[Southwest United States]], dried ground chili peppers, cumin, garlic and oregano is often known as [[chili powder]]. [[Chipotle]]s are dry, smoked red (ripe) jalapeños.
Chili peppers are also often used around the world to make a wide variety of sauces, known as ''[[hot sauce]]'', ''chili sauce'', or ''pepper sauce''. There are countless recipes.
Indian cooking has multiple uses for chilies, from snacks like [[bajji]] where the chilies are dipped in batter and fried to the infamously hot [[vindaloo]]. Chilies are also dried and roasted and salted for later use as a side dish for rice varieties like vadam (a kind of pappad). In [[Cuisine of Turkey|Turkish]] or [[Ottoman Empire|Ottoman]] cuisine, chilies are widely used where it is known as ''Kırmızı Biber'' (Red Pepper) or ''Acı Biber'' (Hot Pepper). [[Sambal]] is dipping sauce made from chili peppers with many other ingredients such as garlic, onion, shallots, salt, vinegar and sugar, which is very popular in Indonesia, Malaysia and Singapore.
====Chili leaves====
The leaves of the chili pepper plant, which are mildly bitter, are cooked as [[Leaf vegetable|greens]] in [[Filipino cuisine]], where they are called ''dahon ng sili'' (literally "chili leaves"). They are often used in the chicken soup dish known as ''[[tinola]]''.[http://www.tribo.org/vegetables/dahongsili.html] In Korean cuisine, the leaves are also used to produce chili pepper leaf [[kimchi]] (풋고추잎 깍두기).[http://sfood.info/cuisine/kimchi/k35.htm]
==Decoration==
[[Image:Chilis at Pike Place Market.JPG|thumb|200px|Chili peppers can also be used decoratively]]
There are entire breeds of chili pepper which are not intended for consumption at all, but are grown only for their decorative qualities, generally referred to as "ornamental peppers". Some of them are too hot for most common cooking techniques, or simply don't taste good. Some are grown for both decoration and food. Either way, they tend to have peppers of unusual shapes or colors. Examples of these include [[Thai Ornamental]], Black Pearl, Marble, [[Numex Twilight]], and the Medusa pepper. Numex Twilight is a green plant which produces fruit starting purple, then ripening to yellow, orange, and red, meaning that the plant actually has every color of the pigment [[color wheel]] except blue. Black Pearl has black leaves and round red fruit. In India, the chili, along with [[lime]] is used to ward off [[evil spirit]]s and is often seen in vehicles and in homes to that effect. It is also used to check the [[evil eye]] and remove its effects in Hinduism as people will also be asked to spit into a handful of chilies kept in that plate, which are then thrown into fire. If the chilies make a noise - as they should - then there is no case of "drishti" (evil eye); if on the other hand they don't make any sound, then the spell of the evil eye is removed in the fire.
==Popularity==
[[Image:HotPeppersinMarket.jpg|left|thumb|Scotch bonnet chili peppers in a Caribbean market]]
Chili peppers are popular in food. They are rich in [[vitamin C]] and are believed to have many beneficial effects on health. The pain caused by capsaicin stimulates the brain to produce [[endorphin]]s, natural [[opioid]]s which act as [[analgesic]]s and produce a sense of well-being. Psychologist [[Paul Rozin]] suggests that eating chilis is an example of a "constrained risk" like riding a [[roller coaster]], in which extreme sensations like pain and fear can be enjoyed because individuals know that these sensations are not actually harmful.
[[Image:Chillies drying in Kathmandu.jpg|thumb|Chili peppers drying in Kathmandu, Nepal]]
[[Bird]]s do not have the same sensitivity to capsaicin as [[mammal]]s, as [[capsaicin]] acts on a specific nerve receptor in mammals, and avian nervous systems are rather different. Chili peppers are in fact a favorite food of many birds living in the chili peppers' natural range. The flesh of the peppers provides the birds with a nutritious meal rich in [[vitamin C]]. In return, the [[seed]]s of the peppers are distributed by the birds, as they drop the seeds while eating the pods or the seeds pass through the [[digestive tract]] unharmed. This relationship is theorized to have promoted the [[evolution]] of the protect
ive capsaicin.
==Spelling and usage==
The three primary spellings are ''chili'', ''chile'' and ''chilli'', all of which are recognized by dictionaries.
* ''Chili'' is widely used, but this spelling is discouraged by some, since it is more commonly used to refer to a popular Southwestern-American dish (also known as [[chili con carne]] (literally chili with meat), the official state dish of Texas [http://www.tsl.state.tx.us/ref/abouttx/symbols.html]), as well as to the mixture of cumin and other spices ([[chili powder]]) used to flavor it. [[Chile powder]], on the other hand, refers to dried, ground chili peppers. This spelling was popularized in part by the band [[Red Hot Chili Peppers]].
* ''Chile'' is the American spelling (uncommon elsewhere) which refers specifically to this plant and its fruit. This orthography is universal in the Spanish-speaking world, although in some parts the plant and its fruit are better known as ''ají''. In the American southwest (particularly northern [[New Mexico]]), ''chile'' also denotes a thick, spicy, un-vinegared sauce, which is available in red and green varieties and which is often served over most [[w:New Mexican Food|New Mexican cuisine]].
* ''Chilli'' was the original [[Romanization]] of the [[Nahuatl language|Aztec]] word for the fruit [http://www.kakawachocolates.com/index.php?main_page=page_4] and is the preferred spelling according to the ''[[Oxford English Dictionary]]'', although it also lists ''chile'' and ''chili'' as variants.
The name of this plant bears no relation to [[Chile]], the country, which is named after the [[Quechua]] ''chin'' ("cold"), ''tchili'' ("snow"), or ''chilli'' ("where the land ends"). Chile is one of the Spanish-speaking countries where chilis are known as ''ají'', a word of [[Taíno]] origin.
There is some disagreement about whether it is proper to use the word "pepper" when discussing chili peppers because "pepper" originally referred to the genus [[Piper (genus)|Piper]], not Capsicum. Despite this dispute, a sense of ''pepper'' referring to Capsicum is supported by English dictionaries, including the [[Oxford English Dictionary]] (sense 2b of ''pepper'') and [[Merriam-Webster]] [http://www.m-w.com/cgi-bin/dictionary?book=Dictionary&va=pepper]. Furthermore, the word "pepper" is commonly used in the botanical and culinary fields in the names of different types of chili peppers.
==Nutritional value==
Red chilis are very rich in [[vitamin C]] and [[Carotene|provitamin A]]. Yellow and especially green chilis (which are essentially unripe fruit) contain a considerably lower amount of both substances. In addition, peppers are a good source of most [[B vitamins]], and [[vitamin B6]] in particular. They are very high in [[potassium]] and high in [[magnesium]] and [[iron]]. Their high vitamin C content can also substantially increase the uptake of non-heme iron from other ingredients in a meal, such as [[bean]]s and [[grain]]s. Recent studies reveal that chili peppers can have a wide range of benefits from helping alleviate pain in [[arthritis]] patients,<ref>[http://news.bbc.co.uk/1/hi/health/4993576.stm Could chilli peppers relieve pain?], [http://news.bbc.co.uk/1/hi/health/2281222.stm Chilli pepper link to arthritis pain] - [[BBC]]</ref> to acting effectively against [[cancer]] causing [[tumor]]s.<ref>[http://www.medicalnewstoday.com/healthnews.php?newsid=60504 Non-prescription Compound Found In Chillies Destroys Cancer Tumours Safely]</ref> Experts say capsaicin, the chemical that gives spicy food its kick, could be used to kill tumours with few or no side effects for the patient.<ref>[http://www.dailymail.co.uk/pages/live/articles/health/healthmain.html?in_article_id=427558&in_page_id=1774 Spicy foods 'could protect against cancer'] [[9 January]] [[2007]], [[Daily Mail]]</ref> Hot peppers, along with other [[spice]]s are also known for its ability to kill [[parasite]]s in the [[gastro-intestinal tract]]; for this reason, they are a useful dietary component in tropical regions.<ref>[http://www.discover.com/issues/sep-00/departments/featbiolog

[[Guinness World Records]] recently confirmed that Paul Bosland, a regents professor at New Mexico State University, had discovered the world's hottest chili pepper, the Bhut Jolokia. Bhut Jolokia (also known as Naga Jolokia, Nagahari, Bih Jolokia or Borbih Jolokia, Dorset Naga , Naga Morich amongst other names) measured 1,001,304 Scoville Heat Units. The same measurement was also seen in testing done by the Chile Pepper Institute at New Mexico State University. Originating in Assam in North Eastern India, where it was also tested by Assam based Commercial Chilli Growers Frontal Agritech at 1,041,427 Scoville Heat Units. After extensive field tests it seems that the Bhut/Bih Jolokia chili is definitely the hottest there is in the world. It must be said that close on its heels is the Naga Morich/Dorset Naga measured at 923,000 SHU. The DorFresh and dried Jolokia Podsset Naga, Naga Morich, Bhut Jolokia, Bih Jolokia are all from the same family with slight shape and flavour differences and are all extremely hot.
However, a recent report was made of a pepper from India called the [[Naga Jolokia pepper|Naga Jolokia]], measuring at 855,000 SHU. Both the Red Savina and the Naga Jolokia claims are disputed as to their validity, and lack independent verification.<ref>{{cite web | title=Red Savina and the Naga Jolokia claims | url=http://www.fiery-foods.com/dave/assam_chile2.asp}}</ref> [[as of 2006|In April 2006]], it was reported that the [[Dorset Naga pepper]], a variety of the Naga Jolokia pepper cultivated exclusively by the Peppers by Post company in Dorset, England, had been measured at 923,000 SHU by a lab used by the American Spice Trade Association.<ref>{{cite news | first=Simon | last=de Bruxelles | title=The chile so hot you need gloves | date=[[1 April]] [[2006]] | publisher=Times| url=http://www.timesonline.co.uk/article/0,,2-2113507,00.html}}</ref> For reference, pure capsaicin rates at 15,000,000-16,000,000 SHU. Subsequently BBC “Gardeners’ World” has recorded an even higher level for the Dorset Naga. As part of its 2006 programming, it ran a chili trial looking at several varieties. Heat levels were tested in a British laboratory and the Dorset Naga came in at almost 1.6 million SHU. The growers are currently waiting for details of the testing before being confident with this result.
In 2001, the Institute received seed of a chili named 'Bhut Jolokia' from a member who had collected it while visiting India. Because of poor fruit and seed set, it took Dr. Bosland several years to have sufficient seed on hand for an extensive field trial. 'Bhut Jolokia' was grown under insect-proof net cages to produce the bulk seed, and by 2004, enough seed was available for the test. Now Dr. Bosland and his colleagues were ready for a large-scale experiment. An extensive study was undertaken, with three goals:
#Compare the heat level of 'Red Savina,' 'Bhut Jolokia,' and regular habanero in a replicated field trial
#Find out whether 'Bhut Jolokia' truly had a higher heat level than 'Red Savina'
#Determine the species designation of the 'Bhut Jolokia.'
The comparison experiment was conducted in 2005 at a plant science research facility close to [[Las Cruces, New Mexico]].
==Culinary use==
[[Image:Thai peppers.jpg|left|thumb|[[Thai pepper]]]]
The chili has a long association with [[Mexican cuisine]] as later adapted into [[Tex-Mex cuisine]]. Although unknown in Asia until Europeans introduced it there, chili has also become a part of the [[Korean cuisine|Korean]], [[India]]n, [[Indonesia]]n, [[Szechuan cuisine|Szechuan]], [[Thailand|Thai]] and other cooking traditions. Its popularity has seen it adopted into many cuisines of the World.
====Chili fruit====
The fruit is eaten cooked or raw for its fiery hot flavour which is concentrated along the top of the pod. The stem end of the pod has glands which produce the capsaicin, which then flows down through the pod. The white pith, that surrounds the seeds, contains the highest concentrations of capsaicin. Removing the seeds and inner membranes is thus effective at reducing the heat of a pod.
Chili is often sold worldwide as a [[spice]] in dried and powered form. In the [[United States]], it is often made from the Mexican ''chile ancho'' variety, but with small amounts of cayenne added for heat. In the [[Southwest United States]], dried ground chili peppers, cumin, garlic and oregano is often known as [[chili powder]]. [[Chipotle]]s are dry, smoked red (ripe) jalapeños.
Chili peppers are also often used around the world to make a wide variety of sauces, known as ''[[hot sauce]]'', ''chili sauce'', or ''pepper sauce''. There are countless recipes.
Indian cooking has multiple uses for chilies, from snacks like [[bajji]] where the chilies are dipped in batter and fried to the infamously hot [[vindaloo]]. Chilies are also dried and roasted and salted for later use as a side dish for rice varieties like vadam (a kind of pappad). In [[Cuisine of Turkey|Turkish]] or [[Ottoman Empire|Ottoman]] cuisine, chilies are widely used where it is known as ''Kırmızı Biber'' (Red Pepper) or ''Acı Biber'' (Hot Pepper). [[Sambal]] is dipping sauce made from chili peppers with many other ingredients such as garlic, onion, shallots, salt, vinegar and sugar, which is very popular in Indonesia, Malaysia and Singapore.
====Chili leaves====
The leaves of the chili pepper plant, which are mildly bitter, are cooked as [[Leaf vegetable|greens]] in [[Filipino cuisine]], where they are called ''dahon ng sili'' (literally "chili leaves"). They are often used in the chicken soup dish known as ''[[tinola]]''.[http://www.tribo.org/vegetables/dahongsili.html] In Korean cuisine, the leaves are also used to produce chili pepper leaf [[kimchi]] (풋고추잎 깍두기).[http://sfood.info/cuisine/kimchi/k35.htm]
==Decoration==
[[Image:Chilis at Pike Place Market.JPG|thumb|200px|Chili peppers can also be used decoratively]]
There are entire breeds of chili pepper which are not intended for consumption at all, but are grown only for their decorative qualities, generally referred to as "ornamental peppers". Some of them are too hot for most common cooking techniques, or simply don't taste good. Some are grown for both decoration and food. Either way, they tend to have peppers of unusual shapes or colors. Examples of these include [[Thai Ornamental]], Black Pearl, Marble, [[Numex Twilight]], and the Medusa pepper. Numex Twilight is a green plant which produces fruit starting purple, then ripening to yellow, orange, and red, meaning that the plant actually has every color of the pigment [[color wheel]] except blue. Black Pearl has black leaves and round red fruit. In India, the chili, along with [[lime]] is used to ward off [[evil spirit]]s and is often seen in vehicles and in homes to that effect. It is also used to check the [[evil eye]] and remove its effects in Hinduism as people will also be asked to spit into a handful of chilies kept in that plate, which are then thrown into fire. If the chilies make a noise - as they should - then there is no case of "drishti" (evil eye); if on the other hand they don't make any sound, then the spell of the evil eye is removed in the fire.

Chili peppers are popular in food. They are rich in [[vitamin C]] and are believed to have many beneficial effects on health. The pain caused by capsaicin stimulates the brain to produce [[endorphin]]s, natural [[opioid]]s which act as [[analgesic]]s and produce a sense of well-being. Psychologist [[Paul Rozin]] suggests that eating chilis is an example of a "constrained risk" like riding a [[roller coaster]], in which extreme sensations like pain and fear can be enjoyed because individuals know that these sensations are not actually harmful.

[[Bird]]s do not have the same sensitivity to capsaicin as [[mammal]]s, as [[capsaicin]] acts on a specific nerve receptor in mammals, and avian nervous systems are rather different. Chili peppers are in fact a favorite food of many birds living in the chili peppers' natural range. The flesh of the peppers provides the birds with a nutritious meal rich in [[vitamin C]]. In return, the [[seed]]s of the peppers are distributed by the birds, as they drop the seeds while eating the pods or the seeds pass through the [[digestive tract]] unharmed. This relationship is theorized to have promoted the [[evolution]] of the protect
ive capsaicin.
==Spelling and usage==
The three primary spellings are ''chili'', ''chile'' and ''chilli'', all of which are recognized by dictionaries.
* ''Chili'' is widely used, but this spelling is discouraged by some, since it is more commonly used to refer to a popular Southwestern-American dish (also known as [[chili con carne]] (literally chili with meat), the official state dish of Texas [http://www.tsl.state.tx.us/ref/abouttx/symbols.html]), as well as to the mixture of cumin and other spices ([[chili powder]]) used to flavor it. [[Chile powder]], on the other hand, refers to dried, ground chili peppers. This spelling was popularized in part by the band [[Red Hot Chili Peppers]].
* ''Chile'' is the American spelling (uncommon elsewhere) which refers specifically to this plant and its fruit. This orthography is universal in the Spanish-speaking world, although in some parts the plant and its fruit are better known as ''ají''. In the American southwest (particularly northern [[New Mexico]]), ''chile'' also denotes a thick, spicy, un-vinegared sauce, which is available in red and green varieties and which is often served over most [[w:New Mexican Food|New Mexican cuisine]].
* ''Chilli'' was the original [[Romanization]] of the [[Nahuatl language|Aztec]] word for the fruit [http://www.kakawachocolates.com/index.php?main_page=page_4] and is the preferred spelling according to the ''[[Oxford English Dictionary]]'', although it also lists ''chile'' and ''chili'' as variants.
The name of this plant bears no relation to [[Chile]], the country, which is named after the [[Quechua]] ''chin'' ("cold"), ''tchili'' ("snow"), or ''chilli'' ("where the land ends"). Chile is one of the Spanish-speaking countries where chilis are known as ''ají'', a word of [[Taíno]] origin.
There is some disagreement about whether it is proper to use the word "pepper" when discussing chili peppers because "pepper" originally referred to the genus [[Piper (genus)|Piper]], not Capsicum. Despite this dispute, a sense of ''pepper'' referring to Capsicum is supported by English dictionaries, including the [[Oxford English Dictionary]] (sense 2b of ''pepper'') and [[Merriam-Webster]] [http://www.m-w.com/cgi-bin/dictionary?book=Dictionary&va=pepper]. Furthermore, the word "pepper" is commonly used in the botanical and culinary fields in the names of different types of chili peppers.
==Nutritional value==
Red chilis are very rich in [[vitamin C]] and [[Carotene|provitamin A]]. Yellow and especially green chilis (which are essentially unripe fruit) contain a considerably lower amount of both substances. In addition, peppers are a good source of most [[B vitamins]], and [[vitamin B6]] in particular. They are very high in [[potassium]] and high in [[magnesium]] and [[iron]]. Their high vitamin C content can also substantially increase the uptake of non-heme iron from other ingredients in a meal, such as [[bean]]s and [[grain]]s. Recent studies reveal that chili peppers can have a wide range of benefits from helping alleviate pain in [[arthritis]] patients,<ref>[http://news.bbc.co.uk/1/hi/health/4993576.stm Could chilli peppers relieve pain?], [http://news.bbc.co.uk/1/hi/health/2281222.stm Chilli pepper link to arthritis pain] - [[BBC]]</ref> to acting effectively against [[cancer]] causing [[tumor]]s.<ref>[http://www.medicalnewstoday.com/healthnews.php?newsid=60504 Non-prescription Compound Found In Chillies Destroys Cancer Tumours Safely]</ref> Experts say capsaicin, the chemical that gives spicy food its kick, could be used to kill tumours with few or no side effects for the patient.<ref>[http://www.dailymail.co.uk/pages/live/articles/health/healthmain.html?in_article_id=427558&in_page_id=1774 Spicy foods 'could protect against cancer'] [[9 January]] [[2007]], [[Daily Mail]]</ref> Hot peppers, along with other [[spice]]s are also known for its ability to kill [[parasite]]s in the [[gastro-intestinal tract]]; for this reason, they are a useful dietary component in tropical regions.<ref>[http://www.discover.com/issues/sep-00/departments/featbiolog
