Yerba mate (from Spanish ['?e??a 'mate]; Portuguese: erva-mate ['??v? 'mate] or ['??v? 'mat??]; Guarani: ka'a, IPA: [ka?a] ) is a species of the holly family (Aquifoliaceae), with the botanical name Ilex paraguariensis A. St.-Hil. named by the French botanist Auguste François César Prouvençal de Saint-Hilaire.
Yerba mate is widely known as the source of the beverage called mate in both Spanish and Portuguese, also called various other names in Portuguese like chimarrão, and tererê/tereré. It is traditionally consumed in central and southern regions of South America, primarily in Paraguay, as well as in Argentina, Uruguay, southern and central-western Brazil, the Chaco region of Bolivia and southern Chile. It is also very popular among the Druze community in Syria and Lebanon, where it is imported from Argentina. Yerba mate was initially utilized and cultivated by the Guaraní people and in some Tupí communities in southern Brazil, prior to European colonization. Yerba mate can also be found in various energy drinks on the market today.
Yerba mate translates to "mate herb", where mate is originally from the Quechua mati, a word that means "container for a drink", "infusion of an herb", as well as "gourd". In English, "mate" is occasionally written "maté", to distinguish it from other meanings of the word mate, although this spelling is not used in Spanish nor Portuguese. Moreover, with the accent the word maté in Spanish means "I killed", as pointed out by the Yerba Mate Association of the Americas.

Description
Yerba mate, or Ilex paraguariensis, begins as a shrub and then matures to a tree and can grow up to 15 metres (49 ft) tall. The leaves are evergreen, 7-110 millimetres (0.3-4.3 in) long and 30-55 millimetres (1.2-2.2 in) wide, with a serrated margin. The leaves are often called yerba (Spanish) or erva (Portuguese), both of which mean "herb". They contain caffeine (known in some parts of the world as mateine) and also contains related xanthine alkaloids and are harvested commercially.
The flowers are small, greenish-white, with four petals. The fruit is a red drupe 4-6 millimetres (0.16-0.24 in) in diameter.

Cultivation
The yerba mate plant is grown and processed in South America, specifically in northern Argentina (Corrientes, Misiones), Paraguay, Uruguay and southern Brazil (Rio Grande do Sul, Santa Catarina, Paraná and Mato Grosso do Sul). Cultivators are known as yerbateros (Spanish) or ervateiros (Brazilian Portuguese).
Seeds used to germinate new plants are harvested from January until April only after they have turned dark purple. After harvest, they are submerged in water in order to eliminate floating non-viable seeds and detritus like twigs, leaves, etc. New plants are started between March and May. For plants established in pots, transplanting takes place April through September. Plants with bare roots are transplanted only during the months of June and July.
Many of the natural enemies of yerba mate are difficult to control in a plantation setting. Insect pests include Gyropsylla spegazziniana, an insect that lays eggs in branches, Hedyphates betulinus, an insect that weakens the tree and makes it more susceptible to mold and mildew, Perigonia lusca, an insect that eats the leaves, and several species of mites.
When yerba mate is harvested, the branches are often dried by a wood fire, imparting a smoky flavor. The plant Ilex paraguariensis can vary in strength of the flavor, caffeine levels and other nutrients depending on whether it is a male or female plant. Female plants tend to be milder in flavor and lower in caffeine. They are also relatively scarce in the areas where yerba mate is planted and cultivated.
According to FAO in 2012, Brazil is the biggest producer of mate in the world with 513,256 MT (58%), followed by Argentina with 290,000 MT (32%) and Paraguay with 85,490 MT (10%).
Use as a beverage
The infusion, called mate in Spanish-speaking countries or chimarrão in Brazil, is prepared by filling a container, typically a gourd, up to three-quarters full with dry leaves (and twigs) of the mate plant, and filling it up with water at a temperature of 70-80 °C (158-176 °F), hot but not boiling. Sugar may or may not be added; and the mate may be prepared with cold water (tereré).
Drinking mate with friends from a hollow gourd (also called a guampa, porongo or mate in Spanish, cabaça or cuia in Portuguese, or zucca in Italian) through a metal straw (a bombilla in Spanish, bomba in Portuguese), refilling and passing to the next person after finishing the few mouthfuls of beverage, is a common social practice in Paraguay, Uruguay, Argentina and southern Brazil among people of all ages.
Although traditionally made from a hollowed calabash gourd, these days mate gourds are produced from a variety of materials including wood, glass, ceramic and more recently silicone.
Yerba mate is most popular in Paraguay and Uruguay, where people are seen walking the streets carrying the mate and termo (thermal vacuum flask) in their arms. You can also find hot water stations to refill the termo while on the road in Uruguay. In Argentina 5 kg (11 lb) of yerba mate is consumed annually per capita; in Uruguay, the largest consumer, consumption is 10 kg (22 lb). The amount of the herb used to prepare the infusion is much greater than that used for tea and other beverages, accounting for the large weight used.
The flavor of brewed mate resembles an infusion of vegetables, herbs, grass and is reminiscent of some varieties of green tea. Some consider the flavor to be very agreeable, but it is generally bitter if steeped in boiling water. Flavored mate is also sold, in which the mate leaves are blended with other herbs (such as peppermint) or citrus rind.
In Paraguay, Brazil and Argentina, a toasted version of mate, known as mate cocido (Paraguay), chá mate (Brazil) or just mate or "cocido" in Paraguay, is sold in teabags and in a loose leaf form. It is often served sweetened in specialized shops or on the street, either hot or iced, pure or with fruit juice (especially lime - known in Brazil as limão) or milk. In Paraguay, Argentina and southern Brazil, this is commonly consumed for breakfast or in a café for afternoon tea, often with a selection of sweet pastries (facturas).
An iced, sweetened version of toasted mate is sold as an uncarbonated soft drink, with or without fruit flavoring. In Brazil, this cold version of chá mate is especially popular in the South and Southeast regions, and can easily be found in retail stores in the same cooler as soft-drinks. Mate batido, which is toasted, has less of a bitter flavor and more of a spicy fragrance. Mate batido becomes creamy when shaken. Mate batido is more popular in the coastal cities of Brazil, as opposed to the far southern states, where it is consumed in the traditional way (green, consumed with a silver straw from a shared gourd), and called chimarrão (cimarrón in Spanish, particularly that of Argentina).
In Paraguay, western Brazil (Mato Grosso do Sul, west of São Paulo) and the Argentine littoral, a mate infusion, called tereré in Spanish and Portuguese or tererê in Portuguese in southern regions of Brazil, is also consumed as a cold or iced beverage, usually sucked out of a horn cup called guampa with a bombilla. Tereré can be prepared with cold water (the most common way in Paraguay and Brazil), or fruit juice (the most common way in Argentina). The version with water is more bitter; fruit juice acts as a sweetener (in Brazil, that is usually avoided with the addition of table sugar). Medicinal or culinary herbs, known as yuyos (weeds), may be crushed with a pestle and mortar, and added to the water for taste or medicinal reasons. Tereré is most popular in Paraguay, Brazil, and the Litoral (northeast Argentina).
In the same way as people meet for tea or coffee, friends often gather and drink mate (matear) in Paraguay, Argentina, southern Brazil, and Uruguay. Sharing mate is almost a ritual, following customary rules. In warm weather the hot water is sometimes replaced by lemonade, but not in Uruguay. Paraguay typically drinks yerba mate with cold water during hot days and hot water in the morning and cooler temperatures.
The gourd (mate in Spanish) is given by the brewer to each person, often in a circle, in turn; the recipient gives thanks, drinks the few mouthfuls and returns the mate to the brewer, who refills it and passes it to the next person in clockwise order.
Paraguayans have a tradition of mixing mate with crushed leaves, stems, and flowers of the plant known as flor de agosto (the flower of August, plants of the Senecio genus, particularly Senecio grisebachii), which contain pyrrolizidine alkaloids. Modifying mate in this fashion is potentially toxic, as these alkaloids can cause a rare condition of the liver, veno-occlusive disease, which produces liver failure due to progressive occlusion of the small venous channels in the liver.
In South Africa, mate is not well known, but has been introduced to Stellenbosch by a student who sells it nationally. In the tiny hamlet of Groot Marico in the northwest province, mate was introduced to the local tourism office by the returning descendants of the Boers, who in 1902 had emigrated to Patagonia in Argentina after losing the Anglo Boer War. It is also commonly consumed in Lebanon, Syria and some other parts of the Middle East mainly by Druze and Alawite population, following emigration to South America and return by many people, and worldwide by expatriates from the Southern Cone.
Chemical composition and properties
Polyphenols
Yerba mate contains a variety of polyphenols such as the flavonoids quercetin and rutin.
Xanthines
Yerba mate contains three xanthines: caffeine, theobromine and theophylline, the main one being caffeine. Caffeine content varies between 0.7% and 1.7% of dry weight (compared with 0.4-9.3% for tea leaves, 2.5-7.6% in guarana, and up to 3.2% for ground coffee); theobromine content varies from 0.3% to 0.9%; theophylline is present in small quantities, or can be completely absent. A substance previously called "mateine" is a synonym for caffeine (like theine and guaranine).
Mineral content
Yerba mate also contains elements such as potassium, magnesium, and manganese.
Health effects
Yerba mate has been claimed to have various effects on human health and these effects have been attributed to the high quantity of polyphenols found in mate tea. Research has found that yerba mate may improve allergy symptoms and reduce the risk of diabetes mellitus and high blood sugar in mice.
Mate also contains compounds that act as an appetite suppressant and possible weight loss tool, increases mental energy and focus, improves mood, and promotes deeper sleep; however, sleep may only be affected in people who are sensitive to caffeine.
Before 2011, there were no double-blind, randomized prospective clinical trials of yerba mate consumption with respect to chronic disease. However, many studies have been conducted since then, pointing to at least some probable benefits from some claims, such as reduction of fat cells, inflammation and cholesterol, although more research is needed. Some non-blinded studies have found mate consumption to be effective in lipid lowering. Another study determined that mate reduces progression of artheriosclerosis in rabbits but did not decrease serum cholesterol or aortic TBARS and antioxidant enzymes.
Cancer
The consumption of hot mate tea is associated with oral cancer, esophageal cancer, cancer of the larynx, and squamous cell cancers of the head and neck. Studies show a correlation between tea temperature and likelihood of cancer, making it unclear how much of a role mate itself plays as a carcinogen.
Weight loss
Yerba mate contains polyphenols such as flavonoids and phenolic acids, which work by inhibiting enzymes like pancreatic lipase and lipoprotein lipase, which in turn play a role in fat metabolism. Yerba mate has been shown to increase satiety by slowing gastric emptying. Effects on weight loss may be due to reduced absorption of dietary fats and/or altered cholesterol metabolism.
Despite yerba mate's potential for reducing body weight, there is minimal data on the effects of yerba mate on body weight in humans. Therefore, yerba mate should not be recommended over diet and physical exercise without further study on its effects.
Mechanism of action
E-NTPDase activity
Research also shows that mate preparations can alter the concentration of members of the ecto-nucleoside triphosphate diphosphohydrolase (E-NTPDase) family, resulting in an elevated level of extracellular ATP, ADP, and AMP. This was found with chronic ingestion (15 days) of an aqueous mate extract, and may lead to a novel mechanism for manipulation of vascular regenerative factors, i.e., treating heart disease.
Antioxidants
In an investigation of mate antioxidant activity, there was a correlation found between content of caffeoyl-derivatives and antioxidant capacity (AOC). Amongst a group of Ilex species, Ilex paraguariensis antioxidant activity was the highest.
Monoamine oxidase inhibition activity
A paper from the University of São Paulo cites yerba mate extract as an inhibitor of MAO activity; the maximal inhibition observed in vitro was 40-50%. A monoamine oxidase inhibitor is a type of antidepressant, so there is some data to suggest that yerba mate has a calming effect in this regard.
History
Mate was first consumed by the indigenous Guaraní and also spread in the Tupí people that lived in southern Brazil, Paraguay and became widespread during European colonization. In the Spanish colony of Paraguay in the late 16th century, both Spanish settlers and indigenous Guaranís, who had, to some extent, before the Spanish arrival, consumed it. Mate consumption spread in the 17th century to the River Plate and from there to Argentina, Chile, Bolivia and Peru. This widespread consumption turned it into Paraguay's main commodity above other wares, such as tobacco, and indigenous peoples labour was used to harvest wild stands.
In the mid 17th century, Jesuits managed to domesticate the plant and establish plantations in their Indian reductions in Misiones, Argentina, sparking severe competition with the Paraguayan harvesters of wild stands. After their expulsion in the 1770s, their plantations fell into decay, as did their domestication secrets. The industry continued to be of prime importance for the Paraguayan economy after independence, but development in benefit of the Paraguayan state halted after the War of the Triple Alliance (1864-1870) that devastated the country both economically and demographically. Some regions with mate plantations in Paraguay became Argentine territory.
Brazil then became the largest producer of mate. In Brazilian and Argentine projects in the late 19th and early 20th centuries, the plant was domesticated once again, opening the way for plantation systems. When Brazilian entrepreneurs turned their attention to coffee in the 1930s, Argentina, which had long been the prime consumer, took over as the largest producer, resurrecting the economy in Misiones Province, where the Jesuits had once had most of their plantations. For years, the status of largest producer shifted between Brazil and Argentina.
Now, Brazil is the largest producer, with 53%, followed by Argentina, 37% and Paraguay, 10%.
In the city of Campo Largo, state of Paraná, Brazil, there is a Mate Historic Park (Portuguese: Parque Histórico do Mate), funded by that state's government, to educate people on the sustainable harvesting methods needed to maintain the integrity and vitality of the oldest wild forests of mate in the world. As of June 2014, however, the park is closed to public visitation.
Nomenclature
The name given to the plant in Guaraní, language of the indigenous people who first cultivated and enjoyed mate, is ka'a, which has the same meaning as "herb". Congonha, in Portuguese, is derived from the Tupi expression, meaning something like "what keeps us alive", but a term rarely used nowadays. Mate is from the Quechua mati, a word that means container for a drink, infusion of an herb, as well as gourd. The word mate is used in both modern Portuguese and Spanish languages.
The pronunciation of yerba mate in Spanish is ['?e??a 'mate]. The accent on the word mate is on the first syllable, not the second. The word hierba is Spanish for "herb", where the initial "h" is silent. Yerba is a variant spelling of hierba used throughout Latin America, which was quite common in Argentina. Yerba may be understood as "herb", but also as "grass", or "weed". Nowadays in Argentina yerba refers exclusively to the yerba mate plant. Yerba mate, therefore, originally translated literally as the "gourd herb", i.e. the herb one drinks from a gourd.
The (Brazilian) Portuguese name for the plant is either erva-mate ['??v? 'mät?i], pronounced variously as ['??v? 'mäte], ['??v? 'mät?] or ['??v? 'mät??] in the regions of traditional consumption, ['æ???v? 'mä?t?] in coastal, urban Rio de Janeiro, the most used term, or rarely congonha [kõ'?õ???], from Old Tupi kõ'gõi, which means "what sustains the being". The drinks it is used to prepare are chimarrão (hot), tereré (cold) or chá mate (hot or cold). While the chá mate (tea) is made with the toasted leaves, the other drinks are made with green leaves, and are very popular in the south and center-west of the country. Most people colloquially address both the plant and the beverage simply by the word mate.
Both the spellings "mate" and "maté" are used in English to refer to the plant, but the latter spelling is never used in either Spanish or Portuguese for this meaning. In Spanish, maté is understood as being a conjugation of the verb matar (to kill), and it means "I killed". The corresponding Portuguese conjugation of matar (to kill) would be matei (I killed). There are no variations in spelling of mate (the plant) in Spanish. The addition of the acute accent over the final "e" in the English spelling was likely added as a hypercorrection, indicating that the final "-é" is not silent, and thus the word is distinct from the existing English word "mate" (friend, buddy). The MATE Desktop Environment for Linux operating systems named their project after the yerba mate plant, although in their website they used the spelling yerba maté.
In both Spanish and Portuguese the first syllable of mate (plant) is the tonic one, and thus according to their spelling rules, the word does not require a written accent. If the tonic syllable were the last one, the accent would be required, as maté. In Portuguese the pronunciation of a final accented vowel would be different to their unaccented counterparts, é being more open /?/, like ó /?/ and á /a/, and ê being more closed /e/, like ô /o/ and â /?/. The usual pronunciation of the mate vowel is [i ~ ? ~ e], never [?]. The standard in all regions where the Portuguese language is official is for unstressed vowels, particularly final ones, to be reduced, in the case of e through [i] in Brazil, here strongly palatalizing, and most of Africa, and [?], or occasionally non-palatalizing [i], in Portugal, Cape Verde and Macau, among a few others.
Use as a health food
Mate is consumed as a health food. Packages of yerba mate are available in health food stores and are frequently stocked in the large supermarkets of Europe, Australia and the United States. By 2013, Asian interest in the drink had seen significant growth and led to significant export trade.
