"Stevia" is a genus of about 240 species of herbs and shrubs in the sunflower family (Asteraceae), native to subtropical and tropical South America and Central America. The species "Stevia rebaudiana" Bertoni, commonly known as sweetleaf, sweet leaf, sugarleaf, or simply stevia, is widely grown for its sweet leaves. As a sugar substitute, stevia's taste has a slower onset and longer duration than that of sugar, although some of its extracts may have a bitter or licorice-like aftertaste at high concentrations.

With its extracts having up to 300 times the sweetness of sugar, stevia has garnered attention with the rise in demand for low-carbohydrate, low-sugar food alternatives. Stevia also has shown promise in medical research for treating such conditions as obesity [ [http://www.ncbi.nlm.nih.gov/entrez/query.fcgi?db=PubMed&cmd=Search&term=stevia%20obese PubMed research articles related to treatments of obesity] ] and high blood pressure.

] However, health and political controversies have limited stevia's availability in many countries; for example, the United States banned it in the early 1990s unless labeled as a supplement. Stevia is widely used as a sweetener in Japan, and it is now available in the US and Canada as a dietary supplement, although not as a food additive. Rebiana is the trade name for a stevia-derived sweetener being developed jointly by The Coca-Cola Company and Cargill with the intent of marketing in several countries and gaining regulatory approval in the US and EU. Truvia is Cargill's consumer brand of Rebiana-based sweetener.

History and use

The genus "Stevia" consists of 240cite web | url = http://www.efloras.org/florataxon.aspx?flora_id=1&taxon_id=131515 | title = Stevia | work = Flora of North America] species of plants native to South America, Central America, and Mexico, with several species found as far north as Arizona, New Mexico, and Texas.cite web | url = http://plants.usda.gov/java/profile?symbol=STEVI | title = Stevia Cav. | work = USDA PLANTS ] Human use of the sweet species originated in South America. For centuries, the Guaraní tribes of Paraguay and Brazil used "Stevia" species, primarily "S. rebaudiana" which they called ka'a he'ê ("sweet herb"), as a sweetener in yerba mate and medicinal teas for treating heartburn and other ailments. The leaves of the stevia plant have 30–45 times the sweetness of sucrose (ordinary table sugar).

The exact structure of the aglycone and the glycoside were published in 1955.

In the early 1970s, Japan began cultivating stevia as an alternative to artificial sweeteners such as cyclamate and saccharin, which are suspected carcinogens. The plant's leaves, the aqueous extract of the leaves, and purified steviosides are used as sweeteners. Since the Japanese firm Morita Kagaku Kogyo Co., Ltd. produced the first commercial stevia sweetener in Japan in 1971, [cite web

Today, stevia is cultivated and used in food elsewhere in east Asia, including in China (since 1984), Korea, Taiwan, Thailand, and Malaysia. It can also be found in Saint Kitts and Nevis, in parts of South America (Brazil, Colombia, Peru, Paraguay, and Uruguay) and in Israel. China is the world's largest exporter of stevioside.

Stevia species are found in the wild in semi-arid habitats ranging from grassland to mountain terrain. Stevia does produce seeds, but only a small percentage of them germinate. Planting cloned stevia is a more effective method of reproduction.

Availability

Stevia has been grown on an experimental basis in Ontario, Canada since 1987 for the purpose of determining the feasibility of growing the crop commercially. In the United States, it is legal to import, grow, sell, and consume stevia products if contained within or labeled for use as a dietary supplement, but not as a food additive. Stevia has also been approved as a dietary supplement in Australia, New Zealandcite journal

Rebiana is the trade name for a patent-pending, calorie-free, food and beverage sweetener derived from stevia and developed jointly by The Coca-Cola Company and Cargill. In May 2007, Coca-Cola announced plans to obtain approval for its use as a food additive within the United States by 2009. Coca-Cola has also announced plans to market rebiana-sweetened products in 12 countries that allow stevia's use as a food additive. The two companies are conducting their own studies in an effort to gain regulatory approval in the United States and the European Union.

The U.S. ingredient firm Blue California claims to have developed an economical industrial production process for isolating Rebaudioside A, a sweet compound derived from stevia, using a "more economical and proprietary process". The company expects to go into industrial scale production in 2008. The isolation process for Rebaudioside A results in a product that delivers the desired sweetness without a bitter aftertaste.

Controversies

Health controversy

A 1985 study reported that steviol, a breakdown product from stevioside and rebaudioside (two of the sweet steviol glycosides in the stevia leaf), is a mutagen in the presence of a liver extract of pre-treated rats [cite journal

In 2006, the World Health Organization (WHO) performed a thorough evaluation of recent experimental studies of stevioside and steviols conducted on animals and humans, and concluded that "stevioside and rebaudioside A are not genotoxic "in vitro" or "in vivo" and that the genotoxicity of steviol and some of its oxidative derivatives "in vitro" is not expressed "in vivo"."cite journal

Political controversy

In 1991, at the request of an anonymous complaint, the United States Food and Drug Administration (FDA) labeled stevia as an "unsafe food additive" and restricted its import. The FDA's stated reason was "toxicological information on stevia is inadequate to demonstrate its safety." [Food and Drug Administration (1995, rev 1996, 2005). [http://www.fda.gov/ora/fiars/ora_import_ia4506.html Import Alert #45-06] : "Automatic Detention of Stevia Leaves, Extract of Stevia Leaves, and Food Containing Stevia"] This ruling was controversial, as stevia proponents pointed out that this designation violated the FDA's own guidelines under which any natural substance used prior to 1958 with no reported adverse effects should be generally recognized as safe (GRAS).

Stevia occurs naturally, requiring no patent to produce it. As a consequence, since the import ban in 1991, marketers and consumers of stevia have shared a belief that the FDA acted in response to industry pressure. Arizona congressman Jon Kyl, for example, called the FDA action against stevia "a restraint of trade to benefit the artificial sweetener industry." [Kyl, John (R-Arizona) (1993). Letter to former FDA Commissioner David Aaron Kessler about the 1991 stevia import ban, quoted at [http://www.herbalremedies.com/stevquotandc.html herbalremedies.com] .] Citing privacy issues, the FDA has not revealed the source of the original complaint in its responses to requests filed under the Freedom of Information Act.

The FDA requires proof of safety before recognizing a food additive as safe. A similar burden of proof is required for the FDA to ban a substance or label it "unsafe". Nevertheless, stevia remained banned until after the 1994 Dietary Supplement Health and Education Act forced the FDA in 1995 to revise its stance to permit stevia to be used as a dietary supplement, although not as a food additive — a position that stevia proponents regard as contradictory because it simultaneously labels stevia as safe and unsafe, depending on how it is sold.

Although unresolved questions remain concerning whether metabolic processes can produce a mutagen from stevia in animals, let alone in humans, the early studies nevertheless prompted the European Commission to ban stevia's use in food in the European Union pending further research. Singapore and Hong Kong have banned it also. However, more recent data compiled in the safety evaluation released by the World Health Organization in 2006 suggest that these policies may be obsolete.

Names in other countries

Both the sweetener and the stevia plant "Stevia rebaudiana" Bertoni (also known as "Eupatorium rebaudianum" Bertoni [cite web | url=http://www.ipni.org/ipni/idPlantNameSearch.do?id=100800-2&back_page=%2Fipni%2FeditSimplePlantNameSearch.do%3Ffind_wholeName%3DEupatorium%2Brebaudianum%26output_format%3Dnormal | title=Asteraceae "Eupatorium rebaudianum" Bertoni | work=International Plant Names Index] ) are known simply as "stevia" (pronEng|ˈstɛviə) in English-speaking countries as well as in France, Germany, Italy, Portugal, Israel, Norway and Sweden — although some of these countries also use other terms as shown below. Similar pronunciations occur in Japan ("sutebia" or ステビア in "katakana)", and in Thailand ("satiwia"). In some countries (India, for example) the name translates literally as "sweet leaf."
