== Etymology ==
The word ''[[wiktionary:liquorice|liquorice]]'' (UK, CAN), or ''[[wiktionary:licorice|licorice]]'' (US), is derived via the [[Anglo-Norman language|Anglo-French]] {{lang|xno|lycorys}}, from [[Late Latin]] {{lang|la|liquiritia}},<ref name="NED_liquorice">{{Cite encyclopedia|title=Liquorice, licorice|date=1908|encyclopedia=A [[New English Dictionary]] On Historical Principles (NED)|publisher=Clarendon Press|location=Oxford, England|url=https://archive.org/details/oed6aarch/page/n345/mode/1up|access-date=2021-04-07|volume=VI. L to N|page=332|editor-last=Bradley|editor-first=Henry|language=en}}</ref> itself ultimately derived from Greek {{langx|grc|γλυκύρριζα|glykyrrhiza|label=none}} (the [[Modern Greek]] spelling of the genus is {{langx|el|γλυκόριζα|glykoriza|label=none}})<ref name="KriarasDict_glukurriza">{{Cite web|url=https://www.greek-language.gr/greekLang/medieval_greek/kriaras/search.html?lq=%CE%B3%CE%BB%CF%85%CE%BA%CF%8D%CF%81%CF%81%CE%B9%CE%B6%CE%B1&dq=|title=γλυκύρριζα|access-date=2021-04-07|website=Epitome of the Kriaras Dictionary (online version)|publisher=[[Center for the Greek Language]]|at=Portal for the greek language|language=el}}</ref> literally meaning 'sweet root' and referring to ''Glycyrrhiza glabra''.<ref>{{LSJ|gluku/rriza|γλυκύρριζα|ref}}.</ref>

The latter gives the plant [[Binomial nomenclature|binomial name]] with ''glabra'' meaning ''smooth''<ref>{{L&S|glaber|glabra|ref}}</ref> and referring to the plant's smooth husks; the former came to being via the influence of {{lang|la|liquere}}, 'to become fluid', reflecting the method of extracting the sweet component from the roots.<ref>{{OEtymD|Licorice}}</ref>

{{as of|2021}}, its English common name is spelled 'liquorice' in most of the [[Commonwealth of Nations|Commonwealth]], but 'licorice' is also used in some countries.<ref name=nih/><ref name="MR_liquorice">{{Cite Merriam-Webster|Liquorice}}</ref><ref name="MR_licorice">{{Cite Merriam-Webster|Licorice}}</ref>

== Description ==
Liquorice is a [[herbaceous]] [[perennial]], growing to {{convert|1|m|in|-1}} in height, with [[pinnate]] [[leaf|leaves]] about {{cvt|7|–|15|cm|in|frac=2}} long, with 9–17 leaflets. The [[flower]]s are {{cvt|8-12|mm|in|frac=16}} long, purple to pale whitish blue, produced in a loose [[inflorescence]]. The [[fruit]] is an oblong [[legume|pod]], {{cvt|20-30|mm|in|frac=8}} long, containing several [[seed]]s.<ref name=rhs>Huxley, A., ed. (1992).

== Chemistry ==
[[File:Glycyrrhizic Acid.svg|thumb|left|Much of the sweetness in liquorice comes from [[glycyrrhizin]].]]

The scent of liquorice root comes from a complex and variable combination of compounds, of which [[anethole]] is some 3% of total volatiles.{{cn|date=June 2023}} Much of the [[sweetness]] in liquorice comes from glycyrrhizin, which has 30–50 times the sweetness of [[sugar]].{{cn|date=June 2023}} The sweetness is different from sugar, being less instant, tart, and lasting longer.

== Cultivation and uses ==
Liquorice grows best in well-drained soils in deep valleys with full sun. It is harvested in the autumn two to three years after planting.<ref name=rhs/>  Countries producing liquorice include Turkey, Greece, Iran, and Iraq.<ref name=drugs/>

===Tobacco===
Liquorice is used as a flavouring agent for [[tobacco]], for flavour-enhancing and moistening agents in the manufacture of American blend [[cigarette]]s, moist [[snuff (tobacco)|snuff]], [[chewing tobacco]], and [[pipe tobacco]].<ref name=nih/><ref name=drugs/><ref>Erik Assadourian, [http://www.worldwatch.org/brain/media/pdf/pubs/vs/2005_cigarettes.pdf Cigarette Production Drops] {{Webarchive|url=https://web.archive.org/web/20111209043353/http://www.worldwatch.org/brain/media/pdf/pubs/vs/2005_cigarettes.pdf |date=2011-12-09 }}, ''Vital Signs 2005'', at 70.</ref> Liquorice provides tobacco products with a natural sweetness and a distinctive flavour that blends readily with the natural and imitation flavouring components employed in the tobacco industry.<ref name=drugs/> Liquorice can also be added to cigarette [[rolling paper]]s. {{As of|2009}}, the US [[Food and Drug Administration]] banned the use of any "characterizing flavors" other than menthol from cigarettes, but not other manufactured tobacco products.<ref name="fda09">{{cite web|title=Flavored Tobacco|url=https://www.fda.gov/TobaccoProducts/Labeling/ProductsIngredientsComponents/ucm2019416.htm|archive-url=https://web.archive.org/web/20151028065518/http://www.fda.gov/TobaccoProducts/Labeling/ProductsIngredientsComponents/ucm2019416.htm|url-status=dead|archive-date=October 28, 2015|publisher=US Food and Drug Administration|access-date=21 December 2017|date=22 September 2009}}</ref>

===Food and confectionery===

[[File:Baton de reglisse.jpg|thumb|Dried sticks of liquorice root]]
Liquorice flavour is found in a wide variety of [[Liquorice (confectionery)|candies or sweets]]. In most of these candies, the taste is reinforced by [[aniseed]] oil so the actual content of liquorice is low.

In the Netherlands, liquorice confectionery (''drop'') is a common sweet sold in many forms. Mixing it with [[mentha|mint]], [[menthol]], [[aniseed]], or [[Bay Laurel|laurel]] is common. It is also mixed with [[ammonium chloride]] ({{lang|fi|salmiak}}); salmiak liquorice in the Netherlands is known as {{lang|nl|zoute drop}} ('[[salty liquorice]]'). Strong, [[salty liquorice|salty]] sweets are also consumed in [[Nordic countries]] where liquorice flavoured alcohols are sold, particularly in Denmark and Finland.{{cn|date=June 2023}}

Dried sticks of the liquorice root are a traditional confectionery in the Netherlands as were they once in Britain. They were sold simply as sticks of {{lang|nl|zoethout}} ('sweet wood') to chew on as a candy.

In Italy, Spain, and France, liquorice is used in its natural form. The root of the plant is simply harvested, washed, dried, and chewed as a mouth freshener. Throughout Italy, unsweetened liquorice is consumed in the form of small black pieces made only from 100% pure liquorice extract. In [[Calabria]], a [[liqueur]] is made from pure liquorice extract and in [[Reggio Emilia]] a [[soft drink]] called acqua d'orcio is made. In some parts of the [[Arab world]], including [[Egypt]] and the [[Levant]], the root of the liquorice plant is used to make a cold drink with a sweet and mildly bitter taste, called Erk al-sous. This beverage is especially popular during [[Ramadan]].<ref>[https://www.middleeasteye.net/discover/ramadan-five-drinks-thirst-quenching-middle-east Ramadan: Five thirst-quenching drinks from across the Middle East], Nur Ayoubi, 4 April 2022, [[Middle East Eye]]</ref>

In southeastern Turkey, such as in [[Diyarbakır]], liquorice root is traditionally made into a chilled beverage that is most commonly consumed in summer.<ref>{{cite web|url=https://mediterranean.observer/lemon-licorice-and-sumac-sherbet-drinks-to-beat-the-summer-heat/ |publisher=Mediterranean Observer |title=Lemon, Licorice and Sumac Sherbet: Drinks to beat the Summer Heat |date=22 August 2021 |archive-url=https://web.archive.org/web/20230329172000/https://mediterranean.observer/lemon-licorice-and-sumac-sherbet-drinks-to-beat-the-summer-heat/ |archive-date= 29 March 2023 |url-status=live}}</ref>

===Research===
{{See also|Glycyrrhizin|Enoxolone}}

Properties of glycyrrhizin are under preliminary research, such as for [[hepatitis C]] or [[topical]] treatment of [[psoriasis]], but the low quality of studies {{as of|2017|lc=y}} prevents conclusions about efficacy and safety.<ref name=nih/><ref name=drugs/><ref>{{cite journal|pmid=27786567|year=2017|last1=Yu|first1=J.

===Traditional medicine===
In [[traditional Chinese medicine]], a related species [[Glycyrrhiza uralensis|''G. uralensis'']] (often translated as "liquorice") is known as {{transliteration|zh|gancao}} ({{zh|c=甘草|l=sweet grass}}), and is believed to "harmonize" the ingredients in a formula.<ref>{{cite book |last=Bensky |first=Dan |title=Chinese Herbal Medicine: Materia Medica, Third Edition |publisher=Eastland Press |year=2004 |isbn=978-0-939616-42-8 |display-authors=etal}}</ref> although there is no high-quality [[clinical research]] to indicate it is safe or effective for any medicinal purpose.

==Adverse effects==
===Consumption levels===
The United States [[Food and Drug Administration]] regards that foods containing liquorice and its derivatives (including glycyrrhizin) are [[generally recognized as safe]] for use as a [[food ingredient]], if not consumed excessively.<ref name=nih/><ref name=drugs/><ref name=omar/> Other jurisdictions have suggested no more than {{convert|100|-|200|mg|abbr=in}} of glycyrrhizin per day, the equivalent of about {{convert|70|-|150|g|oz|frac=4|abbr=on}} of liquorice confectionery.<ref name=omar/> Although liquorice is considered safe as a food ingredient, glycyrrhizin can cause serious side effects if consumed in large amounts (above 0.2 mg per kg per day).<ref name=nih/><ref name=drugs/><ref name=omar/>  One estimate is that a normal healthy person can consume {{convert|10|mg|abbr=in}} of glycyrrhizic acid per day.<ref name="StørmerReistad1993">{{cite journal|last1=Størmer|first1=F.C.|last2=Reistad|first2=R.|last3=Alexander|first3=J.|title=Glycyrrhizic acid in liquorice—Evaluation of health hazard|journal=Food and Chemical Toxicology|volume=31|issue=4|year=1993|pages=303–312|issn=0278-6915|doi=10.1016/0278-6915(93)90080-I|pmid=8386690}}</ref>

Because the composition of liquorice extracts in various products may exist in a broad range, there is not enough scientific information to determine that a specific level of intake is safe or unsafe.<ref name=nih/><ref name=drugs/>

===Physiological effects===
The effects of excessive liquorice consumption on [[hypokalemia|lowering potassium levels in the blood]] and increasing [[blood pressure]] are a particular concern for people with hypertension (high blood pressure) or heart or kidney disease.<ref name=nih/>

Some adverse effects of liquorice consumed in amounts of 50 to 200 g per day over four weeks appear to be caused by [[glycyrrhizic acid]] (75 to 540 mg per day glycyrrhetinic acid) causing increases in blood pressure.<ref name=drugs/>

[[Apparent mineralocorticoid excess syndrome]] can occur when the body retains sodium, and loses potassium, altering biochemical and hormonal regulation.<ref name=omar/> Some of these activities may include raised [[aldosterone]] levels, decline of the [[renin–angiotensin system]] and increased levels of the [[atrial natriuretic hormone]] in order to compensate the variations in homoeostasis.<ref name=omar/><ref name="MackenzieHoefnagels1990">{{cite journal|last1=Mackenzie|first1=Marius A.|last2=Hoefnagels|first2=Willibrord H.

Other adverse effects may include [[electrolyte imbalance]], [[edema|oedema]], increased [[blood pressure]], weight gain, heart problems, and weakness. Symptoms depend on the severity of toxicity. Some other complaints include fatigue, [[shortness of breath]], [[kidney failure]], and paralysis.<ref name="BlachleyKnochel1980">{{cite journal|last1=Blachley|first1=Jon D.|last2=Knochel|first2=James P.|title=Tobacco Chewer's Hypokalemia: Licorice Revisited|journal=New England Journal of Medicine|volume=302|issue=14|year=1980|pages=784–785|issn=0028-4793|doi=10.1056/NEJM198004033021405|pmid=6986557}}</ref><ref name="Toner1985">{{cite journal| pmid= 4059165| last1= Toner | first1= J.

===Potential for toxicity===
The major dose-limiting toxicities of liquorice are [[corticosteroid]] in nature, because of the inhibitory effect that its chief active constituents, glycyrrhizin and [[enoxolone]], have on [[cortisol]] degradation, and include [[edema|oedema]], [[hypokalaemia]], weight gain or loss, and [[hypertension]].<ref name=drugs/><ref name="omar">{{cite journal |vauthors=Omar HR, Komarova I, El-Ghonemi M, Fathy A, Rashad R, Abdelmalak HD, Yerramadha MR, Ali Y, Helal E, Camporesi EM |title=Licorice abuse: time to send a warning message |journal=Therapeutic Advances in Endocrinology and Metabolism |volume=3 |issue=4 |pages=125–38 |date=August 2012 |pmid=23185686 |pmc=3498851 |doi=10.1177/2042018812454322}}</ref><ref>{{cite journal |last1=Olukoga |first1=A |first2=D |last2=Donaldson  |title=Liquorice and its health implications. |journal=The Journal of the Royal Society for the Promotion of Health |date=June 2000 |volume=120 |issue=2 |pages=83–9 |doi=10.1177/146642400012000203 |pmid=10944880|s2cid=39005138 }}</ref><ref>{{cite journal |last1=Armanini |first1=D |first2=C |last2=Fiore |first3=MJ |last3=Mattarello |first4=J |last4=Bielenberg |last5=Palermo |first5=M |title=History of the endocrine effects of licorice. |journal=Experimental and Clinical Endocrinology & Diabetes |date=September 2002 |volume=110 |issue=6 |pages=257–61 |doi=10.1055/s-2002-34587 |pmid=12373628}}</ref>

===Pregnancy===
Due to the possibility of [[Preterm birth|premature birth]] and health problems in children whose mothers consumed large amounts (about {{cvt|250|g}}) of liquorice extract per week, it is variously advised that during pregnancy "oral licorice extract in large amounts should be avoided",<ref name=nih/> liquorice "should be avoided"<ref name=drugs/> and "Liquorice is safe to eat. But you should avoid liquorice root."<ref>{{cite web|url=https://www.nhs.uk/pregnancy/keeping-well/foods-to-avoid/|title=Foods to avoid in pregnancy: other foods and drinks|date=19 May 2023|access-date=6 October 2025|publisher=UK National Health Service}}</ref>
