&lt;br /&gt;
The [[APG IV system]] (2016) places the genus in the family [[Asphodelaceae]], subfamily [[Asphodeloideae]]. Within the subfamily it may be placed in the tribe [[Aloeae]].&amp;lt;ref name=APweb&amp;gt;Stevens, P.F. (2001 onwards). &amp;quot;[http://www.mobot.org/MOBOT/research/APweb/orders/asparagalesweb.htm#aspasphodelaceae Asphodelaceae]&amp;quot;. &amp;#039;&amp;#039;Angiosperm Phylogeny Website&amp;#039;&amp;#039;. Retrieved 2016-06-09.&amp;lt;/ref&amp;gt; In the past, it has been assigned to the family [[Aloaceae]] (now included in the Asphodeloidae) or to a broadly [[Circumscription (taxonomy)|circumscribed]] family [[Liliaceae]] (the lily family). The plant &amp;#039;&amp;#039;[[Agave americana]]&amp;#039;&amp;#039;, which is sometimes called &amp;quot;American aloe&amp;quot;, belongs to the [[Asparagaceae]], a different family.&lt;br /&gt;
&lt;br /&gt;
The genus is native to tropical and southern [[Africa]], [[Madagascar]], [[Jordan]], the [[Arabian Peninsula]], [[India]] and various islands in the [[Indian Ocean]] ([[Mauritius]], [[Réunion]], [[Comoros]], etc.). A few species have also become naturalized in other regions ([[Mediterranean]], [[Australia]], [[North America|North]] and [[South America]], [[Hawaiian Islands]], etc.).&amp;lt;ref name=&amp;quot;POWO&amp;quot;&amp;gt;{{cite web |url=https://powo.science.kew.org/taxon/urn:lsid:ipni.org:names:30106039-2 |title=&amp;#039;&amp;#039;Aloe&amp;#039;&amp;#039; |date=2022 |work=Plants of the World Online |publisher=[[Royal Botanic Gardens, Kew]] |access-date=16 December 2022}}&amp;lt;/ref&amp;gt;&lt;br /&gt;

== Etymology ==&lt;br /&gt;
The genus name &amp;#039;&amp;#039;Aloe&amp;#039;&amp;#039; is derived from the [[Arabic]] word &amp;#039;&amp;#039;al&amp;#039;uluh&amp;#039;&amp;#039;, meaning &amp;quot;bitter and shiny substance&amp;quot; or from [[Hebrew language|Hebrew]] {{lang|he|אוהלים}} &amp;#039;&amp;#039;ahalim&amp;#039;&amp;#039;, plural of {{lang|he|אוהל}} &amp;#039;&amp;#039;ahal&amp;#039;&amp;#039;.&amp;lt;ref name=&amp;quot;oed&amp;quot;&amp;gt;{{cite web|url=https://www.etymonline.com/word/aloe |title=Aloe |last1=Harper |first1=Douglas |publisher=Online Etymology Dictionary |access-date=1 July 2021 |date=2021}}&amp;lt;/ref&amp;gt;&amp;lt;ref name=&amp;quot;guo&amp;quot;&amp;gt;{{cite journal |last1=Guo |first1=Xiaoqing |last2=Mei |first2=Nan |title=Aloe vera: A review of toxicity and adverse clinical effects |journal=J Environ Sci Health C Environ Carcinog Ecotoxicol Rev |date=2 April 2016 |volume=34 |issue=2 |pages=77–96 |doi=10.1080/10590501.2016.1166826 |pmid=26986231 |pmc=6349368 |bibcode=2016JESHC..34...77G }}&amp;lt;/ref&amp;gt;&amp;lt;ref&amp;gt;{{cite web |url=https://www.balashon.com/2008/03/aloe.html |title=aloe |last1=Curwin |first1=David |date=16 March 2008 |website=Balashon - Hebrew Language Detective |access-date=16 December 2022 }}&amp;lt;/ref&amp;gt;&lt;br /&gt;

== Description ==&lt;br /&gt;
&lt;br /&gt;
Most &amp;#039;&amp;#039;Aloe&amp;#039;&amp;#039; species have a [[rosette (botany)|rosette]] of large, thick, fleshy [[Leaf|leaves]]. &amp;#039;&amp;#039;Aloe&amp;#039;&amp;#039; [[flower]]s are tubular, frequently yellow, orange, pink, or red, and are borne, densely clustered and pendant, at the apex of simple or branched, leafless stems. Many species of &amp;#039;&amp;#039;Aloe&amp;#039;&amp;#039; appear to be stemless, with the rosette growing directly at ground level; other varieties may have a branched or unbranched [[plant stem|stem]] from which the fleshy leaves spring. They vary in color from grey to bright-green and are sometimes striped or [[mottle]]d. Some aloes native to South Africa are tree-like (arborescent).&amp;lt;ref name=RoddStackhouse&amp;gt;{{cite book|last=Rodd|first=Tony|title=Trees: a Visual Guide|year=2008|publisher=University of California Press|location=Berkeley|isbn=9780520256507|page=131|author2=Stackhouse, Jennifer}}&amp;lt;/ref&amp;gt;&lt;br /&gt;
&lt;br /&gt;
==Systematics==&lt;br /&gt;
&lt;br /&gt;
The [[APG IV system]] (2016) places the genus in the family [[Asphodelaceae]], subfamily [[Asphodeloideae]].&amp;lt;ref name=APweb/&amp;gt; In the past it has also been assigned to the families [[Liliaceae]] and Aloeaceae, as well as the family Asphodelaceae [[sensu stricto]], before this was merged into the Asphodelaceae [[sensu lato]].&lt;br /&gt;
&lt;br /&gt;
The [[circumscription (taxonomy)|circumscription]] of the genus has varied widely. Many genera, such as [[Lomatophyllum]],&amp;lt;ref name=&amp;quot;WCSP_280369&amp;quot;&amp;gt;{{cite web |title=&amp;#039;&amp;#039;Lomatophyllum&amp;#039;&amp;#039; |work=World Checklist of Selected Plant Families |publisher=[[Royal Botanic Gardens, Kew]] |url=http://apps.kew.org/wcsp/namedetail.do?name_id=280369 |access-date=2013-02-25}}&amp;lt;/ref&amp;gt; have been brought into [[synonym (taxonomy)|synonymy]]. Species at one time placed in &amp;#039;&amp;#039;Aloe&amp;#039;&amp;#039;, such as &amp;#039;&amp;#039;[[Agave americana]]&amp;#039;&amp;#039;, have been moved to other genera.&amp;lt;ref name=&amp;quot;WCSP_297041&amp;quot;&amp;gt;{{cite web |title=&amp;#039;&amp;#039;Aloe americana&amp;#039;&amp;#039; |work=World Checklist of Selected Plant Families |publisher=[[Royal Botanic Gardens, Kew]] |url=http://apps.kew.org/wcsp/namedetail.do?name_id=297041 |access-date=2013-02-25}}&amp;lt;/ref&amp;gt; [[Molecular phylogenetics|Molecular phylogenetic studies]], particularly from 2010 onwards, suggested that as then circumscribed, &amp;#039;&amp;#039;Aloe&amp;#039;&amp;#039; was not [[Monophyly|monophyletic]] and should be divided into more tightly defined genera. In 2014, [[John Charles Manning]] and coworkers produced a phylogeny in which &amp;#039;&amp;#039;Aloe&amp;#039;&amp;#039; was divided into six genera: &amp;#039;&amp;#039;[[Aloidendron]]&amp;#039;&amp;#039;, &amp;#039;&amp;#039;[[Kumara (plant)|Kumara]]&amp;#039;&amp;#039;, &amp;#039;&amp;#039;[[Aloiampelos]]&amp;#039;&amp;#039;, &amp;#039;&amp;#039;Aloe&amp;#039;&amp;#039;, &amp;#039;&amp;#039;[[Aristaloe]]&amp;#039;&amp;#039; and &amp;#039;&amp;#039;[[Gonialoe]]&amp;#039;&amp;#039;.&amp;lt;ref name=MannBoatDaruMaur14/&amp;gt;&lt;br /&gt;

In addition to the species and hybrids between species within the genus, several hybrids with other genera have been created in cultivation, such as between &amp;#039;&amp;#039;Aloe&amp;#039;&amp;#039; and &amp;#039;&amp;#039;[[Gasteria]]&amp;#039;&amp;#039; ([[× Gasteraloe|× &amp;#039;&amp;#039;Gasteraloe&amp;#039;&amp;#039;]]), and between &amp;#039;&amp;#039;Aloe&amp;#039;&amp;#039; and &amp;#039;&amp;#039;[[Astroloba]]&amp;#039;&amp;#039; (&amp;#039;&amp;#039;[[×Aloloba]]&amp;#039;&amp;#039;).&lt;br /&gt;

&lt;br /&gt;
==Uses==&lt;br /&gt;
Aloe species are frequently cultivated as ornamental plants both in gardens and in pots. Many aloe species are highly decorative and are valued by collectors of succulents. &amp;#039;&amp;#039;Aloe vera&amp;#039;&amp;#039; is used both internally and externally on humans as [[folk medicine|folk]] or [[alternative medicine|alternative]] medicine.&amp;lt;ref&amp;gt;{{Cite journal |last1=Woźniak |first1=Anna |last2=Paduch |first2=Roman |date=2012-02-01 |title=Aloe vera extract activity on human corneal cells |journal=Pharmaceutical Biology |volume=50 |issue=2 |pages=147–154 |doi=10.3109/13880209.2011.579980 |issn=1388-0209 |pmid=22338121|s2cid=40123094 |doi-access=free }}&amp;lt;/ref&amp;gt; The &amp;#039;&amp;#039;Aloe&amp;#039;&amp;#039; species is known for its medicinal and cosmetic properties.&amp;lt;ref name=&amp;quot;:0&amp;quot;&amp;gt;{{Cite journal|last1=Fentaw|first1=Eshetu|last2=Dagne|first2=Kifle|last3=Wondimu|first3=Tigist|last4=Demissew|first4=Sebsebe|last5=Bjorå|first5=Charlotte S.|last6=Grace|first6=Olwen M.|date=2020-11-11|title=Uses and perceived sustainability of Aloe L.

Numerous cultivars with mixed or uncertain parentage are grown.

===Historical uses===&lt;br /&gt;
[[File:Aloe, Juliana Anicia Codex.jpg|thumb|Depiction of Aloe, labeled in Greek &amp;quot;ΑΛΟΗ&amp;quot; (Aloë) from the [[Juliana Anicia Codex]], a copy, written in [[Constantinople]] in 515 AD, of [[Dioscorides]]&amp;#039; 1st century AD work.&amp;lt;ref name=&amp;quot;Folio 15 Juliana Anicia Codex&amp;quot;&amp;gt;Folio 15 [[Juliana Anicia Codex]]&amp;lt;/ref&amp;gt;]]&lt;br /&gt;
Historical use of various aloe species is well documented. Documentation of the clinical effectiveness is available, although relatively limited.&amp;lt;ref name=NIH/&amp;gt;&amp;lt;ref&amp;gt;{{cite book|title=Aloes: the Genus &amp;#039;&amp;#039;Aloe&amp;#039;&amp;#039; |year=2004 |publisher=CRC Press |location=Boca Raton |isbn=978-0-415-30672-0 |editor=Tom Reynolds}}&amp;lt;/ref&amp;gt;&lt;br /&gt;
&lt;br /&gt;
Of the 500+ species, only a few were used traditionally as [[herbal medicine]]s, &amp;#039;&amp;#039;Aloe vera&amp;#039;&amp;#039; again being the most commonly used species. Also included are &amp;#039;&amp;#039;A. perryi&amp;#039;&amp;#039; and &amp;#039;&amp;#039;A. ferox&amp;#039;&amp;#039;. The Ancient Greeks and Romans used &amp;#039;&amp;#039;Aloe vera&amp;#039;&amp;#039; to treat wounds. In the Middle Ages, the yellowish liquid found inside the leaves was favored as a [[purgative]].&amp;lt;ref name=&amp;quot;Folio 15 Juliana Anicia Codex&amp;quot;/&amp;gt; Unprocessed aloe that contains [[aloin]] is generally used as a laxative, whereas processed juice does not usually contain significant aloin.&amp;lt;ref name=AloeSideEffects&amp;gt;{{cite web|url=http://www.superfoodliving.com/aloe-vera-juice-how-to-make-it-and-its-side-effects|title=Aloe Vera Juice - How to Make it and its Side Effects|date=November 20, 2015}}&amp;lt;/ref&amp;gt;&lt;br /&gt;
&lt;br /&gt;
According to [[Cancer Research UK]], a potentially deadly product called T-UP is made of concentrated aloe, and promoted as a cancer cure. They say &amp;quot;there is currently no evidence that aloe products can help to prevent or treat cancer in humans&amp;quot;.&amp;lt;ref&amp;gt;{{cite web&lt;br /&gt;

&lt;br /&gt;
===Aloin in OTC laxative products===&lt;br /&gt;
On May 9, 2002, the US Food and Drug Administration issued a final rule banning the use of aloin, the yellow sap of the aloe plant, for use as a laxative ingredient in [[over-the-counter drug]] products.&amp;lt;ref name=&amp;quot;pmid12001972&amp;quot;&amp;gt;{{cite journal |title=Status of certain additional over-the-counter drug category II and III active ingredients. Final rule |journal=Fed Regist |volume=67 |issue=90 |pages=31125–7 |year=2002 |pmid=12001972 |publisher= Food and Drug Administration, HHS|last1=Food Drug Administration |first1=HHS }}&amp;lt;/ref&amp;gt; Most aloe juices today do not contain significant aloin.&lt;br /&gt;
&lt;br /&gt;
=== Chemical properties ===&lt;br /&gt;
According to W. A. Shenstone, two classes of aloins are recognized: (1) nataloins, which yield [[picric acid|picric]] and [[oxalic acid]]s with [[nitric acid]], and do not give a red coloration with nitric acid; and (2) [[barbaloin]]s, which yield aloetic acid (C&amp;lt;sub&amp;gt;7&amp;lt;/sub&amp;gt;H&amp;lt;sub&amp;gt;2&amp;lt;/sub&amp;gt;N&amp;lt;sub&amp;gt;3&amp;lt;/sub&amp;gt;O&amp;lt;sub&amp;gt;5&amp;lt;/sub&amp;gt;), chrysammic acid (C&amp;lt;sub&amp;gt;7&amp;lt;/sub&amp;gt;H&amp;lt;sub&amp;gt;2&amp;lt;/sub&amp;gt;N&amp;lt;sub&amp;gt;2&amp;lt;/sub&amp;gt;O&amp;lt;sub&amp;gt;6&amp;lt;/sub&amp;gt;), picric and oxalic acids with nitric acid, being reddened by the acid. This second group may be divided into a-barbaloins, obtained from Barbados &amp;#039;&amp;#039;Aloe&amp;#039;&amp;#039;, and reddened in the cold, and b-barbaloins, obtained from &amp;#039;&amp;#039;Aloe Socotrina&amp;#039;&amp;#039; and Zanzibar &amp;#039;&amp;#039;Aloe&amp;#039;&amp;#039;, reddened by ordinary nitric acid only when warmed or by fuming acid in the cold. Nataloin (2C&amp;lt;sub&amp;gt;17&amp;lt;/sub&amp;gt;H&amp;lt;sub&amp;gt;13&amp;lt;/sub&amp;gt;O&amp;lt;sub&amp;gt;7&amp;lt;/sub&amp;gt;·H&amp;lt;sub&amp;gt;2&amp;lt;/sub&amp;gt;O) forms bright-yellow scales, barbaloin (C&amp;lt;sub&amp;gt;17&amp;lt;/sub&amp;gt;H&amp;lt;sub&amp;gt;18&amp;lt;/sub&amp;gt;O&amp;lt;sub&amp;gt;7&amp;lt;/sub&amp;gt;) [[Prism (geometry)|prism]]atic crystals. &amp;#039;&amp;#039;Aloe&amp;#039;&amp;#039; species are used in essential oils as a safety measure to dilute the solution before they are applied to the skin.&amp;lt;ref&amp;gt;{{Cite journal|last1=Orchard|first1=Ané|last2=Kamatou|first2=Guy|last3=Viljoen|first3=Alvaro M.|last4=Patel|first4=Namita|last5=Mawela|first5=Patricia|last6=van Vuuren|first6=Sandy F.|date=2019-01-14|title=The Influence of Carrier Oils on the Antimicrobial Activity and Cytotoxicity of Essential Oils|journal=Evidence-Based Complementary and Alternative Medicine|volume=2019|pages=1–24|doi=10.1155/2019/6981305|issn=1741-427X|pmc=6348851|pmid=30733812|doi-access=free}}&amp;lt;/ref&amp;gt;&lt;br /&gt;
