Aloe vera is a succulent plant species of the genus Aloe. It is widely distributed, and is considered an invasive species in many world regions. An evergreen perennial, it originates from the Arabian Peninsula, but also grows wild in tropical, semi-tropical, and arid climates around the world.[4] It is cultivated for commercial products, mainly as a topical treatment used over centuries.[4][5] The species is considered attractive for decorative purposes, and is often used indoors as a potted plant.[

The leaves of Aloe vera contain significant amounts of the polysaccharide gel acemannan, which can be used for topical purposes.[7] The leaves also contain aloin, which is a toxic compound. Aloe vera products are typically made from the gel. Aloe vera acemannan may be used in skin lotions, cosmetics, ointments and gels for minor burns, skin abrasions, insect bites, and windburn.

Oral ingestion of aloe vera extracts may cause acute abdominal pain and cramps, and hepatitis if consumed chronically.[5][9] It should not be used during pregnancy. Some people have allergic reactions to aloe when used on skin.

Aloe vera has been widely grown as an ornamental plant. The species is popular with modern gardeners as a topical medicinal plant and for its interesting flowers, form, and succulence. This succulence enables the species to survive in areas of low natural rainfall, making it ideal for rockeries and other low water-use gardens. The species is hardy in zones 8–11, and is intolerant of heavy frost and snow. The species is relatively resistant to most insect pests, though spider mites, mealy bugs, scale insects, and aphid species may cause a decline in plant health.

Aloe vera is considered to be native to the south-east[31] Arabian Peninsula in the Hajar Mountains in north-eastern Oman and eastern U.A.E.[32] However, it has been widely cultivated around the world, and has become naturalized in North Africa, as well as Sudan and neighboring countries, along with the Canary Islands, Cape Verde, and Madeira Islands.[16] It has also naturalized in the Algarve region of Portugal,[33][34] and in wild areas across Spain, especially in the region of Murcia.
