Aloe

Aloe (/ˈæloʊiː/ or /ˈæloʊ/), also written Aloë, is a genus containing over 500 species of flowering succulent plants. The most widely known species is Aloe vera, or "true aloe", so called because, though probably extinct in the wild, it is cultivated as the standard source of so-called "aloe vera" for assorted pharmaceutical purposes. Other species, such as Aloe ferox, also are cultivated or harvested from the wild for similar applications.
