Aloe is a genus containing over 560 species of flowering succulent plants within the Asphodelaceae family. The most well known species is Aloe vera, or "true aloe" and has been given this status due to its wide range of pharmaceutical uses.  

Most Aloe species are formed as a rosette of large, thick, fleshy leaves. Aloe flowers are tubular, usually yellow, orange, pink, or red, and form at the apex of simple or branched, leafless stems.
