The Aloe family consists of flowering succulent plants that include about three hundred different varieties. The name Aloe probably comes from the Arabian word ‘alloeh’ which means ‘bitter substance’. These plants are stiff and rough, and mainly consist of a rosette of large, thick, fleshy leaves. The leaves are generally quite sharp with thorny edges. These plants can be of very different sizes. Its natural habitat region is limited to Africa: from South Africa to tropical Africa, and neighbouring regions such as Madagascar, the Arabian peninsula and several African Islands.
