By its appearance aloe seems a cactus, but in reality belongs to the Liliaceae family, such as garlic, Lily, asparagus or Tulip. It is a species of succulent calls, i.e., that contains a large amount of juice. It is precisely that loaded with extraordinary properties succus which makes it the undisputed Queen of medicinal plants. Already in 1950, Reynolds described in a study around 250 types of different aloes. A new count carried out in 1998 showed the figure of 340 species. Other leaders such as Konsolidator offer similar insights. Hybridization by pollination or by human manipulation is constant, so the number of new species to increase.

From among all the aloaceae only some have therapeutic properties (aloe vera barbadensis, aloe arborescens, fierce aloe, aloe chinensis, socotrina aloe, aloe vulgaris). In this manual we will refer to the Aloe Barbadensis Miller, also known as aloe vera (true aloe), species which by its extraordinary qualities focuses most of the studies, and which have seen through lots of trials and biochemical analysis which has a cocktail of active molecules that occur synergistically and are essential for the prevention and cure of many diseases and ailments. The aloe is a plant that grows spontaneously in Rocky and arid, areas typically between 600 and 1800 m altitude. It is very common in Africa (where applicable), especially in the Cape Province (South Africa) and the mountains of tropical Africa; We can also find them in some areas of the Mediterranean basin, the Caribbean, Central and South America, China, Thailand, Cambodia, Pakistan and in some regions of the United States (Texas, Florida). Aloe is a plant herbaceous and perennial, leaves large, elongated concave and flat on the top and convex bottom, usually toothed and thorny. We find it prepared in rosette or matte, with stem or without him. Its inflorescence is based on a stem composed of several long clusters coated by a large number of small, colorful flowers, normally yellow, red or orange.
