By its appearance aloe seems a cactus, but actually belongs to the family of Liliaceae, 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. 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). Here 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 interact 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 the Caribbean, Central and South America, China, Thailand, Cambodia, Pakistan and in some regions of the United States (Texas, Florida). The aloe is a herbaceous perennial plant, of leaves large, elongated and succulent, concave and flat at the top, and convex on the lower, generally toothed and thorny. We find it prepared in rosette or matte, with stem or without him. Its inflorescence part of a stem composed of several long clusters coated by a large number of small, colorful flowers, normally yellow, red or orange.
