By itself, aloe oil is not a true, pure oil. It is prepared by mixing the aloe vera plant with a fatty oil.1 This plant oil basically contains the properties of aloe, from which it is extracted. However, since it is combined with a carrier oil, its nutritional properties may be enhanced or reduced.
Most of the health benefits provided by aloe vera come from its water-retaining, fleshy leaves — specifically the nutrient-rich gel extracted from them. It is usually the leaves or gel that is used to create the oil. Aloe vera is a perennial plant and thrives in hot, arid environments. More specifically, it is commonly found in North Africa, the Canary Islands, the Mediterranean region, Australia, and some areas in the United States. Historical records show that aloe vera was an important component in herbal medicine. For instance, the Ebers Papyrus from Ancient Egypt and "De Materia Medica" by Dioscorides mention the use of aloe vera.
