What is aloe vera? Aloe vera is a ‘succulent’, a plant adapted to dry and arid climates. Native to the hot dry climate of North Africa, this wonder plant has thick and spiny leaves filled with a clear gel. This gel is rich in amino acids, minerals, and vitamins, and has a long history of use, as far back as Ancient Egypt. Today it is still cultivated around the world for agricultural and therapeutic uses. Why is Healthspan’s better?
