All About Aloe:
There are over 240 different species of Aloe, growing mainly in the dry regions of Africa, Asia, Europe and America.
Although Aloe vera is a member of the Lily family, it is very cactus-like in appearance.
Of the 240+ species of Aloe, four are recognized as having nutritional value, with Aloe barbadensis miller leading the group. Aloe barbadensis miller is the type of Aloe used in most commercial products with aloe content available today.
