       Definition of terms commonly used in the Aloe industry




The part of the Aloe vera plant used in commerce, where processing is begun without stripping off the rind.

Whole leaf

Historically used to describe products derived from the entire leaf that were filtered/purified. However, use of this terminology without adequate additional descriptors is not recommended. This terminology is now seen on products or in reference to raw material where the entire leaf is used as a starting ingredient to create Aloe vera juice.

Decolorized whole leaf

A process, usually involving filtration with activated charcoal, that clarifies the liquid aloe mass.

Inner leaf

Plant part used to describe the clear, central parenchymatous tissues of the aloe leaf.

Aloe latex

Brown, yellow-brown, or occasionally red exudate found between the rind and inner leaf. Also called “sap,” it contains several constituents, but most notably anthraquinones.


An organic compound primarily found in the aloe latex, whose structure serves as the basic building block for several naturally occurring plant pigments. The substance is commonly used for laxative purposes.


Liquid product typically derived from the inner leaf.


Liquid product derived from Aloe vera leaf [the Working Group noted that the term “juice” is used arbitrarily and may either apply to products from the latex or from the gel].
