The aloe vera (Aloe vera) plant has a long history of traditional therapeutic topical use. Its leaf and inner leaf juices are also ingested in various forms. Aloe vera leaf juice is made from macerated aloe leaves, and when it is intended for human ingestion, it is purified of latex constituents via a charcoal filtration process known as decolorization. Several publications have shown immunomodulatory effects, as well as antibacterial, antifungal and anti-parasitic properties of aloe vera inner leaf juice, but limited information is available regarding these effects for aloe vera leaf juice after the decolorization process. The aim of this preliminary study was to compare biologically-relevant antioxidant and immune-modulatory effects of aloe vera inner leaf and decolorized leaf preparations using a variety of in vitro techniques.
