But recent research shows this ancient remedy does much more. It is a powerful detoxifier, antiseptic and tonic for the nervous system. It also has immune-boosting and anti-viral properties.

Exactly what the ' active ingredient' is remains a bit of a mystery, however. Aloe vera is rich in mucopolysaccharides, one of which is called acemannan, but also contains enzymes, vitamins, minerals, essential fats and amino acids. Note that concentration can vary greatly from one product to another.
