The Science Behind Tree of Life:

d-Lenolate®, also known as olive leaf (Olea Europaea) extract, is a formulation developed through a patented extraction process of selected olive leaves that contain Oleuropein.

The health benefits of olive trees have been documented for centuries. Scientists determined the phytochemicals contained in the trees/leaves are the source of vast disease resisting properties, which enables olive trees to live for thousands of years. Medical experts have discovered the wonders of the phenolic compound extracted from the olive leaves called Oleuropein.

Oleuropein contains both anti-viral and anti-microbial properties and is the potent ingredient that enables Tree of Life’s defense against toxins and prevent future attacks on the body’s immune system. It is Rev222’s special extraction method that makes this remarkable component absorbable and able to proactively function in the human body. The health benefits derived from the olive leaf continue to be extolled by both herbalists and medical scientists.


Testing for Tree of Life:

Tree of Life has been evaluated for its effectiveness against infections caused by the influenza virus and demonstrated early protective abilities against infections. Reports produced by research scientists associated with well-known domestic and international universities, further indicated that Tree of Life and its effective components have a direct causal and documented effect on some of the worst diseases afflicting the world today such as HIV, E. coli, Herpes and others.
