In this study, the effects of Essiac on free radical scavenging and DNA damage, as well as the effects Essiac on lipid peroxidation was examined.

The data indicated that Essiac tea possesses potent antioxidant and DNA-protective activity, properties that are common to natural anti-cancer agents.

This study may help to explain the mechanisms behind the reported anti-cancer effects of Essiac.

Essiac and Prostate Cancer Study Performed by: Department of Biology, Indiana University-Purdue University Fort Wayne, Fort Wayne, IN, USA.

In this study, the ability of Essiac tea to modulate cancer cell proliferation and immune responsiveness was tested.

This study found that essiac preparations may be able to inhibit tumor cell growth while enhancing immune response to antigenic stimulation. This may be especially valuable in immune-suppressed individuals.
