Essiac Tea Studies

Essiac tea studies help us to learn more about how essiac works. Unfortunately, there are not a ton of studies that have been done, and most of those that have are on four herb essiac.

Rene Caisse and Dr. Charles Brusch performed many studies on the tea, but unfortunately that data is not readily available. To read more about what we do know, click here: Authentic Essiac: the story.

Because essiac is a plant, there is not a lot of financial incentive to study it. Because of that, most of the 'evidence' we have is simply in the form of personal stories. While we wish we had more, this is the reality. To read about these personal accounts, Click here.

Essiac Tea Studies

Free Radicals and Essiac Study.  Performed by: Pathology and Physiology Research Branch, Health Effects Laboratory Division, National Institute for Occupational Safety and Health, 1095 Willowdale Rd, MS/2015, Morgantown, WV 


***We use the entire sheep sorrel plant, including the roots, in our formula!***



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.
