The inclusion of sheep sorrel roots in Essiac has been well-documented and can be verified by clicking on the "Sheep Sorrel Roots" button above.

However, it is very possible that goldthread was also a part of the original 8-herb native herbalist tea in the late 1800s.  According to researchers Sheila Snow and Mali Klein, it appears that Rene Caisse did obtain goldthread from a man who wildcrafted it.

Goldthread contains a yellow substance called berberine which has anti-cancer properties as well as other health benefits.

"Berberine (BBR) has been extensively studied in vivo and vitro experiments.  BBR inhibits cell proliferation by regulating cell cycle and cell autophagy, and promoting cell apoptosis.

"BBR also inhibits cell invasion and metastasis by suppressing EMT and down-regulating the expression of metastasis-related proteins and signaling pathways.

"In addition, BBR inhibits cell proliferation by interacting with microRNAs and suppressing telomerase activity.  BBR exerts its anti-inflammation and antioxidant properties, and also regulates tumor microenvironment.

"This review emphasized that BBR as a potential anti-inflammation and antioxidant agent, also as an effective immunomodulator, is expected to be widely used in clinic for cancer therapy." 


American goldthread is not available commercially so we wildcraft goldthread in the shaded forests of northern Idaho.  We can now provide goldthread for people who would like to have this addition to the standard 4-herb Essiac formula.

* IMPORTANT NOTICE:  We do not sell nor are we associated with the trademarked (TM) or registered (R) "ESSIAC" products that are sold by other companies in Canada and the US.  We only sell the herbs so that people can make Rene Caisse's tea in their own homes.  Rene Caisse never registered, patented or trademarked "Essiac" which was simply her last name spelled backwards and was originally derived from a native American herbal remedy for cancer.  The word "Essiac" was in common usage in the 1930s, decades before anyone tried to corner the market by "registering" or "trademarking" the word "Essiac".  Furthermore, we only use the "Essiac" formula which Rene Caisse's best friend, Mary McPherson, officially entered into the public domain in a sworn affidavit in 1994 in Bracebridge, Ontario.  This formula uses Turkey rhubarb root which is much more pleasant tasting than the Indian rhubarb products on the market (which is why Rene Caisse switched to Turkey rhubarb in her final Essiac tea formula).  The website has posted Mary McPherson's "Essiac" formula affidavit here.  This is the formula we use. 

We include sheep sorrel roots in all our Essiac tea products at precise percentages.  The percentages refer to the ratio of sheep sorrel root to the total sheep sorrel content in the formula.

Essiac NorthWest, Humbleweed and many others have all contributed to the Essiac Circle of Friends, a natural society of  like-minded people continuing traditional native herbal healing in the spirit of the Seven Fires Prophecy.  The Essiac Circle of Friends is a cooperative effort to provide the highest quality Essiac tea herbs on the planet.  It is not in itself a corporation or business but some of the people involved have started their own retail outlets to provide these high-quality herbs to the public.   We are the people who plant, grow, harvest and supply these high-quality herbs to those in need.  The Circle has evolved over the past decade with various people contributing to it and then moving on in the ever-changing ebb and flow of life.
