What is Essiac Tea? Essiac is a pleasant-tasting four-herb tea which was developed from a native American remedy by Canadian nurse Rene Caisse. According to the research of Sheila Snow and Mali Klein the original, native formula consisted of eight herbs.ccording to Rene Caisse, sheep sorrel roots are very essential to the formula. Therefore, if sheep sorrel roots are not included, it is not authentic Essiac tea. Unlike Chinese green tea or black tea, Essiac tea does not contain caffeine. Rene Caisse called her tea Essiac--her surname spelled backwards.
As with many alternative remedies, the exact composition of Essiac is unclear, but it reportedly contains burdock (Arctium lappa), sheep sorrel (Rumex acetosella), slippery elm bark (Ulmus rubra), and Indian rhubarb (Rheum officinale) or turkey rhubarb (Rheum palmatum) .rom the 1920s through the 1970s, Essiac was promoted as a cancer treatment by Rene Caisse, a Canadian nurse, who claimed that it had been given to her by an Ontario Ojibwa patient she treated. However, this has never been substantiated.
