what is essiac tea
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.
