Essiac: It is impossible to explore the field of alternative
cancer remedies without running into the word “Essiac”. Essiac is
an herbal remedy said to have originated with the Indians of
northern Ontario. In 1922, an elderly patient gave the formula to
Renée Caisse, a nurse in an Ontario hospital. (Essiac is “Caisse”
spelled backward.) In 1924, Caisse tried the formula on her mother,
who had been diagnosed with inoperable liver cancer. After using
the formula, Caisse’s mother was said to have lived for another
eighteen years. Caisse then devoted her life to treating cancer
patients with the formula free of charge. By 1938, with hundreds of
testimonials to its healing powers, Caisse approached the Canadian
parliament for recognition of the formula but was turned down.
Caisse died at age ninety in 1978, having kept the formula a secret
throughout her life.

Several persons have laid claim to ownership of the formula,
reported to have been bequeathed to the Resperin Corporation and to
David Fingard via Matthew Dymond, former deputy health minister of
Ontario. Now the list of ingredients and various formulations for
Essiac circulate widely in alternative cancer publications. The
formula is prepared as a tea from various proportions of at least
four (sometimes six) herbs, including Indian rhubarb (Rheum
palmatum), sheep sorrel (Rumex acetosella), slippery elm (Ulmus
rubra), and burdock root (Arctium lappa). The most potent herb, the
strongly laxative Indian rhubarb, constitutes the smallest part of
the formula.
Essiac is not approved by any authority for treatment of cancer.
Attempts have been made by its advocates to have it accepted into
clinical trials. In 1978, the Canadian government allowed Laval
University and the Toronto General Hospital to investigate the
formula in cancer patients. Family practitioners were allowed to
supervise terminally ill cancer patients on an Essiac regime when
no other treatment was possible. The formula was apparently of no
benefit in the vast majority of these cases. Evaluation of the
formula in NCI’s tumor screening systems also has produced no
positive results.
