The Essiac formula was developed by Renée Caisse, a head nurse at the Sisters of Providence Hospital in Ontario, Canada, as a herbal cancer treatment. (Essiac is Caisse spelled backwards.) Ms. Caisse claimed that in 1922 the formula had been given to her by a patient whose breast cancer had been cured by taking a traditional native American herbal remedy given her by an Ojibwa herbalist.
The herbs were usually administered as an infusion, hence the term “Essiac Tea”. Please note that since Rene Caisse sold the formula for $1 Essiac™ has been a registered trade mark. We do not sell Essiac™, we sell products based on Rene Caisse’s formula!
So startling were the results claimed for this simple herbal remedy that it could
not be ignored. The Canadian Ministry of Health and Welfare and the Parliament became
involved. Friends, former patients, and grateful families petitioned the Canadian
government committee for Rene Caisse's right to administer the remedy to anyone who
asked for it without the threat of interference from the authorities. Fifty-
In 1938, Essiac came within three votes of being legalised by the Ontario government as a remedy for terminal cancer.
In 1939 a Royal Cancer Commission was set up to investigate alternative cancer therapies. The commission classified cases as recovery due to orthodox techniques or simple misdiagnosis of cancer, despite having been diagnosed with cancer by two or more qualified physicians. Finally the Commission concluded that "the evidence adduced does not justify any favourable conclusions as to the merits of Essiac as a remedy for cancer ...".
Thousands of patients were treated with this herbal mixture, mostly at Rene Caisse’s own clinic, which she set up in Bracebridge, Ontario with the help of the local town council. In 1942, fearing imprisonment, Rene Caisse closed her clinic, but continued to treat patients from her home.
In 1959, at the Brusch Medical Centre in Massachusetts, Rene treated patients under the supervision of 18 doctors. Charles Brusch MD, President J.F. Kennedy's physician, is said to have declared that "Essiac has merit in the treatment of cancer."
In 1977, shortly before her death the following year, Rene Caisse finally gave her formula to the Resperin Corporation, selling the rights for just $1 as the company promised to do clinical trials to prove that Essiac could cure cancer. Disappointed with the outcome of this agreement, Rene Caisse also gave her formula to some other trusted friends. However, from this point on the term “Essiac” has been a registered trade mark and so the name cannot be used for similar products based on the same original Ojibwa formula.
In 1982 the Canadian government ruled that clinical evidence did not support Essiac as an effective cancer treatment. However, under Canadian Emergency Drug Release Program, Essiac could be obtained by physician request.
However, the controversy over Essiac has carried on through the years.
The mixture remains worth investigating, not just because of persistent anecdotal reports, but because its component herbs have individually been demonstrated to have some degree of anticancer properties in independent tests.
No acute toxicity was seen with Essiac in the MSKCC tests, although there was said to be a slight loss of weight in treated animals. The National Cancer Institute, however, claimed to see lethal toxicity at the highest concentrations of Essiac given to animals. (thought to be double the suggested human dosage)
In July 1991, the Canadian Journal of Herbalism published an article, "Old Ontario Remedies", about Essiac. The article gives specific information on the ingredients of Essiac and includes descriptions of the herbs. Sheep's sorrel, for example, as a folk remedy for tumours.
The article also warns of high oxalic acid content in two of the herbs, making the remedy unsafe for persons with kidney ailments or arthritic conditions. The article concluded:
"Essiac is not a hoax or a fraud. To hear experiences described by the patients themselves cannot help but convince observers that dramatic and beneficial changes definitely took place in many but not all of those who received the remedy. Although the focus on Essiac has been as a cancer treatment, it alleviated and sometimes cured many chronic and degenerative conditions because it cleanses the blood as well as the liver and strengthens the immune system."
“In 2004, a mixture of the Essiac herbs showed a decreased proliferation in a prostate
cancer cell line.[1] No other results of laboratory (in vitro) or animal (in vivo)
studies of Essiac have been reported in the peer-
So, whatever the truth may be regarding cancer, the herbal formula is an excellent
blood cleanser.
The tincture is reported to be more effective than the tea due to
extraction by alcohol.
To remove the alcohol simply add a little near boiling water
and it will quickly evaporate.
Sheep Sorrel (Rumex acetosella)
Burdock Root (Arctium lappa)
Slippery Elm (Ulmus fulva)
Turkey Rhubarb (Rheum palmatum)
Turkey Rhubarb grows in China. The roots are harvested when the plants are at least six years old. Rene Caisse began using the domestic rhubarb root and later discovering that this imported product was more potent than native rhubarb.
It is also thought that Rene Caisse added Red Clover when in season. And this is
an important point. Rene Caisse gathered most of the herbs she used herself at the
peak of freshness and activity.
This is not something we can all do easily, even
if we could find and identify the herbs in an unpolluted state.
We stock both the original Caisse Tea Herbs for you to make up, and Caisse tincture from the same source.
Tea proponents argue that the method of preparation is what produces an efficacious end product, and that the alcohol soluble principals are unimportant in this regard, whereas compounds such as complex saccharides formed by brewing the herbs together are very important.
There is no evidence that Rene Caisse ever used tinctures, although she did use an injectable form of the tea.

Extraction
|
The tea is made by boiling in water, steeping and boiling again the next day. Important
active principles of most herbs are insoluble in water, |
Alcoholic extraction enables a much more complete extraction of the active principles than is possible with boiling water and produces a much more concentrated product. |
|
Serving Size |
You may need large amounts of the tea several times a day to obtain the required
dose. This may cause |
Extraction by alcohol produces a more predictable concentration. Servings can be measured in drops. Alcohol can be removed by adding near boiling water for those sensitive to it. |
|
Preparation
|
The tea requires lengthy preparation to boil the active ingredients out of the herbs. As the final product is not preserved, relatively small amounts must be made often and stored in a cool, dark place |
Caisse tincture will last at least 5 years at normal room temperature, preserved by the alcohol content. Assuming the bottle is brown or blue glass, normal light will not effect it. |
