Caisse Tea

All about Caisse Tea

Caisse Tea is a blend of four organically grown herbs from which an infusion is made.

This packet will make a total of 9 litres before straining – amazingly economical! The herbs are blended according to Rene Caisse’s Formula.

Rene Caisse was head nurse at the Sisters of Providence Hospital in Ontario, Canada. 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 to her by an Ojibwa herbalist. After witnessing its curative effects on a member of her own family, Rene Caisse developed her Essiac formula as an herbal cancer treatment. Essiac is Caisse spelt backwards.

It is not offered as an effective cancer treatment, since evidence is largely anecdotal. Clinical trials are lacking. However, the herbal formula is an excellent detoxifier and blood cleanser to support any health regime.

Please note that since Rene Caisse sold the formula Essiac™ has been a registered trade mark. We do not sell Essiac™, but we sell products based on Renée Caisse’s formula.

Caisse Tea Ingredients in Caisse Formula

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 but later discovered that this imported product was more potent than native rhubarb.

These are packed in two sachets for mixing prior to use:
Burdock Root / Sheep Sorrel 82g
Slippery Elm / Rhubarb Root 8g

Important Note: The interaction between the herbs during the brewing process is very important, which is why some of the herbs are powdered and others chopped or fine cut. Although it may seem more convenient to supply all herbs in powdered form this would limit the interaction.

Caisse Tea - Directions for Brewing

Thoroughly mix the contents of the two packages in the packet.

Stage 1
Stage 2
Caisse Tea - Storage

The bottles are best stored in a fridge, but a cool dark place is likely to be sufficient.

If the tea develops mould, throw it away and do not use it.

Do not microwave.

The tea should be pale to mid brown, or occasionally greenish.

The texture should be very slightly viscous, not oily.

The taste should be pleasantly mild with a slightly woody flavour.

Caisse Tea - Directions for Use

Rene Caisse recommended 30ml in 60 ml of hot water once a day (Some people divide this into two doses morning and evening).

Sip like tea, preferably before bedtime.

Food should not be eaten within one hour of drinking the tea.

History of Essiac

The Essiac formula was developed by Rene Caisse, (Essiac is Caisse spelled backwards.) Rene Caisse was head nurse at the Sisters of Providence Hospital in Ontario, Canada. Ms. Caisse claimed that in 1922 the formula had been given to her by an elderly patient whose breast cancer had been cured by taking a traditional native American herbal remedy given to her by an Ojibwa herbalist.

Rene was fascinated with her story and wrote down the names of the herbs the woman had told her. A few months later Rene’s aunt was diagnosed with stomach cancer. Doctors gave her six months to live. Rene asked if she could try the tea under the supervision of the doctor. Permission was granted and her aunt lived another twenty one years with no recurrence of cancer. Rene began researching her formula and treating patients with amazing results.

The startling results claimed for this simple herbal remedy could not be ignored. When The Canadian Ministry of Health and Welfare and Parliament threatened to imprison Ms Caisse for using unorthadox treatments, 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-five thousand signatures were collected on the petition.

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 felt that those that had been cured either recovered due to orthodox practice or were simply misdiagnoses of cancer. 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, 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. She died in 1979.

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 slight weight loss occurred in some treated animals. However, The National Cancer Institute 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. 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. No other results of laboratory (in vitro) or animal (in vivo) studies of Essiac have been reported in the peer-reviewed, scientific literature.” Source: National Cancer Institute (not a pro-Essiac source!) Abstract:

So, whatever the truth may be regarding cancer, the herbal formula, be it taken as tea or tincture, is beneficial for overall health and wellbeing.

Caisse Tea versus Caisse Tincture

We stock both the original Caisse Tea Herbs for you to make up and Caisse tincture from the same source.

Some people believe the Tincture is superior to the tea, see the table below. Although there is no evidence that Renée Caisse ever used tinctures she did use an injectable form of the tea.

Tea Tincture
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, even if boiled, and others evaporate away at these temperatures. 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 difficulties for patients with gastric problems. The concentration of the tea is also rather unpredictable. 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 and Storage 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.

We believe that both Caisse Tea and Caisse Tincture have their merits.

Tea proponents argue that it is the method of preparation that produces an efficacious end product.

Alcohol soluble principals are unimportant in this regard, whereas compounds such as complex saccharides formed by brewing the herbs together are very important. If you use the tincture but are susceptible to alcohol, the alcohol can be removed by simply adding a little near boiling water and it will quickly evaporate.

Essiac for Cancer in Animals

Since 1922, Essiac, an herbal tea mixture, has been used with anecdotal great success in cancer treatment in Canada. Although it has not been “approved” by conventional medicine, some 55,000 people signed petitions in support of its use when Canadian medical bureaucrats tried to prohibit its use.

Although popularized in the early 1920’s, the formula has been around for centuries. It consists of a mixture of burdock root, slippery elm, sheep sorrel and Indian rhubarb. The formula is believed to have been originally developed by the Ogibway Indians.

The dosage in animals needs to be adjusted to the size of the animal. Essiac International recommends the following:

For converting human dosages to animal dosages, a safe starting dose as a general rule of thumb is to calculate the dosage based on the weight of your animal in proportion to a human. (e.g. 4 capsules for a 160 lb. person equals 1 capsule for a 40 lb. dog) However, since animals have higher metabolic rates than humans, higher dosages are usually needed and should be given with slow, incremental increases, watching for adverse reactions such as vomiting, loose stool and depression.
