The Rene Caisse herbs are now available in Ireland as premixed dried Caisse herbal tea blend ready for use.

This authentic recipe has been handed down to me directly from one of Ireland’s most respected herbal medicine practitioners, Judith Hoad of Co. Donegal.  In Judith’s (semi) retirement, she has entrusted me with the authentic formula so that I can continue to provide the Caisse herb blend at a non-profit price, exactly how Judith herself has provided the Rene Caisse herbs to people over her life-long career.

The Rene Caisse herbs are organic dried herbs, mixed and supplied by a certified & registered organic herb supplier in the UK.   This means that I can guarantee the herbs are grown and harvested by registered organic growers to EU standards, dried and mixed to just the right genuine Rene Caisse herbal formula.

Supplied in convenient 60g packs for €14 each, plus postage to anywhere in the world, one packet is enough to last one person one year.

Rene Caisse Formula Essiac Dried Herbs

We provide the herbs to make Essiac tea just like Rene Caisse made it!  Our information is based upon the research and documentation of Sheila Snow* and Mali Klein, who have collectively written five books about Rene Caisse and Essiac tea.  According to their research and documents obtained from the Sloan-Kettering Cancer Research Institute, Rene Caisse stated that sheep sorrel roots are “very essential” to the Essiac tea formulas.  Our site is one of only a few sources worldwide for the herbs to make Essiac tea with the ENTIRE sheep sorrel plant, roots included.  Sheep sorrel roots are much more potent than the leaves and the roots contain nutrients which are not present in the leaves.  In fact, the potent sheep sorrel roots don’t even taste like the leaves–as if they are an entirely different herb! 

Beginning in the 1920s Rene Caisse experimented with terminally ill patients and laboratory mice using various herbal combinations and developed several formulas for promoting healing in a variety of illnesses, including cancer and diabetes.  Her most well-known formula is the classic four-herb Essiac tea:  Burdock root (cut), Sheep Sorrel (whole herb, powdered, including root), Slippery Elm inner bark (powdered), and Turkey Rhubarb root (powdered).  This was the formula that Nurse Caisse was using near the end of her life after more than 50 years of research.  Rene Caisse kept her formulas secret except for only a handful of people.  After her death, Dr. Gary Glum released the four-herb formula to the general public after purchasing it in the US in 1985 from one of Rene’s former patients.  Later, Rene’s best friend, Mary McPherson, recorded a sworn affidavit containing the same four-herb Essiac formula, formally entering the classic Essiac formula into the public domain for everyone to use.  Mary McPherson was the only person that Rene allowed to make Essiac tea for her cancer patients.  (For more information please read the notice at the bottom of this page).

Sheep Sorrel Root

We go the extra mile to provide Essiac (pronounced ess-e-ack) herbal tea that includes Sheep sorrel roots, as its developer and namesake, Canadian nurse Rene Caisse, (pronounced Reen Case) did.

ssroots.…there is a missing ingredient in almost 100% of the Essiac being sold in today’s world.  It is sheep sorrel roots. Although sheep sorrel herb (Rumex acetosella) is a standard ingredient in almost all Essiac, its almost always just the stems, flowers and leaves – the arial parts – but no roots.

According to Rene Caisse, leaving out the sheep sorrel root is leaving out the most important ingredient.

“You can buy the crushed leaves but they are no good alone.  I found this out when I needed so much, when treating three to six hundred people afflicted with cancer every week for eight and a half years.  I do know that the whole plant is needed.”  – Rene Caisse to Dr. Chester Stock, Memorial Sloan-Kettering Cancer Center, January 1975. (Sheila Snow Fraser Essiac Archive Collection) 

Sheep sorrel root is generally not commercially available, and that does present a challenge for companies trying to produce Essiac on a large scale.  But we source our herbs from accredited organic suppliers and as each supplier is registered, each of our herbs can be traced back to it’s source.

Rene Caisse preferred Turkey Rhubarb in her later recipes due to its effectiveness, and it was also easier for patients to digest, it did not result in the nausea caused by Indian Rhubarb in some people. (Source: The Essiac Book by Mali Klein)
