Welcome to Rene Caisse Tea – Home of Organic Essiac Tea with Sheep Sorrel Roots included!

Welcome to ReneCaisseTea.com, where we go the extra mile to provide Essiac tea that includes sheep sorrel roots, as its developer and namesake, Canadian nurse Rene Caisse, did.

home....there is a missing ingredient in almost 100% of the Essiac being sold in today's world.  It is Sheep sorrel root. 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 root.

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, Sloan-Kettering Cancer Institute, 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.

We are a small business focused on providing quality Essiac, 'with the root', and reliable, well-documented Essiac information.  Our herbs are either Certified organic, or responsibly wildcrafted from unpolluted areas.  We wildcraft our sheep sorrel root from the country in Montana and Idaho. All of our herbs come from the U.S., and are grown, for the most part, within our home region here in the Inland Pacific Northwest.

We are pleased to offer pre-mixed, ready to brew Essiac herbs and the perfect reading companion,  The Complete Essiac Essentials.  This book has all the necessary information on what to look for whether you are buying, wildcrafting, or growing the herbs. It walks you through making your own mix from scratch. including the 'handy half-pounder' recipe, and includes detailed step-by-step instructions for making the decoction.  Sample programs are offered for the best way to work with Essiac and the other formulae that Rene Caisse is known to have used. We also offer a reprint of the 1963 booklet written by Rene Caisse herself,  I Was Canada's Cancer Nurse, .....and more!  visit the store

About the Essiac formula......There are many different versions of Essiac being sold today, but the original Native American 8-herb formula was put on the shelf in the 1920s and has not seen the light of day since.  In the modern day 8-herb Essiac products, herbs are often added that Rene Caisse is not known to have ever worked with, such as Blessed thistle and Kelp. Archival evidence suggests that the original 8 herbs were: Burdock (Arctium Lappa), Sheep sorrel (Rumex acetosella), Slippery elm (Ulmus Rubra), Turkey rhubarb (Rheum palmatum), Red clover (Trifolium pratense), Watercress (Rorippa nasturtium aquaticum), Periwinkle (Vinca major/minor), and Goldthread (Coptis trifolia).  However, very early on, Rene Caisse narrowed the Essiac formula down to what several years' of her own research found to be the four main active ingredients: Sheep sorrel, Burdock, Slippery elm and Turkey rhubarb. 

Rene did work with other herbs besides the four in her classic Essiac formula, including some of the original 8 herbs.  She also patented a kidney remedy, and made a salve for radiation burns.  She utilized several variations of the Classic 4-herb Essiac formula memorialized and made public 16 years after her death by her long-time friend and helper Mary McPherson in the form of an affidavit filed with the Bracebridge Ontario Town Clerk.

There is currently no 8-herb Essiac being sold that matches the hand-written paper upon which Rene listed the original Essiac herbs, as reproduced in The Essiac Book (Mali Klein, 2006) and The Complete Essiac Essentials (Sheila Snow/Mali Klein, 2010).

Rene Caisse Tea.com uses the classic four-herb Essiac that is in the public domain. People have a right to know exactly what they are buying, especially when it comes to public domain formulas.  Therefore we include the percentage of each herb in the mix, right on the label.

At the root of it........Sheep sorrel root is a clearly verified important part of the Essiac formula that is absent from almost all of the Essiac sold today. ReneCaisseTea.com's Essiac tea contains 65% sheep sorrel root in proportion to the arial (above-ground) parts of the plant. We use both wild-harvested Sheep sorrel root and organically grown whole herb Sheep sorrel, and also include a small percentage of the arial parts of the plant.  Rene Caisse was reported to harvest the entire Sheep sorrel plant, including the roots.  In keeping with that we use, and urge all those who produce Essiac or Essiac-like products, to use the entire Sheep sorrel plant.

Small is beautiful......Essiac in your own backyard!  The ideal way to get the best Essiac herbs is to grow them in your garden! This is a realistic, economical alternative that will ultimately generate the raw materials to make your own Essiac. Like so many worthy endeavors, growing the Essiac herbs is best done on a small scale by hand, which allows for much greater care to details such as hand-weeding and timing the harvest just right. Large scale harvesting requires that sheep sorrel plants be allowed to grow tall and past their prime  - so that they are lanky enough to be caught by the mowing machinery.  When Sheep sorrel root is hand-harvested selectively, it ensures a continuing supply because there is no plow wiping out an entire colony or planting. Essiac truly is meant to be looked after and tended to 'by the people,'  and Rene Caisse meant her herbal decoction to be 'for the people.'

Why not just get sheep sorrel in the wild? For having a very wide range, sheep sorrel is frustratingly hard to find in any one place in any significant quantity in the wild. Where you will often find it is flourishing along the roads and in other toxic places. The root is very small so it takes hours to collect what will end up being much less once dried. However, both sheep sorrel and Burdock (Arctium lappa) are found growing in the wild all around the world, and sheep sorrel is quite amenable to being dug up and re-deposited in your garden. Although not normally classified as a 'noxious' weed, here in the U.S. many states consider sheep sorrel a 'nuisance' weed.

In spite of being sprayed and inundated with car exhaust, sheep sorrel is a pioneer kind of plant, and persists in surviving no matter what kind of  herbicide is thrown at it by the roadside weed control folks.  A weed-sprayer working for Idaho County once commented to me, "You can't kill it!"  This draws an interesting parallel when considering larger questions of mortality.  Pioneer plants are known to be the first step to renewal of devastated environments. Could it be that sheep sorrel is drawn to where it is needed, to help detoxify and heal? Its gentle resilience is a compelling hallmark of how so many herbs work in this world. DSCN0093

The main point is that sheep sorrel from polluted places can't be used in Essiac.

Burdock can be difficult to harvest in the wild too, due to the need to dig down several feet into sometimes unyielding soil, to get the entire root.  Burdock root should be harvested in the first year, before the plant produces any 'burs'.

Back to the garden.....Burdock and sheep sorrel are not hard to grow, harvest and dry.  You can grind them in a (clean!) coffee mill.  The third Essiac ingredient, slippery elm (Ulmus rubra), is widely available and should be easy to find at your local health food store. Its best to buy it because it is hard to powder, and it takes at least ten years for the tree to be mature enough to survive the necessary sacrifice of a branch.The final ingredient, Turkey Rhubarb (Rheum palmatum), although easy to grow, and beautiful, is ideally not harvested until it reaches peak potency in its sixth year.  The dried root is a bit challenging to access commercially - don't settle for less than Rheum palmatum.  The Complete Essiac Essentials is the ideal guidebook and reference, with everything you need to know to do Essiac right - how to grow, harvest, and make and take the various Essiac formulae, all in one book.

Essiac tinctures and capsules....There is no evidence that Rene Caisse ever used Essiac except in decoction, and this is why we do not offer Essiac in capsule or tincture form.  A decoction by definition requires boiling. Herbs have varying properties depending on whether they are used fresh, dried, tinctured, in infusion (steeped) or in decoction (boiled and steeped). I am not certain which category taking herbs in pill form would translate to.

Sheep sorrel, Slippery elm, Burdock and Turkey rhubarb have historically been used in a variety of ways, both as foods and/or medicinally. These four herbs in combination seem to have a synergistic effect that has, to date, not been adequately tested in the laboratory.  Certainly they have never been tested using the public domain Essiac formula, with Sheep sorrel roots included and using organic, top-quality herbs. This really does deserve some good research!

The Snow/Klein collaboration. We hang our hat on the research and documentation of Sheila Snow and Mali Klein, who have collectively written five books on Rene Caisse and Essiac. The newest book, The Complete Essiac Essentials (March 2011), is the culminating edition of the earlier Snow/Klein trilogy: Essiac Essentials (1999), Essiac the Secrets of Rene Caisse's Herbal Pharmacy (2001), and The Essiac Book (2006).  It represents the gold standard in Essiac reference books. It really stands alone in its class. The straight story, from the ultimate source - Rene Caisse's closest friends and helpers. And, coming in 2014, Book Six:  Black Root Medicine: the Original Native American Essiac Formula,by Mali Klein.

The source.  Rene Caisse and Mary McPherson. Sheila Snow and Mali Klein knew the wisdom in 'going to the source' when looking for those little answers that inform much bigger questions. Sheila's personal acquaintenance with Rene Caisse was invaluable in this regard.  Rene's long-time friend and helper, Mary McPherson, also worked directly with Sheila and Mali over the course of more than ten years.  She helped immensely in giving insight into what made Rene tick. When Mary passed away in 2006, she bequeathed some very special Essiac treasures to Sheila. Sheila, who passed away in 2008, had amassed quite a collection of Essiac history, which Mali has now inherited.  Mali shares some new material from the Sheila Snow Fraser Essiac Archives in  The Complete Essiac Essentials (along with a very thought-provoking Appendix 4, the prelude to Book Six:  Black Root Medicine the Original Native American Essiac Formula).

Sheila. It is Sheila Snow who discovered the documentation of the importance of sheep sorrel root in the Essiac formula.  The Memorial Sloan-Kettering Cancer Center gave her copies of Rene's correspondence with Dr. Chester Stock during the 1970s when MSK was researching Essiac. (The research had promising preliminary results, but there were several issues which resulted in inconclusive findings.)

Mali. Mali Klein, in addition to contributing her literary genius, has also given further service on behalf of Essiac.  She established Clouds Trust, a registered Essiac charity in the UK that has now been in operation for over 15 years, legally providing Essiac tea, sheep sorrel root included, to any British citizen who wishes to have access to it.

For 20 years Mali has been growing and experimenting with the Essiac herbs.  If it were not for Mali, the world would not have an Essiac reference book that has no comparison.  Her dedication to excellence in whatever she has chosen to undertake has ensured that the true story of Rene Caisse and Essiac will never be lost. And next, she will be taking a very timely look at the original 8-herb indigenous formula, and its implications in this new millennium.

Rene Caisse Tea is doing its part by replicating Rene Caisse's Essiac formula with sheep sorrel roots included, and by being a trusted online source of Essiac information and history.  We are committed to keeping Essiac available and affordable for anyone who wishes to take it. "We all have the right to benefit from Essiac because no one can stop us making it, no one can stop us taking it and no one can stop us deciding how and when we're going to do it." - Mali Klein, The Essiac Book

Rene Caisse meant for Essiac to contain sheep sorrel root, and we are spreading the word! We owe it to the future to hang on to a few of the useful things people knew before their time. There are many valuable things yet to be rediscovered about herbs and their role in our health and well-being. "No Army is as powerful as an idea whose time has come." - Victor Hugo

....Thank you, Rene! :)
