Sworn Affidavit of Recipe


Mary McPherson's Affidavit

The certified copy of Mary McPherson's two-page affidavit (below) was provided by the Commissioner of Affidavits of the Town of Bracebridge, Ontario.  Mary McPherson's affidavit is the only verifiable, legal evidence of Rene Caisse's Essiac formula. 

This evidence will hold up in a court of law because it is the only official evidence, under Oath, recorded for the public record in a government office, which gives the original, authentic Essiac formula that Rene Caisse was using after more than fifty years of research.  (The Seal of the Town of Bracebridge does not show up on this scanned image because it is crimped on the paper.)

Mary McPherson knew the Essiac formula because she was the only person (other than Rene herself) who was allowed to make Essiac tea to give to Rene's cancer patients.  This is the same Essiac tea formula which helped so many cancer patients in Rene Caisse's clinic in Bracebridge, Ontario, as stated by the doctors that observed the results.  It is true that Rene Caisse did experiment with various herb combinations throughout her life, but the affidavit below reveals the final formula that she settled on after many years of experimentation with real cancer patients and laboratory mice. 

Regardless of what some websites claim, this document reveals that the "Essiac" formula and recipe was officially placed in the public domain for everyone's use on December 23, 1994.  Mary McPherson's affidavit was also verified by Sheila Snow and Mali Klein in their book ESSIAC--THE SECRETS OF RENE CAISSE'S HERBAL PHARMACY (p. 14) and can be seen in the appendix of Mali Klein's book THE ESSIAC BOOK.

IMPORTANT NOTE:  Notice that the "1 ounce of herb mixture" is not a weight measurement because it is measured with "a measuring cup" that measures fluid ounces, which is a volume measurement of water.  It is important to mention that Rene Caisse did not use a weight measurement when adding the herb mixture to boiling water.  She used volume measurement for the combined dried herbs with fluid ounce measurements.  This makes the recipe seem confusing unless one realizes that one cup of the dried herb mixture does not weigh as much as one cup of water (which weighs 8 ounces).  That is, one cup of "herb mixture" does not weigh 8 fluid ounces because the dried, powdered herbs are lighter than water. 

Rene Caisse did weigh the individual herbs before mixing them together.  That is, the "1 pound of sheep sorrel herbs", "1/4 pound of slippery elm bark" and "1 ounce of Turkish rhubarb root" are weight measurements.  6 1/2 cups of cut burdock root is, of course, a volume measurement and it is equivalent to 24 ounces in weight when pieces are "the size of small peas".  [SECRETS OF RENE CAISSE'S PHARMACY, p. 14] 

It is also important to note that Rene Caisse used the whole sheep sorrel plant.  Nurse Caisse stated that sheep sorrel roots are "very essential" to the Essiac formula.
