So, what is the big deal about 4 herb and 8 herb, which is better and why are there two kinds of Essiac?
The original Essiac used by the Ojibway Indians in North East Canada for hundreds of years, was made up of four herbs. Those four herbs are Burdock Root, Slippery Elm, Sheep Sorrel and Rhubarb Root.
In the 1800's and the 1900's the landscape of the world was considerably different than in today's time. Back in those days, there were no fast foods, there were no pesticides, no frozen food, no air pollution let alone jet fuel that is found in almost every American! The four herb original formula worked great for everybody.
Nurse Caisse, who was given this original four herb formula back in the early 1900's and who's name Caisse, spelled backwards is Essiac, was the advocate that used the original formula with great success and introduced this product to the United States in the early 20's.
Nurse Caisse partnered with Dr. Charles Brusch (noted research scientist and personal physician to President John F. Kennedy) in the late 1950's and they worked together for eight years developing a more potent and effective version of the original four herb formula. Nurse Caisse and Dr. Brusch saw the future developments in life style in the 20th century and worked to improve the original formula for a modern society.
After eight years of intensive testing, including Dr. Brusch taking the product himself in his fight with cancer, settled on a new formula using the SAME original Herbs BUT adding FOUR new herbs that modify and augment the performance of the original four herbs! Those four new herbs are: Blessed Thistle, Kelp, Red Clover & Watercress. Dr. Brusch announced "this proprietary synergistic blend of eight herbs were found to be the most effective and yielded the best results".
So, there you have it. There is nothing wrong with taking the original 4 herb formula but if you had a choice to use an updated, more effective 8 herb formula, why wouldn't you? My guess is that you probably have 10 times the amount of toxins and pollutants in your system than your counterpart did in 1850!
