Learn why our essiac has a 3 oz. serving size when many other brands have a 2 oz. serving size

A lot of the brands of essiac tea out there call for a 2 oz. suggested serving size, however you will see that we have a 3 oz. suggested serving size listed. Why is that?

The reason is that the other brands you're seeing are 4 herb formulas, whereas ours is an 8 herb formula.

The 4 herb formula is the one that Rene Caisse used before she conducted her research at the Brusch Medical Research Center from 1959 through 1967. She and Dr. Charles Brusch, who was also President Kennedy's physican, conducted research on essiac tea and determined that they preferred the 8 herb formula.


The 8 herb formula is made up of the original 4 essiac herbs, plus 4 additional herbs. The original 4 herbs were: burdock root, sheep sorrel, slippery elm bark and turkish rhubarb root. Rene Caisse and Dr. Charles Brusch added these 4 additional herbs: blessed thistle, kelp, red clover and watercress.

The suggested serving size of 4 herb essiac is 2 oz. because there are fewer herbs in that formula. In order to preserve the original ratios of the 4 herbs but also have room for the 4 additional herbs, there is another 1 oz. of tea that is the suggested serving size for the 8 herb formua.

I hope that helps clarify the discrepany in serving size for various essiac tea formulas!
