I was personally taught the correct Essiac tea formula by Dr.Charles Brusch in 1992. My web site, Bulk-Essiac-Tea.com, provides a letter, written by Dr. Brusch and addressed to my mother. He states in this letter that we are using the exact same formula that he and devoped in his research in Camridge, Massachusetts from 1959-1967. Unlike many others, we provide the PROOF of our direct link to Dr. Brusch. Sincerely, Bryan Paulhus
