Book excerpt: This is the story of Rene M. Caisse of Bracebridge, Canada and describes her extraordinary perseverance to obtain official recognition of her herbal cancer remedy she called Essiac, her name spelled backwards. Rene Caisse was thrust into a life-long medical-legal-political controversy that still persists since her death in 1978. Rene wrestled with the Hepburn government of Ontario over the operation of her Bracebridge cancer clinic during 1935 to 1941 and her use of Essiac. She refused to reveal her secret formula and legislation demanding the recipe forced the closing of her clinic. The government was embroiled in the dilemma of ensuring their public favour and appeasing cancer patients. This documented research presents a biography of a remarkable woman and her struggle to help "suffering humanity."
