<p>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.

This documented research presents a biography of a remarkable woman and her struggle to help "suffering humanity."</p>
