Rene Caisse's first recorded success with Essiac was referred to as Mrs M who used the tea in 1892 for advanced breast cancer. Nurse Caisse attended her in 1922, and was given the original formula at that time.
Caisse kept records of her patients from 1924 onwards, and those that remain, along with patients discussed in her articles, are available here.
In 1959 Rene Caisse provided a senior doctor at Dr Brusch's Clinic with Essiac for research. The case studies from these trials were sent to Rene Caisse and are available here.
Cantea/Essiac has been used since 1992, and some of the patients have been kind enough to send in their stories and in some cases their medical records and diagnosis. Results of trials I funded in 1995 are also included.
