Abstract
TAMAYO and colleagues, Foresight Link Corporation, Ontario Canada review (198 references) the literature regarding the herbal mixtures Essiac and Flor-Essences, which are sold as nutritional supplements used by patients to treat chronic conditions, particularly cancer.
Background
Evidence of anticancer activity for the herbal teas is limited to anecdotal reports recorded for about 40 years in Canada. Individual case reports suggest that the tea improves quality of life, alleviates pain, and in some cases, impacts cancer progression. Experimental studies using individual herbs have demonstrated evidence of biological activity including antioxidant, antioestrogenic, immunostimulant, antitumour and anticholeretic actions. However, research demonstrating these positive experimental effects has not been translated to the clinical setting.
Methodology
No clinical studies of Essiac or Flor-essence are published; however a clinical study is being planned for the British Columbia Cancer Agency by the University of Texas-Center for Alternative Medicine (UT-CAM) and Tzu-Chi Institute for Complementary and Alternative Medicine.
