Essiac/Flor Essence (PDQ®): Complementary and alternative medicine - Health Professional Information [NCI] - General Information
The manufacturers of Essiac and Flor Essence both state these products can be used in conjunction with other cancer treatments.[1,10] Nonetheless, some proponents of Essiac have recommended that no additional anticancer therapy (such as chemotherapy or radiation therapy) be undertaken while patients are being treated with the mixture. The purported rationale for this statement is that conventional anticancer treatments may alter immune system function and prevent Essiac from working effectively. As indicated previously, no evidence has been reported in the peer-reviewed scientific literature to show that Essiac is an effective treatment for patients with cancer.
