People use Essiac for a multitude of health conditions, most notably cancer. However, another common use for Essiac is in treatment of diabetes. The discovery of the association between diabetes and Essiac occurred when one of Caisse’s patients with both colon cancer and diabetes not only saw remission of her cancer on Essiac, but also claimed that her diabetes disappeared.

This result was so astounding that even Dr. Frederick Banting, a Nobel laureate and one of the primary discoverers of insulin, became interested in researching Essiac further. Dr. Banting wanted to investigate the possible ability of Essiac to regenerate the pancreas’ ability to produce insulin and thus treat diabetes, but the research never happened because one of the stipulations was that Caisse close her clinic until after the research was completed; Caisse found this unacceptable due to her number of cancer patients.

Toxin Removal

Many Essiac proponents believe that Essiac’s detoxifying property is one of the main physiologic mechanisms that makes it helpful in diabetes. With type II diabetes in particular, the pancreas loses function due to exposure to toxins from poor diet, environmental pollutants, and attacks from microbial pathogens. Regular use of Essiac tea reportedly flushes these toxins from the body by neutralizing them and allowing the body’s other organs (such as liver, kidney, skin) to remove them. This allows the pancreas to regain function and return to normal levels of insulin production.

This theory, however, has not been proven with laboratory or clinical studies. Also, given that type II diabetes is related more to insulin insensitivity, rather than insulin deficiency, this theory seems unlikely to be the case in type II. With type I, though, where the problem is insufficient insulin production by the pancreas, this theory may be explanatory if Essiac can help clear the auto-antibodies and heal the pancreas.

Effects of Burdock Root

Another mechanism by which Essiac likely helps diabetes is through the action of one of its constituent herbs. Burdock root appears to be the important root in diabetes. This root has been used to reduce blood sugar for centuries and at least one study has shown that a mixture of burdock root and astragalus root improved blood sugar in diabetics, among other beneficial actions.

Diabetes remains one of the major diseases for which Essiac possesses reported therapeutic effects. It likely derives its usefulness in diabetes from its detoxification property and the ability of burdock root to act as a hypoglycemic agent. One must exercise caution when using Essiac or any substance with the potential to lower blood sugar, though. Hypoglycemia can be life-threatening. It is important to talk to a health professional when using a hypoglycemic agent and to inform one’s doctor of ALL medications and supplements being used. Whether it is a prescription drug or not, overuse or the improper combination with other drugs or supplements can be harmful or even fatal.

Some Basic info on Diabetes


Diabetes occurs when the body either does not produce enough insulin or has an inadequate response to insulin, which is one of the main hormones essential to regulation of blood sugar levels. Specifically, insulin’s main role is signaling cells to uptake sugar from blood and thus decrease blood sugar.

Diabetes comes in two basic types: type I and type II. Type I diabetes is an autoimmune disease in which a person’s body produces molecules called auto-antibodies that attack the person’s own pancreas, the organ that produces insulin. Type II diabetes occurs when a person produces enough insulin, but cells throughout the body have become resistant or insensitive to its effects. This type of diabetes largely develops due to lifestyle, e.g. obesity, lack of exercise, and poor diet.

Common symptoms of diabetes include:

  • Increased thirst, urination, and eating,
  • Weight loss,
  • Fatigue,
  • Nausea/vomiting,
  • Abdominal pain,
  • Recurrent infections

With conventional medicine, type I diabetics always require insulin, while type II diabetics can be treated with oral medications that decrease blood sugar or improve insulin sensitivity. Type II diabetics may also eventually require insulin injections if oral medications fail to control the disease. Whenever using a hypoglycemic medication, or blood sugar-lowering drug, it is essential to be aware of the symptoms of hypoglycemia (low blood sugar):

  • Sweating,
  • Shaking,
  • Rapid heart rate,
  • Changes in vision (blurry vision, seeing double),
  • Confusion or abnormal behavior

If these symptoms occur, it is vital that one check his/her blood sugar and eat/drink something containing sugar.
