Essiac tea was given its name by Rene Caisse. (Essiac (es-ee-ak) Caisse spelled backwards.) Rene Caisse was a modest Canadian nurse who rediscovered this natural herbal formula to treat cancer sufferers. Essiac Tea consists of four main herbs that grow in the wilderness of Ontario, Canada. The original formula is believed to have its roots in native Canadian Ojibway Indian medicine.

Ms. Caisse helped restore hope in the hopeless, and many claim she restored health and life where only death remained. She helped hundreds both in body and soul. Ms. Caisse received Essiac Tea from a middle-aged female patient who had gotten it from an Ojibwa Indian Medicine Man. The Medicine Man offered his help to the patient because he knew the woman was suffering from breast cancer. The patient recovered from her cancer and saw no reoccurrence during a span of the next thirty years. Rene Caisse used the same recipe on her aunt who was terminally ill with stomach and liver cancer. Her aunt lived another 21 years, eventually dying of old age. Impressed by these successes, Ms. Caisse began to offer the formula to anyone who contacted her. When word of the enormous benefits of the Essiac Tea treatment reached Dr. Charles Brush, a former physician to the late John F. Kennedy, he sought out Ms. Caisse and the two became research partners.

Over the years, many people with various ailments and illnesses have benefited from the Essiac recipe. Although there is no clinical evidence to support the effectiveness of Essiac on cancer or other diseases, it is believed to be beneficial to those suffering from AIDS, Allergies, Arthritis, Alzheimer's, Asthma, Chronic Fatigue Syndrome, Circulatory problems, Diabetes, Fibroids, Hemorrhoids, Hypoglycemia, Impotence, Malignancies, Multiple Sclerosis, Parkinson's, Prostate and urinary problems, Psoriasis, Sleeping Disorders, Thyroid Problems, Ulcers, Warts, and more.
