Frequently asked questions

  1. What is the difference between Essiac and other herbal products?

    Essiac is Canada's original herbal supplement and has been used over the course of a century. Since the first cup of Essiac tea was made in 1922, the product has been trusted by consumers as a 100% natural cleansing supplement.

  2. Why does Essiac contain only four active herbs when other supplements have more?

    Since 1922, Rene Caisse’s formula has used four herbal ingredients. Those herbs are still used in Essiac today to work synergistically to promote the elimination of toxins and waste from the body’s organs and bloodstream. Other supplements that may use a combination of Essiac's ingredients also contain other herbs, in some cases that have been identified to have negative side effects.

  3. What are the active herbal ingredients in Essiac?

    Essiac's formula contains a proprietary ratio of burdock root (arctium lappa), sheep sorrel leaves (rumex acetosella), slippery elm bark (ulmus fulva), and Indian rhubarb root (rheum officinale).

    How do those herbs help the body?

    • Burdock root has been shown to have anti-inflammatory, antioxidative and antiproliferative properties.
    • Sheep sorrel leaves are used as an anti-inflammatory, and to help the body maintain healthy skin and immune functions.
    • Slippery elm bark is used as an anti-inflammatory, can help sooth the stomach and intestines, and supports digestion.
    • Indian rhubarb root is a diuretic and has anti-inflammatory and antioxidative properties.
  4. Why does the liquid extract contain alcohol?

    Essiac uses the same ratio of herbs that Rene Caisse specified in her original formula. The liquid extract contacts grain alcohol as a non-medicinal ingredient, which contributes to a more effective absorption of the medicinal ingredients. Alcohol is commonly used as a solvent for herbs, as it aids in the extraction and digestion of non water-soluble ingredients. Essiac still manufactures the original powder, but the liquid extract and capsules ensure a controlled extraction and concentration of active ingredients.

  5. Where do you source your herbs?

    All of the herbs used in Essiac’s products are sourced and extracted for their active properties in Canada.
