Looking back, Essiac tea, also known as the tea of life,  is a herbal blend that gained popularity in the early 20th century, particularly in Canada. It’s often touted for its supposed health benefits, including

  • cancer-fighting properties
  • immune system support
  • detoxification effects

Essiac Tea

The formula for Essiac tea was popularized by a Canadian nurse by the name of Rene Caisse, who reportedly learned about it from a patient in the 1920s.

The original formula, which Caisse named Essiac (her last name spelled backward), consisted of four main herbs:

  1. Burdock root (Arctium lappa)
  2. Sheep sorrel (Rumex acetosella)
  3. Slippery elm inner bark (Ulmus rubra)
  4. Turkey rhubarb root (Rheum palmatum)

These herbs were brewed into a tea and administered to patients seeking alternative treatments for various ailments, especially cancer.

Of course, each of the four main herbs is believed to offer specific health benefits, although scientific evidence supporting these claims is limited.

Potential benefits of this herbal blend:

  1. Burdock root (Arctium lappa):
    • Traditionally used in herbal medicine for its anti-inflammatory properties. [More]
    • Believed to support liver health and promote detoxification.
    • Some studies suggest it may have antioxidant properties.
  2. Sheep sorrel (Rumex acetosella):
    • Contains various vitamins and minerals, including vitamins A, B complex, C, D, E, and K, as well as minerals like calcium, magnesium, and potassium.
    • Often used in traditional medicine for its purported diuretic and antioxidant effects.
    • Advocates claim it may have immune-boosting properties.
  3. Slippery elm inner bark (Ulmus rubra):
    • Known for its mucilage content, which forms a gel-like substance when mixed with water. This mucilage is believed to soothe irritated tissues, including the digestive tract. [More]
    • Traditionally used to alleviate symptoms of conditions like sore throat, cough, and gastrointestinal issues.
    • Some proponents claim it may have anti-inflammatory effects.
  4. Turkey rhubarb root (Rheum palmatum):
    • Historically used in traditional medicine as a laxative and for digestive support.
    • Contains compounds like anthraquinones, which are believed to have laxative effects.
    • Advocates claim it may support detoxification and promote gastrointestinal health.

Together, these herbs are believed to work synergistically to provide various health benefits, including immune support, detoxification, and potential anti-cancer effects.

However, it’s important to note that much of the evidence supporting these claims is anecdotal, and more rigorous scientific research is needed to validate the purported benefits.

Essiac Tea Alleviates Symptoms

In this case, Caisse claimed that Essiac tea helped alleviate symptoms and improve quality of life for many of her patients.

However, despite its popularity and anecdotal evidence of effectiveness, scientific studies supporting the health claims of Essiac tea are limited. Some small-scale studies have been conducted, but the results have been inconclusive or conflicting.

Despite the lack of robust scientific evidence, Essiac tea continues to be used by some individuals as a complementary or alternative therapy.

It must be remembered that it’s important for individuals considering Essiac tea (or any alternative treatment) to consult with a healthcare professional, as it may interact with certain medications or conditions.

Essiac Tea Today

On the other hand, Essiac tea continues to be discussed in alternative medicine circles today.

Despite the limited scientific evidence supporting its efficacy, some proponents still advocate for its use as a complementary or alternative therapy for various health conditions, including cancer.

Additionally, the tea is often promoted as a natural remedy for detoxification, immune support, beyond cancer treatment support.

While Essiac tea may have a dedicated following in alternative medicine communities, mainstream medical professionals typically recommend sticking to evidence-based treatments for cancer and other serious health conditions.

Of Note:

Several herbs and plant-derived compounds have been studied for their potential anti-cancer properties.

While research is ongoing and the evidence varies, here are some herbs that have shown promise in preclinical studies or have been traditionally used for potential anti-cancer effects:

Green Tea (Camellia sinensis):

Green tea contains polyphenols, particularly catechins, which have antioxidant properties.

Epigallocatechin gallate (EGCG), a catechin in green tea, has been studied for its potential anti-cancer effects, including inhibiting tumor growth and metastasis.

Turmeric (Curcuma longa):

Turmeric contains curcumin, a compound with potent anti-inflammatory and antioxidant properties.

Studies suggest that curcumin may inhibit the growth of cancer cells. In addition, it may help prevent the spread of tumors by interfering with various cellular pathways.

Ginger (Zingiber officinale):

Ginger contains gingerol, a bioactive compound with antioxidant and anti-inflammatory properties.

Some studies have indicated that ginger extract may inhibit the growth of cancer cells and induce apoptosis (cell death) in various types of cancer.

Garlic (Allium sativum):

That tasty clove used in your cooking contains organosulfur compounds, including allicin, which has also been linked to potential anti-cancer effects.

Studies suggest that garlic may inhibit cancer cell growth, promote cancer cell death, and have anti-inflammatory effects.

Ginseng (Panax ginseng):

Traditional Chinese medicine often uses ginseng for its adaptogenic and immune-boosting properties.

Some studies suggest that ginsenosides, the active compounds in ginseng, may have anti-cancer effects by inhibiting tumor growth, angiogenesis (formation of new blood vessels), and metastasis.

Mushrooms (e.g., Reishi, Shiitake, Maitake):

Various mushrooms contain bioactive compounds such as polysaccharides, beta-glucans, and triterpenes, which have been studied for their potential anti-cancer effects.

Some research suggests that mushroom extracts may stimulate the immune system, inhibit tumor growth, and enhance the effects of chemotherapy and radiation therapy.

Cat’s Claw (Uncaria tomentosa):

Traditionally used in South American folk medicine for its anti-inflammatory and immune-stimulating properties.

Some studies suggest that cat’s claw extracts may have anti-cancer effects by modulating immune function and inhibiting tumor cell proliferation.


It’s important to note that while these herbs and compounds show promise in laboratory studies, more research is needed. This includes conducting clinical trials in humans to determine safety and efficacy as anti-cancer agents.

Additionally, herbal remedies should be used with caution and under the guidance of a healthcare professional. This is especially the case when used in conjunction with conventional cancer treatments.
