HelloPharmacist Scorecard of Essiac Tea 1350 mg by NusaPure

Our pharmacy team’s full take, with four database checks built into the cards below — a summary of what is known, not a grade of the product itself.

From our pharmacy team — supplement deep dive

Generated from HelloPharmacist’s pharmacist-curated databases and editorial rules · Last generated Jul 30, 2026

What’s inside

Low disclosure
Ingredient Transparency · database check
Low

Most active ingredients don't disclose an individual amount — you can't tell how much of each you're getting.

Why this rating?
  • The label discloses an exact amount for 0 of its 4 active ingredients.
  • “Proprietary Blend” is a proprietary blend — the label gives one combined amount (1,350 mg) without saying how much of each component you get.

Essiac Tea contains 4 active ingredients in a proprietary blend: burdock root extract, sheep sorrel leaf extract, slippery elm bark extract, and turkey rhubarb root extract. The product also contains cellulose, rice flour, and silica as inactive ingredients (binders and capsule material).

Burdock root has a long history in herbal practice and is used for skin and general wellness support. Sheep sorrel, slippery elm, and turkey rhubarb are also traditional botanical ingredients, with rhubarb traditionally used for digestive support.

Does it work?

Moderate evidence
Evidence for Intended Use · database check
By FDA rules, dietary supplements can’t claim to treat, cure, or prevent disease — so labels speak in careful marketing language. We discern each product’s intended use from its name, label claims, and label statements, then grade the clinical evidence for that use. How these ratings are computed

This product doesn't appear to be marketed for a specific use, so we graded its ingredients' overall clinical evidence instead.

Moderate

Some clinical evidence supports its ingredients for:

Why this rating?
  • We looked at the product name, claims, and label statements and couldn't find a stated purpose to grade.
  • Since the label doesn't commit to one use, we graded the ingredients' overall clinical evidence instead.
  • On file: Menopausal symptoms — rated "Possibly Effective" (Rhubarb) (Natural Medicines).
  • On file: Pancreatitis — rated "Possibly Effective" (Rhubarb) (Natural Medicines).

The evidence for Essiac Tea's ingredients is limited. Burdock shows insufficient reliable evidence for acne, aging skin, breast cancer, common cold, and eczema.

Sheep sorrel is similarly unproven for bronchitis, breast cancer, and rhinosinusitis. Slippery elm lacks sufficient evidence for cancer, constipation, cough, inflammatory bowel disease, and diarrhea.

Turkey rhubarb is rated possibly effective for menopausal symptoms and pancreatitis, but insufficient evidence supports it for appendicitis, nasopharyngeal cancer, nonalcoholic fatty liver disease, and constipation. Overall, the product's effectiveness for any specific health claim is not well established in the data we hold.

The evidence, ingredient by ingredient Burdock Sorrel Slippery Elm Rhubarb

How safe is it?

Well-documented data
Safety Information · database check
Well characterized

Adverse-effect, pregnancy, and general safety data are on file for most of these ingredients.

Why this rating?
  • We hold adverse-effect (side-effect) data for 4 of the 4 matched ingredients.
  • Pregnancy & breastfeeding safety ratings cover 4 of 4.
  • General safety write-ups exist for 4 of 4.
  • Remember: this measures how much safety information exists. Thin data is not the same as being safe.

Burdock is likely safe as a food and for short-term use in healthy adults, though serious allergic reactions including anaphylaxis are rare, and a case of drug-induced liver disease has been reported with herbal products containing burdock. Contact dermatitis can occur, especially after prolonged use.

Avoid medicinal amounts during pregnancy and while breastfeeding due to lack of safety data. Sheep sorrel is generally safe in food amounts but has high oxalate content — large or concentrated doses may pose kidney concerns, and a case of kidney inflammation was reported in a child who consumed wild sorrel.

Avoid medicinal amounts while pregnant or breastfeeding. Slippery elm is generally well tolerated for short-term use but may cause contact dermatitis or allergic reactions.

Turkey rhubarb root (not the stalk) can cause cramping, diarrhea, and electrolyte loss with chronic use; avoid medicinal amounts during pregnancy and breastfeeding. All four ingredients carry rare allergic risks.

Meds to double-check

Moderate interaction found
Known Interaction Concern · database check
Moderate identified

The most serious documented interaction for these ingredients is Moderate. Check your medications for a personalized result.

Why this rating?
  • 4 of the 4 matched ingredients can interact with medications — Burdock, Rhubarb, Sorrel, Slippery Elm.
  • The most serious interaction on file is rated Moderate.
  • Some involve high-stakes drug classes: anticoagulant / antiplatelet drugs; immunosuppressants / transplant drugs; heart-rhythm medications.
  • For scale: 2,131 individual medications appear in the full list. A big number alone doesn't make a product dangerous — what matters is whether YOUR medication is on it, so run yours through the interaction checker on this page.

Before taking Essiac Tea, double-check these medication types with your doctor or pharmacist: blood thinners and antiplatelet drugs (moderate risk of increased bleeding), diuretics and corticosteroids (moderate risk of potassium loss), warfarin, digoxin, cyclosporine, and any nephrotoxic or hepatotoxic medications (moderate risks of toxicity or reduced effectiveness). Slippery elm may slow absorption of any oral drug taken at the same time, and sorrel may reduce effectiveness of fexofenadine and other OATP-dependent drugs.

The bottom line

Scorecard at a glanceFormula with limited ingredient disclosure with some supporting evidence behind its ingredients' uses. Moderate medication interactions have been identified, and safety information is well characterized.

Essiac Tea is a four-ingredient herbal blend with a long traditional history, but scientific evidence for its effectiveness is insufficient for most claimed uses. The main concern is medication interactions — especially with blood thinners, heart medications, water pills, and drugs dependent on normal absorption.

If you take any prescription medications, check your specific drugs with the tool on this page, and talk with your doctor or pharmacist before starting.

Slippery Elm Bark Extract1 drug type · 2,022 drugs

Oral Drugs

Theoretically, slippery elm may slow the absorption and reduce serum levels of oral drugs.
Slippery elm inner bark contains mucilage, which may interfere with the absorption of orally administered drugs.

Likelihood Possible Evidence D
Slippery Elm Bark Extract full monograph & interactions

Turkey Rhubarb Root Extract8 drug types · 658 drugs

Corticosteroids

Theoretically, frequent and high doses of rhubarb might increase the risk of hypokalemia when taken with corticosteroids.
Rhubarb has stimulant laxative effects. Overuse of rhubarb might compound corticosteroid-induced potassium loss.

Likelihood Possible Evidence D
Cyclosporine (Neoral, Sandimmune)

Theoretically, taking rhubarb with cyclosporine might reduce cyclosporine levels.
Animal research shows that co-administration of rhubarb decoction 0.25 or 1 gram/kg with cyclosporine 2.5 mg/kg, decreases cyclosporine maximum plasma concentration and overall exposure levels when compared with taking cyclosporine alone. The authors theorize that rhubarb might reduce cyclosporine bioavailability by inducing of P-glycoprotein and/or cytochrome P450 3A4. However, since rhubarb was administered as a single oral dose and enzyme induction usually occurs after multiple doses, it is possible that cyclosporine absorption was actually reduced via rhubarb's stimulant laxative effects. Also, the composition of the rhubarb decoction was not described.

Likelihood Possible Evidence D
Digoxin (Lanoxin)

Theoretically, overuse of rhubarb might increase the risk of adverse effects when taken with digoxin.
Rhubarb has stimulant laxative effects. Overuse of rhubarb might cause potassium depletion, increasing the risk of digoxin toxicity.

Likelihood Possible Evidence D
Diuretic Drugs

Theoretically, frequent and high doses of rhubarb might increase the risk of hypokalemia.
Rhubarb has stimulant laxative effects. Overuse of rhubarb might cause potassium depletion and compound diuretic-induced potassium loss.

Likelihood Possible Evidence D
Hepatotoxic Drugs

Theoretically, concomitant use of rhubarb with potentially hepatotoxic drugs might increase the risk of developing liver damage.
Some animal research suggests that anthraquinones in rhubarb might have hepatotoxic effects. Also, rhubarb use has been linked to at least 24 cases of liver injury, although details on the dose of rhubarb and duration of use in these cases is unclear.

Likelihood Possible Evidence D
Nephrotoxic Drugs

Theoretically, long-term use of anthraquinones from rhubarb might increase the risk of nephrotoxicity when used with nephrotoxic drugs.
The anthraquinone constituents of rhubarb have been shown to induce nephrotoxicity in animal research. Additionally, in a case report, a 23-year old female presented with kidney failure after taking 6 tablets of a proprietary slimming agent (found to contain the anthraquinones emodin and aloe-emodin from rhubarb) daily for 6 weeks and then adding diclofenac 25 mg 4 times daily for 2 days. The authors postulate that the anthraquinone constituents of rhubarb contributed to the renal dysfunction, and the addition of diclofenac, a nephrotoxic drug, led to renal failure. Until more is known, advise patients to avoid taking rhubarb if they are taking other potentially nephrotoxic drugs.

Likelihood Possible Evidence D
Stimulant Laxatives

Theoretically, rhubarb might increase the risk for fluid and electrolyte loss when taken with other stimulant laxatives.
Rhubarb has stimulant laxative effects. Concomitant use with stimulant laxatives might compound fluid and electrolyte loss.

Likelihood Possible Evidence D
Warfarin (Coumadin)

Theoretically, excessive use of rhubarb might increase the risk of bleeding when taken with warfarin.
Rhubarb has stimulant laxative effects and can cause diarrhea. Diarrhea can increase the effects of warfarin, increase international normalized ratio (INR), and increase the risk of bleeding. Advise patients who take warfarin not to take excessive amounts of rhubarb.

Likelihood Possible Evidence D
Turkey Rhubarb Root Extract full monograph & interactions

Sheep Sorrel leaf extract3 drug types · 169 drugs

Anticoagulant/Antiplatelet Drugs

Theoretically, sorrel might cause additive effects and side effects when used with anticoagulant or antiplatelet drugs.
In vitro, sorrel has been shown to inhibit platelet aggregation. However, this effect has not been reported in humans.

Likelihood Possible Evidence D
Fexofenadine (Allegra)

Sorrel might reduce the effectiveness of fexofenadine by reducing its absorption from the gut.
In vitro research shows that an ethanol extract of sorrel inhibits organic anion-transporting polypeptide 1A2 (OATP1A2), which transports fexofenadine from the intestine into cells. In rats, concomitant administration of sorrel extract with fexofenadine reduces oral absorption of fexofenadine and the area under the plasma concentration-time curve (AUC).

Likelihood Likely Evidence D
Organic Anion-Transporting Polypeptide Substrates (Oatp)

Sorrel might reduce the effectiveness of OATP substrates by reducing their absorption from the gut.
In vitro research shows that sorrel inhibits OATP1A2. Theoretically it may inhibit other OATPs. The OATPs are expressed in the small intestine and liver and transport drugs into cells. Inhibition of OATP may reduce the bioavailability of oral drugs that are substrates of OATP.

Likelihood Possible Evidence D

Burdock Root Extract1 drug type · 122 drugs

Anticoagulant/Antiplatelet Drugs

Theoretically, taking burdock with anticoagulant or antiplatelet drugs might increase the risk of bleeding.

Essiac Tea 1350 mg by NusaPure: Common Questions

Does Essiac Tea 1350 mg by NusaPure interact with any medications?
Yes. Based on its ingredients, Essiac Tea 1350 mg has a known interaction with 2,130 medications. Use the checker to see how it interacts with a specific drug.
How can one product interact with so many drugs?
Essiac Tea 1350 mg contains 4 active ingredients, and an interaction can come from any of them. We check every ingredient, combine the results into one list per medication, and show which ingredient and mechanism is responsible.
Where does this information come from?
The product label data comes from the NIH Dietary Supplement Label Database (DSLD); the interaction data is built on the Natural Medicines database and reviewed by HelloPharmacist pharmacists.
Is it safe to take Essiac Tea during pregnancy?
No. Burdock and turkey rhubarb should be avoided in medicinal amounts during pregnancy due to lack of safety data and possible effects on the uterus. Sorrel is rated possibly safe in food amounts, but medicinal amounts haven't been proven safe, and slippery elm has cautions listed. Talk with your doctor or pharmacist before taking any supplement while pregnant.
Can I take Essiac Tea while breastfeeding?
The safety data are limited. Avoid medicinal amounts of burdock and turkey rhubarb while breastfeeding — laxative compounds from rhubarb may pass into breast milk. Sorrel and slippery elm also have too little safety information for breastfeeding use. Discuss this with your doctor or pharmacist for personalized advice.
What are the most common side effects?
From turkey rhubarb, the most common are cramps, diarrhea, gastrointestinal discomfort, nausea, and vomiting. Burdock and sorrel are generally well tolerated when consumed as food. All ingredients carry a small risk of allergic reactions, including contact dermatitis.
Will Essiac Tea slow down my other medications?
Possibly. Slippery elm's mucilage may interfere with the absorption of oral drugs taken at the same time. Sorrel may reduce the absorption of certain medications, including the antihistamine fexofenadine. Space your medications and supplements apart, and ask your pharmacist about the best timing for your specific drugs.
Is there enough evidence that Essiac Tea actually works?
Not yet. Most of the ingredients lack sufficient reliable evidence to support their effectiveness for the conditions they're traditionally used for. Turkey rhubarb is rated possibly effective for menopausal symptoms and pancreatitis, but the other three ingredients and most of rhubarb's claimed uses remain unproven in the research we hold.
