HelloPharmacist Scorecard of Essiac Tonic by Herbs Etc.
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.
What’s inside
Low disclosure
Essiac Tonic contains 4 active ingredients in a proprietary blend: slippery elm, burdock, sheep sorrel (also called sorrel), and Chinese rhubarb. Slippery elm is traditionally used for digestive and respiratory comfort, burdock for skin health, sorrel for respiratory support, and rhubarb as a laxative and for other uses.
The product is filled in a softgel capsule made with extra virgin olive oil, sunflower lecithin, beeswax, and a softgel shell.
Does it work?
Couldn't assess
The evidence for these ingredients is limited. Slippery elm, burdock, and sorrel all have insufficient reliable evidence to support their use for any condition in our data—including cancer, constipation, cough, inflammatory bowel disease, diarrhea, acne, skin aging, breast cancer, common cold, eczema, bronchitis, and sinus inflammation.
Rhubarb shows possibly effective ratings for pancreatitis and menopausal symptoms, but evidence for constipation and other uses is insufficient. None of these ingredients have strong proof of benefit for the conditions often associated with Essiac products.
How safe is it?
Well-documented data
Slippery elm is generally well tolerated for short-term use, but long-term safety data are limited; some sources caution against pregnancy use, and breastfeeding safety is not well studied. The pollen can trigger allergies, and contact dermatitis or hives have been reported after exposure.
Burdock is likely safe as food and for short-term use in healthy adults, though human data are sparse. Serious allergic reactions including anaphylaxis are rare.
One case of liver injury has been reported, though it's unclear whether burdock alone was responsible. Sorrel is generally safe in food amounts but contains high oxalate levels; concentrated doses can raise kidney stone risk and rare kidney damage has occurred.
Medicinal use in pregnancy and breastfeeding is not well studied. Rhubarb root can cause cramping and should not be used long-term; medicinal amounts may stimulate the uterus, so pregnancy use is not advised, and laxative compounds may pass into breast milk during nursing.
Chronic overuse risks electrolyte loss, dehydration, and kidney damage.
Meds to double-check
Moderate interaction found
Before taking Essiac Tonic, check with your doctor or pharmacist if you take warfarin (Coumadin) or other blood thinners (anticoagulants or antiplatelets), digoxin (Lanoxin), cyclosporine (Neoral, Sandimmune), corticosteroids, diuretics (water pills), stimulant laxatives, fexofenadine (Allegra), or any drugs that can harm the kidneys or liver. Rhubarb's laxative action and effects on potassium and kidney function pose the broadest concerns.
The bottom line
Scorecard at a glanceFormula with limited ingredient disclosure with no assessable stated purpose. Moderate medication interactions have been identified, and safety information is well characterized.
Essiac Tonic is marketed for cancer and immune support, but the evidence for its ingredients' effectiveness in those areas is not established in the data we hold. More importantly, if you take warfarin, digoxin, cyclosporine, corticosteroids, diuretics, blood thinners, fexofenadine, or nephrotoxic or hepatotoxic drugs, this product carries documented Moderate-severity risks.
Before starting Essiac Tonic, talk with your own doctor or pharmacist about whether it's right for you and whether it's safe to combine with your medications.

Essiac Tonic by Herbs Etc. Drug Interactions
HelloPharmacist Interaction Report
Essiac Tonic by Herbs Etc. does interact with medications, primarily through its burdock, sheep sorrel, and Chinese rhubarb content.
The most serious interactions are Moderate in severity. Rhubarb poses several concerns: it may increase bleeding risk with warfarin (Coumadin), raise the risk of heart toxicity with digoxin (Lanoxin), reduce cyclosporine (Neoral, Sandimmune) effectiveness, and compound potassium loss when paired with corticosteroids, diuretics, or digoxin.
It may also raise kidney or liver damage risk when taken with nephrotoxic or hepatotoxic drugs, and increase fluid loss when combined with other stimulant laxatives.
Read the full breakdown — every affected drug type, severity by severity
Burdock and sheep sorrel both carry Moderate interactions with blood thinners (anticoagulant or antiplatelet drugs), theoretically raising bleeding risk. Sheep sorrel also may reduce the effectiveness of fexofenadine (Allegra) and other drugs transported by OATP proteins.
Slippery elm may slow the absorption and reduce blood levels of oral drugs generally.

For each ingredient in Essiac Tonic with known interactions, here are the types of medications they can affect. Open any type for the detail — or search your exact drug in the checker above.
Slippery Elm
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.
Chinese (a.k.a. Turkey) Rhubarb
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.
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.
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.
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.
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.
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.
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.
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.
Sheep Sorrel
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.
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).
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.
Burdock
Anticoagulant/Antiplatelet Drugs
Theoretically, taking burdock with anticoagulant or antiplatelet drugs might increase the risk of bleeding.
In vitro research shows that lignans from burdock reduce rabbit platelet aggregation by inhibiting platelet activating factor. This interaction has not been reported in humans.
