HelloPharmacist Scorecard of Esiak 450 mg by Vitabase

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 (Herb/Botanical)” is a proprietary blend — the label gives one combined amount (450 mg) without saying how much of each component you get.

Esiak contains 4 active herbal ingredients: burdock root, sheep sorrel (also called sorrel), slippery elm inner bark, and turkey rhubarb root. These are combined in a proprietary blend, meaning the exact proportion of each isn't disclosed on the label.

The capsule also contains gelatin and magnesium stearate as inactive ingredients (a binder and flow agent).

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 these ingredients is limited. For burdock, there's insufficient reliable evidence to rate its effectiveness for acne, aging skin, breast cancer, common cold, or eczema.

Sheep sorrel has insufficient evidence for bronchitis, breast cancer, or sinus inflammation. Slippery elm's effectiveness for cancer, constipation, cough, inflammatory bowel disease, or diarrhea is likewise not established in the data we hold.

Turkey rhubarb shows possibly effective evidence for pancreatitis and menopausal symptoms, but insufficient evidence for appendicitis, nasopharyngeal cancer, fatty liver disease, or constipation. Overall, this product's effectiveness for any specific condition isn't well supported by reliable research.

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, but human safety data are limited. Allergic reactions including contact dermatitis and anaphylaxis are rare but reported; one case of drug-induced liver disease was documented after prolonged use in a tea blend, though it's unclear if burdock alone was responsible.

Sheep sorrel is generally safe in food amounts but contains oxalates — high or concentrated doses can stress your kidneys, and one case of kidney inflammation has been reported. Slippery elm is generally well tolerated for short-term use with limited safety data; contact dermatitis and urticaria (hives) can occur.

Turkey rhubarb root used as a laxative can cause cramps and shouldn't be used long-term; chronic overuse may deplete potassium and damage your kidneys, and rare anaphylaxis has been reported. Burdock and turkey rhubarb should be avoided during pregnancy due to lack of safety data and possible effects on the uterus and bowels.

Sheep sorrel is rated possibly safe in pregnancy, but slippery elm carries caution from some sources. During breastfeeding, there isn't enough data for burdock, slippery elm, or turkey rhubarb (whose laxative compounds may pass into milk), so caution is advised; sheep sorrel in food amounts is likely fine, but medicinal amounts lack safety data.

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 Esiak, check with your doctor or pharmacist if you take any of these: blood thinners or antiplatelet drugs (like warfarin, aspirin, or clopidogrel) — burdock and sheep sorrel may increase bleeding risk; heart medications like digoxin — rhubarb may worsen potassium loss; diuretics or water pills — rhubarb can compound potassium depletion; corticosteroids — rhubarb increases potassium loss; cyclosporine — rhubarb may lower its levels; drugs transported by OATP proteins or fexofenadine (Allegra) — sheep sorrel may reduce their absorption; or any drug that stresses your kidneys or liver — rhubarb's anthraquinones carry theoretical risk. Moderate severity applies to all documented interactions.

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.

Esiak is an herbal blend with long historical use, but the scientific evidence for its effectiveness is thin, and it carries notable interaction risks — especially with blood thinners, heart drugs, diuretics, and medications that depend on liver or kidney function. If you take any prescription medications, especially anticoagulants, corticosteroids, or drugs affecting your kidney or liver, check with your doctor or pharmacist before starting this product.

Slippery Elm1 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 full monograph & interactions

Turkey Rhubarb8 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 full monograph & interactions

Sheep Sorrel3 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
Sheep Sorrel full monograph & interactions

Burdock1 drug type · 122 drugs

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.

Esiak 450 mg by Vitabase: Common Questions

Does Esiak 450 mg by Vitabase interact with any medications?
Yes. Based on its ingredients, Esiak 450 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?
Esiak 450 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.
Can I take Esiak if I'm on warfarin or another blood thinner?
Not without checking first. Turkey rhubarb in this blend can theoretically increase bleeding risk with warfarin by making diarrhea worse and raising your INR. Talk with your doctor or pharmacist about whether it's safe for you — they know your dose and your other medications.
What's a proprietary blend, and why don't I see the exact amounts of each herb?
A proprietary blend groups ingredients under a single total weight but keeps the individual amounts secret — it's a labeling choice manufacturers make. In this case, you're getting burdock, sheep sorrel, slippery elm, and turkey rhubarb, but not the exact proportion of each one.
Is this product safe during pregnancy?
Burdock and turkey rhubarb should be avoided during pregnancy because they may affect your uterus and bowels; the safety data just aren't there. Sheep sorrel is rated possibly safe, but slippery elm has some caution from sources. Talk with your doctor or midwife before taking it.
Can slippery elm interfere with my other medications?
Yes, theoretically. The mucilage in slippery elm may slow how fast your body absorbs oral medications, potentially lowering their levels. It's a Moderate interaction risk with oral drugs generally, so it's worth discussing with your pharmacist if you're on anything you depend on.
What are the most common side effects I might experience?
Turkey rhubarb is most likely to cause cramping, diarrhea, nausea, or gastrointestinal discomfort. Burdock and sheep sorrel can trigger allergic reactions in sensitive people — contact dermatitis or, rarely, anaphylaxis. If you have kidney problems, sorrel's oxalate content is a concern; high doses have caused kidney inflammation in rare cases.
Can I take Esiak if I'm on a diuretic (water pill)?
Check with your doctor first. Turkey rhubarb's laxative effects can worsen potassium loss, and combining it with a diuretic increases that risk. Your doctor can assess whether the combination is safe for you and whether you need blood work to monitor your potassium.
