HelloPharmacist Scorecard of Rene's Tea by Oregon's Wild Harvest

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

Full disclosure
Ingredient Transparency · database check
Full

Every active ingredient lists its own amount on the label.

Why this rating?
  • The label discloses an exact amount for 4 of its 4 active ingredients.
  • No proprietary blends here — you can verify the dose of every single component.

Rene's Tea contains four active ingredients: Burdock (a root traditionally used in herbal medicine), Slippery Elm (an inner bark with mucilage content), Sheep Sorrel (an herb), and Chinese Rhubarb (the root used for its laxative properties). The product contains no inactive ingredients listed.

Does it work?

Not established
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
Not established

The graded evidence we hold for these ingredients covers different conditions than the ones this product is marketed for, so there's no established rating for its stated use.

Why this rating?
  • The label markets this product for: Herbal tea blend for digestive and respiratory wellness.
  • We looked for evidence on: Acne, Atopic dermatitis (eczema), Bronchitis, Common cold, Constipation, Cough — and 4 related terms.
  • The closest evidence on file: Burdock is rated "Insufficient Reliable Evidence To Rate" for Acne (Natural Medicines).
  • Also on file: Burdock is rated "Insufficient Reliable Evidence To Rate" for Common cold, Atopic dermatitis (eczema), Hepatitis.
  • Also on file: Rhubarb is rated "Insufficient Reliable Evidence To Rate" for Constipation.

The evidence for these ingredients is limited. Burdock, Slippery Elm, and Sheep Sorrel all carry insufficient reliable evidence to rate them for the conditions they're traditionally used for—including acne, cough, constipation, and other uses.

Chinese Rhubarb is rated as possibly effective for menopausal symptoms and pancreatitis, but evidence for other common uses like constipation is insufficient. If you're considering this tea for a specific health goal, talk with your pharmacist about what the evidence actually supports.

The evidence, ingredient by ingredient Burdock Slippery Elm Sorrel 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 human safety data are limited. It's generally well tolerated when consumed as food, though rare allergic reactions (including anaphylaxis and contact dermatitis) and one case of liver disease have been reported.

Slippery Elm is generally well tolerated for short-term use, though high-quality safety data are limited; contact dermatitis, urticaria, and allergic reactions to its pollen have been noted. Sheep Sorrel is generally safe in food amounts but contains oxalates, which in concentrated doses can raise kidney disease risk—one case of kidney inflammation was reported in a child who consumed wild sorrel.

Chinese Rhubarb root (not the stalk) can cause cramping, diarrhea, nausea, and vomiting; chronic use may deplete potassium and other electrolytes and damage the kidneys. Burdock, Sheep Sorrel, and Chinese Rhubarb should be avoided at medicinal doses during pregnancy.

Burdock and Rhubarb should also be avoided while breastfeeding; Sorrel in medicinal amounts and Slippery Elm in concentrated amounts should be avoided while nursing due to insufficient 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 Rene's Tea, double-check these medications with your pharmacist: blood thinners and antiplatelet drugs (warfarin, aspirin, clopidogrel); any oral medications (Slippery Elm may slow absorption); allergy medications like fexofenadine; heart drugs including digoxin; corticosteroids and diuretics; immunosuppressants like cyclosporine; stimulant laxatives; and any drugs toxic to the liver or kidneys. The worst-case interactions are with blood thinners (moderate severity) and potentially serious drugs like cyclosporine and digoxin.

Each ingredient & the kinds of drugs it affects

For each ingredient in Rene's Tea 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 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

Chinese 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
Chinese 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

Burdock1 drug type · 122 drugs

Anticoagulant/Antiplatelet Drugs

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

Rene's Tea by Oregon's Wild Harvest: Common Questions

Does Rene's Tea by Oregon's Wild Harvest interact with any medications?
Yes. Based on its ingredients, Rene's Tea 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?
Rene's Tea 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 this if I'm pregnant or breastfeeding?
At medicinal doses, Burdock, Sheep Sorrel, and Chinese Rhubarb should be avoided during pregnancy because safety data are lacking and they may affect the uterus. During breastfeeding, Burdock and Rhubarb should be avoided; Sorrel in medicinal amounts and concentrated Slippery Elm should also be avoided. Talk with your pharmacist or doctor for personalized advice.
Will this tea help with constipation?
Chinese Rhubarb does have laxative effects and is traditionally used for constipation, but the evidence rating for this use is insufficient. Slippery Elm and Burdock also lack sufficient reliable evidence for constipation. If constipation is your main concern, ask your pharmacist about options with stronger evidence.
What side effects might I notice?
The most common are gastrointestinal: cramping, diarrhea, nausea, and vomiting—mainly from the Rhubarb. Allergic reactions including contact dermatitis or anaphylaxis are rare but possible. Chronic or heavy use of Rhubarb can deplete potassium and other minerals and damage the kidneys.
Does this tea have any fillers or additives?
No inactive ingredients are listed for this product.
Is it safe to take this long-term?
Burdock and Slippery Elm are noted as likely safe for short-term use, but long-term safety data are limited. Rhubarb should not be used long-term as a laxative—chronic use can cause mineral loss and kidney damage. Talk with your pharmacist about how long it's safe to take this particular tea.
What is each ingredient in this tea supposed to do?
Burdock, Slippery Elm, and Sheep Sorrel are traditionally used for various health purposes, but the evidence for most of these uses is insufficient to rate. Chinese Rhubarb has some evidence (though still limited) for menopausal symptoms and pancreatitis, and is known for its laxative effect. If you're using this for a specific reason, check with your pharmacist about what evidence actually exists for that use.
