HelloPharmacist Scorecard of Sheep Sorrel by Herbal Terra

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 1 of its 1 active ingredient.
  • No proprietary blends here — you can verify the dose of every single component.

This product contains one active ingredient: certified organic Sheep Sorrel (Rumex acetosella) as a dried herb liquid extract. Sheep sorrel is a plant used in herbal medicine.

The inactive ingredient is menstruum, a liquid base used to extract and deliver the herb.

Does it work?

Couldn't assess
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 assessable

This is a single-ingredient Sorrel product and its label doesn't state a use — see Sorrel's own graded uses on its monograph.

Why this rating?
  • We looked at the product name, claims, and label statements and couldn't find a stated purpose to grade.

The evidence for sheep sorrel isn't established in our data. It's listed for uses including bronchitis, breast cancer support, and rhinosinusitis (sinus inflammation), but each of these ratings is insufficient reliable evidence to rate — meaning we don't have solid proof that it works for these purposes.

If you're considering it for a specific health goal, that's a good conversation to have with your pharmacist or doctor.

The evidence, ingredient by ingredient Sorrel

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 1 of the 1 matched ingredient.
  • Pregnancy & breastfeeding safety ratings cover 1 of 1.
  • General safety write-ups exist for 1 of 1.
  • Remember: this measures how much safety information exists. Thin data is not the same as being safe.

Sheep sorrel is generally well tolerated in food amounts, but there are concerns with larger or concentrated doses. The plant is high in oxalates, which can accumulate in the body and potentially cause kidney problems, especially with long-term use.

A case of kidney inflammation has been reported in a child who consumed wild sorrel. You may also experience gastrointestinal side effects like nausea or an unpleasant aftertaste.

If you're sensitive to weed pollen, you may react to sorrel pollen as well.

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?
  • 1 of the 1 matched ingredient can interact with medications — Sorrel.
  • The most serious interaction on file is rated Moderate.
  • Some involve high-stakes drug classes: anticoagulant / antiplatelet drugs.
  • For scale: 169 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.

Double-check this product if you take blood thinners or antiplatelet drugs (such as warfarin or aspirin) — sorrel may add to their effects. Also flag it if you take OATP substrate medications or fexofenadine (Allegra), as sorrel might reduce how well your body absorbs them.

Your pharmacist can tell you if your medications are affected.

The bottom line

Scorecard at a glanceFully disclosed formula with no assessable stated purpose. Moderate medication interactions have been identified, and safety information is well characterized.

Sheep sorrel is used in herbal medicine for several conditions, but the evidence supporting those uses isn't solid. The bigger consideration here is its interactions with blood thinners, antiplatelet drugs, and certain other medications — and its oxalate content, which can be an issue with concentrated doses.

If you take any prescription medications, check them against this product before you start, and talk with your pharmacist about whether it's right for you.

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.

Sheep Sorrel by Herbal Terra: Common Questions

Does Sheep Sorrel by Herbal Terra interact with any medications?
Yes. Based on its ingredients, Sheep Sorrel has a known interaction with 169 medications. Use the checker to see how it interacts with a specific drug.
How can one product interact with so many drugs?
Sheep Sorrel contains a single active ingredient, and that one ingredient can interact with many different medications on its own. We check it against each medication and show the mechanism 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 sheep sorrel safe to use while breastfeeding?
The safety data on medicinal amounts of sorrel during breastfeeding is limited. The facts advise against concentrated supplements while breastfeeding. Talk with your doctor or pharmacist about whether this product is right for you in that situation.
Can sheep sorrel help with bronchitis?
Sorrel is used traditionally for bronchitis, but our data shows insufficient reliable evidence to confirm it actually works. If you're dealing with bronchitis, your doctor can advise you on treatments with proven benefit.
What are the side effects I might notice?
The most common reported side effect when sorrel is combined with other herbs is gastrointestinal upset — nausea and an unpleasant aftertaste. If you're allergic to weed pollen, sorrel pollen exposure may trigger allergic symptoms. With larger doses over time, the high oxalate content can theoretically cause kidney concerns.
Is sheep sorrel safe during pregnancy?
The pregnancy safety rating for sorrel is possibly safe, but the data is limited. Any use during pregnancy should be discussed with your doctor or pharmacist, especially since concentrated medicinal amounts haven't been well studied.
What is the 'menstruum' listed in the ingredients?
Menstruum is the liquid base — typically an alcohol and water mix — that's used to extract the active plant compounds from the dried sorrel and deliver it in liquid form. It's an inactive ingredient.
