HelloPharmacist Scorecard of Sheep Sorrel by TerraVita

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

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: Sheep Sorrel Glycerite Liquid Extract. The glycerin listed is an inactive ingredient — it's the base that holds the extract.

Sheep sorrel is a leafy plant, and here it's been concentrated into a liquid form for easy dosing.

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 the data we hold. It's been studied for bronchitis, breast cancer, and rhinosinusitis (sinus inflammation), but none of those uses have sufficient reliable evidence to rate.

If you're thinking about this for a specific health concern, 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 the small amounts you'd get from food, but medicinal or concentrated doses — like this supplement — haven't been proven safe. The main concern is oxalate content.

Oxalates are compounds in sorrel that, in large amounts, can build up in your body and potentially damage your kidneys. There's also a risk of allergic reactions (especially if you're sensitive to weed pollen) and gastrointestinal side effects like nausea and an unpleasant aftertaste when used with other herbs.

If you're pregnant or breastfeeding, there isn't enough safety data for concentrated supplements, so talk with your pharmacist or doctor first.

Side effects, ingredient by ingredient Sorrel

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.

Before you take this, check whether you use blood thinners or antiplatelet drugs (like warfarin, aspirin, or clopidogrel) — sorrel may increase their effect. Also check if you take fexofenadine (Allegra) or other drugs that rely on OATP transporters to be absorbed, since sorrel may reduce how well they work.

The interaction tool on this page can help you verify your specific medications.

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 may interest you if you're exploring traditional herbal options, but it's not one to start without checking your medications first — especially if you take blood thinners or allergy medicines. The safety data for medicinal use is thin, and the kidney risk from oxalates is real.

Talk to your pharmacist before adding this to your routine.

Sheep Sorrel Glycerite Liquid 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.

Sheep Sorrel by TerraVita: Common Questions

Does Sheep Sorrel by TerraVita 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 if I'm pregnant or breastfeeding?
There isn't enough safety data for medicinal or concentrated amounts during pregnancy or breastfeeding. Food amounts are likely fine, but this supplement is more concentrated than that. Talk with your pharmacist or doctor to see what's right for you.
What's inside this liquid?
It's sheep sorrel extract mixed with glycerin, which is a thickening agent. There are no other active ingredients.
Does sheep sorrel actually work for bronchitis or the other things it's marketed for?
The evidence isn't reliable enough to say. It's been studied for bronchitis, breast cancer, and sinus issues, but none of those uses have solid proof yet.
What side effects might I notice?
Some people report nausea and an unpleasant aftertaste, especially when sorrel is combined with other herbs. If you're allergic to weed pollen, you may have an allergic reaction. With regular or concentrated use, there's a risk of kidney issues from the oxalate content.
Why can't I just take this with my blood thinner?
Sorrel may slow down blood clotting in the same way your medication does, which could increase your bleeding risk. That's why you need to check with your pharmacist or doctor first if you're on a blood thinner.
