HelloPharmacist Scorecard of Sheep Sorrel Alcohol Free by Hawaii Pharm

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.

Sheep Sorrel Alcohol Free contains one active ingredient: Sheep Sorrel Herb Extract, Dry — a concentrated form of the plant traditionally used for various conditions. The liquid also contains glycerin and water as inactive ingredients to deliver the extract.

Sorrel is a plant in the buckwheat family, and the extract concentrates its compounds. Because this is labeled alcohol-free, the extract was prepared without ethanol, though lab studies on sorrel's effects have used ethanol versions.

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 data we hold doesn't establish that sorrel is effective for any condition. For bronchitis, breast cancer, and rhinosinusitis (sinus inflammation), the evidence is rated insufficient — meaning we don't have enough reliable studies to know whether it works or doesn't.

If you're considering this product for a specific health goal, your doctor or pharmacist can discuss what the current research actually supports and what alternatives might be better studied.

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.

Sorrel is generally well tolerated in food amounts, but the safety facts highlight two key concerns. First, sorrel is high in oxalates — compounds that, in large or concentrated doses, can build up in your body and potentially damage your kidneys.

A case report documents one child who developed kidney inflammation (tubulointerstitial nephritis) after consuming an unknown amount of wild sorrel. Second, some people allergic to weed pollen may react to sorrel pollen exposure, and up to 19% of people with weed allergies could have cross-sensitivity.

When used in combination with other herbs, sorrel has been reported to cause nausea and an unpleasant aftertaste. For pregnancy and breastfeeding, the safety data rates sorrel as possibly safe, but research on medicinal or concentrated amounts is sparse.

The safety notes advise avoiding concentrated supplements while breastfeeding. If you're pregnant or nursing and want to use this product, talk it over with your doctor or pharmacist so they can weigh the limited data and your individual situation.

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.

Check before combining this product with blood thinners (anticoagulants and antiplatelet drugs) — sorrel may add to their effects and raise bleeding risk. Also confirm it's safe with fexofenadine (Allegra) and other OATP substrates, a broad drug family that includes some heart, cancer, and allergy medicines — sorrel may reduce how well your body absorbs them.

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.

This product is a single-ingredient sorrel extract with documented interactions affecting a large number of medications — particularly blood thinners and allergy/heart medicines. If you take any prescription drugs, especially anticoagulants or antihistamines, you need to check with your doctor or pharmacist before starting it.

The evidence for sorrel's effectiveness isn't established in our data, and the high oxalate content is a safety concern at higher doses.

Sheep Sorrel Herb Extract, Dry3 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 Alcohol Free by Hawaii Pharm: Common Questions

Does Sheep Sorrel Alcohol Free by Hawaii Pharm interact with any medications?
Yes. Based on its ingredients, Sheep Sorrel Alcohol Free 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 Alcohol Free 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.
Does this product work for bronchitis, breast cancer, or sinus problems?
The evidence we hold doesn't establish that sorrel is effective for any of these conditions. The data rates the evidence as insufficient — we simply don't have enough reliable studies to say whether it helps or doesn't. Ask your doctor or pharmacist what treatments have stronger evidence for what you're dealing with.
Is sorrel safe if I'm pregnant or breastfeeding?
Sorrel is rated possibly safe in pregnancy and lactation, but research on medicinal or concentrated amounts is limited. The safety data specifically advises avoiding concentrated supplements while breastfeeding. Talk with your doctor or pharmacist about whether this product is right for you during this time — they can discuss the limited data with your specific situation in mind.
What are the side effects I should know about?
The main concerns are kidney-related: sorrel is high in oxalates, which can accumulate and damage your kidneys at large or concentrated doses. One child developed kidney inflammation after consuming wild sorrel. Some people allergic to weed pollen may react to sorrel, and nausea and aftertaste have been reported when it's combined with other herbs. If you have a history of kidney problems, mention this product to your doctor or pharmacist first.
Why does this product interact with so many medications?
Sorrel blocks a protein (OATP) in your gut and liver that normally absorbs many different types of medications into your body. When sorrel blocks this protein, your body absorbs those drugs less effectively — making them potentially less powerful. That's why it affects such a large range of prescriptions across different categories.
Can I take this if I'm on Allegra (fexofenadine)?
Not without checking first. Lab studies show sorrel inhibits the protein responsible for absorbing fexofenadine, which could make the allergy medication less effective. Talk with your doctor or pharmacist before starting this product if you use Allegra or any other antihistamine.
Is this product safe to combine with blood thinners?
No — not without discussing it with your doctor first. Sorrel has a moderate-severity interaction with blood thinners and can theoretically add to their effects, raising your bleeding risk. If you take warfarin, apixaban, aspirin, or any other blood thinner, mention this product to your prescriber before you use it.
