HelloPharmacist Scorecard of Stinging Nettle 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.

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: certified organic Stinging Nettle (Urtica dioica) dried leaf liquid extract. It's a single-ingredient supplement with no other actives.

The inactive ingredient listed is menstruum, which is the liquid solvent used to extract the nettle's compounds.

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 Stinging Nettle's overall clinical evidence instead.

Moderate

Some clinical evidence supports Stinging Nettle 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 ingredient's overall clinical evidence instead.
  • On file: Diabetes — rated "Possibly Effective" (Natural Medicines).

Stinging nettle is possibly effective for diabetes based on research showing it may help decrease blood glucose levels. For other uses — hay fever, anemia, asthma, benign prostatic hyperplasia (enlarged prostate), and gingivitis — the evidence we hold is insufficient to rate whether it works.

That doesn't mean it's ineffective; it means the research isn't solid enough yet to say one way or the other.

The evidence, ingredient by ingredient Stinging Nettle

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.

Stinging nettle is generally well tolerated in adults when used as directed, though quality and safety evidence vary by product. The most common side effects are constipation or diarrhea taken orally.

Rare case reports describe liver injury (idiosyncratic drug-induced liver disease) in people taking herbal products containing stinging nettle along with other ingredients, though causation wasn't firmly established. If you touch the raw fresh plant, you may get a localized sting, rash, or itching that typically fades on its own but can last over 12 hours.

Stinging nettle is best avoided during pregnancy due to traditional concerns about effects on the uterus and insufficient safety data. Safety during breastfeeding has not been established, so talk with your doctor or pharmacist before using it if you're nursing.

The bottom line

Scorecard at a glanceFully disclosed formula with some supporting evidence behind its ingredients' uses. Moderate medication interactions have been identified, and safety information is well characterized.

Stinging nettle is worth considering if you're looking into diabetes support and want to explore herbal options — but only after you've checked it against any diabetes, blood thinner, blood pressure, or mood-stabilizing medications you take. If you take lithium, warfarin, a diuretic, or a diabetes drug, have a pharmacist run your full medication list against this product first.

Pregnancy and breastfeeding are contraindications — talk with your doctor if either applies.

Antidiabetes Drugs

Theoretically, stinging nettle might have additive effects with antidiabetes drugs.
Clinical research shows that stinging nettle might decrease blood glucose levels in patients with diabetes.

Likelihood Possible Evidence B
Diuretic Drugs

Theoretically, combining stinging nettle with diuretic drugs may have additive effects.
Animal research suggests that the above ground parts and roots of stinging nettle may have a diuretic effect.

Likelihood Possible Evidence D
Lithium

Theoretically, stinging nettle might reduce excretion and increase levels of lithium.
Animal research suggests that stinging nettle has diuretic and natriuretic properties, which could alter the excretion of lithium. The dose of lithium might need to be decreased.

Likelihood Possible Evidence D
Warfarin (Coumadin)

There is some concern that stinging nettle might decrease the effects of anticoagulant drugs such as warfarin.
Stinging nettle contains a significant amount of vitamin K. When taken in large quantities, this might interfere with the activity of warfarin.

Stinging Nettle by Herbal Terra: Common Questions

Does Stinging Nettle by Herbal Terra interact with any medications?
Yes. Based on its ingredients, Stinging Nettle has a known interaction with 164 medications. Use the checker to see how it interacts with a specific drug.
How can one product interact with so many drugs?
Stinging Nettle 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.
Can I take stinging nettle if I'm pregnant or nursing?
No — stinging nettle is best avoided in pregnancy due to traditional concerns about effects on the uterus and lack of safety data. Safety during breastfeeding hasn't been established either, so talk with your doctor or pharmacist for personalized guidance if you're nursing.
What are the most common side effects?
Taken orally, the main side effects are constipation or diarrhea. If you handle the raw fresh plant, touching it can cause stinging, itching, and rash — usually mild and transient, though it can linger over 12 hours.
Does stinging nettle actually help with diabetes?
Research suggests it's possibly effective for lowering blood glucose in people with diabetes, but you'll need to check with your doctor about whether it's right for you, especially since it interacts with diabetes medications and may have additive blood sugar-lowering effects.
What about the other conditions listed — does it help with hay fever, anemia, or asthma?
The evidence we hold for those uses is insufficient to rate, meaning there isn't enough reliable research yet to say whether it works. Your pharmacist or doctor can discuss whether it's worth trying for your specific situation.
Are there any inactive ingredients I should know about?
The only inactive ingredient listed is menstruum, which is the liquid solvent used to extract the nettle's active compounds. It's not a filler — it's part of how a liquid extract is made.
