HelloPharmacist Scorecard of Stinging Nettle Blend by Herb 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.

From our pharmacy team — supplement deep dive

Generated from HelloPharmacist’s pharmacist-curated databases and editorial rules · Last generated Jul 11, 2026

What’s inside

Low disclosure
Ingredient Transparency · database check
Low

Most active ingredients don't disclose an individual amount — you can't tell how much of each you're getting.

Why this rating?
  • The label discloses an exact amount for 0 of its 2 active ingredients.
  • “Certified Organic extract blend” is a proprietary blend — the label gives one combined amount (642 mg) without saying how much of each component you get.

Stinging Nettle Blend contains 2 active ingredients: stinging nettle extract from the fresh, undried aerial parts (leaves and stems) and fresh, undried seeds. These are delivered in a liquid form using cane alcohol and distilled water as inactive ingredients.

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 — see Stinging Nettle's own graded uses on its monograph.

Why this rating?
  • The label markets this product for: respiratory system support.
  • We looked for evidence on: Allergic rhinitis (hay fever), Asthma, Seasonal allergies, Sinus congestion.
  • The closest evidence on file: Stinging Nettle is rated "Insufficient Reliable Evidence To Rate" for Allergic rhinitis (hay fever) (Natural Medicines).
  • Also on file: Stinging Nettle is rated "Insufficient Reliable Evidence To Rate" for Asthma.

For diabetes, the data shows stinging nettle is possibly effective — clinical research suggests it might help lower blood sugar. For other uses listed in our data — allergic rhinitis (hay fever), anemia, asthma, benign prostatic hyperplasia, and gingivitis — the evidence isn't strong enough to rate how well it works.

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 when you use it as directed, though evidence and quality vary by product. The most common side effects taken by mouth are constipation and diarrhea.

One rare case of liver injury has been reported with a multi-ingredient detox tea containing stinging nettle, so watch for abdominal pain or yellowing of skin or eyes. Stinging nettle is not recommended during pregnancy because there isn't enough safety data and traditional use raises concerns about effects on the uterus.

Safety during breastfeeding has not been established either, so talk with your doctor or pharmacist before using it if you're nursing.

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 — Stinging Nettle.
  • The most serious interaction on file is rated Moderate.
  • Some involve high-stakes drug classes: anticoagulant / antiplatelet drugs; diabetes medications; lithium.
  • For scale: 164 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 with your pharmacist if you take blood thinners (Coumadin/warfarin), diabetes medications, diuretics (water pills), or lithium. All four have documented Moderate-severity interactions with stinging nettle.

The bottom line

Scorecard at a glanceFormula with limited ingredient disclosure with no established evidence rating for its marketed use. Moderate medication interactions have been identified, and safety information is well characterized.

This blend may be worth considering if you're looking into natural support for blood sugar, but you need to check it against any blood thinners, diabetes drugs, water pills, or lithium you take first. If you're pregnant or breastfeeding, skip it and talk to your pharmacist.

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 Blend by Herb Pharm: Common Questions

Does Stinging Nettle Blend by Herb Pharm interact with any medications?
Yes. Based on its ingredients, Stinging Nettle Blend 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 Blend contains 2 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.
Will this help my blood sugar?
For diabetes, stinging nettle is rated possibly effective — clinical research suggests it might lower blood sugar. That said, the evidence isn't bulletproof, and products vary in strength. If you're diabetic and interested, talk it through with your pharmacist or doctor first, especially if you're already on diabetes medication.
Can I use this if I'm pregnant?
No — there isn't enough safety data, and traditional use raises concerns about effects on the uterus. It's best avoided during pregnancy. If you're thinking about it, talk with your doctor.
What side effects might I notice?
When taken by mouth, the most common are constipation and diarrhea. If you touch the fresh plant directly, you might get itching, rash, and stinging on your skin. One rare case of liver injury was reported with a multi-ingredient detox tea containing nettle, so if you develop belly pain or yellowing of skin or eyes, stop and call your doctor.
Is it safe to take while breastfeeding?
Safety during breastfeeding hasn't been established, so it's best to avoid it until you talk with your doctor or pharmacist about your personal situation.
What's the difference between the aerial parts and the seed extract in this blend?
The product combines extract from the fresh leaves and stems (aerial parts) and fresh seeds of stinging nettle. Both forms are in the blend to give you a broader profile of the plant — they interact with the same medications, but may offer slightly different compounds.
