HelloPharmacist Scorecard of Stinging Nettle by Mountain Meadow Herbs

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 Oct 8, 2026

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.

The active ingredient is stinging nettle leaf extract, made from the leaves of the stinging nettle plant. It is the only active ingredient listed in this liquid.

The inactive ingredients are glycerin and distilled water.

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).

The only rating in our data that reaches a usable level is for diabetes, which is rated Possibly Effective. For allergic rhinitis (hay fever), anemia, asthma, benign prostatic hyperplasia (BPH, an enlarged prostate), and gingivitis (gum inflammation), the rating is Insufficient Reliable Evidence To Rate, so the evidence for those uses isn't established in the data we hold.

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 for most adults when used as directed, though evidence and product quality vary. The most common side effects taken orally are constipation and diarrhea.

Applied to skin, contact with the raw plant can cause itching, rash, and stinging. A case report describes liver injury in a woman who had taken an herbal liver detox tea containing stinging nettle and other ingredients.

In pregnancy, the safety data is rated Likely Unsafe, and traditional concerns about effects on the uterus mean it is best avoided. Breastfeeding safety has not been established, so talk with your doctor before using it while nursing.

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 — 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.

Double-check antidiabetes drugs, diuretics (water pills), lithium, and warfarin (Coumadin) before taking this product. Every interaction in our data is rated Moderate, and none is rated Major.

Stinging nettle may affect blood sugar, fluid balance, lithium levels, and warfarin's effects, so ask your own doctor or pharmacist to review your full medication list first.

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.

This product may interest adults who are considering stinging nettle, though its strongest rating is only Possibly Effective, for diabetes. Anyone taking antidiabetes drugs, diuretics, lithium, or warfarin should be especially careful and talk it over with their own doctor or pharmacist first.
