HelloPharmacist Scorecard of Nettle Leaf 300 mg by Eclectic Herb

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 Aug 27, 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.

This product contains one active ingredient: freeze-dried stinging nettle leaf at 300 mg per capsule. The capsule itself is made with hypromellose, a standard inactive ingredient used in supplement capsules.

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 support.
  • We looked for evidence on: Asthma, Allergic rhinitis (hay fever), bronchial health, lung function.
  • 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.

The data we hold shows stinging nettle is possibly effective for diabetes. For allergic rhinitis (hay fever), anemia, asthma, benign prostatic hyperplasia (BPH), and gingivitis, the evidence isn't established — there's insufficient reliable data to say whether it works for these uses.

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.

When taken by mouth as directed, stinging nettle is generally well tolerated, though quality varies by product. Some people report constipation or diarrhea.

If you touch the fresh plant, you may get a localized rash, itching, or stinging sensation. Pregnancy safety data advises against taking this product — there's traditional concern about effects on the uterus.

Safety during breastfeeding hasn't been established either, so avoid it until you talk with your doctor. A rare case of liver injury has been reported, though it involved nettle in a multi-ingredient tea, not nettle alone.

Side effects, ingredient by ingredient Stinging Nettle

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 — 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.

Before you take this, check with your doctor or pharmacist if you're on blood thinners like warfarin, diabetes medications, diuretics (water pills), or lithium. All of these have Moderate-severity interactions documented with stinging nettle.

The bottom line

Scorecard at a glanceFully disclosed formula with no established evidence rating for its marketed use. Moderate medication interactions have been identified, and safety information is well characterized.

Nettle Leaf may be worth considering if you're interested in blood sugar support, but it's not right for you if you take blood thinners, diabetes drugs, water pills, lithium, or if you're pregnant or breastfeeding. Check your medications with your doctor or pharmacist before starting.

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.
