HelloPharmacist Scorecard of Fresh Nettle Leaf by Sun God Medicinals Ra Herbals

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 30, 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: stinging nettle leaf extract, which is the above-ground part of the plant steeped in a liquid base. The formula also includes cane alcohol and distilled water as inactive ingredients to preserve and deliver the extract.

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 clinical research showing it may help lower blood sugar. For hay fever, anemia, asthma, benign prostatic hyperplasia (enlarged prostate), and gingivitis, we don't hold enough reliable evidence yet to say whether it works — the data we have is insufficient to rate it either way.

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 by most adults when used as directed, though constipation and diarrhea have been reported. Rare case reports describe liver enzyme elevation after extended use of nettle-containing products; if you develop abdominal pain or yellowing of skin or eyes, contact your doctor right away.

Fresh nettle leaves applied to skin cause localized itching, rash, and stinging — sometimes lasting more than 12 hours — and placing the fresh leaf in your mouth can trigger severe swelling and pain. This product is not recommended during pregnancy, as traditional use and some safety concerns advise against it.

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

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 product, double-check with your doctor or pharmacist if you're on blood thinners like warfarin, diabetes medications, diuretics (water pills), or lithium. All four categories interact with stinging nettle, and the effects could be serious if dosing isn't adjusted.

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 may help lower blood sugar and could interest people exploring it for diabetes, but the interactions with blood thinners, diabetes drugs, diuretics, and lithium are real and worth checking first. If you're on any prescription medications — especially those four types — confirm with your doctor or pharmacist before adding this product.

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.

Fresh Nettle Leaf by Sun God Medicinals Ra Herbals: Common Questions

Does Fresh Nettle Leaf by Sun God Medicinals Ra Herbals interact with any medications?
Yes. Based on its ingredients, Fresh Nettle Leaf 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?
Fresh Nettle Leaf 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.
Will stinging nettle help my blood sugar?
Clinical research shows stinging nettle might lower blood glucose in people with diabetes, so it's rated possibly effective for that purpose. That said, if you're already taking diabetes medication, combining them could push your blood sugar too low — that's why checking with your doctor first matters.
Can I use this if I'm pregnant?
No — stinging nettle is rated likely unsafe in pregnancy because of traditional concerns about effects on the uterus and lack of solid safety data. Talk with your doctor before taking it if you're pregnant or planning to become pregnant.
Is it safe to breastfeed while taking this?
Safety during breastfeeding hasn't been established, so we don't have enough data to say either way. Talk with your doctor or pharmacist before using it if you're nursing.
What side effects should I watch for?
The most common are constipation and diarrhea. Topical contact with fresh nettle leaves causes itching, rash, and stinging — usually lasting a few hours but sometimes longer. Rare cases of liver enzyme changes have been reported; if you develop belly pain or yellowing of skin or eyes, stop and contact your doctor.
Why is this a liquid rather than a capsule?
The product facts provided don't explain the formulation choice. A liquid extract allows the active ingredient to be absorbed quickly, but your pharmacist can tell you more about why this brand chose this form.
