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.

FGO Organic Nettle Leaf Tea Bags contains one active ingredient: stinging nettle (also called Stinging Nettle). This product has no other inactive ingredients listed.

Nettle leaf has been used traditionally for a range of purposes, though the evidence supporting most of those uses is still being gathered. The one area where research shows real promise is diabetes, where nettle may help lower blood sugar.

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—research suggests it may help lower blood glucose levels. For allergic rhinitis (hay fever), anemia, asthma, benign prostatic hyperplasia (an enlarged prostate), and gingivitis (gum inflammation), the evidence we hold is not yet reliable enough to rate whether nettle works for these conditions.

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 quality varies by product. The most common side effects when taken orally are constipation or diarrhea.

If you handle the raw plant or fresh leaves directly, you may get itching, a rash, or stinging—and in rare cases, swallowing fresh nettle can cause serious swelling of the mouth and throat. There isn't enough safety data to recommend this product during pregnancy—traditional concerns about effects on the uterus mean it's best avoided.

Safety during breastfeeding has not been established either, so talk with your doctor before using it if you're nursing. One rare case of liver injury has been reported in someone taking an herbal tea that contained nettle and other ingredients, though causation is unclear.

  • The most serious interaction on file is rated Moderate.
  • Some involve high-stakes drug classes: anticoagulant / antiplatelet drugs; diabetes medications; lithium.

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.

Nettle tea may be worth considering if you have diabetes and want a traditional herbal option—but only after checking with your pharmacist, especially if you take blood thinners, diabetes drugs, diuretics, or lithium. If you're pregnant or breastfeeding, talk with your doctor first.

People with blood-thinning medications should avoid this product without medical supervision.

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.

Organic Nettle Leaf Tea Bags by FGO: Common Questions

Does Organic Nettle Leaf Tea Bags by FGO interact with any medications?
Yes. Based on its ingredients, Organic Nettle Leaf Tea Bags 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?
Organic Nettle Leaf Tea Bags 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 nettle tea help with my diabetes?
Research suggests stinging nettle is possibly effective for diabetes—clinical studies show it may lower blood glucose levels. That said, you should not use it to replace diabetes medication. Talk with your doctor before adding it to your treatment plan, especially since it can add to the effects of diabetes drugs and cause blood sugar to drop too low.
Can I take this if I'm on warfarin or another blood thinner?
No—not without talking to your doctor first. Stinging nettle is high in vitamin K, which interferes with how blood thinners work and could reduce their protective effect. This is a serious interaction, and your dose may need adjustment if you want to use nettle tea.
What are the side effects of drinking nettle tea?
When taken by mouth, the most common side effects are constipation or diarrhea. If you handle fresh nettle leaves directly, the plant itself can cause itching, a rash, or stinging on your skin. Rarely, swallowing fresh nettle can cause serious swelling in the mouth and throat.
Is it safe to drink nettle tea while pregnant or breastfeeding?
There isn't enough safety data to recommend it during pregnancy—traditional concerns about effects on the uterus mean it's best avoided. Safety during breastfeeding has not been established either. Talk with your doctor before using this product if you're pregnant or nursing.
Can nettle tea help with allergies or hay fever?
The evidence we hold doesn't yet reliably show whether stinging nettle works for allergic rhinitis or hay fever. You'd need to talk with your doctor about proven options for allergy relief.
