HelloPharmacist Scorecard of Neem Leaf Capsules 400 mg by NeemAura

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

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.

NeemAura Neem Leaf Capsules contains a single active ingredient: 400 mg of neem leaf per capsule. Neem is a tree native to India whose leaves have been used traditionally for skin, oral, and immune health.

The capsule itself is made from pullulan, an inactive ingredient that serves as the capsule material.

Does it work?

Couldn't assess
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 assessable

We hold no graded evidence for this product's ingredients for its stated purpose.

Why this rating?
  • The label markets this product for: supports proper immune system function.
  • Our graded evidence for these ingredients doesn't cover that particular purpose.

The evidence for neem leaf is mixed. It's possibly effective for gingivitis (gum inflammation), dental plaque, and head lice, based on clinical research.

For acne and tungiasis (a parasitic skin infection), the evidence isn't strong enough yet to rate it reliably. If you're taking it for one of those first three uses, there's a reasonable chance it could help — but talk it over with your doctor or dentist to see if it fits your situation.

The evidence, ingredient by ingredient Neem

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.

Neem leaf taken by mouth seems to be tolerated reasonably well in adults, though rigorous safety testing hasn't been done. The biggest concern is that neem is unsafe in pregnancy — the evidence suggests it could affect fertility and the developing baby, so you should avoid it if you're pregnant or trying to conceive.

There isn't enough safety data to recommend it while breastfeeding either, so talk with your doctor or pharmacist before using it in that situation. Topically, neem appears safe for both adults and children.

Rare serious effects reported in adults taking neem orally include heart rhythm problems and kidney damage; in children, neem oil can cause severe toxicity. Contact dermatitis (skin irritation) is the most common side effect when applied to skin in sensitive individuals.

Side effects, ingredient by ingredient Neem

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 — Neem.
  • The most serious interaction on file is rated Moderate.
  • Some involve high-stakes drug classes: immunosuppressants / transplant drugs; diabetes medications.
  • For scale: 1,014 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, check with your doctor or pharmacist if you're on antidiabetes drugs (metformin, sulfonylureas, or insulin) — neem can lower blood sugar and increase the risk of hypoglycemia. Also double-check any medications broken down by liver enzymes (CYP1A2, CYP2C8, CYP2C9, CYP3A4) or transported by P-glycoprotein, as neem may raise their levels.

And if you take immunosuppressants, neem might reduce their effectiveness. Use the medication search tool on this page to verify your exact drugs.

The bottom line

Scorecard at a glanceFully disclosed formula with no assessable stated purpose. Moderate medication interactions have been identified, and safety information is well characterized.

NeemAura Neem Leaf Capsules is worth considering if you're looking at neem for gingivitis, plaque, or lice and aren't pregnant, breastfeeding, or taking diabetes medications or other drugs metabolized by your liver. Because neem interacts with so many medication pathways, you'll need to check your specific prescriptions before starting.

Have your doctor or pharmacist review your medications against this product before you begin.

Neem Leaf Capsules 400 mg by NeemAura: Common Questions

Does Neem Leaf Capsules 400 mg by NeemAura interact with any medications?
Yes. Based on its ingredients, Neem Leaf Capsules 400 mg has a known interaction with 1,013 medications. Use the checker to see how it interacts with a specific drug.
How can one product interact with so many drugs?
Neem Leaf Capsules 400 mg 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.
Is neem leaf safe during pregnancy?
No. The safety data advises against neem during pregnancy because it may affect fertility and the developing baby. If you're pregnant or trying to conceive, avoid this product and talk with your doctor about alternatives.
Can I breastfeed while taking neem leaf capsules?
There isn't enough safety data to know either way. To be safe, it's best to talk with your doctor or pharmacist before using neem while breastfeeding — they can help you decide what's right for you and your baby.
Does neem leaf actually work for acne?
The evidence isn't strong enough to say reliably. Neem is possibly effective for gingivitis, plaque, and lice, but for acne, we don't have enough high-quality research to rate it.
What's the most common side effect?
When applied to skin, contact dermatitis (itching or redness) can happen in people with sensitive skin. Taken by mouth, neem leaf seems to be tolerated well overall, though serious effects like heart rhythm problems are rare.
Will neem leaf capsules affect my diabetes medication?
Possibly — neem can lower blood sugar on its own, so combining it with antidiabetes drugs like metformin increases your risk of low blood sugar (hypoglycemia). Check with your doctor or pharmacist before starting.
What's in these capsules besides neem?
The capsule is made from pullulan, which is an inactive ingredient that holds the neem powder. There are no other active ingredients.
