HelloPharmacist Scorecard of Organic Neem Leaf Powder by Pure Indian Foods

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 11, 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 is pure neem leaf powder—a single active ingredient with no added actives. Neem is a plant from the Indian subcontinent traditionally used in Ayurvedic practice.

The powder form is made from dried, ground neem leaves.

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 Neem's overall clinical evidence instead.

Moderate

Some clinical evidence supports Neem for:

Why this rating?
  • The label markets general wellness (“supports healthy detoxification”), not a specific health condition, so there is no single claim to grade against clinical-evidence data.
  • Since the label doesn't commit to one use, we graded the ingredient's overall clinical evidence instead.
  • On file: Dental plaque — rated "Possibly Effective" (Natural Medicines).
  • On file: Gingivitis — rated "Possibly Effective" (Natural Medicines).
  • On file: Lice — rated "Possibly Effective" (Natural Medicines).

The evidence for neem leaf supports its use for a few specific purposes. It's possibly effective for gingivitis (gum inflammation), dental plaque buildup, and head lice.

For acne and tungiasis (a parasitic skin infection), the evidence isn't strong enough for us to rate it. If you're thinking about neem for something else, the data we hold doesn't speak to that.

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 powder is generally well tolerated when taken by mouth in the short term. That said, high-quality safety testing hasn't been done, and serious side effects—though rare—have been reported in adults, including heart rhythm problems and kidney damage.

In children, neem oil taken by mouth can cause serious harm, though leaf preparations are less of a concern. Topically, neem seems safe and well tolerated; the main risk is contact dermatitis in people with sensitive skin.

One case report described a man with a genetic blood condition (G6PD deficiency) who developed hemolytic anemia and jaundice after drinking large amounts of neem tea daily for weeks—his symptoms resolved once he stopped. You should avoid this product during pregnancy; the safety data advises against it.

Breastfeeding safety isn't well established, so it's best avoided while nursing as well.

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.

Check your exact medications before taking this product if you take diabetes drugs (risk of low blood sugar), heart or blood pressure medications, immunosuppressants, or any medication your doctor says your liver breaks down. No interactions are documented for the ingredients we could check beyond the theoretical enzyme and transport interactions listed—but that doesn't mean none exist, so the checker below is your best next step.

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.

Neem leaf powder is possibly effective for gum disease and lice, and it's generally well tolerated short-term by adults. But it interacts with a wide range of medications, especially diabetes drugs and anything your liver processes—so check your medications before you start.

Pregnant or breastfeeding? Skip it.

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.

No. The safety data advises against neem during pregnancy because it may affect fertility and your growing baby. Talk with your doctor or pharmacist for personalized advice before use.
Is neem leaf powder safe to take by mouth?
