HelloPharmacist Scorecard of Organic Neem Powder by Herbal Hills

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.

Organic Neem Powder contains one active ingredient: organic neem powder. Neem is derived from the neem tree and has been used traditionally for oral and topical purposes.

There are no other active ingredients in this product.

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?
  • 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: Dental plaque — rated "Possibly Effective" (Natural Medicines).
  • On file: Gingivitis — rated "Possibly Effective" (Natural Medicines).
  • On file: Lice — rated "Possibly Effective" (Natural Medicines).

Neem powder is possibly effective for gingivitis, lice, and dental plaque based on available evidence. For acne and tungiasis, the evidence is insufficient to rate its effectiveness.

If you're considering neem for one of these uses, talk with your doctor or pharmacist about whether the evidence supports it for 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 is rated likely unsafe in pregnancy and should be avoided—research suggests it may affect fertility. While breastfeeding, there isn't enough safety information, so it's best avoided.

If you're pregnant, planning pregnancy, or nursing, talk with your doctor or pharmacist before using this product.

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 taking this product, check with your doctor or pharmacist if you take any of the following: CYP3A4 substrates (a broad category including many common drugs), CYP1A2, CYP2C8, or CYP2C9 substrates, P-glycoprotein substrates, immunosuppressants, or diabetes medications. Neem may raise drug levels and effects or reduce how well some medications work.

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 powder may be worth considering if you're dealing with gingivitis, lice, or dental plaque and want a plant-based option—the evidence supports possible benefit for these uses. However, it interacts with a very large number of medications through multiple enzyme pathways, so if you take any prescription drugs, you must check them with your pharmacist or doctor first.

Neem is not for pregnancy or breastfeeding. Run your medication list through the checker on this page before starting.

Organic Neem Powder by Herbal Hills: Common Questions

Does Organic Neem Powder by Herbal Hills interact with any medications?
Yes. Based on its ingredients, Organic Neem Powder 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?
Organic Neem Powder 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.
Can I take neem powder if I'm trying to get pregnant or I'm pregnant?
No—neem is rated likely unsafe in pregnancy and may affect fertility. If you're pregnant, planning pregnancy, or think you might be, talk with your doctor or pharmacist before using neem.
Is neem powder safe to take by mouth long-term?
Neem leaf powder is generally well tolerated short-term in adults, but high-quality long-term safety studies haven't been done. It's important to note that neem oil and seed extracts are toxic if swallowed, so stick to leaf preparations. If you're considering long-term use, discuss it with your pharmacist.
What should I know about neem and my diabetes medication?
Neem itself can lower blood sugar, and research shows it works this way even in people already taking diabetes drugs like metformin. Taking neem with your diabetes medication could cause your blood sugar to drop too much. Check with your doctor or pharmacist before adding neem if you take any diabetes drug.
Does neem powder actually work for gingivitis?
Neem is possibly effective for gingivitis based on current evidence. The research supports it as a candidate treatment, though it's not proven definitive. If you're interested in using it for gum health, talk it over with your dentist or doctor.
Can I use neem powder topically on my skin?
Yes—neem is well tolerated when applied to the skin in both children and adults. The main side effect to watch for is contact dermatitis (skin irritation) in people with sensitive skin. If irritation develops, stop use and rinse with water.
Is neem powder safe while breastfeeding?
There isn't enough reliable safety information about neem while breastfeeding, so it's best avoided. If you're nursing and interested in neem, talk with your doctor or pharmacist for personalized advice.
