HelloPharmacist Scorecard of 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.

What’s inside

Low disclosure
Ingredient Transparency · database check
Low

Most active ingredients don't disclose an individual amount — you can't tell how much of each you're getting.

Why this rating?
  • The label discloses an exact amount for 0 of its 1 active ingredient.

Neem Powder by Herbal Hills contains one active ingredient: neem powder. Neem is a plant extract that has been used in traditional medicine for oral health and skin conditions.

There are no inactive ingredients listed for 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
Moderate

Some clinical evidence supports this product's ingredients for its stated purpose, but it isn't conclusive.

Why this rating?
  • The label markets this product for: natural cleansing and skin purification.
  • We looked for evidence on: Acne, Psoriasis, Wound healing, Dental plaque, Gingivitis, Intestinal parasite infection — and 4 related terms.
  • The strongest evidence on file: Neem is rated "Possibly Effective" for Dental plaque (Natural Medicines).
  • Also on file: Neem is rated "Possibly Effective" for Gingivitis, Lice.
  • Also on file: Neem is rated "Insufficient Reliable Evidence To Rate" for Acne, Intestinal parasite infection, Psoriasis, Wound healing.

The evidence supports neem powder for a few specific uses. It's possibly effective for gingivitis (gum inflammation) and dental plaque—so it may help if you're dealing with gum disease or want to support oral health.

It's also possibly effective against lice. For acne and tungiasis (a parasitic skin infection), the evidence isn't strong enough yet to say whether it works.

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 preparations appear to be well tolerated when taken by mouth in adults over the short term, though thorough safety studies haven't been done. The main concern is that neem oil and seed extracts can be toxic if swallowed, and neem oil is dangerous in children and can cause serious harm.

Topical neem (applied to skin) is generally well tolerated, though some people may get contact dermatitis if their skin is sensitive. Rare but serious side effects reported with oral neem leaf include heart rhythm problems and kidney damage in adults.

In people with G6PD deficiency (a genetic condition affecting red blood cells), neem can trigger hemolytic anemia. Neem is likely unsafe in pregnancy and should be avoided—it may affect fertility.

There isn't enough safety data for breastfeeding, so it's best avoided then too.

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 taking Neem Powder, double-check with your pharmacist or doctor if you take antidiabetes drugs (diabetes medications), immunosuppressants (drugs that weaken your immune system), or any medications broken down by your liver through CYP1A2, CYP2C8, CYP2C9, or CYP3A4 pathways—or moved by P-glycoprotein kidney transporters. These are theoretical risks seen in lab work, not yet confirmed in people, but they're worth confirming for your specific medications.

The bottom line

Scorecard at a glanceFormula with limited ingredient disclosure with some supporting evidence for its stated purpose. Moderate medication interactions have been identified, and safety information is well characterized.

Neem powder may help with gum disease, dental plaque, or lice if you're looking for a plant-based option. If you take diabetes medication, immunosuppressants, or drugs your liver processes, you'll need to check with your doctor or pharmacist before adding neem—the interaction risks are real, even if they haven't been seen in people yet.

Avoid it entirely if you're pregnant, breastfeeding, or giving it to children.

Neem Powder by Herbal Hills: Common Questions

Does Neem Powder by Herbal Hills interact with any medications?
Yes. Based on its ingredients, 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?
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.
Is neem powder safe to use for my teeth and gums?
Neem powder is possibly effective for gingivitis and dental plaque, so it may support your oral health. Topical neem is generally well tolerated, though sensitive skin may react with contact dermatitis. For internal use, neem leaf preparations appear well tolerated in adults short-term, but avoid neem oil—it can be toxic if swallowed.
Can I take neem powder while pregnant or breastfeeding?
No, neem is likely unsafe during pregnancy—it may affect fertility. There isn't enough safety data for breastfeeding, so it's best to avoid it then too. Talk with your doctor or midwife if you're considering it during either period.
What are the side effects of neem powder?
Taken by mouth, neem leaf seems well tolerated in most adults, though thorough safety testing hasn't been done. Contact dermatitis can occur if you apply it to sensitive skin. Rare serious effects reported include heart rhythm problems and kidney damage. In people with G6PD deficiency, neem can cause hemolytic anemia.
Can I give neem powder to my child?
No, neem oil is dangerous in children and can cause serious harm. Oral neem leaf in children hasn't been studied enough to know it's safe, so it's best avoided.
Does neem powder work for acne?
The evidence for acne isn't strong enough yet to say whether neem works—the data we have shows insufficient reliable evidence to rate it for that use.
