HelloPharmacist Scorecard of Organic Neem by Herbal Secrets

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

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 contains one active ingredient: organic neem powder. Neem is a tree native to India, and traditional medicine has used its leaves for centuries.

The powder here is made from the leaf, which is where most of neem's studied effects come from.

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: blood purifier and detoxicant.
  • Our graded evidence for these ingredients doesn't cover that particular purpose.

The evidence supports neem for a few specific uses. It's possibly effective for gingivitis (gum inflammation) and for treating lice when applied topically.

It may also help with dental plaque. For acne and tungiasis (a parasitic skin infection), we don't have enough reliable evidence 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 powder seems to be well tolerated when taken by mouth in adults over the short term, though rigorous safety studies haven't been done. The real concern is that neem oil and seed extracts—different forms—can be toxic if swallowed, and in children, oral neem oil has caused serious effects.

When applied to skin, neem is generally well tolerated, though a small number of people with sensitive skin may develop contact dermatitis. Rarely, oral neem leaf has been linked to heart rhythm problems and kidney damage in adults, and hemolytic anemia (breakdown of red blood cells) in people with a specific blood enzyme deficiency.

Neem should be avoided during pregnancy—the safety data advises against it. There isn't enough reliable information to know whether it's safe while breastfeeding, so it's best to avoid it then too.

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 this product, talk to your doctor or pharmacist if you take any Moderate-severity medications that depend on liver processing (CYP1A2, CYP3A4, CYP2C9, or CYP2C8 substrates), P-glycoprotein substrates, immunosuppressants, or diabetes medications. Neem may raise drug levels or lower blood sugar, and it may reduce how well immune suppressors work.

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.

Neem powder may help with gum health, lice, or dental plaque if you're looking for a botanical option. But because it interacts with over 1,000 individual medications through several liver enzyme pathways, and because it can lower blood sugar and interfere with immune-suppressing drugs, you need to clear it with your own doctor or pharmacist before you start—especially if you take any prescription medications, diabetes drugs, or transplant rejection medications.

Organic Neem by Herbal Secrets: Common Questions

Does Organic Neem by Herbal Secrets interact with any medications?
Yes. Based on its ingredients, Organic Neem 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 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 safe to use while pregnant or breastfeeding?
No. Neem should be avoided during pregnancy—the safety data advises against it. There isn't enough reliable information to say whether it's safe while breastfeeding, so it's best to avoid it then too. Talk to your doctor or pharmacist if you're pregnant, planning to become pregnant, or breastfeeding.
Does neem actually work for acne?
We don't have enough reliable evidence to say. The data we hold rates acne as having insufficient evidence, so it's not clear whether neem helps.
Can I use neem powder on my skin?
Yes, neem is generally well tolerated when applied topically in both children and adults. A small number of people with sensitive skin may develop contact dermatitis, so test a small amount first if you're concerned.
What are the most common side effects if I take neem by mouth?
Neem leaf powder seems well tolerated in adults over the short term. The main concern is that it can raise levels of certain medications in your blood. Rarely, serious effects like heart rhythm problems have been reported, so this is another reason to check with your doctor first.
Is neem safe for children?
Neem leaf powder is not well studied in children. More importantly, neem oil—a different form—can cause serious adverse effects if swallowed by children, so it's best avoided. Always talk to your pediatrician before giving any supplement to a child.
Will neem interfere with my diabetes medication?
Possibly. Some clinical research shows neem can lower blood sugar levels in people with type 2 diabetes, including those taking metformin. This means there's a risk of low blood sugar (hypoglycemia) if you combine neem with diabetes drugs. Check with your doctor or pharmacist before starting it.
