HelloPharmacist Scorecard of Neem Alcohol Free by Herbal Terra

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: neem leaf extract in liquid form. Neem is a traditional plant remedy with a long history in Ayurvedic medicine.

The liquid also includes glycerin and water as inactive ingredients to help deliver and preserve the extract.

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).

The evidence supports neem leaf for gingivitis (gum inflammation) and head lice—both rated possibly effective based on available research. It may also help with dental plaque.

For acne and tungiasis (a parasitic skin condition), the evidence isn't established enough to rate it one way or the other. If you're considering neem for any of these uses, chat with your pharmacist or doctor about whether it's a good fit for you.

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 are generally well tolerated when taken orally short-term in adults, though high-quality safety studies haven't been done. Topically, it's also generally well tolerated.

The main topical side effect is contact dermatitis in sensitive individuals. Orally, rare serious effects have been reported—cardiac issues and kidney damage in adults, and in children, neem oil can cause dangerous effects including brain swelling.

In one case, an adult with a glucose metabolism disorder (G6PD deficiency) developed hemolytic anemia from drinking large amounts of neem tea daily for weeks. Neem is not safe during pregnancy—it may affect fertility.

There isn't enough safety data to recommend it while breastfeeding.

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 pharmacist if you're on diabetes medications (risk of low blood sugar), immunosuppressants, or drugs processed by your liver's CYP1A2, CYP2C8, CYP2C9, or CYP3A4 enzymes—neem may raise their levels. Also check if you take P-glycoprotein substrates, which may accumulate in your body.

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 extract is possibly effective for gum disease and lice, but it interacts with a large number of medications through several enzyme pathways. If you take any prescription drugs, especially ones for diabetes, transplant rejection, or liver metabolism, check them against the tool on this page first.

Talk with your pharmacist before starting, and avoid it entirely if you're pregnant or nursing.

Neem Alcohol Free by Herbal Terra: Common Questions

Does Neem Alcohol Free by Herbal Terra interact with any medications?
Yes. Based on its ingredients, Neem Alcohol Free 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 Alcohol Free 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 take if I'm pregnant or breastfeeding?
No. Neem may affect fertility and pregnancy, so you should avoid it during pregnancy. While breastfeeding, there isn't enough safety data, so it's best avoided too. Talk with your OB or midwife if you're interested in neem for any reason during these times.
Can I use neem on my skin?
Yes, neem is generally well tolerated when applied topically—both in children and adults. The main risk is contact dermatitis (skin irritation) in people who are sensitive to it. If you notice rash or irritation, stop and rinse it off.
What is neem supposed to help with?
Neem has good evidence for gingivitis (inflamed gums) and head lice, and may help with dental plaque. For acne and other uses, the evidence isn't established yet. Your dentist or doctor can tell you if it's right for your situation.
Can children take neem?
Neem leaf preparations in adults are generally tolerated, but in children, neem oil especially can cause serious effects. Avoid neem oil in kids. Leaf extracts like this one may be safer, but talk with your pediatrician first.
Does neem interact with other things I eat or drink?
The data we hold covers interactions with medications, not food or other beverages. If you have specific concerns, ask your pharmacist or doctor.
