HelloPharmacist Scorecard of Nutmeg 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: a dried nut liquid extract from certified organic Nutmeg. The extract is made using a menstruum—a liquid base used to concentrate the plant's compounds.

You're getting nutmeg in a concentrated liquid form rather than the ground spice you'd use in cooking.

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

This is a single-ingredient Nutmeg product and its label doesn't state a use — see Nutmeg's own graded uses on its monograph.

Why this rating?
  • We looked at the product name, claims, and label statements and couldn't find a stated purpose to grade.

The evidence for nutmeg as a supplement isn't established in the data we hold. The uses listed—dental caries (tooth decay), diarrhea, and halitosis (bad breath)—all carry a rating of insufficient reliable evidence, meaning there's not enough solid research to say whether this product actually works for those purposes.

The evidence, ingredient by ingredient Nutmeg

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.

When you use nutmeg as a food spice, it's generally well tolerated. The problem is dose.

At higher doses—especially in concentrated supplement form—nutmeg can be toxic. The safety notes here are clear: avoid medicinal amounts and stick to normal food use only.

Food amounts are likely fine, but concentrated supplements lack adequate safety data. Serious overdose effects are rare but real, and they're serious: hallucinations, seizures, heart problems, and psychiatric events have been reported.

At food-spice levels, the most common side effect is allergic contact dermatitis in sensitive people. Pregnancy and lactation data show nutmeg as likely safe at food amounts, but safety in pregnancy at higher doses is possibly unsafe—so again, stick to culinary amounts if you're pregnant or nursing.

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 — Nutmeg.
  • The most serious interaction on file is rated Moderate.
  • For scale: 528 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, double-check it against any CNS depressants you take (sedatives, sleep aids, some pain relievers), drugs metabolized by the liver enzyme CYP1A2, anticholinergic or cholinergic medications, and phenobarbital. All of these have documented Moderate interactions with nutmeg.

Check your own medication Run your meds through the checker above

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.

If you're thinking about this as a supplement rather than as seasoning, pause and talk to your pharmacist first. The evidence for its intended uses isn't there, and concentrated doses carry real safety risks.

It's safest as food. If you do take it and you're on any medication—especially sedatives, seizure drugs, or anything processed by your liver—check it with us before you start.

Anticholinergic Drugs

Theoretically, concomitant use of nutmeg and anticholinergic drugs might decrease the effectiveness of either agent.
Animal research suggests that nutmeg extract can inhibit acetylcholinesterase and might increase acetylcholine levels.

Likelihood Possible Evidence D
Cholinergic Drugs

Theoretically, concomitant use of nutmeg with other cholinergic drugs might have additive effects and increase the risk of cholinergic side effects.
Animal research suggests that nutmeg extract can inhibit acetylcholinesterase and might increase acetylcholine levels.

Likelihood Possible Evidence D
Cns Depressants

Theoretically, nutmeg might increase the risk of additive sedation when taken with CNS depressants.
Animal studies suggest that nutmeg extracts and several volatile oils in nutmeg, such as methyleugenol, isoeugenol, safrole, myristicin, trimyristin, 1,8-cineole, and geranyl acetate, have sedative effects. One animal study shows that petroleum ether extracts of nutmeg can potentiate the effects of pentobarbital or phenobarbital. However, evidence from other animal research suggests that the nutmeg constituent myristicin can actually reduce sleeping time in rats pretreated with phenobarbital.

Likelihood Possible Evidence D
Cytochrome P450 1A2 (Cyp1A2) Substrates

Theoretically, nutmeg might decrease levels of drugs metabolized by CYP1A2.
Animal research suggests that intraperitoneal injections of myristicin, a constituent of nutmeg, can induce CYP1A2.

Likelihood Possible Evidence D
Phenobarbital (Luminal)

Theoretically, nutmeg might increase or decrease the effects and adverse effects of phenobarbital.
Some animal research suggests that myristicin, a constituent of nutmeg, can reduce sleeping time in rats pretreated with phenobarbital. However, other animal research suggests that petroleum ether extract of nutmeg can potentiate the effects of phenobarbital.

Nutmeg by Herbal Terra: Common Questions

Does Nutmeg by Herbal Terra interact with any medications?
Yes. Based on its ingredients, Nutmeg has a known interaction with 528 medications. Use the checker to see how it interacts with a specific drug.
How can one product interact with so many drugs?
Nutmeg 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 this safe to use while pregnant or breastfeeding?
At food-spice amounts, nutmeg is likely safe in both pregnancy and lactation. But this is a concentrated supplement, not cooking spice, and safety data at higher doses in pregnancy shows it's possibly unsafe. If you're pregnant or nursing, stick to nutmeg as food seasoning only and talk to your doctor or pharmacist before taking a supplement.
Will this supplement actually help with diarrhea or bad breath?
The evidence isn't there yet. Diarrhea and halitosis both carry insufficient reliable evidence ratings, which means we don't have solid research showing this works for those purposes.
Is nutmeg supplement safe at any dose?
As a food spice, yes—it's generally well tolerated. But this is a concentrated extract, and larger doses can be toxic and cause serious poisoning, including hallucinations, heart problems, and psychiatric effects. Stick to normal food use only.
What are the side effects if I take too much?
High doses are rare but serious: hallucinations, dizziness, confusion, seizures, abnormal heartbeat, and psychiatric symptoms have been reported. Deaths from nutmeg overdose have also been documented. At food amounts, allergic skin reactions are the most common concern.
Does this ingredient interact with my sleep medication?
Yes, theoretically. Nutmeg may add to the sedating effect of CNS depressants like sleep aids or sedatives, potentially making you drowsier. Check your exact medication with us before starting this supplement.
