- CHEMISTRY: Relevant reported constituents include myristicin; elemicin; safrole; constituent presence alone does not establish clinical efficacy.
Uses & Evidence
Traditional / historical use
Documented traditional use — not a claim of established efficacy.
TRADITIONAL: Nutmeg has been used for digestive complaints; flavoring; this records historical/traditional use and does not establish efficacy.
MODERATE · regulatory monograph · EMA European Union herbal monographs and list entries
Modern evidence
EVIDENCE: For the major use set (digestive complaints; flavoring), the evidence assessment is insufficient: Insufficient clinical evidence.

Preparation
Forms used traditionally
A listed form does not imply it suits every plant part, or that one preparation is interchangeable with another — see the plant’s own notes below.
PREPARATION: The medicinal material is seed; aril (mace); traditional and modern forms include infusion/tea, tincture, powder/capsule, extract. No dose or potency is specified.
MODERATE · regulatory monograph · EMA European Union herbal monographs and list entries
Preparation-specific evidence should not be generalized across extracts, teas, oils, or whole herb.
Safety
Cats & dogs
- High risk
Large amounts of ingested nutmeg can cause vomiting, dry mouth, agitation, difficulty walking or standing, hallucinations, pupil changes, and fast heart rate.
Intrinsic toxicity · OTHER · Nutmeg; amount described as large, specific form not specified · MODERATE · poison_control_database · When Pumpkin Spice is Not So Nice - ASPCA
- High risk
Very large nutmeg ingestions can cause myristicin toxicity, including neurologic, cardiovascular, gastrointestinal, and potentially seizure-related effects.

- Low concern
Nutmeg in the small amounts typically present in recipes is very unlikely to cause serious toxicity, although mild stomach upset may occur.
