Chemistry notes

  • 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-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.
