Myristica fragrans Houtt.
Also known as Jatiphala
Pronounced Nutmeg: NUT-meg. Mace: mayss. Jatiphala: jah-tee-PHAH-lah. Myristica fragrans: my-RIS-tih-kuh FRAG-ranz.
Warm, dry, and aromatic: a carminative, astringent grahi that kindles a cold digestive fire and firms a loose, atonic, damp bowel, and in a small pinch eases an overwound mind into sleep, but a narrow-margin spice that turns deliriant and dangerous at gram-scale doses.
Avoid medicinal and large doses in pregnancy. Nutmeg carries a long traditional reputation as an emmenagogue and abortifacient, its psychoactive constituent myristicin crosses the placenta, and modern safety references classify the seed as not for use during pregnancy. Everyday culinary amounts sprinkled in food are generally regarded as safe, but concentrated or repeated medicinal doses should be avoided throughout pregnancy. Source: AHPA Botanical Safety Handbook, 2nd ed. (Gardner & McGuffin, 2013), Myristica fragrans seed rated not for use during pregnancy; corroborated by modern clinical-herb references and toxicology reviews on myristicin.
Avoid medicinal doses during breastfeeding; insufficient modern data on transfer of myristicin into milk or effects on the nursing infant. Ordinary culinary use in food is generally regarded as acceptable, but concentrated or repeated medicinal dosing should be avoided while nursing unless directed by a qualified practitioner. Source: AHPA Botanical Safety Handbook, 2nd ed.; general modern lactation-herb consensus (insufficient data, precautionary avoidance at medicinal doses).
Not recommended at medicinal doses in children, and larger amounts are outright hazardous: pediatric nutmeg poisoning is well documented and the narrow margin is unforgiving in a small body. Culinary amounts in food are acceptable. Any medicinal use in children should be only under qualified supervision at reduced, weight-appropriate doses, and the concentrated oil and any dose approaching a gram must be kept out of reach. Source: myristicin toxicity reviews and poison-center case reports; AHPA Botanical Safety Handbook, 2nd ed.
Nutmeg has a genuinely narrow therapeutic margin and must be treated with respect: the culinary and small medicinal amounts are safe, but the same volatile oil that makes it a sedative in a pinch makes it a dangerous deliriant in a spoonful. Doses of roughly 5 g and above (about one to two whole nutmegs, delivering enough myristicin and elemicin) can cause serious, occasionally fatal intoxication: nausea and vomiting, flushing, dry mouth, blurred vision, tachycardia and palpitations, agitation and anxiety, dizziness, a sense of impending doom, and hallucinations or delirium, with a long, wretched hangover-type course lasting 24 to 48 hours or more. This is not a recreational agent, and its abuse should be actively discouraged. Keep medicinal use to small doses (well under 1 g at a time, ordinarily 250 to 500 mg), and reserve any larger or repeated dosing for a qualified practitioner. Avoid entirely in people with psychiatric conditions, seizure disorders, or significant liver disease. Hepatic and renal stress has been reported at high intake.
Pregnancy (medicinal or large doses), on its traditional emmenagogue and reputed abortifacient standing and the placental transfer of myristicin (culinary amounts in food are generally regarded as acceptable). Lactation, at medicinal doses, on insufficient safety data. Young children, at medicinal doses, given the narrow margin and the severity of pediatric nutmeg poisoning. Psychiatric illness, seizure disorders, and significant hepatic or renal disease. Acute, hot, or infective diarrhea and dysentery with fever, blood, or mucus, which need assessment rather than a binding warming spice. Known hypersensitivity. Concurrent use of MAO inhibitors, serotonergic antidepressants, or other psychoactive or sedating drugs (see drug interactions). Never for recreational intoxication.
Nutmeg is a widely cultivated tropical tree crop (Indonesia, Grenada the 'Isle of Spice', India, Sri Lanka), not a wild-harvested or at-risk species, and it does not appear on United Plant Savers at-risk listings. The stewardship concerns are agricultural and social rather than conservational: prefer organically and sustainably grown, fair-trade sourced nutmeg and mace from suppliers who support equitable smallholder livelihoods, since mace in particular is a limited, labor-intensive yield (one thin aril per seed). Given the herb's toxic potential, responsible stewardship also means dispensing it in small, clearly labeled, dose-bounded amounts.
Not a plant of the biblical Near East and not named in canonical Scripture. Myristica fragrans is native to the Banda Islands of Indonesia and was unknown to the Mediterranean world of the Bible; it entered Old World commerce only in the medieval period through Arab and later Portuguese and Dutch spice traders. Its deep medicinal lineage is Asian: Ayurvedic (Jatiphala), Unani, and Chinese (Rou Dou Kou). Included here as a cross-traditional materia medica entry, honestly sourced to its Southeast Asian origin rather than to Scripture.
