Myristica fragrans (scientific name: Myristica fragrans) is an evergreen tree plant of the Myristica fragrans family. Small trees; young branches are slender. This species is a famous spice and medicinal plant in the tropics. The fruits are harvested in winter and spring when they are ripe.

Its seeds are used as medicine to treat cold dysentery, abdominal cold pain, vomiting, etc.; external use can be used as a parasite repellent to treat rheumatic pain. In addition, it can also be used as condiments and industrial oil raw materials. Myristica fragrans is an important spice and medicinal plant.


  • The ethanol extract of nutmeg has antifungal and antimicrobial effects, and its terpenoids have antibacterial effects.
  • Nutmeg oil has a local stimulating effect on the gastrointestinal tract, a small amount can promote gastric juice secretion and intestinal peristalsis, and a large amount has an inhibitory effect.
  • Nutmeg oil is a powerful monoamine oxidase inhibitor with significant anesthetic properties.
  • The myristyl ether and deoxy-diisoeugenol isolated from the nutmeg coat can inhibit the lipid peroxidation in the liver by directly scavenging free radicals and active oxygen.
  • Myristyl ether has a moderately exciting effect on the human brain, and nutmeg has a hallucinogenic effect on normal people.
