Botanical source

Mace is the aril surrounding the nutmeg seed within the Myristica fragrans fruit. When the fruit ripens, the bright red aril is separated and dried.

Main production: Indonesia (Banda Islands, historically), Grenada (West Indian), Sri Lanka. Mace is traditional in Indonesian, Middle Eastern, and Caribbean spice cuisines.

Family Myristicaceae.


Notes

Mace oil has lower safrole and myristicin than nutmeg oil. However both carry psychoactive risk at high doses.

In cosmetics it is used at very low concentrations as a fragrance fixative. Spicy, warm aroma.
