Nutmeg: A Comprehensive Guide

Introduction

Nutmeg is a highly prized spice derived from the seeds of the nutmeg tree (Myristica fragrans). This evergreen tree produces two important spice products: nutmeg (the seed) and mace (the dried aril covering the seed). Known for its warm, aromatic flavor, nutmeg has been a key ingredient in global cuisines, traditional medicines, and even perfumery. This article explores nutmeg’s varieties, its fruit and byproducts, health benefits, cultivation, economic importance, and sustainability.
