Nutmeg is the seed or ground spice of several species of the genus Myristica. Myristica fragrans is a dark-leaved evergreen tree cultivated for two spices derived from its fruit: nutmeg, from its seed, and mace, from the seed covering.
The spice nutmeg has a distinctive pungent fragrance and a warm slightly sweet taste; it is used to flavour many kinds of baked goods, confections, puddings, potatoes, meats, sausages, sauces, vegetables, and such beverages as eggnog. The fleshy arils surrounding the nutmeg seed are the source of the spice mace.
Nutmeg is found to have health benefits, including its ability to relieve pain, soothe indigestion, strengthen cognitive function, detoxify the body, boost skin health, alleviate oral conditions, reduce insomnia, increase immune system function, and prevent leukemia, and improve blood circulation.
