The health benefits of nutmeg oil may include its ability to relieve stress, pain, menstrual cramps, heart disorders, indigestion, blood pressure, cough, and bad breath. The health benefits of nutmeg oil can be attributed to its medicinal properties such as its role as a sedative, stimulant, relaxing, anti-inflammatory, antiseptic, and bactericidal substance.
Nutmeg has the Latin name Myristica fragrans. It may also be known by other common names in various countries as mace, muscadier, magic, muskatbaum, noz moscada, myristica, nuez moscada, and nux moschata.
The nutmeg tree grows very tall and may reach up to seventy feet in height. Nutmeg oil may be obtained from the seed of the nutmeg tree fruit. The fruit, when dried, produces nutmeg (the seed) and mace (the covering). Traditionally, nutmeg was believed to be effective against the plague and hence it was popular during the Elizabethan era.
