Nutmeg is the dried kernal of Myristica fragrans, a tree native to the Spice Islands, near New Guinea. Now cultivated in many places, the tree grows to about fifty feet high and bears seeds for up to sixty years. Its fruit looks much like a peach and contains a brownish-purple, shiny kernel encased within a bright orange-red or red covering. The covering, or aril, is used for production of mace; the seed, dried in the sun for about two months and turned over each day, becomes nutmeg. Both the kernel and its covering contain psychoactive components within their oils. (Psychedelics Encyclopedia)

Nutmeg is used in the U.S. mainly as a garnish during Christmas festivities. It appears in the Hindu Pharmacopoeia as a treatment for fever, asthma and heart disease. Since the seventh century A.D., Arab physicians have used it for digestive disorders, kidney disease and lymphatic ailments. Yemeni men are said to consume nutmeg to increase and maintain their sexual vigor.
