myristicin

Myristicin is a chemical compound found in nutmeg and mace, which are spices derived from the fruit of the Myristica fragrans tree. Mace is the dried aril, or lacy covering, of the nutmeg seed, while nutmeg is the seed itself. Both spices have a warm, pungent fragrance and taste, and are used to flavor various foods and beverages.123

Myristicin is a component of the essential oil in nutmeg and mace. While generally safe in culinary amounts, myristicin can be poisonous and have psychoactive effects, including hallucinogenic properties, when consumed in large quantities. Historically, nutmeg and mace have been used in traditional medicine for digestive issues and other ailments.132
