Myristicin is a natural organic compound present in small amounts in the essential oil of nutmeg and to a lesser extent in other spices such as parsley and dill. Myristicin is a naturally occurring insecticide and acaricide with possible neurotoxic effects on neuroblastoma cells. It has psychoactive properties at doses much higher than used in cooking. Myristicin is a weak inhibitor of monoamine oxidase. It also acts as an anticholinergic.In 1963 Alexander Shulgin speculated that myristicin could be metabolized to MMDA, a psychoactive drug related to MDA, in the liver.[4] This speculation has never been confirmed and studies with the closely related compounds asarone and safrole demonstrated that the proposed transamination reactions did not take place in humans.
