Nutmeg is a hallucinogen.

Summary: Nutmeg isn't just a tasty spice for your baked goods—it can actually cause hallucinations! It contains a chemical called myristicin, which messes with your central nervous system by making your body produce too much of a hormone called norepinephrine. While people in the Middle Ages used it to try and see visions, taking too much today will just make you sick. A nutmeg overdose causes dizziness, confusion, and a racing heart. Fun history fact: In the 1600s, the Dutch actually traded the island of Manhattan to the British just so they could control a tiny island that grew nutmeg!
