Famed prophet Nostradamus allegedly wrote his apocalyptic predictions while incredibly high on nutmeg

The nutmeg story behind Nostradamus’s visions

Accounts linking Nostradamus to large doses of nutmeg describe a possible way to provoke visions, but the claim is not firmly established. The spice does contain myristicin, a natural chemical that can affect the nervous system when consumed in unusually large amounts. That makes the story plausible-sounding—but it does not show that Nostradamus actually used nutmeg this way, or that it shaped his prophecies.

Why the effect is unpredictable

Myristicin’s effects are not like switching on a clear, controlled vision. In excessive quantities, nutmeg can cause confusion or hallucinations alongside unpleasant physical symptoms such as nausea and dizziness. The experience can be delayed and unpredictable, and the chemistry behind it is not fully understood. A powerful or unusual mental state, in other words, would not necessarily produce coherent predictions.

That distinction matters because a familiar kitchen spice can sound harmless even when the dose changes its risks. Nutmeg in food is not equivalent to taking enough to alter perception. The enduring tale says as much about the allure of explaining prophecy through an intoxicating substance as it does about anything we can reliably know of Nostradamus’s methods.
