The tamango is an Italian cocktail infused with roselle leaves and a variety of mysterious African roots and plants^{[clarification needed]} which purportedly give it a hallucinogenic effect; it is 70% alcohol and is the specialty of a pub close to the University of Turin. The name is taken from an 1829 short story (later made into a 1958 film) of a slave ship revolt by French author Prosper Mérimée.^[1]
