Worldwide, certain plants and animals are being decimated because of their traditional use as sexual stimulants. Millions of dollars are spent on medical research to discover the neurotransmitter for desire, and some men think nothing of injecting a syringe into their penis. People will try anything to enhance their sex lives. Anything may include rhinoceros horn, historically considered an aphrodisiac. The notion more than likely comes from the horn's phallic shape.
Mimetic consumption applies to antlers, sea cucumbers, ginseng and snake blood, among other things.
Reproductive organs from various animals also follow this logic. The penis and testicles of tigers, elk, horses, dogs, seals and rabbits find their way into the Far East apothecary. Spanish fly is another mythical aphrodisiac that just won't die. It supposedly turns innocent maidens into nymphomaniacs. In truth, Spanish fly is a powerful poison.
