Aphrodisiacs around the globe
Here's a strange one. These little beetles are sometimes crushed up and given to farm animals to promote mating. Apparently, someone decided it will work on humans. Crazy, right? Maybe not. According to a report published by the Mayo Clinic, cantharidin, a chemical found in this little beetle, "has been used for millennia as a sexual stimulant." However, the very same chemical can also cause kidney damage if used incorrectly.
