Powdered rhinoceros horn has often been claimed to have aphrodisiac properties. However, a recent investigation showed no evidence that it has any chemical effect whatsoever on the human nervous system. What is more, in an experiment in which 100 people were given powdered rhinoceros horn and another 100 people were given powdered rice, without knowing what they were taking, more of those taking the rice indicated that they felt an increase in sexual arousal than did those taking the rhinoceros horn. This demonstrates conclusively that rhinoceros horn is not an aphrodisiac.
