Rhinoceros
Horn trade and use
Rhinoceros horns, unlike those of other horned mammals, (which have a bony core), only consist of keratin, similar to human hair and nails. Rhinoceros horns are used in traditional medicines in parts of Asia, and for dagger handles in Yemen and Oman. Esmond Bradley Martin has reported on the trade for dagger handles in Yemen. In Europe, it was historically believed that rhino horns could purify water and could detect poisoned liquids, and likely as an aphrodisiac and an antidote to poison.
