title: Extracts of rhinoceros horn are not antipyretic in rabbits.
abstract: We administered extracts of the horn of the African Black rhinoceros intragastrically to 7 rabbits, at the same time as injecting bacterial lipopolysaccharide (LPS) intravenously into the rabbits to produce fever. At a dose of horn (50 mg/kg) similar to that allegedly used to reduce human fever, and at ten times that dose, the fever response to LPS was not significantly different (P > 0.05, t-test) to the response to LPS injection when boiled water was administered instead of horn extract. The known antipyretic indomethacin, however, at a dose of 10 mg/kg significantly reduced the response to LPS.
