Overview
Arrowheads from South Africa (6,700 years old) and Egypt (4,000 years old) tested positive for toxic plant glycosides, indicating historic use of poison in hunting.
Chemical residues matched Boophone disticha, a South African toxic plant known as gifbol, confirming specific plant-based poisoning.
Detected alkaloids—buphanidrine and epibuphanisine—identified the poison compounds on the artifacts.
Historical and archaeological evidence suggests poisoned arrows were intended to incapacitate prey rather than kill instantly.
Symptoms of human exposure include nausea, muscle weakness, respiratory problems, rapid pulse and potential coma, depending on dose.
