Poisoned arrows or darts have long been used by cultures all over the world for hunting or warfare. For example, there are recipes for poisoning projective weapons, and deploying them in battle, in Greek and Roman historical documents, as well as references in Greek mythology and Homer’s Iliad and Odyssey. Chinese warriors over the ages did the same, as did the Gauls and Scythians, and some Native American populations.
Archaeologists have now found traces of a plant-based poison on several 60,000-year-old quartz Stone Age arrowheads found in South Africa, according to a new paper published in the journal Science Advances. That would make this the oldest direct evidence of using poisons on projectiles—a cognitively complex hunting strategy—and pushes the timeline for using poison arrows back into the Pleistocene.
The poisons commonly used could be derived from plants or animals (frogs, beetles, venomous lizards). Plant-based examples include curare, a muscle relaxant that paralyzes the victim’s respiratory system, causing death by asphyxiation. Oleander, milkweeds, or inee (onaye) contain cardiac glucosides. In Southeast Asia, the sap or juice of seeds from the ancar tree is smeared on arrowheads, which causes paralysis, convulsions, and cardiac arrest thanks to the presence of toxins like strychnine. Several species of aconite are known for their use as arrow poisons in Siberia and northern Japan.
