Archaeologists identify drugs used in Inca sacrificial rituals through mummy analysis
Scientists analyzed toxicological samples from eight Inca mummies to identify psychoactive substances given during the capacocha ritual at mountain shrines across the empire.

Toxicological findings on remains
Researchers examined chemicals embedded in the hair and nails of sacrificed individuals. Earlier studies often produced negative results or focused only on coca leaves. This new analysis reveals a broader range of psychoactive substances administered before death.
Purpose of substance use
The study suggests these drugs were given to enhance prophetic abilities during the ceremony. Children and young women served as intermediaries between living people and the divine. Their consumption of plants was part of a sacred act of veneration for deities.
