Recent research has revealed startling insights into the practices associated with child sacrifices in the Inca Empire, particularly regarding the use of psychoactive substances. A team of researchers from the University of Warsaw has conducted an extensive analysis of hair and nail samples from eight mummies, dating back approximately 500 years, found in high-altitude regions of Peru and Argentina.

The study focuses on the ceremonial practice known as capacocha, which involved sacrifices of children and young women to appease Inca deities. This ritual was a fundamental aspect of the Inca culture from the 13th to the 16th century, and although some details have been documented, previous research primarily identified coca leaves in the mummies without delving deeper into the composition of other substances used during the ceremonies.
Dr. Dagmara Socha, who led the research, explained that the objective was to explore a wider variety of psychoactive substances that might have been administered to these children. The scientists achieved this through toxicological analysis, which enabled them to identify chemical traces embedded within the keratin of hair and nails. These remnants, preserved over centuries, have provided a window into the rituals of the past.
The findings were significant; cocaine was detected in all eight samples, indicating that the children had chewed coca leaves prior to their sacrifice. Coca leaves served as offerings to Inca gods, but they also played a practical role in combating altitude sickness and fatigue as the children ascended the mountainous regions where the rituals were performed. This aligns with historical accounts that suggest the use of coca leaves was commonplace in Inca society, especially in elevated terrains.
In addition to cocaine, evidence of alcohol consumption was found in four of the mummies, likely deriving from a corn beer known as chicha. Historical records suggest that this beverage was sometimes provided to the children beforehand as a way to calm them, making the unfathomable experience of sacrifice less daunting. The researchers also uncovered traces of harmine, an alkaloid associated with plants used in the preparation of ayahuasca, a well-known psychoactive mixture. Notably, harmine can be toxic in high doses, adding another layer of complexity to the sacrificial practices.
This research suggests that the capacocha rituals were not uniformly practiced across the Inca Empire; instead, variations may have existed, tailored to different local customs and traditions. Dr. Socha highlighted the importance of adapting the ritual methodologies to local cultures, indicating that the Incas were likely influenced by regional religious practices.
The significance of these findings extends beyond the individual mummies analysed. They paint a broader picture of Inca religious life and the sophisticated nature of their sacrificial rituals. “Five hundred years after these children were sacrificed during one of the most important Inca rituals, new technologies are allowing us to uncover details of their lives and Inca religious practices,” Dr. Socha noted.
By utilising contemporary toxicological methods, the researchers are shedding light on historical practices that were often shrouded in mystery. The nuanced understanding of the capacocha rituals, as revealed through this study, reinforces the idea that ancient civilisations like the Incas were deeply interconnected with their environment, utilising available resources to navigate both their spiritual and physical worlds.
This research marks a significant contribution to the understanding of ancient Inca practices and highlights the extensive use of psychoactive substances in their cultural rituals. As advancements in technology continue to evolve, further insights into the complexities of ancient civilisations may soon follow, helping us better appreciate the intricate tapestry of human history.
