Ancient Teeth Reveal Betel Nut Use Dates Back 25,000 Years

According to a report by Khaosod Online, citing research from Griffith University in Australia, scientists have identified evidence of betel nut chewing dating back 25,000 years. This discovery, made in collaboration with Indonesian archaeologists, suggests that the use of this psychoactive substance began long before the Neolithic or Bronze Age, which were previously thought to be the origins of the practice around 3,500 years ago.

The study analyzed two prehistoric skeletons found on the island of Sulawesi, Indonesia. Researchers observed deep, curved grooves on the teeth of these hunter-gatherers, which are consistent with the regular consumption of whole betel nuts. Furthermore, biochemical analysis of the dental tissue confirmed the presence of arecoline, a stimulant that affects the nervous system and brain function.

For those interested in the cultural history of the Asia-Pacific region, this finding highlights that betel nut is one of the world’s oldest psychoactive substances, with a history spanning tens of thousands of years prior to the advent of agriculture. While the physical evidence on the teeth and the chemical traces provide a strong link to ancient habits, researchers continue to study these prehistoric remains to further understand the social and behavioral patterns of early human populations. This discovery serves as a significant milestone in tracing the origins of ancient stimulants in the region.
