Jan Bartek – AncientPages.com – For 1000’s of years, people have used psychoactive vegetation for his or her narcotic results. In Thailand, archaeological proof has revealed the presence of betel nuts at burial websites. These vegetation are identified for his or her stimulant properties and have been an integral a part of cultural practices all through historical past.

Now, a global group of researchers has performed a examine on 4,000-year-old enamel to realize insights into historic practices.
They found traces of compounds from betel nuts, suggesting that the apply of betel nut chewing has been prevalent within the nation for 1000’s of years or probably even longer. This examine is pioneering in its skill to establish ‘archaeologically invisible’ cues inside dental plaque, thereby uncovering historic behaviors and practices that may have in any other case remained unknown over time.
In Southeast Asia, the apply of chewing betel nuts has a protracted historical past courting again to historic occasions.
The vegetation comprise compounds that may improve alertness, vitality, euphoria, and rest in customers. Whereas this custom is turning into much less prevalent right this moment, it stays an integral a part of social and cultural customs which have endured for millennia. A typical impact of chewing betel nuts is the staining of enamel in shades starting from darkish reddish-brown to black.
But, enamel with out staining could not imply that folks didn’t chew betel nuts.
Utilizing a brand new methodology, the researchers examined historic dental plaque from Bronze Age Thailand and located proof of betel nut chewing.

Dr. Piyawit Moonkham, an anthropological archaeologist from Chiang Mai College in Thailand, reported in a examine revealed in Frontiers in Environmental Archaeology that plant derivatives have been found in dental calculus from a 4,000-year-old burial web site at Nong Ratchawat, Thailand.
This discovering represents the earliest direct biomolecular proof of betel nut use in Southeast Asia.
“We display that dental calculus can protect chemical signatures of psychoactive plant use for millennia, even when standard archaeological proof is totally absent,” added Dr Shannon Tushingham, the senior creator, who’s the affiliate curator of anthropology on the California Academy of Sciences.
“In essence, we’ve developed a option to make the invisible seen—revealing behaviors and practices which were misplaced to time for 4,000 years.”
