Ancient teeth from Sulawesi preserve evidence consistent with repeatedly holding and chewing betel nut as far back as about 25,000 years.<\/p>\n

Molecular residues and wear converge on the habit, but cannot reconstruct each person\u2019s motive or a community-wide prevalence.<\/p>\n

Evidence<\/h2>\n

Researchers compared molecules in calculus and on tooth surfaces with characteristic staining and wear.<\/p>\n

Date<\/h2>\n

The oldest associated remains reach about 25,000 years, far earlier than the roughly 3,500-year benchmark often cited. It is an archaeological range, not an exact date.<\/p>\n

Motives<\/h2>\n

Stimulation, pain relief and ritual are possibilities; archaeology cannot select one motive.<\/p>\n

Health limit<\/h2>\n

Modern use is linked to oral disease and cancer risk. Antiquity is not evidence of safety or a recommendation.<\/p>\n

Next check<\/h2>\n

Residues from more Southeast Asian sites could map spread and separate routine from ritual use.<\/p>\n
