RIYADH: A study published in the journal Communications Biology has revealed the earliest known use of the harmal plant (peganum harmala) — dating back about 2,700 years to the Iron Age — is based on findings from the ancient settlement of Qurayyah in ’s Tabuk region, according to the Saudi Heritage Commission.
The research was conducted jointly by the Saudi Heritage Commission, the Max Planck Institute for Evolutionary Anthropology in Germany, and the University of Vienna in Austria. It examined the therapeutic and social aspects of ancient practices in the Arabian Peninsula.
