A landmark scientific study published in the international "Communications Biology" journal revealed the earliest known use of the harmal plant (Peganum harmala), dating back around 2,700 years to the Iron Age, based on archaeological findings from the ancient settlement of Qurayyah in Saudi Arabia’s Tabuk Region, according to a Saudi Heritage Commission press release, SPA reported.
Conducted as part of a joint research effort by the Saudi Heritage Commission, the Max Planck Institute for Evolutionary Anthropology in Germany, and the University of Vienna in Austria, the study explores the therapeutic and social dimensions of ancient practices in the Arabian Peninsula, underscoring the Kingdom’s commitment to advancing scientific understanding of its cultural heritage.
Using high-performance liquid chromatography–mass spectrometry (LC-MS/MS), researchers performed advanced chemical analyses on organic residues preserved inside pottery incense burners. These analyses detected alkaloids from the harmal plant, providing physical evidence of its use in fumigation rituals for therapeutic purposes.
The harmal plant, also known locally as rue, is recognized for its antibacterial and healing properties. Its documented use at Qurayyah not only reflects early medicinal knowledge but also highlights the continuity of traditional practices in the region.
This discovery further underscores the longstanding cultural and therapeutic traditions of the Arabian Peninsula and demonstrates the Saudi Heritage Commission’s ongoing commitment to international research collaboration.
This research aligns with the broader goals of the Saudi Ministry of Culture to support pioneering initiatives that contribute to the global understanding of human history and to reframe the cultural legacy of the Arabian Peninsula through a modern scientific lens.
