Abstract : Medicinal plants remain an important component of primary healthcare in many developing countries, including Nigeria, due to their accessibility, affordability, and long-standing therapeutic use. However, the safety of herbal materials is increasingly threatened by environmental contamination, particularly from trace and toxic elements that may accumulate in plant tissues. This study assessed the trace element concentrations and associated health risks of selected medicinal plant leaves collected from fifteen locations within Gombe Metropolis, Northeastern, Nigeria. Fifteen medicinal plant species were sampled, identified, air-dried, pulverized, and analyzed using Energy Dispersive X-Ray Fluorescence (EDXRF).

Keywords : Trace Elements, Medicinal Plants, Heavy Metals, Health Risk Assessment, Gombe Metropolis.
