Dracocephalum imberbe Bunge (Lamiaceae) is a perennial species endemic to the Alai Range, Kyrgyzstan, traditionally used in ethnomedicine. Its aerial parts are employed in decoctions and infusions for respiratory and gastrointestinal ailments and exhibit mild anti-inflammatory effects. Quantitative assessment of macro- and micronutrient composition in both aerial and root tissues is critical for evaluating its biochemical profile, pharmacological potential, and safety. Analytical results indicate that all investigated elements in leaves and roots fall within acceptable ranges for medicinal plants, confirming the ecological purity of the samples. The aerial parts exhibit high concentrations of essential macronutrients, including potassium (K), calcium (Ca), magnesium (Mg), and phosphorus (P), while toxic elements such as cadmium (Cd), lead (Pb), mercury (Hg), and arsenic (As) remain at minimal levels. Slight deviations include marginally reduced copper (Cu) and values of chromium (Cr) and selenium (Se) approaching the upper limits of normative ranges, without exceeding permissible thresholds. Roots demonstrate elevated accumulation of barium (Ba), strontium (Sr), sodium (Na), and calcium (Ca), reflecting typical patterns of ion storage in subterranean tissues. Although lead (Pb) and molybdenum (Mo) concentrations are higher in roots than in aerial parts, they remain within acceptable limits. Comparative analysis underscores distinct element distribution between plant organs, with leaves preferentially accumulating essential macronutrients and roots concentrating certain non-essential or trace elements. Overall, D. imberbe exhibits a stable elemental profile, highlighting its suitability for medicinal applications and supporting its use in ethnopharmacology. These findings provide a foundation for quality assessment, standardization, and optimization as a botanical resource.
