The aim of this study was the determination of mineral content in spontaneous flowering stems and rosette leaves of mountain tea (Sideritis scardica Griseb.) collected in four different localities in North Macedonia. The plant material was air-dried, packed in paper bags, and kept in a dark and cold place until analysis. Samples were digested in a microwave system by the wet digestion method. The minerals were determined by the application of inductively coupled plasma–atomic emission spectrometry (ICP-AES) and inductively coupled plasma–mass spectrometry (ICP-MS). The rosette leaves exhibit a very similar mineral content profile to the flowering stems of S. scardica, and accordingly can be recommended as a plant material of this endemic aromatic plant
