Article Abstract
Stachys lavandulifolia Vahl. subsp. lavandulifolia (Lamiaceae) is widely used in south Anatolia as a herbal tea. It is used for the treatment of gastrointestinal and respiratory disorders. Constituents of the essential oil obtained by hydrodistillation were analyzed both by GC-FID and GC/MS, simultaneously. Thirty-seven compounds representing 98.3% of the oil were characterized. Beta-Phellandrene (27%), alpha-pinene (18.5%) and germacrene-D (13%) were found as major components of the oil. Anticandidal, antibacterial and antioxidant properties of the oil and the prepared infusion were evaluated using several methods. The oil exhibited good inhibitory activity on Candida tropicalis (MIC 0.094 mg/mL). Staphylococcus aureus and Salmonella typhimurium growths were also inhibited by the oil at a concentration of 0.375 mg/mL. The prepared infusion of the flowering aerial parts showed weak antimicrobial effects against all the tested microorganisms, but demonstrated a remarkably radical scavenging activity (IC50: 3.9 microg/mL).

Article Synopsis
- Tea is widely consumed globally, but it can contain harmful impurities; this research aims to analyze 16 trace elements in brewed tea to assess health risks.
- The study found that manganese (Mn) had the highest concentrations in black and green teas, while the brewed tea from Stachys lavandulifolia showed the highest boron (B) levels; tea bags had more contaminants than unpackaged tea.
- Despite higher metal levels in Iranian tea compared to imports, all tested samples had heavy metal concentrations below international safety limits, indicating a low non-carcinogenic risk for consumers, even with longer brewing times.
