Thyme is an important culinary and medicinal herb. In folk medicine, it has long tradition as a spasmolytic, stomachic, carminative, diuretic, urinary disinfectant and vermifuge. Extract were prepared using the conditions prescribed for tincture according to Pharmacopoeia. Based on the qualitatively and quantitatively analysis of active ingredients using GC and HPLC methods, the physiological effect was estimated and the recommended dosage determined. Tincture was added aseptically to commercially produce bottled pills, dark and alcohol-free beers, taking into account the recommended daily doses and sensory acceptability.
