Özet:    Many herbal teas are known to have positive health effects. However, there are limited studies on their mineral contents. In this study, the mineral contents (Zn, Mn, Na, K, Cl, Ca, Fe, Mg and P) of thyme (Thymus vulgaris L.), mint (Mentha piperita), senna (Cassia angustifolia), rosemary (Rosmarinus officinalis), fennel (Foeniculum vulgare), chamomile (Matricaria chamomilla), linden (Tilia vulgaris), sage (Salvia officinalis), greens (Camellia sinensis) and nettle (Urtica dioical) herbs used for medicinal purposes in Turkey and their infusions were investigated. The extraction rate of minerals into herbal tea by infusion method was determined. The mineral contents of herbs and their infusions showed a wide variability. The extractability of minerals varied between 41.57 % and 60.37 %. The mineral with the highest extractability was K (32.73 % -70.69 %) and the lowest one was Fe (12.05 % - 0.39 %). Regular herbal tea consumption can contribute to meeting the daily mineral requirements.
