Abstract:

Herbal teas are a popular beverage, that can be prepared very easily (by pouring hot water on various dried herbs). It is very important to monitor and develop a screening methodology for detecting the metal content of both tea plants and herbal tea.

This research aimed to estimate the distribution of metals in different types of herbal teas used in diet therapy. We used atomic absorption spectrometry to determine the concentration trance elements (Fe, Mn, Zn and Cu) of macroelements (Ca and Mg), in various native herbal teas. We used herbal teas collected from Gorj County. These plants are Tilia cordataHypericum perforatum, Ocimum basilicum, and Rosa canina

The study aimed at the determination of the mineral composition of medicinal herbs for evaluation of the coverage of the recommended daily intake of mineral elements by tea. The concentration of these bio- minerals in medicinal herbs shows significant variations determined by the nature and type of herbal tea and bio-elements investigated.
