Abstract

It has been determined the concentration of fourteen micro and macrominerals (Al, Ca, Co, Cr, Cu, Fe, K, Li, Mg, Mn, Na, P, Se, and Zn) in both crude drugs and infusions of <i>Melissa officinalis</i> L., Lamiaceae, <i>Nepeta cataria</i> L., Lamiaceae, <i>Passiflora caerulea</i> L., Passifloraceae, <i>Tilia x moltkei</i> Späth ex C.K. Schneid., Tiliaceae, and <i>Valeriana officinalis</i> L., Caprifoliaceae. These herbs are widely consumed by its sedative properties, either alone or in herb mixtures. All measurements were performed using an inductively coupled plasma optical emission spectrometer (ICP-OES). The products were obtained from regional markets, mainly in San Luis province (Argentina). The estimated daily intake was compared with current recommendations. All products and its infusions were included within the upper tolerable limits for minerals, in trace elements such as toxic elements present at low levels.
