Pilot Study of Trace Elements in the Infusion of Medicinal Plants Used for Diabetes Treatment

Table 3

Average concentrations (µg/g) of fourteen measured elements in five types of medicinal plants, mean ± SD (n = 4) with a 95% confidence level. The infusion was one gram of each plant boiled in deionized water for ten minutes.
