Abstract
Elemental
analysis of herbal teas and their tisanes is aimed at assessing their
quality and safety in reference to specific food safety regulations and
evaluating their nutritional value. This survey is dedicated to atomic
spectroscopy and mass spectrometry element detection methods and sample
preparation procedures used in elemental analysis of herbal teas and
medicinal plant formulations. Referring to original works from the last
15 years, particular attention has been paid to tisane preparation,
sample matrix decomposition, calibration and quality assurance of
results in elemental analysis of herbal teas by different atomic and
mass spectrometry methods. In addition, possible sources of elements in
herbal teas and medicinal plant formulations have been discussed.
