Is there a risk of trace element contamination in herbal preparations? A test study on the lichen Cetraria islandica
Lichens are a source of unique secondary metabolites, which have been proved to have many biological properties with possible pharmaceutical roles, including e.g. antioxidant, antimicrobial, antifungal or anti-inflammatory activities and to be worth of consideration for potential human use. However,...
