- Abstract
The content of certain metals in 13 medicinal teas made from 16 plant species was measured by flame photometer and atomic absorption spectrometer with flame methods. The measurements were evaluated against metal intake levels recommended by health authorities. The results indicate that the medicinal teas tested, regularly consumed by inhabitants of the Urubueua de Fátima River Community, Abaetetuba-Para, Brazil, present no risk of poisoning people older than six months. However, decoctions of Mentha sp., Eleutherine bulbosa, Euterpe oleracea, Piper callosum and Hyptis mutabilis, mostly given to children, had Mn values potentially exceeding the recommended maximum intake for infants in the 0-6 months age group, in the quantities customarily administered. Consequently, studies are needed to assess bioavailability for safe human consumption. Results also showed the consumption of medicinal tea alone is not enough to supply an adult's daily metal requirements or treat deficiencies. Additionally, cures emphasized by interviewed Community members might be associated with the bioactivity of organic substances that the medicinal teas contain.
