“We’re not suggesting that everyone starts using tea leaves as a water filter,” said co-author Vinayak Dravid, who studies sorbent materials at Northwestern University. “Our goal was to ...

Researchers from Northwestern University have found that tea leaves absorb certain harmful metals from water, such as lead and cadmium, preventing us from ingesting them. The researchers emphasize ...

Vinayak Dravid (right), professor of materials science at Northwestern University, oversaw a team of scientists that discovered tea leaves can absorb and filter out harmful metals, including lead.

Heavy metal ions stick to, or adsorb to, the surface of the tea leaves, where they stay trapped until the used tea bag is disposed of. The study was published in the journal ACS Food Science ...

Green tea is attained from tea leaves picked during spring. The tea is novel in that it is the most minimally oxidated of all teas, with the leaves dried shortly after being picked and then pan ...
