EurekAlert! -- Scientists in China have discovered that roots of a plant used a century ago during the great Spanish influenza pandemic contains substances with powerful effects in laboratory experiments in killing the H1N1 swine flu virus that now threatens the world. The plant has a pleasant onion-like taste when cooked, but when raw it has sap so foul-smelling that some call it the “Dung of the Devil” plant. Their report is scheduled for the Sept. 25 issue of ACS’ Journal of Natural Products, a monthly publication.
