"Today it seems a substantial minority of consumers want these myths to be true, even if there is no empirical evidence that they are," said researcher Dirk Lachenmeier, a chemist with the Chemical and Veterinary Investigation Laboratory of Karlsruhe in Germany.
Lachenmeier and his colleagues analyzed 13 samples of absinthe from old, sealed bottles in France, Switzerland, Italy, Spain, the Netherlands and the United States dated back to the early 1900s before the ban. After uncorking the bottles, they found relatively small concentrations of thujone in that absinthe, about the same as those in modern varieties.
Laboratory tests found no other compound that could explain absinthe's effects. "All things considered, nothing besides ethanol was found in the absinthes that was able to explain the syndrome of absinthism," Lachenmeier said. (Ethanol is a word for common drinking alcohol.)
The scientists are set to detail their findings in the May 14 issue of the Journal of Agricultural and Food Chemistry.
