They may have finally found a cure for herpes–licorice (sorry, subscription required). You can’t just eat it, though–you have to mainline it:

Researchers at New York University ran lab tests on white blood cells, some of which were infected with the herpes virus. Exposing the infected cells to the licorice ingredient, glycyrrhizic acid, shuts down LANA. That starts a chain reaction of biochemical changes in the white blood cells, leading to their suicide and the virus’ death. The uninfected cells showed no detrimental effects from glycyrrhizic acid, the researchers report in the March Journal of Clinical Investigation.

Cool.
