Could a Chinese pill end your hangover… and cure alcoholism? The trick is to keep you from getting drunk in the first place.

Imagine a pill that could instantly sober you up no matter how much you’ve had to drink, or a hangover cure that worked minutes after swallowing it. Hardened drinkers rejoice: researchers are about to begin human trials on an “alcohol antidote” that may soon offer a cure to alcoholism, reports New Scientist.

The drug is a chemical called dihydromyricetin, or DHM, and is derived from a Chinese variety of the oriental raisin tree, which has been used for at least 500 years in China as an effective hangover cure. So far the extract has only been tested on boozing rats, but with promising results.

“DHM will reduce the degree of drunkenness for the amount of alcohol drunk and will definitely reduce the hangover symptoms,” said Jing Liang, lead researcher in the study. “In time, it will reduce [an alcoholic’s] desire for alcohol.”
