Most hangover remedies not backed up by science, study finds

Many people believe in hangover cures to help them bounce back after a night of indulgence. But according to a new systematic review, there is little evidence that these substances can treat or prevent the head-throbbing, nauseous after-effects of drinking.

On New Year's day, researchers published their evaluation of 21 studies in the journal Addiction. These studies looked at 23 different substances, including clove extract, red ginseng, vitamin supplements, and Korean pear juice - all alleged to either prevent or treat hangovers (veisalgia). The studies involved 386 participants.
