The search for the perfect hangover fix may not be over just yet, suggests a new meta-analysis by British researchers.
The study assessed 23 popular hangover cures such as clove extract, tolfenamic acid, Japanese raisin tree fruit extract, red ginseng, Korean pear juice, among others across 21 previously conducted studies and concluded that there is not enough evidence to support the effectiveness of these cures.

Only seven of the substances tested showed any signs of improving symptoms, but even this was deemed “low-quality” evidence by the researchers.
Published in the journal Addiction, the study included drinkers from the UK, US, Australia, India and Finland. While scientists said we need much more rigorous assessment for all the cures, clove extract, Tolfenamic acid and Pyritinol were the top three cures showing the strongest evidence of combatting hangover symptoms, said the team.
