The hangover prevention business must booming because a new product pops up every week it seems. Created by folks with long histories in the nightlife world, canonical branding apparently isn’t the drink’s only well conceived feature. Instead science is pushed as its raison d’etre. The concoction features amino acids, herbs, and minerals, designed first and foremost to combat acetaldehyde — which we’re told is the main cause of those horrible mornings, outside of dehydration. According to the New York Times Diner Journal, the product seems to work as advertised. It can also combat alcohol flush — which Mercy’s site diplomatically explains is an “uncomfortable and embarrassing condition that mainly affects those of Asian descent”. It sounds intriguing, but we did spy a position of “Master Alchemist” listed as part of the senior staff, so we’ll reserve judgment until after we do some testing of our own.
