Via the ancient tradition of bullshitting over beers, hangover cures have been passed down from generation to generation. Everyone has their own panacea, and most of them are as firmly planted in science as the knowledge that standing on your head and drinking water cures the hiccups.
However, some hangover cures are better than others. In On Drink, Kingsley Amis offers a multi-step cure that includes performing "the sexual act as vigorously as you can. The exercise will do you good." On par with that cure is a new one out of South Korea called the Gyeondyo bar, a grapefruit-flavored ice cream bar with oriental raisin tree fruit juice (that's the actual name).
Yes, ice cream will cure your hangover. At least, that's the idea behind this, the greatest idea ever.
South Korea is Asia's biggest alcohol consumer per capita. Booze is big business, and so are hangover remedies. The market, which includes a plethora of drinks and pills, rakes in over $126 million USD in annual sales, according to Reuters.
