TOKYO, Japan – Before a night out on the town, a key beverage ingredient is standing out among a “dizzying array” of tonics and elixirs that claim to be hangover cures, writes the Inquirer.net.

These bottled drinks are a multimillion dollar business in Japan, and the country’s convenience stores are keeping shelves stocked with brands such as Ukon no Chikara, “whose faithful believe that gulping down the 205 yen ($1.70) turmeric-based recipe before a night out will make the next day a breeze,” notes the news source, adding that turmeric is believed to work as an antioxidant and anti-inflammatory aid.

There’s also the “reputedly dreadful tasting Solmac,” which is a mixture of leaf extracts, turmeric, ginseng and licorice.

Whichever bottled hangover cure consumers reach for, the market for these beverages is estimated at $178 million in 2015, and c-stores are helping these products thrive. “People find it easier to go to a convenience store rather than the pharmacy, and it has also helped brand awareness,” a Zeria Pharmaceutical spokesman told the news source. “Convenience store sales have really boosted our revenues. The best sales month is December.”

Shun Yokoyama, an analyst specializing in health drinks at marketing research firm Fuji Keizai, told the news source that demand for “liquid replenishers” is likely to remain strong. “One key feature of the Japanese market is that there’s a high demand for drinks to recover from situations that are bad for your health, such as a hangover,” he said, adding, “When you look at Japan from a global perspective, supplements don’t sell so well. But consumers want something to recover their health by replenishing their nutrition through drinks.”
