NORTH Korea has claimed to have invented many things, from curing ebola and Sars to AIDS and even cancer.

Now it says it has another feather to add to its cap: hangover-free alcohol.

According to reports, scientists in the communist state claim to have developed a 30 to 40 per cent proof liquor that will not leave you feeling seedy in the morning.

The secret?

The drink is supposedly made from a type of indigenous ginseng called insam and glutinous rice — rather than sugar — and had reportedly won an award.

A recent edition of the Pyongyang Times said the drink, Koryo Liquor, used a cunning combination of six-year-old, top quality ginseng and “scorched glutinous rice”.

The article, entitled “Liquor wins quality medal for preserving national smack”, said the Taedonggang Foodstuff Factory had been working for years on the elixir, the BBC reported.

The drink derives from Kaesong Koryo insam, a natural herb thought to have medicinal properties.

Replacing sugar with the scorched, glutinous rice removed the bitterness from the insam and, crucially, the hangover, the newspaper reportedly wrote.

“Koryo Liquor, which is made of six-year-old Kaesong Koryo insam, known as being highest in medicinal effect, and the scorched rice, is highly appreciated by experts and lovers as it is suave and causes no hangover,” the BBC reported.

The North Korean media has a long record of making extraordinary claims of the country’s achievements in pretty much any field from medicine to sport and farming.

Last year, the North’s official KCNA news agency said scientists had developed a drug, with ginseng again a major component, that could cure AIDS, ebola and MERS.

The North’s most recent, and literal, bombshell was the claim that its latest nuclear test — conducted January 6 — was of a powerful hydrogen bomb.

International experts have largely dismissed the idea, saying the yield from the test was far too low for a full-fledged thermonuclear device.

North Korea is not the first to claim to have developed a hangover-free alcohol.

In 2014, three Californian college students developed Prime, a drinks supplement which could break down the toxic byproducts of alcohol and prevent waking up with a hangover, CNBC reported.

However the group only managed to crowd-fund 13 per cent of their $20,000 target needed to develop the product.
