North Korea has developed a "super drink" that, it says, can multiply brain cells and stop skin ageing.
The secretive state's official news agency, KCNA, says the drink contains 60 kinds of "microelements" extracted from more than 30 species of plants.
It attracted "much interest from Chinese, German and other businessmen" at a trade fair in Pyongyang last month, the agency reports.
It was developed by a joint venture fruit juice company.
KCNA says: "It, with effects of both preventive and curative treatment, helps improve mental and retentive faculties by multiplying brain cells.
"It also protects skin from wrinkles and black spots and prevents such geriatric diseases as cerebral haemorrhage, myocardium and brain infarction by removing acid effete matters in time.
"It, much higher than quality cosmetics in anti-oxidation capacity, is efficacious for different skin diseases, including allergic dermatitis. It also makes skin fair.
"The drink has no side-effect."
The agency quotes a company manager, Jong Song Ho, as saying the drink has "proved efficacious among workers of such industrial establishments as thermal power station and smeltery and at medical institutions".
