Slim 10

Slim 10 (Chinese: 御芝堂; pinyin: Yuzhitang) was a popular dieting pill produced by Yuzhitang Health Products of Guangdong, People's Republic of China. In 2002, the product gained notoriety for cases of thyroid problems, liver failure, and deaths in Asia as a result of its consumption.[1][2][3]

The product label claimed that the ingredients contained only natural extracts,[4] and was originally cleared for sale by authorities.[5] It was tested and found to contain fenfluramine and nicotinamide that was banned by authorities in several Asian countries but had not been discovered in previous tests—the authorities then ordered the product to be pulled from their shelves and conducted criminal investigation.[6] Fenfluramine is a substance that was first outlawed in the United States due to associations with severe health hazards.[1]
