Bolibao, a "miracle" treatment that comes in the form of a drink, was accused in a television documentary of causing gynaecological problems and doing nothing that it promised.
Gao Xuemin, an expert in traditional Chinese medicine, was quoted by Central China Television on Sunday as saying that claims the product could enlarge breasts were "groundless." The product, made by a Beijing-based company, has been on sale on TV since the end of last year at a price of 99 yuan (USD 12) per box. It has been advertised on 17 local television stations, while on the Internet it is available for as little as 28 yuan (USD 3.5). The company says it takes at least 10 boxes to have an impact.
"Bolibao has been dominating the bestsellers list since the end of last year," said one of the product's sales agents was quoted as saying by 'China Daily'.
He declined to be named or reveal how much he sells each day, though he said sales have not fallen following the adverse television programme.
Haidian Sub-Bureau of Beijing Administration of Industry and Commerce has received dozens of complaints from consumers in recent months saying that the product is ineffective.
Xu Ying, an official of the sub-bureau, said that product sample has been sent to a professional institute for quality check and initial analysis.
"The quality report is expected to be completed in two days and will be made public," she said.
