Quanjian Nature Medicine Technology Development, a Tianjin-based company, has exaggerated the benefits of some of its products, a joint investigation team has found.

The company has been accused of misleading consumers, some of whom were bankrupted or died.

A joint team including the Tianjin Administration for Market Regulation and Tianjin Health Commission is investigating the company.

Kang Yi, vice-mayor of Tianjin and head of the investigation team, said preliminary probes in the past 24 hours have found that Quanjian overplayed the efficacy of some of its products.

He said the team is still looking into a number of other accusations and results will be made public in a timely manner.
