Alibaba.com on July 8 announced it is tightening up its policies governing the sale of over-the-counter (OTC) drugs as well as sexual enhancement foods and supplements. The move is part of a company-wide effort to verify the safety and reliability of items for sale on the e-commerce website.

About 7,700 suppliers using Alibaba.com sell OTC drugs. Those merchants now have two months to provide the company’s Trust and Safety Team with documentation proving that each of the drugs on offer has been properly licensed and is sourced from a legitimate channel.

In addition to updating its regulation of OTC medicines, the site will no longer allow the sale of any food or herbs that claim to enhance sexual performance. Many products listed as food or supplements make unauthorized medicinal claims, contain dangerous substances such as psychotropic drugs, or infringe on intellectual property rights, according to the company.

Sellers have five days to remove the banned products from their stores. “[After the deadlines], non-conforming content will be removed, while repeat offenders may have their posting rights curtailed per our guidelines,” said Daniel Draper, a member of Alibaba.com’s Trust and Safety Team.

Although the website bans the sale of prescription drugs, illegal fakes of popular pharmaceuticals such as Viagra and Xanax have popped up for sale on Alibaba.com in the past. The company has been trying to keep the site illegal-drug free. “As a neutral e-commerce platform, we are committed to work with pharmaceutical regulators, legal regulators and pharmaceutical experts to prohibit and remove fake drug listings from the platform,” said Jasper Chan, a company spokeswoman.
