Thousands of smuggled drug capsules containing human flesh powder were seized by the South Korean customs department, Monday, Associated Press reported.

Officials said that the capsules were being smuggled, masked as stamina boosting medicine, either by international mail or carried along in luggage between northeast China and Korea.

These capsules, made in northeastern China, contain powdered flesh of dead babies and not the chemical content, as proclaimed, to cure any ailment. Also, people living in South Korea use them as a universal medicine for common diseases, custom officials said in a statement.

The Korean Custom Service said that the flesh was obtained after drying chopped pieces of the dead bodies of babies on a stove and turning them to a powder to fill in the drug capsules.

According to custom officials, the capsules contained bacteria and other harmful ingredients; however, no sickness has been reported so far.

In addition, over 35 such smuggling attempts of about 17,450 capsules have been exposed since August, the report said.

So far, no one has been punished or held in the case as the capsules smuggled were not intended for sale, an officer told AP.

He said that officials are investigating the case and the production details of the product and drugs made from dead fetuses or newborns. However, he refused to divulge the details of how and from where the dead babies were sourced.

According to several reports, the source of such products is northeast China, especially, the Jilin province; however, neither China’s State Food and Drug Administration, nor the Health Ministry were available to comment on the issue, AP said. Also, calls on Monday to Jilin food and drug safety agency were ignored.
